Communication Modules

ControlLogix Communication Modules Overview

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.

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
• Fieldbus transmitters and actuators • Closed-loop control • Process automation	Foundation Fieldbus network
• Modems • Supervisory control and data acquisition (SCADA)	Serial network
Connections to existing DH-485 networks	DH-485 network
SynchLink fiber-optic communication to: • controllers. • power distribution systems. • PowerFlex 700S drives.	SynchLink network
