Remote I/O Modules

Remote I/O refers to I/O modules that are not in the local chassis and connect to the controller via a communication network. There are several families of I/O modules that are remote from the controller:
  • I/O modules in a remote chassis via a network bridge module
  • Distributed I/O families
  • On-Machine™
     I/O families
The
ControlLogix®
 controller supports the use of remote I/O via these networks:
  • EtherNet/IP™
  • DeviceNet®
  • Universal remote I/O
For more information about the network configurations that can be used to connect remote I/O, see Communication Networks.
