Range Initial Value Description
Static Revision
ST_REV
1 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.
Tag Description
TAG_DESC
2 RW ALL 7 bit ASCII Spaces
Data Type: Octet String
The user description of the intended
application of the block.
Strategy
STRATEGY
3 RW ALL 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
4 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.
Block Mode
MODE_BLK
5
Data Type: DS-69
Valid Bits: 7:OOS, 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
TARGET 5.1 RW ALL

3: Simulate Active
7: Input Failure / Bad PV
Status
14: Power-up
15: Out-of-Service
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. Multiple
errors may be shown, see table 4-80.
Process Value Discrete
PV_D
7 RO N/A
PV_D Status set equal to
Field_Val_D Status
Dynamic
Data Type: DS-66
The process variable used in block
execution. Value is converted from
Readback to show the actuator position in
the same units as the set point value.
Output Discrete
OUT_D
8
OOS
MAN
OUT_STATE
Data Type: DS-66
The primary discrete value calculated as a
result of executing the function.
Simulate Discrete
SIMULATE_D
9
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. SIMULATE_STATUS 9.1 ALL 0
SIMULATE_VALUE 9.2 ALL 0
TRANSDUCER_STATUS 9.3 RO ALL 0
TRANSDUCER_VALUE 9.4 RO ALL 0
