1756 controllogix overview
The Controllogix Gateway provides different communication modules for each of the different networks listed below. You have the option to put these variousmodules into the ControlLogix backplane chasis to connect or route control and information data between these various networks. You can send a message through four chassis maximum (eight communication hops). Please note that you will need a ControlLogix controller in the chassis.
Note that the ControlLogix-XT communication modules is available for extreme environment for EtherNet/IP, ControlNet, and Data Highway Plus and Remote I/O networks.

Allen Bradley Data Highway Plus and Remote I/O Networks
The Data Highway Plus (DH+) network supports messaging between devices. The remote I/O link connects to remote I/O chassis and other intelligent devices.
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.
The 1756-RIO module can act as a scanner or adapter on a Remote I/O (RIO) network. In addition to digital and block-transfer data, the 1756-RIO module transfers analog and specialty data without message instructions.
