Removal of the powered secondary PGM from its IOTA.
Removal of PROFIBUS network cable from the secondary PGM.
When the single FTE link to the primary and/or secondary PGM is disconnected, this does not result in loss of

5.6.1 Enabling Synchronization
Use the following procedure to initiate a synchronization command manually to a redundant PGM pair.
You can view the active PGM pair in the Monitoring view in the Control Builder.
Perform the following steps to enable synchronization
In the Monitoring view, double-click the primary PGM icon.
The PGM block configuration form appears.
Click the Redundancy tab.
Click Enable Synchronization.
Click Yes to confirm the action and issue the synchronize command.
Confirm that the Auto Synchronization State becomes ENABLED.
