Parameter Access Description
TIME_UNIT1 R/W
TIME_UNIT_1 specifies the time unit of IN_1, if IN_1 comes from a pulse
input block (i.e. ‘Input 1 accumulate‘ is set in INTEG_OPTS) and converts
the input IN_1 according to one of the following time unit:
s second
min minute
h hour
d day
TIME_UNIT2 R/W
TIME_UNIT_2 specifies the time unit of IN_2, if IN_2 comes from a pulse
input block (i.e. ‘Input 2 accumulate‘ is set in INTEG_OPTS) and converts
the input IN_2 according to one of the following time unit:
s second
min minute
h hour
d day
TOTAL_SP R/W
Setpoint for batch totalization. Meaning depends on the chosen type of
integration. (see INTEG_TYPE for details).
see also: INTEG_TYPE
UNCERT_LIM R/W
UNCERT_LIM specifies the limit for Uncertain status of parameter OUT. If
PCT_INCL gets below this limit, the status of parameter OUT turns from
Uncertain to BAD (unless GOOD_LIM equals UNCERT_LIM):
UNCERT_LIM
≤ PCT_INCL ⇒ OUT.status = Uncertain
PCT_INCL < UNCERT_LIM ⇒ OUT.status = BAD
see also: GOOD_LIM
UNIT_CONV R/W
UNIT_CONV is used as a factor to convert the engineering units of IN_2 into
the engineering units of IN_1, after IN_2 was converted according to it's time
unit.
This is only true, if IN_2 is connected to another output parameter!
NOTE:
This is necessary since in the integration process, the (converted) inputs
IN_1 and IN_2 are added which presupposes a common unit base.
UPDATE_EVT R
Alert generated by a change to static data. The subfields of this parameter
give detailed information about the changed static parameter, time of change
and state of the update event.
