OUT (Process, Scaling, Tuning)
The current output value of the block.
OUT_D (Process)
The current output value of a discrete block.
OUT_HI_LIM (Limiting)
A limit for the maximum output value from a block in modes other than
manual.
OUT_LO_LIM (Limiting)
A limit for the minimum output value from a block in modes other than
manual.
OUT_SCALE (Scaling)
The scaling parameter used for the output parameter.
OUT_STATE (Process)
Index to the text description of the discrete output state.
PV (Process, Scaling, Tuning)
The process variable, or primary variable for this block. For AI and control
blocks such as PID, this represents a measurement of the state of the
process (such as temperature or level). For AO blocks, the process variable
is the current setpoint of the block.
Table B-9. OUT_SCALE Parameter
Subfield Meaning
EU_100 Engineering units value at 100 percent of scale.
EU_0 Engineering units value at zero percent of scale.
UNIT_INDEX Actual engineering units code (such as mA).
DECIMAL Number of digits a host shows to the right of the decimal for display
purposes.
