RO
N/A
0 to 65535
0
Data Type: Unsigned16
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.

Data Type: Octet String
The user description of the intended application of
the block.

0 to 65535
0
Data Type: Unsigned16
The strategy field can be used to identify grouping
of blocks. This data is not checked or processed
by the block.
Alert Key
ALERT_KEY

RW
ALL
1 to 255
0
Data Type: Unsigned8
The identification number of the plant unit. This
information may be used in the host for sorting
alarms, etc.

Valid Bits: 7: OOS, 5: LO, 4: MAN, 3: AUTO
2: CAS, 1: RCAS
The actual, target, permitted, and normal modes of
the block.
Target: The requested block mode
Actual: The current mode of the block
Permitted: Allowed modes for Target
Normal: Most common mode for Target

Dynamic
Data Type: Bit String
0=Inactive
1=Active
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.

Data Type: DS-83
Allows the transducer discrete 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.
