Description
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.
Data Type: Unsigned16
The strategy field can be used to identify
grouping of blocks. This data is not checked or
processed by the block.
Data Type: Unsigned8
The identification number of the plant unit. This
information may be used in the host for sorting
alarms, etc.
Data Type: DS‐69
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
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‐66
The discrete process variable calculated from
READBACK_D.
Data Type: DS‐66
The discrete target block output value (set
point).
Data Type: DS‐66
Position target of valve. 0=closed, 1=open,
2-100 position the value in 5% steps.
