ciao,
there's a specific tutorial on how to connect two Opta using Modbus TCP/IP and Arduino PLC IDE.
https://docs.arduino.cc/tutorials/opta/opta-modbus-tcp-plc-ide/
and the same using Modbus RTU
https://docs.arduino.cc/tutorials/opta/getting-started-with-modbus-rtu/ using arduino language.
if you want to interface an HMI here's an example with Weintek
take your time to learn 
Hello
