FIX 32 app won't write to ControlLogix
I have a Fix32 V7 application. I am adding a new OPC driver to a ControlLogix PLC. I have created a AI, AO, and a AR tag. I can read the PLC's tag data in the AI, and the AR tags. The AO and AR Item in the OPC have "Enable Blocks Write" checked.
I am adding a couple Data Links to my application. One is set up with the AO tag and the other is the AR tag. Both Data Links are set up with "Allow Data Entry" and "Numerical Data" format checked.
When I run the app., niether Data Link will write to the PLC.
