Allen-Bradley 1756-RM2XT ControlLogix Redundancy Module

Allen-Bradley 1756-RM2XT ControlLogix Redundancy Module

Description

ControlLogix 5580 and ControlLogix 5570 controllers support controller redundancy. In a redundant controller system, you need these components:

• Two 1756 chassis, each with the same of the following:

- Number of slots

- Modules in the same slots

- Redundancy firmware revisions in each module

- Approved module firmware revisions for use within ControlLogix Redundancy systems.

• One 1756-RM2, 1756-RM2K, or 1756-RM2XT module per chassis that supports the following:

- One or two ControlLogix controllers of the same family. ControlLogix 5580 controllers support redundancy with Studio 5000 Logix

Designer application, version 33 or later.

- For ControlLogix 5580 controllers, as many as seven EtherNet/IP communication modules.

- For ControlLogix 5570 controllers, as many as seven ControlNet or EtherNet/IP communication modules in any combination.

• One or two 1756-RMCx cables
