Swinging Door Compression
A Filter is pre-defined for each tag.
When a new value comes in a value vector slope
is calculated from the last stored value and
compared to min max range slopes (S1, S2 )
When a value vector slope is outside the slope
filter...
The filter is then used to define the minimum and
maximum range of slope deviation for the
vector.
