Ignition 8.1 - Allen bradley - How to write OPC Item Path

Ignition
1

I need to communicate an Ignition 8.1.47 with an Allen Bradley PLC through a device (PLC3) of type Allen-Bradley Logix Driver.

The thing is, I'm not clear on how to fill in the OPC ItemPath field in order to communicate with the memory addresses. For example, the boolean B9:15/6.
I tried with ns=1;s=[PLC3]B9:15/6 but it gives me a Configuration Error.

How should I fill in the OPC Item path to reach the signal?

The AB Logix driver is for ControlLogix and CompactLogix devices only, and only for relatively modern firmware.

There is no IA driver for the ancient PLC3 family. The PLC5 driver might work.

Please share the precise model and version of your PLC.
