6 Functions
6.1.2 Window function
Under the window function, the window range is defined using the parameters window low "FL" (lower
value) and window high "FH" (upper value). The output switches when the current measured value (x)
is between the two limits [(x > FL) & (x < FH)].
The window function distinguishes between N/C and N/O contacts.
Requirement: Window high "FH" >= Window low "FL"
The window high "FH" and window low "FL" switching points have a fixed symmetrical hysteresis of
± 0.25 % of the measuring range.
