Information on this block such as Block Tag, DD Revision,
Execution Time etc.
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.
The user description of the intended application of the
block.
The strategy field can be used to identify grouping of
blocks. This data is not checked or processed by the
block.
The identification number of the plant unit. This
information may be used in the host for sorting alarms,
etc.
The actual, target, permitted, and normal modes of the
block.
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.
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.
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.
1=Disabled, 2=Active
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.
The primary analog value calculated as a result of
executing the function.
Options for controlling access of host computers and local
control panels to operating, tuning and alarm parameters
of the block.
Options which the user may select to alter input and
output block processing. bit 6: Low cutoff
Options which the user may select in the block processing
of status. bit 3: Propagate Failure Forward, bit 8: Uncertain
if Man mode.
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.

O/S
O/S
O/S Used to select a transducer block to connect to. In the
case of the AV550G, an averaging oxygen
concentration a, b and c signals are always set for the
AI1, AI2 and AI3 blocks, respectively.
Determines if the values passed by the transducer block to
the AI block may be used directly (Direct (1)) or if the
value is in different units and must be converted linearly
(Indirect (2)), or with square root (Ind Sqr Root (3)), using
the input range defined by the transducer and the
associated output range. "Indirect Square Root" is not
used for the AV550G.
