Starting in Sedona TXS-1.2, each Sedona device component (SedonaDevice or SedonaJen6lpDevice) has two properties related to synchronizing time with Niagara station time:
Time Sync Enabled
Allows for periodic (automatic) time synchronization messages to be sent from the Niagara station to this device. The default value is false.
If set to true, automatic (periodic) time synchronization from Niagara can occur. To achieve this, configure the built-in Time Sync Trigger of the SedonaNetwork or SedonaJen6lpNetwork from the default “Manual” (no periodic synchronization) to either “Daily” or “Interval”, with the needed values.
Time of Last Sync
Read-only timestamp of when the last successful time sync of the device from the station occurred (whether a periodic message, or from a manual “Sync Time” action). Displays null if no time synchronization has occurred.
Each Sedona device also has a Sync Time action, to send an immediate time synchronization message to the device—note this does not require Time Sync Enabled to be true. A “network level” Sync Time action is also available—this affects only those devices that are configured as Time Sync Enabled.
See the following for details on implementing time synchronization:
