The activation respectively de-activation of a counter happens via an
internal gate (I-gate). The I-gate consists of a software gate (SW
-
gate) and a hardware gate (HW-gate). The SW-gate is opened (acti-
vated) via your user application by setting the output status bit 2 for
the according counter. The SW-gate is closed (de-activated) by set-
ting the output status bit 10. The HW-gate is controlled via the digital
Gate
x
input. The parametrization allows you to de-activate the consid-
eration of the HW-gate so that the counter activation can take place
only via the SW-gate. The following states influence the I-gate:
SW-gate HW-gate influences the
I-gate
0 with edge 0-1 0
1 with edge 0-1 1
with edge 0-1 1 1
with edge 0-1 0 0
with edge 0-1 de-activated 1
Gate function abort and interrupt
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.
