It is hard to understand the question and I’m not sure why you are creating the RDREC and WRREC instead of using the example that Christian provided. I think we would be able to help you better if we could have a call with Teamviewer.

In order to arrange that, I will first need you to create a support case by going to:

https://mysupport.hms.se

That will get routed to Christian, who is an expert on this device, and he will be able to help you directly.

Thank you!

I created support case ID: 202106-31341

Also I found CANopen with S7-1200 manual where I found functional block (FB) which show how to take drive contol.

Start function and Velocity
But how to add hardware ID and NODE ID??
