Initial value: All limits are set to plus or minus infinity (+INF or -INF), which is the same as no limit. IEEE 754-1985 defines the

floating point representation of plus and minus infinity.

Raw value of the field device in percent of thePV range,
with a status reflecting the Transducer condition, before
signal characterization (L_TYPE), filtering (PV_FTIME), or
low cut (LOW_CUT).

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.

The current alert status, unacknowledged states,
unreported states, and disabled states of the alarms
associated with the function block.

Selection of whether alarms associated with the block will
be automatically acknowledged.
Amount the PV must return within the alarm limits before
the alarm condition clears. Alarm Hysteresis is expressed
as a percent of the PV span. 0 to 50

The status of the low low alarm and its associated time
stamp.

This alert is generated by any change to the static data

Sets low cut point of output. This low cut value become
available by setting "Low cutoff" to "IO-OPTS".

Time constant of a single exponential filter for the PV, in
seconds.
