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.
using serial Modbus RTU (RS-485) or Ethernet Modbus TCP or Ethernet/IP communications protocols
Protos X "Xpansion" I/O
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.
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.
