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.
In the CPU a comparison value may be stored that is assigned to the digital output, to the
status bit "Status Comparator" STS_CMP and to the hardware interrupt. The digital
output may be activated depending on the count value and comparison value. A compar-
ison value may be entered by the parameter assignment screen form respectively by the
request interface of the SFB 47.
