LO_LO_PRI
Priority of the low low alarm.

LO_PRI
Priority of the low alarm.

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.

MANUFAC_ID
Manufacturer identification number — used by an interface device to locate the DD file for the
resource.

MAX_NOTIFY
Maximum number of unconfirmed notify messages possible.

MEMORY_SIZE
Available configuration memory in the empty resource. To be checked before attempting a download.

MIN_CYCLE_T
Time duration of the shortest cycle interval of which the resource is capable.

MODE_BLK
The actual, target, permitted, and normal modes of the block.

NV_CYCLE_T
Minimum time interval specified by the manufacturer for writing copies of NV parameters to non-
volatile memory. Zero means it will never be automatically copied. At the end of NV_CYCLE_TIME,
only those parameters which have changed (as defined by the manufacturer) need to be updated in
NVRAM.

OUT
The primary analog value calculated as a result of executing the function.

OUT_D
The primary discrete value calculated as a result of executing the function.

OUT_HI_LIM
Limits the maximum output value.

OUT_LO_LIM
Limits the minimum output value.

OUT_SCALE
The high and low scale values, engineering units code, and number of digits to the right of the
decimal point to be used in displaying the OUT parameter and parameters which have the same
scaling as OUT.

OUT_STATE
Index to the text describing the states of a discrete output.

PV
Either the primary analog value for use in executing the function, or a process value associated with
it. May also be calculated from the READBACK value of an AO block.
