In applications where wiring cost is a concern, it may be more cost-effective to distribute I/O points closer to the devices they control. Field I/O modules can pass I/O data to/from the controller with one single communication link. The Protos X field I/O system provides EtherNet/IP, Modbus RTU or TCP communication between the controller and field I/O points.
