Great video. Thank you
Great video! Very straightforward explanation of how to use UDTs! I love seeing more people trying to help others unlock the power of well designed FBs!
Glad you enjoyed it Jason!
Very helpful video
Thanks a lot Hans
Great video! Send to my team members! Look forward for the advance one or the safety one!
Thanks Candia, appreciate the support!
this is very advance programming , it 's very organize because he's using UDT,,god bless sir.
Thanks Sir very very nice video upload thanks 👍👍👍👍👍
Very good video 💯❤ your teaching way are so deferent. Thank you
How is it different? Would be nice to know 👍🏻
Nice, pls make video on report generation
Thanks a lot for this great video. I have just one question: what is the word swapping in Siemens?
It’s not word swapping, it’s byte swapping - within a word. A word has 2 bytes - 0 and 1. You just swap those.
Very well explained.... Great work Patron ... Keep it up .... Could you please check for ATV0320 drive profibus communication with Siemens plc.
Thanks, sorry no experience with ATV0320
HI ,
There is no TELEGRAM option in my added drive properties 🤔
can you guide me ?
thanks in advance
Which drive did you add? Which plc are you using?
Your courses are amazing. Are you planning to make more advanced new courses on your website?
Yes I am working on a smaller course about advanced structuring. Thanks for your support!
good
Hello hans. Do you also teach in your hmi program about display event (not alarm) . And also using OB of plc?
There’s a complete lecture in my HMI course dedicated to system diagnostics. I’m only using OB1 in my courses but I might update my premium content with interrupt OBs.
I appreciate the time and effort you've put into this. Pls keep pumping these kind of lessons as they are gold to us.
But i have a QUESTION in terms of "byte swapping", would keeping the bits as you declared in the video instead of bit15 to bit8 then bit7 to bit0 affect the control of the vfd or not ?
Hi Chris,
Thanks for your nice words, happy to hear you get something out of these videos.
If you do not do the byte swapping, then your VFD control will not work (because your bits 0 to 7 will be switched with 8 to 15). Was that your questions?
@@PLCskilltree Yes sir you've answered my question
Thanks for the video. Just one question: Why don't you create a UDT for this block interface like you did for the others? (with Cmd, Stat, Cfg, Flt)
Good question Sergio. I usually create a UDT with Sts, Cmd, Cfg etc… structures for the parent module - in this example it would be the Refill Module.
Here I have chosen only to map the command and status of the telegram for the lower level VFD control block, where generated faults are part of the Flt structure of the higher level Refill block.
But this comes all down to preference. Yes you could create a complete Sts, Cmd, Flt, Par,… structure as well for the VFD but I prefer to keep that larger structure only for the parent module (e.g. refill).
@@PLCskilltree It makes sense since the number of interface signals to the block is low. Thanks a lot for the answer.
Hi, what if i want to run backwars the motor? how can i do it using tahat telegram? wich flag should i use?
You’ll have to set bit 11 “setpoint inversion” of the controlword to “1”.
My course (check the description below the video) comes with a sample application that shows you the exact logic first controlling the drive (including running the drive in the opposite direction)
thanks for your advanced tutorial , as a question? do you have tutorial about free telegram in your premium course?
The premium course uses the same telegram as the video. Why would you want to use a free telegram?
it's great to get this chance enhancing my plc structured code but it seems the guide sign up page is not good to send every time i got "This value seems to be invalid." error for all my emails trials
I have many sign ups each day, so the sign up page seems to work. Maybe try again another day.
it is working now flawlessly Many thanks@@PLCskilltree
Hi Hans chris again 😊. I've followed your steps and i created the "Standard Vfd Control FB", i've never thought it would be this easy especially the abuse of UDTs. But i wanted to ask about COMMISSIONING (inserting the motor data etc..), do you do it as a second step or do you follow another method ?
Thanks in advance 🙏
Hi Chris,
My video about creating the software is the first step, before the commissioning. Then during commissioning you will need to setup the VFD - give it an IP address, configuring the motor data like voltage, current, rpm, power etc....
I typically get the motor data from the data plate on the motor (picture with mobil phone) and I use the setup on the BOP screen of the VFD to set the applicable parameters to the correct values. I also write down the motor data for each motor in my project worksheet, just so I have a backup.
1- I apologize for skipping ahead of the video i'am just a bit excited😋
2- It seems that my Noob brain and its short term memory had a misunderstanding. I thought that "VFD control FB + commissioning" was enough and forgot about adjusting the VFD's
Parameters through it's BOP/AOP so it can be controlled by the PLC through PN like in our example.

Hi. Your videos are awesome. Im interested in your courses but i want to know what are the knowledge i will learn in the course. I already bought courses before but i didn't expect what i need. Thanks Hans
Thanks.
You will learn how to build structured TIA PLC and HMI applications from scratch, not just loose concepts or isolated examples - complete and fully functional applications.
If you go to my website www.plcskilltree.com, you can read much more about each course or bundle and there are plenty of testimonials from people who took my courses. That should give you a good idea.
How to create an HMI to control the speed after completing all these steps ?
That part is described in my premium training bundle, check the description below the video.
So as the video,i cant read Current ,Voltage from VFDs ?
In this tutorial I am using standard telegram 1 for data communication between VFD and PLC. If you select a different telegram, you can get current and voltage status. Remember to update the UDTs and control block as well with the additional status information.
@@PLCskilltree Can you recommend the best Telegram for control Plc and VFDs ?
Can this be simplified using Technology Objects?
As far as I know, technology object are for motion axes = servo axes, not for VFDs.
It can be done with Technology Objects as I've done it. However, in my instance it was still using Telegram 1, and it resulted in over simplifying everything. I will be using your method from now on, which I hope will give me more control. Thank you!
Dear friend... some of the blocks are already created in previously. So Need to create all by this session video itself. Then only easy understand this all
Thanks for your feedback. If you want to know how the program was made from scratch, please go and check out my courses in the description.
Pls sir make video on profibus communication
Profibus is kind of an outdated technology, I prefer to create videos on newer technologies
@@PLCskilltree ok but in India most place we are used sir
@@amarnathnsw9392 I understand
Hello Sir, Can you send me the backup please.
The complete application is available in my premium bundle. Check out the description below this video for more info 👍🏻
It’s to complex and there are a existing functions for this in the library of the software
I disagree about it being complex. It’s actually straightforward with simple steps. If you’re used to building structures for your plc applications then this example is relatively easy.
Can you send me a link to the library that you are mentioning?
May I ask you,sir? Is that method used for all VFDs those have Profinet interface or just for Siemens VFDs?
I have used these steps as well for e.g. Danfoss frequency converts. The steps are the same, just different telegrams for the data communication between vfd and plc.
@@PLCskilltree so it depends on the different manufacturers ? And how they define Control Word?
@@Huyautomation2901 yes, but 4 steps for structuring stay the same. I would always build UDTs that mirror the communication and I always build a standard control block.
@@PLCskilltree thank u for your reply.I hope u will make more video about PLC
