The percent of the value from the
Transducer block or from the
simulation value, when enabled,
before the characterisation (L_
TYPE) and Filtering (PV_FTIME).
This alert is generated by any change to the static data
The block alarm is used for all configuration, hardware, connection failure or system problems in the block. The cause of
the alert is entered in the subcode field. The first alert to become active will set the Active Status in the status parameter.
As soon as the Unreported status is cleared by the alert reporting task, another block alert may be reported without
clearing the Active Status, if the subcode has changed.
The summary alarm is used for all process alarm in the block. The cause of the alert is entered in the subcode field. The first
alert to become active will set the Active Status in the status parameter. As soon as the Unreported status is cleared by the
alert reporting task, another block alert may be reported without clearing the Actve Status, if the subcode has changed.
Used to set auto acknowledgment of the alarms

PV = CHANNEL_VALUE – To be used when XD_SCALE = OUT_SCALE
PV = FIELD_VAL% * (OUT_SCALE_100% - OUT_SCALE_0%) + OUT_SCALE_0%
To be used when XD_SCALE != OUT_SCALE
IF FIELD_VAL < 0.0 when PV = OUT_SCALE 0%
ELSE IF FIELD_VAL < LOW_CUT when PV = OUT_SCALE 0%
ELSE when PV = √ Field_Val% * (OUT_SCALE_100% - OUT_SCALE_0%) + OUT_SCALE_0%
Limit used in square root processing. A value of zero percent of scale is used in block
processing if the transducer falls below this limit, in % of scale. The features may be
used to eliminate noise near zero for a flow sensor.
Time constant of a single exponential filter for the PV, expressed in seconds. This is the
time necessary for reach the 63% of the variation in input.
Alarm Hysteresis is the amount the PV must return within the alarm limit before the
alarm condition clears.
Expressed in OUT_SCALE unit.
