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).

_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.
