Parameters > Citect.ini File Parameters > Trend Parameters > [Trend]InstantTrendIdleTime


Set this parameter to specify the number of seconds that data will be held in the cache for an instant trend without client display requests. If no requests for the data occur for this period of time, the cached data will be cleared and the instant trend will need to restart the cache for the next client display request.

Note: Increasing this value may increase the memory usage of the display client, which may impact performance.

Allowable Values: 0 to 1000000 (seconds).

Default Value: 600
