A3257−2.0 en/de/fr
Measures the time span between two edges on digital in-
The duration of a periodic signal can also be measured.
It is output in ms, s or as a frequency 1/s.
Time resolution: Equals 1/ calculation rate (see above),
Default 1/19200 = 52 s
Maximum time that can be measured: 1/calculation rate *
Default approx. 436s
Start digital input: Starts time span measurement
Stop digital input: Stops time span measurement
If start and stop criterion (input, edge) are identical, the
period duration is measured. Otherwise the pulse length is
out0 Comprises the pulse duration in s (or ms) or the fre-
Start falling edge (startFallEdge):
- true: Start on falling edge
- false: Start on rising edge
Stop falling edge (startFallEdge):
- true: Stop on falling edge
- false: Stop on rising edge
Restult type (resultType):
0: pulse width in s is output
1: pulse width in ms is output
2: frequency in Hz is output.
Recommended for periodic signals only.
Start digital input: invalid
Stop digital input: invalid
Start falling edge: false
Stop falling edge: false Frequency: false
Result type: 0 (pulse width in s)
If the pulse or period length is greater than the maximum
time, measurement is stopped, the output is marked as
invalid and the start criterion is waited for.
