Thank you so much for going through the basics. I am new to structured text (been doing ladder logic for years) and I started watching another series of ST videos and the gentleman giving the tutorials, while extremely knowledgeable, went right into pretty advanced stuff I cannot grasp at this point. Your vids are EXACTLY what I am looking for. THANKS!!
You are some kind of legend for doing this. If these videos turn out to be as helpful as i suspect they are going to be i will send you beer. Much beer.
If anyone have win8 or newer there can be problems. In that case run Twincat/3.1/system/win8settick.bat in admin mode and reboot. Thanks for the upload. It helps me alot. :)
+Joseph Donohue Thanks. No problem. I found it difficult at first until I learned it, I had a decent introduction from a co-worker, but nothing I could find online was worth a damn, hence this video series. I'm glad you enjoyed it.
Thanks for the tutorial. I've been looking for something like this on RUclips or elsewhere on the net. I'm just getting my feet wet with TwinCAT 3 and the Beckhoff platform. In the process of commissioning a machine right now using Beckhoff hardware. The program itself is pretty basic with using some basic discrete and analog I/O. Not too bad. The next project will be a lot more complex (I think?) as it will utilize two servo motors that will operate in strict velocity mode and also used for positional control. I'm not looking forward to the learning curve so I'm hoping it's not going to be as bad as I think. Hope you've created a video tutorial on motion control. Thanks again.
+Don McKiness Thanks. No motion control videos yet, but that will be my topic if I get around to doing more videos. I don't think it'll happen any time real soon though. Here are some hints: If you buy new beckhoff hardware, use their support. If running servos, dish out the small amount of cash to get the beckhoff NC (PTP) System. Velocity control is pretty easy... You'll want use the MC function blocks... MC Drive and MC2... they are pretty well documented, but may seem overly complicated at first. They are not that bad. You'll need MC_Power to get the drive moving from PLC control. If you use NC, you can use the NC system from the IO section of the project without even needing to write PLC code. With that you can get a lot of things working and get your encoder scaled properly and stuff like that. Once all that is working, move to PLC code at that point so you don't bite off a big chunk all at once. The point of the NC system is to be an abstraction layer between the PLC code and the drive/motors/encoding you use.... so use it that way, get NC working on its own, then move to PLC with the MC function blocks, and you should be good to go.
+SquishyBrained Thanks for the feedback. Yeah, we've bought new Beckhoff hardware and I have been using their support as much as I can while at the same time trying not to become a nuisance to my Beckhoff applications engineer. Have learned a lot on my own, internet, and videos like these. Been through the TwinCAT training in Mississauga, ON. about a year ago but since it was so long ago, and they blow through those training sessions so fast, its difficult to retain even half of what is discussed. I wish Beckhoff would create a website with a forum where users can collaborate, much like what National Instruments has on their site. Again, thanks for the solid advice. I'll be sure to write it down and refer to it once I get started on the motion project. Thankfully, I found out last week that it's been pushed out a couple years, so at least now I have good time to figure things out and do it right.
+Don McKiness I agree on the forums and I've given them that feedback many times, but nothing yet. the closest we have is the LinkedIn group which is not bad but not really the right format, and no offical beckhoff people answer questions there.
Good afternoon! I just started following your videos for this specific topic and I find this message when I try to "Restart TwinCat system in Run Mode" while attempting to run the code. This is the message: AdsWarning: 4115 (0x1013, RTME: system clock setup fails. hint: On windows8 system and above execute win8settick.bat in TwinCAT\3.1......>>failed!. What do you think I should do? Thanks in advance!
Hey I want to ask, why there is no graphs in 'Real time usage' window and 'system latency' window @ 4:41 . I want to see latency of my system how can I enable them ??? My system at the moment doesn't have any PLC task , it is running only I/O idle task.
You might need to have a real task in there for it to show the graphs... if not, check on the next item down, for the task itself. I think there are graphs there as well. If you can't figure it out I'll replicate on my machine and send a screenshot.

Hola! IT guy here. We run Think & Do to drive our equipment. Trying to work with our engineering group to move to something more modern and supported so we can eliminate WinXP from our environment. Would TwinCat 3 be something we should be considering? Would the transition be particularly painful?
Is it possible to pick a custom made BMP or PNG background on an visualisation? I have these switches set up in a program but i would like to see them on my visual with an background of the room they ar placed in. i can do this with the simple tools of Beckhoff, rectangles en lines and stuff but I find this a bit boring and like they say, the eye also wants something. By the way, youre tutorials are the best.
I have question about Scan Cycles. Is there a way I could flag the ST program to only execute certain lines of code on the "n" scan cycle? I have just been running into a problem where I need to perform something every 4 scan cycles; while the rest of my code runs normally? Oh and thanks for these wonderful tutorials, they've been a great help!
+Faisal Gedi, There are 2 ways to do what you are talking about.... They both just suit different needs. The first would be to create a new program "next" to your main program, and put the slower running code in it. Then you can create a new PLC task, and set the scan time to 4x that of your regular program, and point to your new program with that task. The down side of this approach is that you won't have access to the same variables and IO across the different PLC tasks. You can solve this by having input and output variables in each task and linking them together, but that is more work unless you really need fine control. Often if you said you need to run something 10x as fast as your main program, but you can't run your main program at 10x due to CPU speed limitations, that would be the best approach, run the high speed task at say 250uS, while the main task was at 10ms for instance. The other approach would be to add some logic with a counter in there. You can get fancy with the "MOD" operator and use the scan count, like "IF MOD(ScanCount) = 0 THEN", but a more clear way would probably be to do a quick loop, almost like a For loop. You can't use a FOR loop because that all runs in one scan, but you can fake it and have it execute one step of the for loop each scan: if i > 4 Then i := 1; end_if if i = 1 then runcode(); else i := i + 1; end_if So, unless I did something silly there, it'll run the code every 4th cycle, only when i = 1. If you want to slow it down more, change the 4 to a larger number. There are probably more clever ways to do this, but it'll get the job done.
Hey SquishyBrained....its resourceful video....i m pretty new to plc and way very near to a beginner. i have been studying about plc for couple of days the thing is that can i use ladder diagrams in TwinCat 3 r its only for structured texts??
Hello, Did you compare Codesys3.5 vs twinCat? at first it looks very similary, is there any diferents betwin this two softwares? if soo what is beter or it is just question of preference?
I've not actually used Codesys, however, back in the TwinCat 2.x days, it was pretty obvious (and not really hidden) that the beckhoff IDE was a rebranded codesys product. The integration into visual studio may or may not be related to codesys, but the low level runtime stuff for sure still has ties to codesys... you see it in error messages once in a while. But essentially, if you had to program one or the other instead of your usual, you are 90% of the way there, they are incredibly simple. For that matter, if it is IEC61131-3, you are at least 75% there with any new PLC you get into, which is something I hoped to get across in episode 1. So, my preference is Twincat, but only because it is the one I used, and the Beckhoff sales and support has been great, and they are really leading the market with hardware out there, though that is another discussion. Have fun!
SquishyBrained i once think about this point，and there are some other company plc also based the codesys ，for example festo plc，they are really very similar. i also just have experience at twincat2
The two are very similar. What you use is going to end up basically determined by which hardware you are running on your system. - The actual End Hardware PLC - Not your PC. - Bottom line is if you can program with one you can program with the other.
Hello There I am having problem installing the Twincat, it's keep giving me "the installation of Microsoft Visual Studio 2013 Isolated Shell has failed. Setup will now exit". is something that is missing from my computer?
Hello,Your tutorials were of great help. I have a small question,How can i start scope and MAIN plc program together? That means, when i click the Login button , scope should also start at the same instant
Hurm. triggering the scope might be a paid feature of scope pro... not sure really. there should be some function blocks to talk to it. I think the "online connected status" is a hidden variable you can access, so you could set the scope up to trigger on that I'd guess. I'm not sure why a user logging in would be a good trigger though. sorry I can't be of more help on this one.
Hi really good video, when I am going to run the simulation I am getting an error saying 'symbolic mapping' needs to be disabled. Trying researching the issue but have come up with a fix
Yes, that is a pretty good option to talk with AB devices. Another choice is OPC-UA. The Beckhoff side can be a server or client. As for Ethernet/IP, Beckhoff can be a scanner or adapter (master / slave). The master is typically the one that connects to multiple devices, which is often the "higher level" device in the architecture.
Hi Evan, This is great! The video, clarity, Audio and your way of explaining is way better than most pros!! Anyways, after I download and tried to run that small program to test the TwinCAT 3, I am having a problem with the run-time - I am getting this error message - I am facing this stupid error when I try to activate the configuration first - "AdsWarning: 4120 (0x1018, RTIME:enter realtime mode fails: Intel VT-x extension not enabled (in BIOS)!)
+Tarique Islam OK. I Figured the problem out. Actually took help from the Beckhoff Tech Support. I email them on Saturday, and by Sunday (holiday!) I received their email back with a solution - I was to set the Visualization to Enabled in the BIOS of the Lenovo laptop - which they sent me with clear illustrated instruction.(The VT-x in the TwinCAT 3.1's error message , which I confused with the VT-100 Terminal setting, turned out to be that the Intel Processor need to be ENABLED for "Virtualization" - as the PLC Runtime is a Virtual (Software implemented) machine running inside Windows 7 running the Intel Processor of the Lenovo!
when i try to put it in runmode i get these errors, does someone know how to resolve these? tnx Error 26 7/02/2018 19:19:43 370 ms | 'TCRTIME' (200): start of real-time avoided by "KB4056894" Error 27 7/02/2018 19:19:43 371 ms | 'TwinCAT System' (10000): Sending ams command >> Init4\RTime: Start Interrupt: Ticker started >> AdsWarning: 4132 (0x1024, RTIME: incompatible software detected)
KB4056894 is likely that new spectre/meltdown patch for windows that broke twincat (and lots of other software). I think you can uninstall it... beckhoff has a descrpition of that problem out there somewhere and how to fix it.
has anyone ever tried to run TwinCAT 3 on Windows 10 Enterprise. I run into an error when I try to add a Standard PLC Project to the PLC tab after creating new TwinCAT project.
Welcome to twincat. My guess is that your best bet is to either check your virtualization settings in your BIOS, or set up a dedicated CPU to run twin cat on while you're working on your local computer
sometimes the context is everything, and in twin cat a shared core is something that windows in twin cat can both run on. But it much prefers to run on a dedicated core
SquishyBrained I found the issue.. I have multiple cores n I use an amd Ryzen cpu, so Windows can’t operate on a shared core with Twincat, so I had to isolate a core for twincat to run in real-time settings in my project and that was the fix... Thank you for your time, and your videos are great, they’re what my professor and my fellow classmates use for our industrial automation course..
SquishyBrained Minnesota State University, Mankato... your videos are pretty easy to follow and especially for newbies, so after he explains what we have to do, we just watch your videos to see being done practically and we can easily follow through.. especially with the fact that we can’t do in person classes again cuz of Covid.
Any chance with some help?? I am running windows through Parallels on my Mac and seeing this error. "Setting TwinCat in Run Mode on windows core(s) inside unknown (virtual machine) is not possible" Thanks Jacob
You are likely out of luck using that VM. I've used a VM in the past, but you have to have full virtualization support. On windows machines it requires Intel VT-X extensions turned on. If you have an old xp or win 7 maching you might be better off. I can't complain too much, being able to run at all on local hardware that is not an actual "PLC" is pretty nice.
Thanks for the reply, I tried everything and couldn't get it to work. My other laptop is running windows 10, but I'm getting the "Invalid system Id" error like @emit Jha above. My system Id is blank when I open the License tab.
Interesting. I saw duplicate system IDs once, but never a blank one. I'd try uninstall and reinstall just in case that works, and be sure you try a fresh version of twincat. Honestly, sometimes it might be better to roll back a version or two when you download it. They change it often, and sometimes they break stuff and don't realize it right away. As a software developer I can appreciate that it happens from time to time.
Hi, Is it possible to use this Tiwncat3 VB to link it with any modbus rtu slave controller/Device, so your labtop will be as master where you can have data from the slave and log it? it seems to me it is possible by adding new devices I/O.
You can do that in visual basic without twincat, since modbus RTU runs on a serial port. With that said, you can use TS6255 to get modbus working in twincat, but you'll need a serial port on the PLC or PC. If its a PC, you can use an EL6001. I imagine there is some modbus master out there you can just run and not even have to write any custom software, but I have not looked.
The serial port we can have rs-232 to USB converter to connect with my PC/Labtop, my target is to make my PC as Master. If there is any manual or reference for the mentioned TS6255 please guide, so I can set it up.
A absolutely awesome instructional video! Probably one of the best I have seen so thank you for putting in the effort!! A small questions is can TwinCAT run in VMWARE??? I currently run a number of Vendor based applications from Rockwell, Schneider etc and do tend to run in VM's as it seems they can 'clobber' each other when running in the same environment. I just was working through this episode and got the following error "Setting TwinCAT in Run mode in windows core(s) in VMWare is not possible. Activate solution using only isolated cores". Would prefer to run in VM if possible... Any ideas..... Thanks in advance and look forward to working through the rest!!
I'm not sure you can run the runtime in a VM... you might be able to if you dedicate 2 processors to the VM, and 1 of those 2 to twincat directly, which you can do somewhere in the 'system' tab in there (and reboot). I had no luck with that in the past though. I understand the need to run things like this in a VM. My main complaint is the stupid splash screen they put on at boot, which you can remove if you want to, but otherwise, it doesn't hose up the main PC too badly. if you want to install just twincat "Engineering" and not the runtime, you can target other systems and it ends up being a pretty lightweight system. You can run the "Engineering" side in a VM no problem, but you'll need some other dedicated hardware to target in that situation.
Thanks for the prompt reply! Worked through what you suggested and it happily runs now in VMWorkstation V12 running 2 CPU 2 Core with 1 dedicated too TwinCAT. Thanks again for getting back to me!!
Hey SquishyBrained I'm finding this series the best I've seen so far. I'm an amateur programmer and I'm trying to control my telescope dome using PLC through TwinCAT 3 software. Could you please elaborate on the use of C++? Will I be able to write my PLC code in C++?
That sounds like a fun project. I'm glad you are enjoying the videos. I've honestly not used the C++ integration, as most of our customers would prefer a more standard language in the automation world (Or in other words a language more technicians understand, some companies even force ladder logic). C++ does have its benefits, but to me, for automation, that is mostly in code reuse and advanced algorithms that I typically do not get that involved in. I've been wanting to play with OpenCV along side twincat for a while, but I have not. I imagine there are all sorts of good scientific libraries you could use with telescope to help out, but you can also run those on a higher level PC and simply send control commands to twincat using ADS.dll, PyADS, or other methods. There is a webinar from Beckhoff that should cover the basics: www.beckhoff.com/english.asp?support/webinars.htm I've just never really found a use for it, and Beckhoff makes you pay extra for it, and I believe you need visual studio professional which is another $500 or so, so I just don't bother with it right now.
SquishyBrained Yeah in order to communicate with the telescope, I will be using a pre coded ASCOM driver that exists currently which is coded in C# And I did have a look at the webinars too as you said but did not really find a connection between the C++ and the PLC modules. I have the visual studio professional 2010 as well as 2012 and have been using the 2010 version. So I think I will try going ahead by coding my PLC in ST language as you have shown. Could you please also upload a few videos on interfacing the PLCs with various outside world devices/sensors or maybe RS 232 etc? Since I'm pretty sure everyone will be using a PLC for automation where they would be interfacing the same with some kind of external sensors or so. Thank You!
Nachiket Paranjape Hey... I will try to do some other videos at some point... typically we use EtherCAT as much as possible for motor drives, hard IO, etc. I've not used an RS232 setup, but it is not too difficult once you understand the code in my examples... there are function blocks provided by Beckhoff for most of those things. If you have your program already running in C#, you might want to look at ADS.dll from beckhoff. It is a bit convoluted, but they have good examples out there to get and set variables with .NET (VB and C#). We use this stuff extensively, but the code we use is proprietary and I can't really share it, but the interface is nice. Essentially, it lets you read any variable in PLC memory, or Write it. So, you can assign coordinates to your telescope and have the PLC execute the trajectory, etc, or do something as simple as having a button in C# kick off your star tracking state machine or whatever else you are getting into.
SquishyBrained Do you reckon using a state machine for the dome control of the telescope? Does a PLC always have to run a a finite state machine? Does the ST code keep running even if I do not put a for loop? I need some checks to happen in every state of the machine. I have now downloaded the function blocks and am trying to understand each. The one for database connection seems convoluted. Please do upload some more videos on function blocks and hardware if possible. Thanks.
Nachiket Paranjape I doubt I'll have time to make any new videos real soon... I'm on a busy project at work and have a different side project starting at home... Message me if you have questions. The database FB is pretty nice to have, as most PLC vendors don't have one, but it is pretty cumbersome. If you have a 'VB' side of your setup, I'd try to keep the database access on that side of the software and keep the PLC doing realtime things. As for the state machine, using a state machine is just what I've landed on as a good practice in PLC. You essentially end up there anyway, but with a ton of conditions like "if this and not that and mode is automatic and power is applied and the user clicks this button". It gets messy, so keeping track of the machine state via a state machine is usually ideal. With that said, every machine I've programmed also has many lines of "out of state" code that run all the time. The PLC will run a lot like most microcontrollers, you just don't have to put a 'while' loop around the entire code, since it already exists. I recommend avoiding while loops as much as possible, especially at first. A 'for' loop is only needed if you need to iterate through a bunch of items and process or do math to each one of them.
When I try to Activate my Configuration I get the following error: Setting TwinCAT in Run Mode with KB4056894 is not possible it asks me to uninstall this, but I can't find it on my computer. Any ideas?
Yea, that is the new spectre/meltdown windows patch that broke all sorts of lower level software. There is a way to disable the patch with a registry setting I believe, or you can try to uninstall that update. There should be a guide on how to make twincat work from Beckhoff, I think they are still working on a final solution.
Hi dear, your tutorial it's very clear and way better than Beckhoff help, thanks for your time to have done this. I've been following the tutorial, and I'm stuck in a very small step, when I want to run the code, I have to log in, but in my twincat, that option is grey, so I can't do it, how can I solve it? I'm just in this part of the tutorial, so I can not get what language it is, it's C? What are the options to change in to other language? Thanks!
I got an issue while it was doing the activate configuration. I got a second message "real-time start diagnostic" description: Intel VT-x is not supported or not enabled in the bios. Solution:Check your CPU type and BIOS settings for VT-x/Intel Virtualization Technology. or Activate a solution using only isolated cores. No sure what that means.
I think there are some other comments that talk about this. You need an intel CPU with VT-x enabled in the bios. You can dedicate a CPU to the runtime, but last I checked it still won't work on AMD cpus.
The trick of how TwinCAT can run realtime on a regular PC with windows on it no less, is through VT-x. Normally you can't run any process reatime on windows, it's just not possible. So what TwinCAT does, is it bypasses windows entirely using VT-x and runs it's realtime code natively, without the opsys in the way. VT-x is Intel's hardware virtualization feature, normally used to run virtual machines, without having to emulate through host system. Basically TwinCAT ends up running parallel to windows, instead of slave to it. It's usually disabled by default, you have to enable it in BIOS. I'm not sure if TwinCAT can run on AMD processors, maybe? Never tried to.
I'm doing a project Object oriented programing with Twincat3, which i have to submit before chrismass. I guess that means we're stuck we are stuck until chrismass you and I.:D
when i am trying to run PLC code it is giving me this error "intel vt-x is not supported or not enabled in the bios error in plc" . Can you please tell me how to fix it ?????
+Muhammad Rehan Aslam I think some other comments address this, but essentially you need to enable vt-x in the pc bios. It may show as "virtualization settings". I'm not sure if it is an Intel only thing. Also, "home" versions of Windows are not supported and can cause the error also.

Hello I tried to download Twincat 3 , but it seems to be only available at 64 bits OS.. Well , I am looking for a 32 bit version, but in the meanwhile if you know a link to download the 32X i will be greatfull. Let me ask you another question. I noticed that there is a CNC module to the twincat 2 ..Is there any kind of G-Code interpreter to input the coordinates in the system, and can i output the step and position signals via Can bus and operate 3 axis?
There is a 32 bit version, if you cant find it pm me and I'll find the link. As far as cnc, there is an interpreter. I've not used step and direction, but can open works well, basically you can use any commom motor or interface since the "nc" system abstracts the actual hardware.
I found the 32 bit version. My biggest problem now is to figure a way to connect 3 servo-drive motors to my computer.. and send signals to it from a g-code source software. The motors are synchronous DC Motors, and it has the drives and encoders integrated in the housing. It is from Danfoss , ISD 410, they comunnicate via Can-Bus and , according to the documentation I found on the Web, they are IEC61131-3 standard. Well, I am trying to learn as much as I can to try and figure out a way o solve this by myself, but although I have learned a lot of things related, it still lacks experience to put all this knowledge togheter and connect this motors in a proper way.. I have "sort of" a dead line to finish this build , I have finished the whole mechanical structure .. I have seen some USB- can-bus Inverters.. I wonder if I can get the signals from my PC out of the serial port and have only this inverter as an interface between the drives and the PC. Can bus is only a protocol to exchange signals in a bus,so I see no problem in having PWM, or step and direction , (whatever signal that talk to the drive and control the motor) encapsulated by a Can protocol and be sent straight to the drives without these breackout boards or similars.. well basically I need to keep it as unexpansive as possible . Thanks for answering ..
when I click on "activate configuration" & when "restart in run mode" message appears to me & I click on"Yes", the laptop freezes & won't work until I force it to shut down. I tried it 3 times & the same thing happens each time.
Odd. Do you have any real hardware in the mix? Typically freezes like that are hardware related, often if the network card is not setup properly for EtherCAT. Also, try activating a fresh project with nothing in it but a single semicolon and see if that lets it run. Otherwise, hit up beckhoff support.
Hey again! No I don't have any real hardware for now because I'm just learning on the software in general & structured text specifically. I tried activating a new project with only a semicolon but it did the same thing. It froze & I had to force shutdown the laptop again .
Hy Hasan Atieh! What operating system do you use? I was having such a problem with the 1803 Update. Since I've been using 1703 since then, TwinCAT has been working perfectly. (Windows 10 Pro)
im having problems getting running on and amd a10 processor on windows 7 ultimate x64. i have virtualization turned on in the bios. when i go to activate configuration i get 'intel cpu is required to run TwinCat on windows core under 64 bit' with a solution of Activate a solution using only isolated cores. when i go into the real time tab i have 4 available cpus and no isolated. anyone know how i can get this running? i wouldnt care if i had to run it in 32 bit i just cant find how to do that either.
So... I tried this recently on my AMD cpu on Windows 7, and it is a No-Go. I have a 64 bit system as well. I'm not sure if 32 bit will work, but honestly your best bet is to find an intel box, an old laptop or something. If you network to it, you can still write code on your main AMD box and just run it on the other machine. I wasn't aware of this limitation until recently on AMD or I would have mentioned it in the videos.
I had the same problem running an Intel 4core processor... In the real time tab there is an option "Set on target" I used that option to downgrade my PC to 3 Windows processors and 1 isolated and it worked... Idk if you can do that with an AMD processor
Hey SquishyBrained, your videos are really very helpful, thanq so very much! I've installed Twincat3 on Windows 7 with Visual Studio 2013. But when I tried to get the 7 days trial license it says 'Invalid system ID', which shows all zeros. And the buttons on the quick access toolbar are not working either..Help me out guys¿ thanks!
Hello Dear, I have Windows8.1 on 64bit, Virtualization is active; but when I press Activate Configuration, it shows "Restart Twincat in Run Mode"; then I got error: Init4\RTime: Start Interrupt: Ticker started>>AdsWarning:4115 (0x1013, RTIME: system clock setup fails. Hint: On Windows8 system execute win8settick.bat in TwinCAT\3.1\System as administrator and reboot.) Can you help me please?
***** I've not used it on Win 8. What is strange is that it seems to be a warning, not an error... can you continue on after the warning? I'd consider a Windows XP or Windows 7 Virtual Machine with virtualbox. Also make sure virus scanners are off and your VT-x setting is set in the bios.
***** Sorry, I would guess it should, but I've not used it on 8.1 or 10, and I don't think anyone else at my company has either. We are all on Win7. You could try an XP virtual machine.
Hello First off, very informative and well explained videos! But I still have some questions. I am really new in the all programming and I have issues in setting TwinCAT up on my PC. I downloaded TwinCAT 3, installed it, now I have it inside my Visual Studio 2013 Ultimate, but when I write the line of code and press Activate Configuration, then, after I press OK on "Restart TwinCAT system in run mode," error messages (screenshot) pop up. s11.postimg.org/vpyxk0vnn/Twin_CAT3_error.jpg Is the problem in my Visual Studio version or in my PC performance? Thanks for the videos and looking forward to your feedback
The vt error is related to virtual technology. You can enable it in the bios. Our new guy got this problem and was not able to resolve it on that computer even after setting it on in the bios. I don't think the problem is your visual studio version. Sorry I dont have more help, but thanks for the positive feedback.
SquishyBrained Thanks for the quick reply. ok, I checked and it turns out that my processor doesn't have this capability (virtual technology). Does that mean now, that I can't run TwinCat at all?
Kristofer Ott Sutt sadly it means you can't execute on your local machine. What I did in the past was run vmware player and run it in there, but I think even that may need virtualization. I'm not sure why this is a requirement now since we used to run on all sorts of machines.... Do you have an older machine you can try on? Maybe try twincat 2, or use a 32 bit virtual machine and try that...
Joaquin Arancibia, There should be a lot of info about it online. Be sure you check the VT-x virtualization settings in your computer's bios. Flip it on if it is off. Alternatively you can grab vmware player or virtual box and bring up a Windows XP or Windows 7 Virtual machine. Install and run there. I did that way back when and it worked. Additionally, it does not play well with virus scanners sometimes, so try exiting those if you have any running.
I think ST is a better language all over the wold, but probably in India as well, I've never been there. All the languages run the same once written, its all about maintainability and ease of use, where I prefer ST.
Sorry for delay, it was marked as spam... I've not seen that one. The problem is it didn't generate a system ID from your hardware. Maybe it is a VM? I dunno, should work still. Try reinstalling, or worst case use a different computer :-/
Hi, thanks for great tutorial. I was following the steps and got the following errors (both on win10 & win8.1), any idea what can I do to resolve it? www.hemelix.com/twincat/public/twincat3_1_errorwin10.png www.hemelix.com/twincat/public/twincat3_1_errorwin81.png Edit 28/1/2016: With windows 10 it works after following these steps A. BIOS security settings visualization should be enabled B. C:\TwinCAT\3.1\System\win8settick.bat should executed as adminstrator C. Reboot
+Mahbub Rahman I'm not on windows 8.1 or 10, but people I know use it. There is a batch file you can run to fix the 8.1 problem, the path to the batch file is included in the error message, be sure to run it as adminitrator. For the other problem, you have to enable the VT-x extensions in the bios for virtualization. It allows the Beckhoff realtime kernel to have lower level access to the CPU that would otherwise be possible. Google around for it, there are lots of threads about it on the linkedin twincat forum, but basically enabling that setting in your pc bios will fix it 95% of the time.
+Sergio Zermeno Is it Windows 10 Home edition? If so, I recently found out that Windows 10 Home does not allow a vitalization option, so VT-x is not supported and you are out of luck. So, assuming you have VT-x working and enabled, and a pro version of windows 10, install twincat as administrator it should work from my experience. If not, honestly the best way to get going is to fire up a virtualbox VM or find an older PC somewhere and target that. You can develop on your Windows 10 box for sure, just not run the runtime code until the problem is figured out.
+Evan Jensen Thank you for replying. I am on Windows 10 pro. I have ensured that the VT- X is enabled. I am running it on the new Dell XPS. I I have gone to the batch file and set it with administration setting but still same problem. I will have to try using a Win 7 PC
+Sergio Zermeno Very odd. I just upgraded to 10 on my work computer. I'll try to get it going, as I've run just fine on this box in Win 7. I can't do it today, but sometime soon I'll try to do it and come back to this comment.
Thanks for these wonderful tutorials. Even after 5 years, your tutorials are great and easy to follow. There aren't many Twincat tutorials out there.
Thank you so much for going through the basics. I am new to structured text (been doing ladder logic for years) and I started watching another series of ST videos and the gentleman giving the tutorials, while extremely knowledgeable, went right into pretty advanced stuff I cannot grasp at this point. Your vids are EXACTLY what I am looking for. THANKS!!
Your tutorials rock. I love upgrading my experience from AB PLC and TC2 to TC3. Thank you!
nice voice which don't make me tired listening to you. thx from dk.
You are some kind of legend for doing this. If these videos turn out to be as helpful as i suspect they are going to be i will send you beer. Much beer.
haha, thanks. I had to learn the hard way and an intro like this would have helped me a lot.

thank you bro :) greetings from Turkey

Thanks!!! Right at my birthday too. Very happy for the support.
congratulations from Brazil.
Thank you so much for this video. You make this complex product easy to understand.
+Joseph Donohue Thanks. No problem. I found it difficult at first until I learned it, I had a decent introduction from a co-worker, but nothing I could find online was worth a damn, hence this video series. I'm glad you enjoyed it.
Thanks for the tutorial. I've been looking for something like this on RUclips or elsewhere on the net. I'm just getting my feet wet with TwinCAT 3 and the Beckhoff platform. In the process of commissioning a machine right now using Beckhoff hardware. The program itself is pretty basic with using some basic discrete and analog I/O. Not too bad. The next project will be a lot more complex (I think?) as it will utilize two servo motors that will operate in strict velocity mode and also used for positional control. I'm not looking forward to the learning curve so I'm hoping it's not going to be as bad as I think. Hope you've created a video tutorial on motion control. Thanks again.
+Don McKiness Thanks. No motion control videos yet, but that will be my topic if I get around to doing more videos. I don't think it'll happen any time real soon though.
Here are some hints:
If you buy new beckhoff hardware, use their support.
If running servos, dish out the small amount of cash to get the beckhoff NC (PTP) System.
Velocity control is pretty easy... You'll want use the MC function blocks... MC Drive and MC2... they are pretty well documented, but may seem overly complicated at first. They are not that bad. You'll need MC_Power to get the drive moving from PLC control.
If you use NC, you can use the NC system from the IO section of the project without even needing to write PLC code. With that you can get a lot of things working and get your encoder scaled properly and stuff like that. Once all that is working, move to PLC code at that point so you don't bite off a big chunk all at once. The point of the NC system is to be an abstraction layer between the PLC code and the drive/motors/encoding you use.... so use it that way, get NC working on its own, then move to PLC with the MC function blocks, and you should be good to go.
+SquishyBrained Thanks for the feedback. Yeah, we've bought new Beckhoff hardware and I have been using their support as much as I can while at the same time trying not to become a nuisance to my Beckhoff applications engineer. Have learned a lot on my own, internet, and videos like these. Been through the TwinCAT training in Mississauga, ON. about a year ago but since it was so long ago, and they blow through those training sessions so fast, its difficult to retain even half of what is discussed. I wish Beckhoff would create a website with a forum where users can collaborate, much like what National Instruments has on their site. Again, thanks for the solid advice. I'll be sure to write it down and refer to it once I get started on the motion project. Thankfully, I found out last week that it's been pushed out a couple years, so at least now I have good time to figure things out and do it right.
+Don McKiness I agree on the forums and I've given them that feedback many times, but nothing yet. the closest we have is the LinkedIn group which is not bad but not really the right format, and no offical beckhoff people answer questions there.
Good afternoon! I just started following your videos for this specific topic and I find this message when I try to "Restart TwinCat system in Run Mode" while attempting to run the code. This is the message: AdsWarning: 4115 (0x1013, RTME: system clock setup fails. hint: On windows8 system and above execute win8settick.bat in TwinCAT\3.1......>>failed!.

Hey I want to ask, why there is no graphs in 'Real time usage' window and 'system latency' window @ 4:41 . I want to see latency of my system how can I enable them ??? My system at the moment doesn't have any PLC task , it is running only I/O idle task.
You might need to have a real task in there for it to show the graphs... if not, check on the next item down, for the task itself. I think there are graphs there as well. If you can't figure it out I'll replicate on my machine and send a screenshot.

Hola! IT guy here. We run Think & Do to drive our equipment. Trying to work with our engineering group to move to something more modern and supported so we can eliminate WinXP from our environment. Would TwinCat 3 be something we should be considering? Would the transition be particularly painful?
Is it possible to pick a custom made BMP or PNG background on an visualisation? I have these switches set up in a program but i would like to see them on my visual with an background of the room they ar placed in. i can do this with the simple tools of Beckhoff, rectangles en lines and stuff but I find this a bit boring and like they say, the eye also wants something.
By the way, youre tutorials are the best.
Yes, you can drop a photo frame in and set it as a background. Not sure how these days but I think it is possible
@@SquishyBrained I found it, just create a imagepool and you can drop anything in there. Once you know it, its verry simple.
I could not find that Activate Configuration button in my software. Where can I find that?
I have question about Scan Cycles. Is there a way I could flag the ST program to only execute certain lines of code on the "n" scan cycle? I have just been running into a problem where I need to perform something every 4 scan cycles; while the rest of my code runs normally?
Oh and thanks for these wonderful tutorials, they've been a great help!
+Faisal Gedi, There are 2 ways to do what you are talking about.... They both just suit different needs. The first would be to create a new program "next" to your main program, and put the slower running code in it. Then you can create a new PLC task, and set the scan time to 4x that of your regular program, and point to your new program with that task. The down side of this approach is that you won't have access to the same variables and IO across the different PLC tasks. You can solve this by having input and output variables in each task and linking them together, but that is more work unless you really need fine control. Often if you said you need to run something 10x as fast as your main program, but you can't run your main program at 10x due to CPU speed limitations, that would be the best approach, run the high speed task at say 250uS, while the main task was at 10ms for instance.
The other approach would be to add some logic with a counter in there. You can get fancy with the "MOD" operator and use the scan count, like "IF MOD(ScanCount) = 0 THEN", but a more clear way would probably be to do a quick loop, almost like a For loop. You can't use a FOR loop because that all runs in one scan, but you can fake it and have it execute one step of the for loop each scan:
if i > 4 Then
i := 1;
end_if
if i = 1 then
runcode();
else
i := i + 1;
end_if
So, unless I did something silly there, it'll run the code every 4th cycle, only when i = 1. If you want to slow it down more, change the 4 to a larger number. There are probably more clever ways to do this, but it'll get the job done.
Hey SquishyBrained....its resourceful video....i m pretty new to plc and way very near to a beginner. i have been studying about plc for couple of days the thing is that can i use ladder diagrams in TwinCat 3 r its only for structured texts??
Bhaskar Charan it'll do all the iec61131-3 languages.
Hello,
Did you compare Codesys3.5 vs twinCat?
at first it looks very similary, is there any diferents betwin this two softwares?
if soo what is beter or it is just question of preference?
I've not actually used Codesys, however, back in the TwinCat 2.x days, it was pretty obvious (and not really hidden) that the beckhoff IDE was a rebranded codesys product. The integration into visual studio may or may not be related to codesys, but the low level runtime stuff for sure still has ties to codesys... you see it in error messages once in a while.
But essentially, if you had to program one or the other instead of your usual, you are 90% of the way there, they are incredibly simple. For that matter, if it is IEC61131-3, you are at least 75% there with any new PLC you get into, which is something I hoped to get across in episode 1.
So, my preference is Twincat, but only because it is the one I used, and the Beckhoff sales and support has been great, and they are really leading the market with hardware out there, though that is another discussion.
Have fun!
SquishyBrained i once think about this point，and there are some other company plc also based the codesys ，for example festo plc，they are really very similar. i also just have experience at twincat2
The two are very similar. What you use is going to end up basically determined by which hardware you are running on your system. - The actual End Hardware PLC - Not your PC. - Bottom line is if you can program with one you can program with the other.
Hello There I am having problem installing the Twincat, it's keep giving me "the installation of Microsoft Visual Studio 2013 Isolated Shell has failed. Setup will now exit". is something that is missing from my computer?
Hello,Your tutorials were of great help. I have a small question,How can i start scope and MAIN plc program together? That means, when i click the Login button , scope should also start at the same instant
Hurm. triggering the scope might be a paid feature of scope pro... not sure really. there should be some function blocks to talk to it. I think the "online connected status" is a hidden variable you can access, so you could set the scope up to trigger on that I'd guess. I'm not sure why a user logging in would be a good trigger though. sorry I can't be of more help on this one.
Hi really good video, when I am going to run the simulation I am getting an error saying 'symbolic mapping' needs to be disabled. Trying researching the issue but have come up with a fix
Is it possible to control Allen Bradley drives from the Beckhoff system using EthernetIP?
Yes, that is a pretty good option to talk with AB devices. Another choice is OPC-UA. The Beckhoff side can be a server or client. As for Ethernet/IP, Beckhoff can be a scanner or adapter (master / slave). The master is typically the one that connects to multiple devices, which is often the "higher level" device in the architecture.
Great job!
Hi Evan,
This is great! The video, clarity, Audio and your way of explaining is way better than most pros!!
Anyways, after I download and tried to run that small program to test the TwinCAT 3, I am having a problem with the run-time - I am getting this error message - I am facing this stupid error when I try to activate the configuration first -

OK. I Figured the problem out. Actually took help from the Beckhoff Tech Support. I email them on Saturday, and by Sunday (holiday!) I received their email back with a solution - I was to set the Visualization to Enabled in the BIOS of the Lenovo laptop - which they sent me with clear illustrated instruction.(The VT-x in the TwinCAT 3.1's error message , which I confused with the VT-100 Terminal setting, turned out to be that the Intel Processor need to be ENABLED for "Virtualization" - as the PLC Runtime is a Virtual (Software implemented) machine running inside Windows 7 running the Intel Processor of the Lenovo!

SquishyBrained tnx, i ended up uninstalling the last update of Windows (from january). Now it seems to work poperly.
has anyone ever tried to run TwinCAT 3 on Windows 10 Enterprise. I run into an error when I try to add a Standard PLC Project to the PLC tab after creating new TwinCAT project.
im literally stuck on this error
Ads Error: 4139 (0x102b, TIME: start of shared core is denied!)
Welcome to twincat. My guess is that your best bet is to either check your virtualization settings in your BIOS, or set up a dedicated CPU to run twin cat on while you're working on your local computer
sometimes the context is everything, and in twin cat a shared core is something that windows in twin cat can both run on. But it much prefers to run on a dedicated core
SquishyBrained I found the issue.. I have multiple cores n I use an amd Ryzen cpu, so Windows can’t operate on a shared core with Twincat, so I had to isolate a core for twincat to run in real-time settings in my project and that was the fix...
Thank you for your time, and your videos are great, they’re what my professor and my fellow classmates use for our industrial automation course..
Excellent! Which university? Just curious
SquishyBrained Minnesota State University, Mankato... your videos are pretty easy to follow and especially for newbies, so after he explains what we have to do, we just watch your videos to see being done practically and we can easily follow through.. especially with the fact that we can’t do in person classes again cuz of Covid.
Any chance with some help??
I am running windows through Parallels on my Mac and seeing this error.
"Setting TwinCat in Run Mode on windows core(s) inside unknown (virtual machine) is not possible"
Thanks
Jacob
You are likely out of luck using that VM. I've used a VM in the past, but you have to have full virtualization support. On windows machines it requires Intel VT-X extensions turned on.
If you have an old xp or win 7 maching you might be better off. I can't complain too much, being able to run at all on local hardware that is not an actual "PLC" is pretty nice.
Thanks for the reply, I tried everything and couldn't get it to work. My other laptop is running windows 10, but I'm getting the "Invalid system Id" error like @emit Jha above. My system Id is blank when I open the License tab.
Interesting. I saw duplicate system IDs once, but never a blank one. I'd try uninstall and reinstall just in case that works, and be sure you try a fresh version of twincat. Honestly, sometimes it might be better to roll back a version or two when you download it. They change it often, and sometimes they break stuff and don't realize it right away. As a software developer I can appreciate that it happens from time to time.
Sorry, i have problem, can you help me?
thank you
Brilliant!!!!! Thanks!!!!
Hi, Is it possible to use this Tiwncat3 VB to link it with any modbus rtu slave controller/Device, so your labtop will be as master where you can have data from the slave and log it? it seems to me it is possible by adding new devices I/O.
You can do that in visual basic without twincat, since modbus RTU runs on a serial port. With that said, you can use TS6255 to get modbus working in twincat, but you'll need a serial port on the PLC or PC. If its a PC, you can use an EL6001. I imagine there is some modbus master out there you can just run and not even have to write any custom software, but I have not looked.
The serial port we can have rs-232 to USB converter to connect with my PC/Labtop, my target is to make my PC as Master. If there is any manual or reference for the mentioned TS6255 please guide, so I can set it up.
Fardan Fardann I think Beckhoff has an example out there. Luckily the virtual serial poets are a bit easier to work with.
A absolutely awesome instructional video! Probably one of the best I have seen so thank you for putting in the effort!! A small questions is can TwinCAT run in VMWARE??? I currently run a number of Vendor based applications from Rockwell, Schneider etc and do tend to run in VM's as it seems they can 'clobber' each other when running in the same environment. I just was working through this episode and got the following error "Setting TwinCAT in Run mode in windows core(s) in VMWare is not possible. Activate solution using only isolated cores". Would prefer to run in VM if possible... Any ideas..... Thanks in advance and look forward to working through the rest!!
I'm not sure you can run the runtime in a VM... you might be able to if you dedicate 2 processors to the VM, and 1 of those 2 to twincat directly, which you can do somewhere in the 'system' tab in there (and reboot). I had no luck with that in the past though. I understand the need to run things like this in a VM. My main complaint is the stupid splash screen they put on at boot, which you can remove if you want to, but otherwise, it doesn't hose up the main PC too badly. if you want to install just twincat "Engineering" and not the runtime, you can target other systems and it ends up being a pretty lightweight system. You can run the "Engineering" side in a VM no problem, but you'll need some other dedicated hardware to target in that situation.
Thanks for the prompt reply! Worked through what you suggested and it happily runs now in VMWorkstation V12 running 2 CPU 2 Core with 1 dedicated too TwinCAT. Thanks again for getting back to me!!
@@pauldonald7861 excellent. Good to know. I wonder if that works on amd processors...? Is yours AMD or Intel?
@@SquishyBrained This one is Intel!! I will run the same VM up on a AMD laptop I have somewhere and let you know !
Hey SquishyBrained I'm finding this series the best I've seen so far.
I'm an amateur programmer and I'm trying to control my telescope dome using PLC through TwinCAT 3 software.
Could you please elaborate on the use of C++? Will I be able to write my PLC code in C++?
That sounds like a fun project. I'm glad you are enjoying the videos.
I've honestly not used the C++ integration, as most of our customers would prefer a more standard language in the automation world (Or in other words a language more technicians understand, some companies even force ladder logic). C++ does have its benefits, but to me, for automation, that is mostly in code reuse and advanced algorithms that I typically do not get that involved in.
I've been wanting to play with OpenCV along side twincat for a while, but I have not. I imagine there are all sorts of good scientific libraries you could use with telescope to help out, but you can also run those on a higher level PC and simply send control commands to twincat using ADS.dll, PyADS, or other methods.
There is a webinar from Beckhoff that should cover the basics:
www.beckhoff.com/english.asp?support/webinars.htm
I've just never really found a use for it, and Beckhoff makes you pay extra for it, and I believe you need visual studio professional which is another $500 or so, so I just don't bother with it right now.
SquishyBrained Yeah in order to communicate with the telescope, I will be using a pre coded ASCOM driver that exists currently which is coded in C#
And I did have a look at the webinars too as you said but did not really find a connection between the C++ and the PLC modules. I have the visual studio professional 2010 as well as 2012 and have been using the 2010 version.
So I think I will try going ahead by coding my PLC in ST language as you have shown. Could you please also upload a few videos on interfacing the PLCs with various outside world devices/sensors or maybe RS 232 etc? Since I'm pretty sure everyone will be using a PLC for automation where they would be interfacing the same with some kind of external sensors or so.
Thank You!
Nachiket Paranjape Hey... I will try to do some other videos at some point... typically we use EtherCAT as much as possible for motor drives, hard IO, etc. I've not used an RS232 setup, but it is not too difficult once you understand the code in my examples... there are function blocks provided by Beckhoff for most of those things.
If you have your program already running in C#, you might want to look at ADS.dll from beckhoff. It is a bit convoluted, but they have good examples out there to get and set variables with .NET (VB and C#). We use this stuff extensively, but the code we use is proprietary and I can't really share it, but the interface is nice.
Essentially, it lets you read any variable in PLC memory, or Write it. So, you can assign coordinates to your telescope and have the PLC execute the trajectory, etc, or do something as simple as having a button in C# kick off your star tracking state machine or whatever else you are getting into.
SquishyBrained Do you reckon using a state machine for the dome control of the telescope? Does a PLC always have to run a a finite state machine? Does the ST code keep running even if I do not put a for loop? I need some checks to happen in every state of the machine.
I have now downloaded the function blocks and am trying to understand each. The one for database connection seems convoluted.
Please do upload some more videos on function blocks and hardware if possible.
Thanks.
Nachiket Paranjape I doubt I'll have time to make any new videos real soon... I'm on a busy project at work and have a different side project starting at home... Message me if you have questions. The database FB is pretty nice to have, as most PLC vendors don't have one, but it is pretty cumbersome. If you have a 'VB' side of your setup, I'd try to keep the database access on that side of the software and keep the PLC doing realtime things.
As for the state machine, using a state machine is just what I've landed on as a good practice in PLC. You essentially end up there anyway, but with a ton of conditions like "if this and not that and mode is automatic and power is applied and the user clicks this button". It gets messy, so keeping track of the machine state via a state machine is usually ideal. With that said, every machine I've programmed also has many lines of "out of state" code that run all the time.
The PLC will run a lot like most microcontrollers, you just don't have to put a 'while' loop around the entire code, since it already exists. I recommend avoiding while loops as much as possible, especially at first. A 'for' loop is only needed if you need to iterate through a bunch of items and process or do math to each one of them.
When I try to Activate my Configuration I get the following error: Setting TwinCAT in Run Mode with KB4056894 is not possible it asks me to uninstall this, but I can't find it on my computer. Any ideas?
Yea, that is the new spectre/meltdown windows patch that broke all sorts of lower level software. There is a way to disable the patch with a registry setting I believe, or you can try to uninstall that update. There should be a guide on how to make twincat work from Beckhoff, I think they are still working on a final solution.
Also, I read that the latest version of twincat did something related to that, so be sure you are on the latest as of like 2 weeks ago.
Hi dear, your tutorial it's very clear and way better than Beckhoff help, thanks for your time to have done this.
I've been following the tutorial, and I'm stuck in a very small step, when I want to run the code, I have to log in, but in my twincat, that option is grey, so I can't do it, how can I solve it?
I'm just in this part of the tutorial, so I can not get what language it is, it's C? What are the options to change in to other language?
Thanks!
Joaquin Arancibia I just got that it's the same problem that Kristofer Ott Sutt has, don't worry.
Thanks!
I like your tutorials! Thanks. Have you ever used the Beckhoff system with Simulink?
John Christensen I have not, but they do support it. they have some webinars on it I think on the beckhoff site.
I got an issue while it was doing the activate configuration. I got a second message "real-time start diagnostic" description: Intel VT-x is not supported or not enabled in the bios. Solution:Check your CPU type and BIOS settings for
VT-x/Intel Virtualization Technology.
or
Activate a solution using only isolated cores.
No sure what that means.
I think there are some other comments that talk about this. You need an intel CPU with VT-x enabled in the bios. You can dedicate a CPU to the runtime, but last I checked it still won't work on AMD cpus.
The trick of how TwinCAT can run realtime on a regular PC with windows on it no less, is through VT-x. Normally you can't run any process reatime on windows, it's just not possible. So what TwinCAT does, is it bypasses windows entirely using VT-x and runs it's realtime code natively, without the opsys in the way. VT-x is Intel's hardware virtualization feature, normally used to run virtual machines, without having to emulate through host system. Basically TwinCAT ends up running parallel to windows, instead of slave to it. It's usually disabled by default, you have to enable it in BIOS. I'm not sure if TwinCAT can run on AMD processors, maybe? Never tried to.
I'm doing a project Object oriented programing with Twincat3, which i have to submit before chrismass. I guess that means we're stuck we are stuck until chrismass you and I.:D

Let me ask you another question. I noticed that there is a CNC module to the twincat 2 ..Is there any kind of G-Code interpreter to input the coordinates in the system, and can i output the step and position signals via Can bus and operate 3 axis?
There is a 32 bit version, if you cant find it pm me and I'll find the link. As far as cnc, there is an interpreter. I've not used step and direction, but can open works well, basically you can use any commom motor or interface since the "nc" system abstracts the actual hardware.
Sorry, interpreter is g-code for any supported kinematic system. Includes delta, Cartesian, scara, even 6 axis serial
I found the 32 bit version. My biggest problem now is to figure a way to connect 3 servo-drive motors to my computer.. and send signals to it from a g-code source software. The motors are synchronous DC Motors, and it has the drives and encoders integrated in the housing. It is from Danfoss , ISD 410, they comunnicate via Can-Bus and , according to the documentation I found on the Web, they are IEC61131-3 standard.
Well, I am trying to learn as much as I can to try and figure out a way o solve this by myself, but although I have learned a lot of things related, it still lacks experience to put all this knowledge togheter and connect this motors in a proper way..
I have "sort of" a dead line to finish this build , I have finished the whole mechanical structure ..
I have seen some USB- can-bus Inverters.. I wonder if I can get the signals from my PC out of the serial port and have only this inverter as an interface between the drives and the PC. Can bus is only a protocol to exchange signals in a bus,so I see no problem in having PWM, or step and direction , (whatever signal that talk to the drive and control the motor) encapsulated by a Can protocol and be sent straight to the drives without these breackout boards or similars..
well basically I need to keep it as unexpansive as possible .
Thanks for answering ..
Thanks.
very good
when I click on "activate configuration" & when "restart in run mode" message appears to me & I click on"Yes", the laptop freezes & won't work until I force it to shut down. I tried it 3 times & the same thing happens each time.
Odd. Do you have any real hardware in the mix? Typically freezes like that are hardware related, often if the network card is not setup properly for EtherCAT. Also, try activating a fresh project with nothing in it but a single semicolon and see if that lets it run. Otherwise, hit up beckhoff support.
SquishyBrained Thanks I'm gonna try it!
Hey again! No I don't have any real hardware for now because I'm just learning on the software in general & structured text specifically. I tried activating a new project with only a semicolon but it did the same thing. It froze & I had to force shutdown the laptop again .
Hy Hasan Atieh! What operating system do you use? I was having such a problem with the 1803 Update. Since I've been using 1703 since then, TwinCAT has been working perfectly. (Windows 10 Pro)
Attila Becsi what is the 1703 and 1803 ı dont understand.???
im having problems getting running on and amd a10 processor on windows 7 ultimate x64. i have virtualization turned on in the bios. when i go to activate configuration i get 'intel cpu is required to run TwinCat on windows core under 64 bit' with a solution of Activate a solution using only isolated cores. when i go into the real time tab i have 4 available cpus and no isolated. anyone know how i can get this running? i wouldnt care if i had to run it in 32 bit i just cant find how to do that either.
So... I tried this recently on my AMD cpu on Windows 7, and it is a No-Go. I have a 64 bit system as well. I'm not sure if 32 bit will work, but honestly your best bet is to find an intel box, an old laptop or something. If you network to it, you can still write code on your main AMD box and just run it on the other machine. I wasn't aware of this limitation until recently on AMD or I would have mentioned it in the videos.
I had the same problem running an Intel 4core processor... In the real time tab there is an option "Set on target" I used that option to downgrade my PC to 3 Windows processors and 1 isolated and it worked... Idk if you can do that with an AMD processor
Hey SquishyBrained, your videos are really very helpful, thanq so very much!
I've installed Twincat3 on Windows 7 with Visual Studio 2013. But when I tried to get the 7 days trial license it says 'Invalid system ID', which shows all zeros. And the buttons on the quick access toolbar are not working either..Help me out guys¿ thanks!
did u figure it out?
Im also seeing this
Restart your PC and start twincat as Administrator
Restarted it a several times and I've logged in as an administrator..but it's still the same..
Amit Jha Right click on twinCat icon a click: Run as administrator. It worked for me. Otherwise i cant help you.
Hello Dear,
I have Windows8.1 on 64bit, Virtualization is active; but when I press Activate Configuration, it shows "Restart Twincat in Run Mode"; then I got error:
Init4\RTime: Start Interrupt: Ticker started>>AdsWarning:4115 (0x1013, RTIME: system clock setup fails.
Hint: On Windows8 system execute win8settick.bat in
TwinCAT\3.1\System as administrator and reboot.)
Can you help me please?
***** I've not used it on Win 8. What is strange is that it seems to be a warning, not an error... can you continue on after the warning?
I'd consider a Windows XP or Windows 7 Virtual Machine with virtualbox. Also make sure virus scanners are off and your VT-x setting is set in the bios.
SquishyBrained Thanks dear,
actually VT-x is enabled, and virus scanner is off,
so as I understand Twincat 3 doesn't work on Windows 8?
***** Sorry, I would guess it should, but I've not used it on 8.1 or 10, and I don't think anyone else at my company has either. We are all on Win7. You could try an XP virtual machine.
SquishyBrained runs fine on windows 10 - just needed to run the win8settick file as administrator and no problems afterword
Troy H Thanks. Glad it is working.
Niiiiice!
Best!
Hello
First off, very informative and well explained videos! But I still have some questions.
I am really new in the all programming and I have issues in setting TwinCAT up on my PC.
I downloaded TwinCAT 3, installed it, now I have it inside my Visual Studio 2013 Ultimate, but when I write the line of code and press Activate Configuration, then, after I press OK on "Restart TwinCAT system in run mode," error messages (screenshot) pop up.

Is the problem in my Visual Studio version or in my PC performance?
Thanks for the videos and looking forward to your feedback
The vt error is related to virtual technology. You can enable it in the bios. Our new guy got this problem and was not able to resolve it on that computer even after setting it on in the bios. I don't think the problem is your visual studio version. Sorry I dont have more help, but thanks for the positive feedback.
SquishyBrained
Thanks for the quick reply.
ok, I checked and it turns out that my processor doesn't have this capability (virtual technology). Does that mean now, that I can't run TwinCat at all?
Kristofer Ott Sutt sadly it means you can't execute on your local machine. What I did in the past was run vmware player and run it in there, but I think even that may need virtualization. I'm not sure why this is a requirement now since we used to run on all sorts of machines.... Do you have an older machine you can try on? Maybe try twincat 2, or use a 32 bit virtual machine and try that...
Kristofer Ott Sutt Did you solve this problem? Regards!
Joaquin Arancibia, There should be a lot of info about it online. Be sure you check the VT-x virtualization settings in your computer's bios. Flip it on if it is off. Alternatively you can grab vmware player or virtual box and bring up a Windows XP or Windows 7 Virtual machine. Install and run there. I did that way back when and it worked.
Additionally, it does not play well with virus scanners sometimes, so try exiting those if you have any running.
Is it better language than ladder logic in India?
I think ST is a better language all over the wold, but probably in India as well, I've never been there. All the languages run the same once written, its all about maintainability and ease of use, where I prefer ST.
LADDER IS MORE USER FRIENDLY LANGUAGE, SO IT USED THE MOST IN INDIA.
Great video man , but i keep getting this error message every time i ask for 7 days licence

any help ?!
Sorry for delay, it was marked as spam... I've not seen that one. The problem is it didn't generate a system ID from your hardware. Maybe it is a VM? I dunno, should work still. Try reinstalling, or worst case use a different computer :-/
Hi, thanks for great tutorial. I was following the steps and got the following errors (both on win10 & win8.1), any idea what can I do to resolve it?

Edit 28/1/2016: With windows 10 it works after following these steps
A. BIOS security settings visualization should be enabled
B. C:\TwinCAT\3.1\System\win8settick.bat should executed as adminstrator
C. Reboot
+Mahbub Rahman I'm not on windows 8.1 or 10, but people I know use it. There is a batch file you can run to fix the 8.1 problem, the path to the batch file is included in the error message, be sure to run it as adminitrator.
For the other problem, you have to enable the VT-x extensions in the bios for virtualization. It allows the Beckhoff realtime kernel to have lower level access to the CPU that would otherwise be possible. Google around for it, there are lots of threads about it on the linkedin twincat forum, but basically enabling that setting in your pc bios will fix it 95% of the time.
Were you able to solve the problem for Windows 10? I have the same issue and I have tried everything but it still doesn't work.
+Sergio Zermeno Is it Windows 10 Home edition? If so, I recently found out that Windows 10 Home does not allow a vitalization option, so VT-x is not supported and you are out of luck. So, assuming you have VT-x working and enabled, and a pro version of windows 10, install twincat as administrator it should work from my experience. If not, honestly the best way to get going is to fire up a virtualbox VM or find an older PC somewhere and target that. You can develop on your Windows 10 box for sure, just not run the runtime code until the problem is figured out.
+Evan Jensen Thank you for replying. I am on Windows 10 pro. I have ensured that the VT- X is enabled. I am running it on the new Dell XPS. I I have gone to the batch file and set it with administration setting but still same problem. I will have to try using a Win 7 PC
+Sergio Zermeno Very odd. I just upgraded to 10 on my work computer. I'll try to get it going, as I've run just fine on this box in Win 7. I can't do it today, but sometime soon I'll try to do it and come back to this comment.
