AVEVA™ Communication Drivers

Manual tag synchronization

  • Last UpdatedAug 29, 2024
  • 1 minute read

This system item ( $SYS$UpdateTagInfo) is provided for manual synchronization of tag database. If the device is secured (Password protected), use this item to synchronize tag database.

The system item $SYS$UpdateTagInfo can be accessed by any client application.

The tag database will be uploaded from the device if value True is poked to this item.

Note: If Use Persisted Tags is enabled, the original file will be renamed to <####>_temp.aaTDB (where ### represent the serial number of the device). If the Communication Driver fails to upload tags from device, it will use the renamed file to recover the database. The temporary file (<####>_temp.aaTDB) will be deleted after the tag database is uploaded successfully.

Poking the value False will not affect the tag database.
