O/S
The high and low scale values, engineering units
code, and number of digits to the right of the decimal
point used with the value obtained from the
transducer for a specified channel.

SIMULATE Disable
AUTO
Allows the transducer analog input or output to the
block to be manually supplied when simulate is
enabled. When simulation is disabled, the simulate
value and status track the actual value and status.

–
The revision level of the static data associated with
the function block. The revision value will be
incremented each time a static parameter value in
the block is changed.

–
This parameter reflects the error status associated
with the hardware or software components
associated with a block. It is a bit string, so that
multiple errors may be shown.

L_TYPE
AI1:

order
AI2 to AI5:
Direct
MAN
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.
