In certain applications, it is more cost-effective to distribute I/O points closer to the devices they control and pass I/O data to/from the controller with a single communication link. The Protos X field I/O system does this using EtherNet/IP or Modbus links between the controller and field I/O.

The Protos X "Xpansion" I/O System ... using serial Modbus RTU (RS-485) or Ethernet Modbus TCP or Ethernet/IP communications protocols
Protos X Bus Couplers
Serial Modbus RTU, Ethernet Modbus TCP and EtherNet/IP bus couplers are available offering connection options to hundreds of industrial control devices including most popular PLCs and SCADA/HMI packages. Protos X bus couplers are available in four configurations.
- The PX-TCP1 and PX-TCP2 offer Modbus TCP protocol over Ethernet
- The PX-TCP2 provides an additional port which can act as a switch to other couplers of the same type
- The PX-EIP1 utilizes EtherNet/IP protocol over Ethernet
- The PX-MOD utilizes Modbus RTU/ASCII protocol over RS-485
The Protos X compact, modular field I/O system
Allows a user to install remote field I/O devices without having to invest in another controller. The unique slim design and low cost of the Protos X I/O makes it the most practical distributed I/O available today. The ultra-slender form factor makes it easy to install on or near machine or application components, saving time and excess field wiring and speeding up troubleshooting. The ultra-compact design makes it perfect for applications where a typical PLC or I/O solution simply would not fit.
