5.6.6 Counter - Additional functions
5.6.6.1
Overview
The illustration shows how the additional functions influence the counting behavior. The
following pages describe these additional functions in detail:
5.6.6.2
Gate function
n
Starting, stopping and interrupting a count function of
counter 0
to
counter 2
exclu-
sively happens via the SW gate by setting the SW gate of SFB 47.
n
Starting, stopping and interrupting a count function of
counter 3
happens via the
internal gate (I gate). The i gate is the result of logic operation of HW gate and SW
gate. The HW gate evaluation of the connection
‘Gate 3’
may be deactivated by the
parametrization. With a de-activated HW gate evaluation the triggering exclusively
happens by setting the SW gate of SFB 47.
The parametrization defines if the gate interrupts or aborts the counter process.
n
At
abort function
the counter starts counting with the
load value
after gate restart.
