Features

Separate communication modules are available for different networks. Install multiple communication modules into the ControlLogix backplane to bridge or route control and information data between different networks. You can route a message through a maximum of four chassis (eight communication hops). You do not need a ControlLogix controller in the chassis.
ControlLogix-XT communication modules for extreme environments are available for EtherNet/IP, ControlNet, and Data Highway Plus and Remote I/O networks.

The 1756-DHRIO module supports messaging between devices on DH+™ networks. The remote I/O

functionality enables the module to act as a scanner for transferring digital and block-transfer data to and

from remote I/O devices.
