Description
LO_LIM R/W
The limit value in engineering units as of the
LO_ALM
is active (with subject
to
LO_PRI
).
see also:
LO_PRI, LO_LAM
LO_LO_ALM R
With subject to the setting of
LO_LO_PRI
, LO_LO_ALM shows details about
the high alarm as acknowledge state and time stamp. See
LO_LO_PRI
for
details.

LO_LO_PRI, LO_LO_LIM
LO_LO_LIM R/W
The limit value in engineering units as of the
LO_LO_ALM
is active (with
subject to
LO_LO_PRI
).
see also:
LO_LO_PRI, LO_LO_LAM
LO_LO_PRI R/W
Priority of the low alarm that specifies the behavior if
OUT
reaches
LO_LO_LIM. The following values are valid:
0
exceeding of low limit isn’t been evaluated
1
exceeding of low limit is been evaluated, but
acknowledgement isn’t necessary
2-7
exceeding of low limit is been evaluted and reported
according to the given priority (2 = low priority, 7 = high
priority).
Status of OUT changes to
Good(NC):UnackAdvisoryAlarm:LowLimited.
8-17
exceeding of low limit is been evaluated and reported
according to the given priority (2 = low priority, 7 = high
priority).
Status of OUT changes to Good(NC):
UnackCriticalAlarm:LowLimited.
LO_PRI R/W
Priority of the low low alarm that specifies the behavior if
OUT
reaches
LO_LIM
. The following values are valid:
0
exceeding of low low limit isn’t been evaluated
1
exceeding of low low limit is been evaluated, but
acknowledgement isn’t necessary
2-7
exceeding of low low limit is been evaluted and reported
according to the given priority (2 = low priority, 7 = high
priority).
Status of OUT changes to
Good(NC):UnackAdvisoryAlarm:LowLimited.
8-18
exceeding of low low limit is been evaluated and reported
according to the given priority (2 = low priority, 7 = high
priority).
Status of OUT changes to
Good(NC):UnackCriticalAlarm:LowLimited.
LOW_CUT R/W
Limit used if option
‘Low cutoff’
is set (see
IO_OPTS
for details). A value of
zero percent of scale is used in block processing if the transducer value falls
below the LOW_CUT limit. This feature may be used to eliminate noise near
zero for a flow sensor.
