Hi All,
I need 16 HMI's and 4 PLC's with devicenet aboard each PLC. Spec is schneider Twido PLC's & schnieder HMI's.
The norm is to connect 1 HMI as master to the PLC using modbus. The Plc could have 2 ports. Is it possible to have multiple masters talking to the PLC?
The whole system will be connected to a vijeoCitect SCADA server.
Question is if the HMI's have a ethernet port could one connect 12 of them to the lan and access them through citect and then the other 4 HMI's to the other 4 PLC's which in turn could be connected via lan to the citect. There are only 4 cells so this would be OK.?
