AutomationDirect offers EtherNet/IP protocol communication for the Protos X line of field I/O. The Protos X "Xpansion" field I/O system is a modular system consisting of a Bus Coupler and its associated input/output terminals.
2 to 16-point discrete I/O terminals and 2 to 8-channel analog I/O terminals are available. Up to 64 terminals per assembly and 255 I/O terminals total are possible. The Modbus and EtherNet/IP Bus couplers provide connection options to hundreds of industrial control devices.
Bus couplers are now available in four configurations. PX-TCP1 and PX-TCP2 server bus couplers offer Modbus TCP protocol over Ethernet. The PX-MOD slave bus coupler utilizes Modbus RTU/ASCII protocol over RS-485.The new PX-EIP1 server bus coupler uses EtherNet/IP protocol over Ethernet. The PX-EIP1 module has one RJ45 Ethernet 10/100 Base T port for connection to an Ethernet client.
