Description
HI_HI_PRI R/W
Priority of the high high alarm that specifies the behavior if
OUT
reaches
HI_HI_LIM. The following values are valid:
0
exceeding of high high limit isn’t been evaluated
1
exceeding of high high limit is been evaluated, but
acknowledgement isn’t necessary
2-7
exceeding of high high limit is been evaluated and reported
according to the given priority (2 = low priority, 7 = high
priority).
Status of OUT changes to Good(NC):
UnackAdvisoryAlarmHighLimited.
8-15
exceeding of high high limit is been evaluated and reported
according to the given priority (2 = low priority, 7 = high
priority).
Status of OUT changes to Good(NC):
UnackCriticalAlarmHighLimited.
HI_LIM R/W
The limit value in engineering units as of the
HI_ALM
is active (with subject
to
HI_PRI
).

HI_PRI, HI_LIM
HI_PRI R/W
Priority of the high alarm that specifies the behavior if
OUT
reaches HI_LIM.
The following values are valid:
0
exceeding of high limit isn’t been evaluated
1
exceeding of high limit is been evaluated, but
acknowledgement isn’t necessary
2-7
exceeding of high limit is been evaluated and reported
according to the given priority (2 = low priority, 7 = high
priority).
Status of OUT changes to
Good(NC):UnackAdvisoryAlarmHighLimited.
8-16
exceeding of high limit is been evaluated and reported
according to the given priority (2 = low priority, 7 = high
priority).
Status of OUT changes to
Good(NC):UnackCriticalAlarmHighLimited.
IO_OPTS R/W
Options which the user may select to alter input and output processing of the
Analog Input Block. The following option is supported by this block:
Low cutoff
The Analog Input low cutoff algorithm is enabled, i.e. if
PV
is
less
than
LOW_CUT
,
PV
is set to ‘0.0’
see also:
LOW_CUT
L_TYPE R/W
Determines how the values, passed by the Transducer Block to the Analog
Input Block, may be used. The following settings are valid:
Direct
values are used directly
Indirect
values are in different units and must be converted
Indirect square root values are in different units and must be converted
with square root.
The conversion in case of ‘Indirect’ and ‘Indirect square root’ is
determined by parameters
XD_SCALE
and
OUT_SCALE
(see for
details).

XD:SCALE, OUT_SCALE
LO_ALM R
With subject to the setting of
LO_PRI
, LO_ALM shows details about the high
alarm as acknowledge state and time stamp. See
LO_PRI
for details.
