About PLC Communication Modules

PLC communication modules add or expand fieldbus and network connectivity on a PLC backplane or remote rack, covering Ethernet/IP, Profinet, Profibus, Modbus TCP/RTU, EtherCAT, DeviceNet and serial (RS-232/485) interfaces. When selecting a module, confirm the host PLC family and backplane compatibility, the required protocol and port count, deterministic cycle time needs.
