Export Diagnostics
You can also click Export Diagnostics in the event of a module fault in the 1756
redundancy module. Click Export Diagnostics to collect and save diagnostic data
from the redundancy module and its partner, if an unrecoverable firmware fault
occurs. A nonrecoverable fault is indicated by a red ‘OK’ light on the front of the
redundancy module, and a fault message scrolling across the marquee display.
When you click Export Diagnostics, information is recorded that can be used by
Rockwell Automation engineering to determine the cause of the fault.
Because diagnostic information for the redundancy module and its redundancy
partner are recorded, a communication path to the partner RM is also part of the
process of obtaining the diagnostics.
Follow these steps.
1. Click Clear Fault if it is enabled, as it may first be necessary to clear any
faults before using Export Diagnostics.
2. Click Export Diagnostics.
IMPORTANT Only Export Diagnostics when requested to do so by Rockwell Automation
Technical Support.
