I’m working on a quick screen to simulate a process I’ve written in RSLogix 5000.
As you can see, I’m using a user defined datatype called “BELT_CONTROL” for every tag used in this simulation. Using the OPC browser, I dragged and dropped the entire folder to my tag list in Ignition. That is folders “BELT1” and “BELT2.”
It appears as if some of the tags are linking to the PLC properly (all of the tags in “BELT1” folder), however a select few in the folder “BELT2” have a green question mark and are not reading values from the PLC.
Other misc. info:
I’m using the latest stable version of Ignition.
On the Ignition configuration page, the PLC says “Protocol: EIP,” which I have not seen before.
