6.6.4 Counter - Additional functions
The following additional functions may be set via the parameterization for every counter:
n
Gate function
The gate function serves 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-activates a digital output res.
releases a hardware interrupt depending on the counter value.
n
Hysteresis
The setting of a hysteresis avoids for example a high output toggling when the value
of an encoder signal shifts around a comparison value.
The illustration shows how the additional functions influence the counting behaviour. The
following pages describe these functions in detail:
