I am using SCADA (InTouch) software from Wonderware, but now my customer wanted to connect the SCADA system directly to the RTU/PLC using modem. Can anyone out there tell me how to do it?
What type of Modbus I/O server support multi modem connection and how to configure it when I need to point to particular RTU/PLC by selection.
