ControlLogix Redundancy Module 1756RM2XT
The ControlLogix controller supports controller redundancy. In a redundant controller system, you need these components:
• Two 1756 chassis, each with the same of the following: – Number of slots – Compatible modules in the same slots – Redundancy firmware revisions in each module – Two additional ControlNet nodes outside the redundant chassis pair if the application uses ControlNet networks
• One 1756-RM, 1756-RM2, 1756-RMXT, or 1756-RM2XT redundancy module per chassis that is connected by a 1756-RMCx cable (the 1756-RM2 redundancy modules cannot be paired with the 1756-RM redundancy modules)
• Up to two 1756-L6x or 1756-L7x controllers, or a combination of the two, in each chassis
• Up to seven enhanced or standard (not mixed) communication modules, that is, 1756-CN2/B, 1756-CN2R/B, 1756-CN2RXT modules 1756-EN2T, 1756-EN2TR, or 1756-EN2TXT modules
