On Signal Error

I am using the OPC connectivity plug in and it seems to be working pretty well
except one of my output signals from the plc is not working.

when I trigger the plc signal that is connected to my simulation the joint does not move
I get this error.

some of the other signals do seem to work. and make clamps move but not this one

havent tested all of them though to be honest.

help is appreciated let me know if you need more info

That error is from “OnSignal” method in a Python script “IO_Controls” in the “STA_010B” component, so you need to check what is happening there.
