controller
Prerequisites
• Control Builder is running
• Tree windows are open
• Make sure that the current primary C300 Controller is physically configured with the
odd Device Index. If not, enable synchronization, wait for initial-sync to complete,
and manually command switchover.
• The Primary C300 block must have RDNAUTOSYNC parameter set to disabled. If
not, issue the Disable Synchronization command (to either the primary or secondary
controller). A ‘Not Synchronized’ diagnostic alarm will be generated by both the
primary & secondary controllers
Considerations
This procedure can be performed on-process. All illustrations used in the procedure are
