5.6.6.4 Additional functions counter 3
5.6.6.4.1 HW gate via Gate 3
Counter 3:
SW gate HW gate
Edge 0-1 de-activated
Edge 0-1 de-activated
Edge 0-1 1
1 Edge 0-1
Edge 0-1 1
1 Edge 0-1
Counter 3 - count once
If the internal gate has been closed automatically it may only be opened again under the following conditions:
SW gate
1
Edge 0-1 (after edge 0-1 at HW gate)
5.6.6.4.2 Latch function
Function

Exclusively counter 3 has the following additional functions:
n HW gate via Gate 3
n Latch function
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.

As soon as during a count process an edge 0-1 is recognized at the "Latch" input of
n
counter 3, the current counter value is stored in the according latch register.
n You may access the latch value via the parameter LATCHVAL of SFB 47.
n A just in LATCHVAL loaded value remains after a STOP-RUN transition.
