Write tag values to the external database

When you write tag values to the external database, AVEVA Process Simulation overwrites the external database values with the current Tag Value data in the External Data Manager. The software applies the Tag Value data regardless of whether the associated model variables are specified or calculated.

If needed, you can manually update the Tag Value data in the External Data Manager before you write the tag values to the external database.

Write tag values to the external database

1. Open the External Data Manager.

2. Select the tag collection that contains the tag values that you want to write to the external database, and then select Transfer.

   The Read/Write External Data window appears.

3. In the Tag List section, in the Output Processing area, select Get.

   AVEVA Process Simulation copies the values for all the associated model variables (Sim Value) to the Tag Value data.

   The software also updates the Quality for the tag. If the solved status for the associated model variable shows a successful solve, the quality is good (green badge). Otherwise, the quality is bad (red badge).

4. Review the tag values and change the Quality if needed.

5. In the Time Selection section, in the Start Date & Time box, enter the date and time that you want to use as the timestamp for the write operation. You can use the dropdown menu to select the date from a calendar view.

6. In the Tag List section, in the Output Processing area, select Write.

   The software adds a new record with the specified timestamp and Tag Value data to the database.
