Hi,

It is clear that SСADA is a master of the network.

Then tell us which Unitronics PLC you want to connect and which communication channel.

Possible variants of physical communication channels RS232, RS485, Ethernet, CAN,  GPS. Accordingly, the communication protocol is possible MODBUS, MODBUS TCP.

Maybe I missed something else. Clarify your task and I think the forum participants will be able to help.
