Install the Enhanced Redundancy System Chapter 3
A redundant system is comprised of two ControlLogix redundancy modules
working together that supervise the operating states and state transitions that
establish the basic framework for redundancy operations. The redundant pairs
provide a bridge between chassis pairs that let other modules exchange control
data and synchronize their operations. This illustration identifies the external
features of the module.
