101 Input Filter Time Constant (FILTIME)...............................................................................CWR
The filter time in minutes (floating point value) when USER is specified as the filter type.
Otherwise, it is 0.0.
value Any floating-point value in minutes
where
0.0 = no filtering (last sampled value is the input value)
1.0 = a 1 minute
1000.0 = 1000 minutes (maximum value)
Note that exceptionally large values tend to maintain the previous value whereas very small
values tend to maintain the most recent sampled value.
