Can the 584 PLC support four Modbus Ports?



Yes , with the use of the NW-BM85C002. The 584 has only 2 Modbus Ports.To get four Modbus Ports you must connect the bridge to one of the Modbus ports and configure port 1 of the bridge as a Slave port. The remainng three ports of the bridge then need to be configured as Master ports. This will allow the 584 to support 4 Modbus Ports.
