Occasionally, it is necessary to synchronize the configuration data on a controller. For example, a replacement controller may have been installed or a power outage may have caused the data to not be synchronized. Synchronizing the data ensures that the most current information is on the controller.

  1. View the access controller details.
  2. Select actions menu and then choose Synchronize.
  3. A message appears requesting confirmation to synchronize the data. Select Synchronize to continue or Cancel to exit from the screen.
  4. When the synchronization process begins, the "Controller Synchronizing" event is displayed on the Events page. When the synchronizing process is complete, a "Controller Synchronized" event is displayed. To view more details, select the event.
    If "Controller Synchronization Error" is displayed, then synchronization has not completed because an error occurred while trying to synchronize the data on the controller. 

During synchronization, the controller will be unavailable, and the devices associated with the controller will behave in their offline mode. Events occurring during this time continue to be reported on the Events page. Depending on the timing, these other events may appear between the "Controller Synchronizing" and "Controller Synchronized" events.

Synchronization Statuses

  • Synchronization status: Preparing - Once Synchronization is selected, this status will display under Statuses on the controller's details screen and the Devices tree.
  • Synchronization status: Downloading - Once the synchronization commands are being sent to the controller, this status will display under Statuses on the controller's details screen and the Devices tree.
  • Synchronization status: Queued - This is the status for controllers after a gateway is synchronized because the gateway's downstream devices are also synchronized and may need to be queued. This status typically occurs when several controllers are configured for the gateway being synchronized. See Gateway synchronization.
  • Synchronization status: Failed - Synchronization of the controller was not completed so the latest changes might not be applied.
