S0 power values
Since the pulse interval may be very large, continual
calculation of the measurement or power values is not
possible. For this reason, only the mean values are
calculated. For measurement value calculation, the mean
values are calculated from the number of pulses per
period multiplied by the pulse value. For power value
calculation, this value must be divided by the amount of
time that can be set.
The period is assigned to the digital input and can be
set in a region of 1 to 60 minutes. After the period ends,
the value can be called via the Modbus.
For each digital input, an external synchronisation
can be triggered; in this case, a synchronisation pulse
completes one period and starts a new period. A fixed
capture period of 30 seconds is preset for external
synchronisation. If no synchronisation pulse exists after
the period expires, a maximum of 30 seconds is waited
and the software then carries out the synchronisation.
All further periods are synchronised by the software.
A period of 15 min is the factory setting.
The calculation result for the S0-power
value is not until the end of the cycle avail-
able.
