Block Tag Information on this block such as Block Tag, DD
= O/S 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.
AUTO The user description of the intended application of
the block.
AUTO The strategy field can be used to identify grouping
of blocks. This data is not checked or processed by
the block.
AUTO The identification number of the plant unit. This
information may be used in the host for sorting
alarms, etc.
AUTO 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.
Value = The primary analog value calculated as a result of
MAN executing the function.
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.
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. Refer to Table
5.15 for the unit available.
O/S 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.
AUTO Options for controlling access of host computers
and local control panels to operating, tuning and
alarm parameters of the block.
O/S Options which the user may select to alter input and
output block processing
