Operator-Manual mode request for
CV3.
Set TRUE by the operator interface to
request Manual mode. The function
block resets this parameter to FALSE.
Reset Program control values.
When TRUE, the Prog_xxx_Req inputs
are reset to FALSE.
When TRUE and Program control, set
SPProg equal to SP and CVxProg equal
to CVx.
When ProgValueReset is TRUE, the
instruction sets this input to FALSE.
Selects Time Base Execution mode.
Value/Description
0 = Periodic mode
1 = Oversample mode
2 = Real time sampling mode
For more information about timing
modes, see Function Block Attributes.
Execution time for Oversample mode. Valid = 0...4194.303 seconds
Module update period for Real Time
Sampling mode.
Module time stamp value for Real
Time Sampling mode.
PV tuning limit scaled in the PV units.
When Autotune is running and
predicted PV exceeds this limit, the
tuning will be aborted.
Maximum time for autotune to
complete following the CV step
change. When autotune exceeds this
time, tuning will be aborted.
An estimate of the noise level
expected on the PV to compensate for
it during tuning.
The selections are: 0=low,
1=medium, 2=high
CV1 step size in percent for the tuning
step test. Step size is directly added to
CV1 subject to high/low limiting.
CV2 step size in percent for the tuning
step test. Step size is directly added to
CV2 subject to high/low limiting.
CV3 step size in percent for the tuning
step test. Step size is directly added to
CV3 subject to high/low limiting.
