[Trend]CacheSize2

Determines the number of samples that can be stored in the cache of trends with sample period >= 250ms and < 1 second.

If your sample period is <250 ms or >= 1 second, CitectSCADA uses a different parameter to set the number of samples the cache can store. See the following table:

[Trend]Parameter	Sample Period	Default Value (No. of samples)
[Trend]CacheSize0	< 50 ms	8188
[Trend]CacheSize1	>= 50 ms and < 250 ms	2044
[Trend]CacheSize2	>= 250 ms and < 1 second	1020
[Trend]CacheSize3	>= 1 second and < 5 seconds	764
[Trend]CacheSize4	>= 5 seconds and < 10 seconds	508
[Trend]CacheSize5	>= 10 seconds and < 20 seconds	380
[Trend]CacheSize6	>= 20 seconds and < 50 seconds	252
[Trend]CacheSize7	>= 50 seconds and < 100 seconds	192
[Trend]CacheSize8	>= 100 seconds	128
