The following procedure explains how to use the Tag Browser to assign a trend pen to tag data from a Remote History provider. Using the Tag Browser to select tags eliminates the need to manually enter each tag name and reduces the likelihood of errors.
The remote node name you specify in the Access Name does not have to be the actual name of the node where the tag resides. But, you must create an Access Name to define the remote history provider as a tag source. For more information about creating an Access Name, see Set up access names.
Define a remote history provider as a tag source
-
Create an Access Name that specifies the node name where the history provider is located.
-
Double-click the historical trend to open the Historical Trend Configuration dialog box.
-
Double-click a pen's Tagname input box to show the Select Tag dialog box.
-
Select Define Tag Sources to define the remote history provider as a tag source.
-
Select the Tag Source arrow and select the new remote history provider tag source in the list, or select the Tree View button and select the tag source in the tree view pane. The Select Tag dialog box refreshes and shows the tags from the selected remote history provider.
-
Select the tag that you want to assign to the historical pen and select OK. The Historical Trend Configuration dialog box reappears with the selected tag listed in the pen's Tagname box as: AccessName:Item.
-
Replace the AccessName: portion with the history provider name you defined in the Distributed Name Manager.
For example, HistPrv1.tag_name
This process may seem cumbersome, but after you have defined the history provider as a tag source in the Tag Browser, each time you double-click another tag input box, you simply double-click the tag name in the Tag Browser, and then replace the AccessName: portion with the history provider name.
In WindowViewer, if run-time changes are allowed for the historical trend, when the user selects a pen button to change the tagname, the Tag Browser appears but only the local application's tags are accessible.
