Hi

I want to communicate my device with Proface make HMI - PFXGP4301TA.

But I dont know if this HMI has Modbus RTU or Modbus TCP communication interface?
Also if Master or Slave?
 
A GP4301TAD has a serial port that you can use for Modbus RTU master or slave.
The ethernet port can either be configured as master or slave. It is even possible to use the ethernet port with more than 1 device, and 1 device is the Modbus TCP master while the 2nd device is a modbus TCP slave.
