1756-EN4TR modules support Parallel Redundancy Protocol (PRP) with firmware revision 4.001. Updated the 1756-EN2F EtherNet/IP communication rate specification. When the 1756-RIO module is used as a remote I/O adapter, the chassis must include a ControlLogix controller.

Backplane double data rate (DDR) communication 1756-EN2TR and 1756-EN2TRXT modules: Improved backplane communication between the controller and module (series B) when using the 1756-L7x controller (and later revisions). 1756-EN3TR module: Improved backplane communication between the 1756-L7x (and later revisions) controller and module.

The 1756-EN2TR is an communication module that support Ethernet I/P communication protocol. This module has Two (2) RJ45 port for connecting or implementing Redundant Ethernet network. It also has a USB 1.1 port.

Module operates in a broad temperature spectrum, -20...70 oC (-4...158 oF), and meets ANSI/ISA-S71.04-1985 Class G1, G2 and G3, as well as cULus, Class 1 Div 2, C-Tick, CE, ATEX Zone 2 and SIL 2 requirements for increased protection against salts, corrosives, moisture/condensation, humidity, and fungal growth.
