Parameter Access 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).
see also: 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).
see also: 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.
