PLC programming using TwinCAT 3 - IO (Part 10/18)
HTML-код
- Опубликовано: 14 авг 2024
- When designing and building a control system you will eventually want the control system to actuate something, be it a relay, a motor, a pneumatic system or maybe a complete 6-axis robot. To get feedback of the actuation, sensors are needed. In this part we will cover how we communicate with the environment using inputs and outputs.

Jakob congratulates you again for your tutorials and this time I made a special mention of the EtherCAT Fieldbus animation.
Excellent work. thanks again for sharing your knowledge.
And thanks for the subtitles, help us to follow the tutorial for those of us who do not speak English perfectly.
Greetings from Venezuela.
It is GREAT as expected!!! 👏👏👏
You are indeed a part of my first TwinCAT project with your tutorials as my reference.
Thank you very much!
Hi Dennis! That makes me very happy to hear! Cheers.
You are really great!
You are expert in training as you are in PLCs :-)
I really enjoying the original stuff you came up with. the videos are well explained and the editing is extraordinary
Can wait for your next videos ...
Hey Moshe! I'm very happy that you find my tutorials useful!
A fantastic video again. Well done Jakob. Looking forward to the next episode.
wonderful exercise in TwinCat3 ! Thanks you Jakob.
Dear Jakob
Happy new year! It is again a very good tutorial part of your series.
Best regards
Rainer
Thanks Rainer!
Great intro to the hardware
Thank you for some great videos. Do you have one where you show how to install the ethercat master on you local plc? I do not have a controller yet, only some EL terminals connected to a EK1101.
Great overview!
Another fun video. Thank you :)
Thanks Vivek!
Thank you very much Jakob
You're welcome Rasoul!
Great tutorial Jakob, i'm learning so much from you.
I'm more experienced with Profinet & Ethernet/IP, but your explanation of Ethercat really clarifies the basics.
Do you know any other tutorials of Ethercat which targets the more advanced topics?
Thank you for your time and effort, really appreciated!
Hey Berry! I think your best bet is EtherCAT.org. They have lots of good information, once you've managed to register at their website. Happy that you find this course useful. If you want to support it, please consider becoming a RUclips member or Patron! Cheers!
Thank you for the great job you do to help beckhoff community users :)
Why dont we use any library from supplyer to do that kind of conversion ? Beckhoff seems to be so different than the others brand ^^
I work on it since few month, it quite impressive because you can do anything you want but that can be a big weakness too in my opinion
Thnak again for your job !
33:32 nWord1 and nWord2 😂 please don't get canclled lol
Another great video Jakob, congrats!
Related to CI/CD and code coupling, which approach do you consider to be better and why?
1. The inputs, from the sensor, are linked to an internal variable, like "aInputBytes" array on video.
2. The function block has an input variable, similar to "aInputBytes", and we pass the data from sensor as reference to the function block.
Thanks for this. The hardware side of TwinCAT is not my strong suit. This video gave me a better understanding of I/O. I especially liked your train analogy :D.
The train analogy was maybe a little basic, but making the animations was sure a lot of fun
@@JakobSagatowski haha I can imagine that creating those animations is a lot of work. You're becoming a power point expert!
@@RoRu87 I'll have to look into whether Microsoft has MVP's for PowerPoint
@@JakobSagatowski 😂
Made it this far 🤟
Hallo and Thanks for your new video!
It is not easy to have Hardware for every PLC Leaner,
May be you can try to make a combine with TE1111 :)!
Thanks! Yes TE1111 is definitely something worth to talk about!
I have tried both Beckhoff and IFM IO_Link master.
with IFM IO_Link master the device variables are shown by bytes and we need to combine the byte but with Beckhoff IO_Link master we can see the whole variable (e.g INT, SINT, UINT, etc.) and we can map it to our variable faster (in my opinion).
Great content jakob!!,,,,,I would love to see a video on how to use EtherCATSDO function block in TwinCAT..
Great video
Cześć Jakob:) As it is my first comment let me say I very much enjoy your tutorials - really great job. As of this part, I wonder why you didn't put these two bytes that comes from IO-Link into inputs of function block?
Hi Artur! Question I always ask myself is; do I need these two bytes anywhere else in the application, and decide whether that should be local in the function block or used as an input/reference into the function block. For the purpose of the demo, I only needed the two bytes in the FB.
I am new here. I had SCAN functionality greyed out, so it I had to click button "Restart Twincat config mode" and then it I was able use SCAN
Hey thank you for this great Video!
I have one question.
Didnt you forget to convert the Int distance to the range 5-200cm?
So (nDistance/4096*195)+5?
Or am I thinking wrong? :)
Thanks for these great videos Jakob. When do you think the full series of 18 parts will be available?
Hi! Trying to get them done as quickly as possible. Working on it every weekend, holiday and vacation. Support me on patreon (www.patreon.com/sagatowski ) if you like what I'm doing and want to have earlier access. Part 11 is already published for Patrons or RUclips members.
Hi Jakob. Thanks for the great series. Is the topology for EtherCat always Ring topology or can other topologies be used (star for example)? I ask because we have an SMC IO module for pneumatic valves that is failing and when the packets drop there it faults out our Estop modules. It would be nice that auxiliary modules not fault out something as important as a safety module but that seems to be the case with this topology.
Hi Jakob, really awesome job! It's really obvious that you have big passion for automation and your tutorials are so intersting to follow! You also make it hard for me to return to my usual work in TIA Portal after seeing how straightforward the Beckhoff development environment is 😂I am one of those software programmers who coincidentally got into PLCs so I'd rather use Visual Studio based IDE. I actually periodically talk about this in my company but they really don't want to move away from Siemens. The current hardware shortage might acutally be in favor for me. The fact that you could run Beckhoff program on any PC if you cannot get any other PLC in time is a big plus.
One question I'd have - is it possible to automate the Tag to IO assignment process with some custom scripting? I work with conveyor systems where we have around 600-700 photoelectric sensors and ~500 motors connected to one PLC via AS-interface to Profinet gateways so it would be quite timely to link every bit or byte for that amount of IO. For TIA we actually developed a way to convert excel documentation we get from our engineers straight into code that we just paste into TIA and mapping these signals take us like 10-15minutes. Do you think it would be possible to do something similar for TwinCat?
Hi Clooskey! I'm happy you find my tutorial useful. Yes, this is possible using the TwinCAT automation interface which I will talk about in a future episode of this course.
Thank you for another great video, I'm new to the hardware side so this is a helpful introduction. Thanks also for introducing us to your fixie by name (or is it a coaster-brake?) :) Question - where did you get your cool home hardware setup with a rail on a perspex stand? That looks practical and acceptable for the home.
It is indeed very practical and cheap! This is a home-made solution. A friend 3D printed the stands for me.
"I spent so much time doing this animation that I just have to show it once again" LOL
It's a nice animation! Pretty didatic. Which software did you use?
Tack för videorna.
You desk stand for din-rail is slick! Did you build it yourself? Would you mind sharing some links please.
Hello, I've been following your tutorials, it has been incredibly usefull. I have a question though, when you mentioned that ethercat needed to know the sync master time, when did you actually configure that value? or is it taken automatically from the slave que you linked the variables? Sorry if it a silly question.
Hi Javier! Not a silly question at all. Yes, the EtherCAT speed is taken automatically by the cycle-time of your task.
@@JakobSagatowski thank you very much! looking forward to your next releases! I had a little experience in siemens Ladder and in function block Niagara BMS programming, but this stuff is new to me. With your help I think I am getting up to speed a little bit at a time.

Fantastic tutorials. I appreciate it so much. Just please stop saying "this guy".
This is indeed the only thing i do not appreciate about it. 😅
Hi Jakob
How is going?
I started my first steps with an IPC C6920, but I have a problem. When add a new route this IPC appears with error: ads error 1796 (0x704). I can't use off configuration mode o run mode.
Also, the route appears with a padlock.
Have you some idea about this?
thanks Jak, could you please give us how to calibrate analog input and analog output 😇
Hey! I'll make sure to make a video about it in the future. Thanks for your feedback!
thanks, I (we) waite, I hope will be soon 😇☺ @@JakobSagatowski
