About Qualified Points and Logged Expression Lines

If you do not specify a project, the Base project is used.

If you change the Base project on the Chart tab of the CIMPLICITY Trend Control Properties dialog box and:

If a Point ID


Is fully qualified

Continues to draw the line using the same data source.

Is not fully qualified

Trending assumes the data is coming from the base project. If you change the base project, Trending attempts to find the point in the new base project.

This feature is useful if you have two or more projects with the same Point ID (for example, BLDG_1 project and BLDG_2 project) and you want to be able to switch between them.

Note: One of the sources for a Logged expression line is always a column in a group log table.
