Modbus Kit - PAC Control

Yes, but you will need some Node-RED glue and tweak things a bit…
Check out this flow from @philip (second last post in the thread).

Configure Epic Serial Module GRV-CSERI-4

That’s disappointing. That was a useful hack. I know everyone thinks that Serial stuff is going away, but vendors keep selling me instruments that use it. For example, we bought a reactor system that came with Exlar slide valves with linear actuators. They came with software you could hook up to a COM Port on your computer. We wired them through a SNAP-485-422 module and were able to communicate with them via our Opto chart AND their software (not at the same time) without changing the wiring. …

Once you have the two Node-RED flows talking back and forth, move the serial data into PAC Control.
