Value
Data Type: Unsigned16
The revision level of the static data associated
0 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
Spaces The user description of the intended application of
the block.
Data Type: Unsigned16
The strategy field can be used to identify grouping
0
of blocks. This data is not checked or processed
by the block.
Data Type: Unsigned8
The identification number of the plant unit. This
0
information may be used in the host for sorting
alarms, etc.

Data Type: Bit String

This parameter reflects the error status
Dynamic
associated with the hardware or software
components associated with a block. It is a bit
string, so that multiple errors may be shown. See
table 5-23.
Data Type: DS-65
The process variable used in block execution.
Dynamic This value is converted from READBACK to show
the actuator position in the same units as the
setpoint value.
Data Type: DS-65
The SP of the analog block. Can be derived from
CAS_IN, RCAS_IN in normal modes, or can track
Dynamic PV in MAN or LO modes. IO_OPTS is used to
determine value of SP in MAN or LO. If no
IO_OPTS for SP tracking are set, SP will freeze
when mode changes from CAS or RCAS.
Data Type: DS-65
The primary value and status calculated by the
Dynamic
block in Auto mode. OUT may be set manually in
Man mode.

Description
Target: The requested block mode
Actual: The current mode of the block
(Note: Bit 6 (IMAN) is valid for ACTUAL only)
Permitted: Allowed modes for Target
Normal: Most common mode for Target
