Contact Rockwell Automation Technical Support
If you tried to use the event logs to troubleshoot your redundant system and are
unsuccessful, prepare to contact Rockwell Automation’s Technical Support by
exporting the event logs of both the primary and secondary redundancy
modules. The technical support representative who assists you will use those files
to help determine the cause of a switchover or other anomaly.
For more information about exporting the event logs, see Export Event Log Data
on page 124 .
Keeper Status Causing
Synchronize Failure
To determine if a keeper status anomaly is causing a synchronization failure, you
can view the module status display of the ControlNet modules, or you can check
the keeper status by using RSNetWorx for ControlNet software.
TIP To avoid anomalies with the Keeper Status, always reset the ControlNet
module configuration of a module being used as a replacement before
inserting and connecting the module in a ControlNet network.
For more information about resetting the ControlNet module configuration,
see Automatic Keeper Crossloads on page 102 .
