Read in tag values from an external database

When you read in tag values from an external database, AVEVA Process Simulation retrieves the current time-averaged tag values from the external database and copies them into the Tag Value data in the External Data Manager. It does not copy the values to the associated model variables until you decide to set the model variables to the tag values. See Set model variables to the screened tag values for more information.

Read in tag values from an external database

1. Open the External Data Manager.

2. Select the tag collection that contains the tags that you want to read in values for, and then select Transfer.

   The Read/Write External Data window appears.

3. In the Tag List section, in the Input Processing area, select Read.

   The Tag Value data in the table updates to the current time-averaged values from the external database.

   The Quality column shows the current status of the tag values.

   

4. (Optional) If you know the quality of a retrieved tag value does not match the value shown in the Quality column, press and hold Shift and then select the tag's Quality badge to cycle through the different quality statuses:

   • Green: The tag has a good quality status.

   • Red: The tag has a bad quality status.

   • Yellow: The tag has a questionable quality status.
