We will build a SCADA system using Modbus/TCP Protocol. SCADA Host (SCADA software) will be client and read data from PLC/RTUs, which are thought to be servers. However, RTU/PLCs need to communicate with each other also. So, for an RTU/PLC, is it possible to open double socket/channel (via ethernet port) one will treat as Client and the other will treat as Server? Or will we need 2 ethernet ports for this purpose?
