Open circuit detection
A [
} 134]
An open circuit on track A is indicated in index
0x6000:07 [ } 141] and as process data. Diagnosis is
only possible if the corresponding input is wired differ-
entially. A differential voltage < 3.5 V (typical, subject
to change) is detected as a broken wire.

Frequency window
[
}
132]
This is the minimum time over which the frequency is
determined. Default 10 ms [resolution: 1 µs]
The number of pulses in the time the follow-
ing is measured. The maximum waiting time is speci-
fied in the "Frequency Wait Time" parameter. The
number of pulses is divided by the actual time window
size. The determined frequency is output in index
0x6000:13 [
}
141] and as a process data.
The frequency calculation is carried out locally without
distributed clocks function.

Frequency scaling
[
} 132]
Scaling of the frequency measurement (must be di-
vided by this value to obtain the unit in Hz):
100: “0.01 Hz”

Period scaling [ } 132]
Resolution of the period in the process data:
100: “100 ns” period value is a multiple of 100 ns
500: “500 ns” period value is a multiple of 500 ns
