PAC R1 controller with Omron nb5q-tw00b

My client has a problem. Can PAC R1 controller communicate with Omron nb5q-tw00b touch screen? the liquid level and the start and stop of the control pump are displayed on the touch screen.

Thank you!

The spec sheet shows it supports modbus - so yes it is possible. Could be simple if you need the screen to read some IO points/scratchpad over Modbus TCP, as that is built in to the PAC brains.
If you need the PAC to be the master or need to use serial or need access to strategy variables, then you will need to work with the Opto Modbus SDK which is a chart and some subroutines you bring into your strategy.
