Filter Tags by Their Data Source Type

You may filter the list of available tags by the type of data that they have been configured to read or write (i.e. analog, digital, or notebook).

1.  Click the Tag Selector button appearing in the Historical Data Viewer page's tool bar.

The Tag Selector dialog will open.

2.  Expand the Filter by Data Source Type drop-down list in the Filter Tags/Create Query section of the Tag Selector dialog.

3.  Select one of the following:

a)  All: Display all data types.

b)  AnalogDataSource: Display only those tags that read or write analog (continuous or decimal) data (e.g. "123.54" or "62.0") (i.e. analog input and analog output tags).

c)  DigitalDataSource: Display only those tags that read or write digital (discrete) data (e.g. "1", or "0") (i.e. digital input and digital output tags).

d)  NotesDataSource: Display only notebook tags.

The tags matching the data source type will be displayed in the Tag Selection list. You may now plot the located tag(s) adding them to the Selected Tags/Queries for Plotting list.
