Pulse counters
All digital inputs can be operated with a frequency of
25 Hz. Here, the pulse duration and the pulse interval
must be greater than 20 ms. The typical pulse duration
for S0 pulses is 30 ms.
The maximum number of pulses per hour is based on
the minimum pulse duration and the minimum pulse
interval:
Pulse duration
> 20 ms
Pulse interval
> 20 ms

The pulse counters can be configured with
a simultaneous measurement value or power calculation.
The pulses are counted as 64-bit numbers and overflow
after approximately 1.17 x 10
10
years of continuous
operation (25 Hz).
Pulse value:
A pulse value can be assigned to each digital input.
Use the impulse value to specify the measurement value
or power value (e.g. energy) to which a pulse should
correspond.
Measurement value calculation:
Power value calculation:
Measurement value = pulse x pulse value
Power value =
pulse x pulse value
