Configuring Pens to Display Remote Trend Data

Historical trends can display tag data from both local and remote history providers. You can assign trend pens to display data from a remote history provider.

To display a tag from a remote history provider

1. Double-click on the historical trend to show the Historical Trend Configuration dialog box.

2. In each pen's Tagname box, type the reference to a remote history provider. The format of the reference to a remote history provider is:

   history_provider_name.tag_name

   Example:

   TankFarm1.Pump1RPM

   Each pen of a historical trend can refer to a different remote history provider.

3. Click OK to save your configuration changes.

   Note: The .TagID dotfield cannot be used in remote history provider tag references.
