7.5 Counting Functions
7.5.1 Count Pulses
The
Count pulses
function has three Boolean inputs and one
numerical output. If the
Counting
input has the value "1", then the
change from "0" to "1" at the
Pulses
input will be counted and the
count value will be set at the output. If the
Reset
input is at "1", then
the count value, and thus the output as well, will be "0".
Flexible counting structures can thus be obtained by placing the
Pulse generation
function upstream (see Chap. 7.8.5). The
placement of a downstream
Note value
function (see Chap. 7.4.6)
makes it possible to also implement a counter with an interim status.

7.5.2 Stop Clock
The
Stop clock
function has two Boolean inputs and one numerical
output. If the
Start/Stop
input has the value "1", then the seconds will
be counted and the time will be set at the output. If the
Reset
input is
at "1", then the time, and thus the output as well, will be "0".
The behavior at the output can be controlled with the
Output
parameter.
Two settings are possible:
Current time
The output value is the current number of seconds counted.
Stopped time
The output value is not the current quantity, but rather the most
recently measured quantity. This means that the current count is set
to the output whenever the time is stopped with the
Start/Stop
input.
Flexible time measurement structures can thus be obtained by
placing the
Pulse generation
function upstream (see Chap. 7.8.5).
