Refresh the Tags for a Linked I/O Device

You can manually refresh the tags for an I/O device that is linked to an external data source. This will load any changes that have occurred in the external data source into Plant SCADA Studio.

Note: If the Automatic Refresh property is set to True for a linked I/O device, a tag refresh will occur automatically when you compile your project.

To manually refresh linked tags:

1. In the Topology activity, select I/O Devices.

2. Select Refresh Tags from the Command Bar. The Refresh Linked Tags dialog box will appear.

   

   The Select Linked I/O Devices section lists every linked I/O device in your project (and included projects).

3. To refresh the tags for a device, select it and click Refresh.

   This updates your project with the latest tag values for the selected I/O device. If you use Plant SCADA to modify any I/O device tags, your modifications will not be overwritten on refresh.

4. When you are finished, click Close.
