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, 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
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 5-79.
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.
Data Type: DS-66
The primary discrete value calculated as a
result of executing the function.
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.
