 LOW_CUT 
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.

 FIELD_VAL
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).
 UPDATE_EVT
This alert is generated by any change to the static data
 BLOCK_ALM
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.
 ALARM_SUM
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.
