Unconfigured Keeper
The example below shows the Keeper Status dialog box where a module has an
unconfigured status. Besides the status shown, the module status display indicates
Keeper: Unconfigured (node address changed).
This error results when the module’s node address has been changed. After
changing the node address, the module was used as a replacement and inserted
into the redundant chassis.

To correct this anomaly, do one of the following:
• Select the unconfigured module and click Update Keeper.
• Reschedule the ControlNet network.
