condition, before signal characterization (L_TYPE)
or filtering (PV_FTIME).

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 attribute. 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.

Linear: 0%
Square root: 10%
LOW_CUT
Limit used in square root processing. A value of
zero percent of scale is used in block processing if
the transducer value falls below this limit, in % of
scale. This feature may be used to eliminate noise
near zero for a flow sensor.

L_TYPE
Determines if the values passed by the transducer
block to the AI block may be used directly (Direct)
or if the value is in different units and must be
converted linearly (Indirect), or with square root (Ind
Sqr Root), using the input range defined by the
transducer and the associated output range.
