5.4 Converting a redundant PGM to a non-redundant PGM
You can convert a redundant PGM to a non-redundant PGM on-process.
Ensure that the current primary PGM is physically configured with the odd Device Index. If not, enable
synchronization, wait for initial-sync to complete, and manually command switchover.
Perform the following steps to convert a redundant PGM to a non-redundant PGM
In the Monitoring view, double-click the secondary PGM.
The secondary PGM configuration form appears.
Click the Redundancy tab.
Click Disable Synchronization. Wait for the command to complete.
The synchronization between the primary and secondary PGM terminates. A 'Not Synchronized' diagnostic
alarm is generated by both the primary and the secondary PGM.
Delete the secondary PGM function block from the Monitoring view.
Disconnect the redundancy cable from the primary PGM.
Remove the secondary PGM hardware by removing the PGM module and its IOTA.
In the Project view, right-click the primary PGM and select Module Properties.
The primary PGM configuration form appears.
Clear the Module is redundant check box.
The secondary PGM icon is deleted from the Project view. The primary PGM icon changes from a
redundant to a non-redundant icon.
Load the non-redundant PGM.
The PGM icon in the Monitoring view indicates that the PGM is now non-redundant.
