Configuring Auto-synchronization of Digital States

Auto-synchronization with the SynchInterval Registry Key

The Historian OSI PI Collector allows transferring digital sets from the PI Server to Historian as enumerated sets. The digital sets from the PI Server are transferred to Historian not only during collector startup but also with the frequency of the Synch Interval.

Auto-synchronization of digital states can be configured with the SynchInterval Registry Key. The frequency at which the OSI PI Collector fetches the digital set from the PI server to Historian is determined by the value configured for this key, which is specified in minutes.

Values for the SynchInterval Registry Key

The default value of this key is 0, which indicates there is no synchronization of the digital set.

Set this registry key to a value greater than 0 if you want the OSI PI Collector to automatically fetch the digital set from the PI Server to Historian.

For example, the OSI PI Collector fetches the digital set from the PI server to Historian every 10 minutes if the value configured in this key is 10.
Note:
  • The collector must be restarted to apply the change in the value of this registry key.
  • This key is available for all Historian Collectors, but it is functional only in the OSI PI Collector.
  • Digital sets from the PI Server are transferred to Historian only during collector startup.
