Stopwatch (Ta)
The value of “On”, ”Off” can be set/modified in parameter
mode.
Timing diagram
fa = Input frequency
Description of the function
The trigger measures the signals at input Fre. The pulses
are captured during a configurable period G_T.
Q is set or reset according to the set thresholds. See the
following calculation rule.
Calculation rule
If the threshold (On) > threshold (Off), then:
Q = 1, if fa >= On
Q = 0, if fa < Off.
If the threshold (On) < threshold (Off), then Q = 1, if
On <= fa < Off.
Analogue Comparator
Description of function
The output is set and reset depending on the difference
Ax - Ay and on two configurable thresholds.
Connection
Description
Input Ax, Ay
Input the analogue signals of which
you want to determine the delta at
the inputs Ax and Ay.
Use the analogue inputs AI1...AI8,
the analogue outputs AQ1 and
AQ2.
AI1...AI8: 0 - 10 V corresponds with
0 - 1000 (internal value).
