I am currently working on integrating a 3rd party heater system (Watlow) into our PLC. I am able to read from the device however anytime I try writing the attempt is unsuccessful.
I currently I am using monitor mode to force output values. I have also tried assigning a value to the process variable attached to the output. Neither seems to work. I am fairly confident I am writing to the correct registers on the 3rd party device and think it is something on the B&R that I haven’t configured properly.
I am using AS 4.9.6.42
The module used for the Ethernet connection is X20IF10D1-1.
Does anyone have ideas on why I would be able to read from the device but not write to it?
