Hi,
We have project to monitor machine details in Zenon SCADA. For this we need to establish communication between Omron CJ1m-CPU11 and CPU12 with Zenon ( Zenon supports more than 300 PLC Protocol) . Right now PLC Port2-RS232 already used for HMI I would like to know the best possible way to communicate with this PLC either via Modbus, FINS or OPC.
Regards
Sandy
