Disabling a Point from Trend Log
Trend log memory collects and saves up to 200 of the most recent change-of-state
(COS) conditions from up to 20 trend points in a controller. A trend point is a point
that is designated (in the controller’s application program) to report changes in its
state/value to the trend log memory.
Operators can request a trend log report which extracts the trend point COS
information from the trend log memory and outputs the trend information in the
XI581/2 display window.
This function disables a point so it cannot contribute associated COS activity to the
trend log memory and it cannot appear in a trend log report output.
NOTE: To enable a point’s trending capability, see section "Selecting Points by
User Address" (page 53).
