Is it possible to feed changing IO signal values during a simulation? Like simulating a live welder current analog signal.

Have you tried connecting to a virtual PLC using OPCUA and mimic your analog signal from PLC? I use this to run various situations. for analog, you will need additional programming in PLC to convert to word then send to a defined range to robot…unfortunately in Omnicore you`ll need to map one by one bit and not the full word (i paste a topic regarding this).

I haven’t tried that, but that is a good idea. Thank you!
