Enabled?

Select Enable Trend Log to have the control module collect trend data. Refer to Trends in WebCTRL Help for details.
When Enabled, this microblock records its value in the control module's memory at the Interval you define. Each trend may be individually enabled and disabled, and when disabled, consumes no memory. You can also determine the Number of Samples you would like to collect.

Editing Privilege

If you change the Editing Privilege, all the properties in that microblock are assigned to that one editing privilege, which is not always desirable.
