Allen-Bradley 1756-EN2TXT EtherNet/IP Communication Modules

Allen-Bradley 1756-EN2TXT EtherNet/IP Communication Modules

Description

The Allen-Bradley 1756 ControlLogix CIP Safety I/O Modules provide a reliable, flexible, and scalable solution for integrating safety in industrial automation and control systems. Fitted with Compact GuardLogix® 5380 or GuardLogix 5580 controllers, offering functional safety rated up to and including SIL3 and PLe while supporting CIP safety bridging and routing functionality.

Communication Connections

A ControlLogix system uses connections to establish communication links between devices. The types of connections include the following:

• Controller-to-local I/O modules or local communication modules

• Controller-to-remote I/O or remote communication modules

• Controller-to-remote I/O (rack-optimized) modules

• Produced and consumed tags

• Messages

• Controller access with the Studio 5000™ environment

• Controller access with RSLinx® software for HMI or other applications

You indirectly determine the number of connections the controller uses by configuring the controller to communicate with other devices in the system. The limit of connections ultimately resides in the communication module you use for the connection. If a message path routes through a communication module, the connection that is related to the message also counts towards the connection limit of that communication module.

The Ethernet Industrial (EtherNet/IP) network protocol is an open industrial-networking standard that supports both real-time I/O messaging and message exchange. The EtherNet/IP network uses off-the-shelf Ethernet communication chips and physical media.
