4.5 Counter additional functions
The following additional functions may be set for the counter via the
parameterization of the 050-1BA00:
n
Gate function:
– The gate function serves for the start, stop and interrupt of a
count function.
n
Latch function:
– An edge 0-1 at the digital input "Latch" stores the recent
counter value
in the latch register.
n
Comparison:
– You may set a
comparison value
that activates res. de-acti-
vates the digital output res. releases a process interrupt
depending on the
counter value
.
n
Hysteresis:
– The setting of a
hysteresis
for example serves the avoidance
of many toggle processes of the output and/or the interrupt,
when the value of an encoder signal shifts around a
compar-
ison value
.
The illustration shows how the additional functions influence the
counting behavior. The following pages describe these functions in
