How the CPU should react at opening of the SW gate may be set with the
parameter
Gate function
. The usage of the HW gate may be determined by
the parameter
Hardware gate
.
Gate control via SW gate, canceling
(HW gate deactivated, gate function: Cancel count)
SW gate HW gate Reaction Counter
edge 0-1 de-activated Restart with load value
Gate control via SW gate, stopping
(HW gate deactivated, gate function: Stop count)
SW gate HW gate Reaction Counter
edge 0-1 de-activated Continue
Gate control via SW/HW gate, canceling
(HW gate activated, gate function: Cancel count)
SW gate HW gate Reaction Counter
edge 0-1 1 Continue
1 edge 0-1 Restart with load value
Gate control via SW/HW gate, stopping
(HW gate activated, gate function: Stop count)
SW gate HW gate Reaction Counter
edge 0-1 1 Continue
1 edge 0-1 Continue
Gate control via SW/HW gate, operating mode "Count once"
If the internal gate has been closed automatically it may only be opened
again under the following conditions:
SW gate HW gate Reaction I gate
1 edge 0-1 1
edge 0-1
(after edge 0-1 at HW
gate)
edge 0-1 1
As soon as during a count process an edge 0-1 is recognized at the
"Latch" input of a counter, the recent counter value is stored in the
according latch register.
The latch value may be accessed by the parameter LATCHVAL of the
SFB 47.
A just in LATCHVAL loaded value remains after a STOP-RUN transition.
