CJ1M CPU11Peripheral port to SCADA

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

Add a CJ1W-SCU31-V1 and set it up as a Modbus RTU slave - RS485.

The best way to monitor any plc is by using its native protocol, in this case FINS.
