Parameters Description Range of values Default
Pulse duration With the setting "Characteristics of
the output: Pulse at comparison
value" the pulse duration of the output
signal may be specified. Only even
values are possible. The value is
internal multiplied with 1.024ms.
0 to 510 0
Hardware inter-
rupt: Hardware
gate opening
In the activated state a hardware
interrupt is generated when the hard-
ware gate opens while the software
gate is open.
n activated
n deactivated
Hardware inter-
rupt: Hardware
gate closing
In the activated state a hardware
interrupt is generated when the hard-
ware gate closes while the software
gate is open.
n activated
n deactivated
deactivated
Hardware inter-
rupt: On reaching
comparator
In the activated state a hardware
interrupt is triggered on reaching the
comparator (reaction) value.
The process interrupt may only be
released if in addition the value of
"Characteristics of the output" is not
"no comparison".
n activated
n deactivated
deactivated
Hardware inter-
rupt: Overflow
In the activated state a hardware
interrupt is generated in the event of
an overflow (exceeding the upper
count limit).
n activated
n deactivated
deactivated
Hardware inter-
rupt: Underflow
In the activated state a hardware
interrupt is generated in the event of
an underflow (undershooting the
lower count limit).
n activated
n deactivated
deactivated
6.5.2 SFB 47 - COUNT - Counter controlling
The SFB 47 is a specially developed block for the VIPA CPU for con-
trolling of the counters. The SFB is to be called with the corre-
sponding instance DB. Here the parameters of the SFB are stored.
With the SFB COUNT (SFB 47) you have following functional options:
n Start/Stop the counter via software gate SW_GATE
n Enable/control digital output DO
n Read the status bit
n Read the actual count and latch value
n Request to read/write internal counter registers
