HI_HI_LIM HI_HI_LIM HI_HI_LIM HI_HI_LIM
High High Limit
R/W The setting for High High Alarm in engineering units.
Setting range see in the following part.
NaN
HI_HI_PRI HI_HI_PRI HI_HI_PRI HI_HI_PRI
High High Priority
R/W Priority of the High High Alarm.
Setting see in the following part.

Setting range for previous 2
parameters:
x_y_LIM

-3.39 E38…+3.39 E38 / - INF (- infinite) / + INF (+ infinite)
Setting for previous 2
parameters:
x_y_PRI
x_y_Priority
0: The associated alert may clear when the priority is changed
to 0, but it will never occur.
1: The associated alert is not send as a notification. If the
priority is above 1, then the alert must be reported.
2: Reserved for alerts that do not require the attention of a
plant operator, e.g. diagnostic and system alerts. Block alarm,
error alarm and update event have a fixed priority of 2.
3...7: Increasing higher priorities - advisory alarms.
8...15: Increasing higher priorities - critical alarms.

IO_OPTS IO_OPTS IO_OPTS IO_OPTS
IO Options
(IO = Input/Output)
R/W Options which the user may select to alter input and output
block processing.

Setting:
Low Cutoff / Units Conversion
L_TYPE L_TYPE L_TYPE L_TYPE
Linearization Type
R/W Determines if the values passed by the TB 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.
W = Writeable only by setting "OOS" in MODE_BLK
Uninitialized
Setting:
Uninitialized / Direct / Indirect / Ind Sqr Root
