After an adjustable time period (reporting period) the counts are stored for all
counters/integrators/timers. The counts of the most recently concluded re-
porting period can be graphically displayed. The following counter/integrator
types are possible:
- periodic
The time period (between 1 min and 12 hrs) must additionally be selected in
the parameter Period.
- external
The counter/integrator is updated here only when the selected operating
signal is active (e.g. logic input is closed). When the operating signal is de-
activated (e.g. logic input is open), the counter/integrator value is stored
and reset to 0.
- daily
- weekly
- monthly
- yearly
- total
- daily from-to
In addition, the period 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 stored and reset to 0.
There is a reporting period for each counter/integrator/timer. At the end of this
period, the current data (value and time) are stored and the value is reset to 0.
Subsequently, the next period can be recorded.
An exception is the totalizer/integrator value. It is stored whenever any count/
integration has been completed, but it is not reset to 0. This enables the total-
izer to be evaluated also in the PCA evaluation software.
You can configure an operating signal for all 6 channels together, with the re-
sult that the counters/integrators are reset to 0 without storing the previous
values. The period for the counter/integrator summation will be restarted at
this point. This means that after the test run of an installation, for instance, the
recording can be freshly started, thereby eliminating the test run values, which
are not required.
v See "Reset generation" on page 59.
Another option of resetting the counter/integrator values is provided at the pa-
rameter level. After entering the password, you can define a value for each of
the 6 channels. The counter/integrator will then be set to this value. When, af-
ter editing, a value is accepted, a message with the new and the old count is
entered in the event list.
