Delta HMI with CLICK PLC

I'm working on a budget project where I need to connect a Delta HMI to a CLICK plc. It looks like the only communication allowed between the two is Modbus RTU. I am not sure how to set this up in the two, or how to annotate the addressing correctly. As a newer engineer I haven't had to use modbus before, thankfully, but here I am. Has anyone had experience with this.

Modbus addressing works the same as other addressing. The main difference is that it's numbers only. Use the "Address Picker" in the Click software. Select "Show Modbus Address". Use 984 addressing. Haven't used a Delta. If it doesn't have a Modbus RTU selection for the PLC, use Schneider Modbus RTU.
