Rockwell Array OPC Tags

Ignition

An existing system uses a 100-element array that is relatively static, though there are 12 of them to handle.
My first question is: how do I create an OPC tag that reads the PLC tags?

My second question is: does it make sense to create memory arrays that get updated from the PLC on “occasion.?”

Of note, the arrays are string arrays, just to make it more interesting.

IA's Logix driver does not support reading/polling arrays as arrays. You need to address every element separately. If you don't need polling, you can set use a driven tag group, or script what you want with system.opc.readValues().
