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.
