Module Status Leds - Rockwell Automation ICSTT-RM280N-EN-P Manual

4. Operation

4.2. Module Status LEDs

There are six Module status indicators on the Module Front Panel: three Healthy, one
Active, one Standby, and one Educated. The Healthy indicators are controlled directly by
each Module slice. The Active, Standby, and Educated indicators are controlled by the FPU.
The FPU receives data from each of the Module slices. It performs a 2oo3 vote on each data
bit from the slices and sets the indicators accordingly.
The Module status indicator modes and their meanings are described as follows:
INDICATOR STATE
