Data Type: DS‐69
Valid Bits: 7: OOS, 5: LO, 4: MAN, 3: AUTO

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.
Process Value Discrete
PV_D
7 RO N/A
PV_D Status set equal
to Readback_D Status
Dynamic
Data Type: DS‐66
The discrete process variable calculated from
READBACK_D.

PV_STATE
Data Type: DS‐66
The discrete target block output value (set point).
Output Discrete
OUT_D
9 MAN OUT_STATE
Data Type: DS‐66
Position target of valve. 0=closed, 1=open, 2-100
position the value in 5% steps.
Simulate Discrete
SIMULATE_D
10
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.
