Operating time counter
The operating time counter will count how long a selected binary input or one
of the digital signals is closed (set). The time can be displayed in sec, min, hr
or days.
2.5.1 Reporting period of the counts
After an adjustable time (reporting period), the counts are stored for all
counters/integrators/operating time counters. The counts for the current and
the previous 7 completed reporting periods will be displayed. The following
counter/integrator types are possible:
- periodic
In addition, the time period (between 1 min and 12 hrs) must be selected in
the parameter Period.
- external
In this case, the counter/integrator is updated only when the selected
control signal is active (e.g. binary input is closed). When the control signal
is deactivated (e.g. binary input is opened), the counter/integrator value is
saved and reset to 0.
- daily
- weekly
- monthly
- yearly
- total
- daily, from ... to
The period also has to be selected, by means of the parameters “Daily start
time” and “Daily end time”. The counter/integrator will then be updated
from the start time only. When the end time has been reached, the counter/
integrator value is saved and reset to 0.
2.5.2 Resetting the counters / integrators / operating time counters
Periodic reset There is a reporting period for each counter/integrator/operating time counter.
At the end of this period, the current data (value and time) are saved and the
value reset to 0. Subsequently, the next period can be recorded.
An exception is the totalizer/integrator. It is saved whenever any count/
integration has been completed, but it is not reset to 0. It enables the totalizer
to be evaluated in the evaluation software PCA as well.
