1765 ControlLogix Communication Modules 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.

If your application requires Use this network
• Plant management (material handling)
• Configuration, data collection, and control on a single, high-speed network
• Time-critical applications with no established schedule
• Inclusion of commercial technologies (such as video over IP)
• Internet/Intranet connection
EtherNet/IP network
• High-speed transfer of time-critical data between controllers and I/O devices
• Deterministic and repeatable data delivery
• Media redundancy
• Intrinsic safety
• Redundant controller systems
ControlNet network
• Connections of low-level devices directly to plant floor controllers, without interfacing them through I/O modules
• Data sent as needed
• More diagnostics for improved data collection and fault detection
• Less wiring and reduced start-up time than a traditional, hard-wired system
DeviceNet network
• Plant-wide and cell-level data sharing with program maintenance
• Data sent regularly
• Transfer of information between controllers
Data Highway Plus network
• Connections between controllers and I/O adapters
• Data sent regularly
• Distributed control so that each controller has its own I/O and communicates with a supervisory controller
Remote I/O network
• Modems
• Supervisory control and data acquisition (SCADA)

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.

1756-Controllogix-Overview
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.
