Description
Input Polarity NORMAL
INVERTING
NORMAL For the normal polarity, the open
to closed transition is considered
closed. For the inverting polarity,
the closed to open transition is
considered closed
PuLS
Pulse Input
Mode
PLS.A = PULSE MODE,
PLS.C = KYZ MODE
PULSE
MODE
In pulse mode, either leading, or
trailing edge of the input pulse is
recognized as an event. In KYZ
mode, both leading and trailing
edges of the input pulse are
recognized as separate events.
Polr
Pulse Polarity nor = NORMAL (N.O.),
InS = INVERTING (N.C.)
NORMAL For the normal polarity, the open
to closed transition is considered
a pulse. For the inverting polarity,
the closed to open transition is
considered a pulse.
It has no meaning in KYZ mode
where both transitions are used.
dbnc
Debounce
Time
1-100 ms
10 ms
The amount of time while the
state of the digital input should
not change to be recognized as a
new state. Too low debounce time
could produce multiple events on
the input change.
The debounce time is applied the same for all digital inputs. If you change
the debounce time for a digital input, the same debounce time is
automatically assigned to the others.
