First step is to connect to the device from Ignition’s OPC-UA server with a device driver. The driver/protocol will depend on the PLC type and model. What device are you using?

Have you looked over the user manual for modbus device setup?

Do your counters have modbus addresses assigned in Control Expert? Ignition cannot reach memory that doesn't.

Show the Control Expert settings where you assign a word memory address to your counters. It isn't visible in your first screenshot.

OK. Try manually creating Ignition OPC tags with one of these OPC Item Paths:

[ProcessingMainChain]HR334.0
[ProcessingMainChain]HR335.0
[ProcessingMainChain]HR336

or possibly:

[ProcessingMainChain]HR333.0
[ProcessingMainChain]HR334.0
[ProcessingMainChain]HR335
