Description
Module update period for Real Time Sampling
mode.
Module time stamp value for Real Time Sampling
mode.
PV1 tuning limit scaled in the PV1 units. When
Autotune is running and predicted PV1 exceeds
this limit, the tuning will be aborted.
PV2 tuning limit scaled in the PV2 units. When
Autotune is running and predicted PV2 exceeds
this limit, the tuning will be aborted.
Maximum time in minutes for PV1 autotune to
complete following the CV1 step change. When
PV1 autotune exceeds this time, tuning will be
aborted.
Maximum time in minutes for PV2 autotune to
complete following the CV2 step change. When
PV2 autotune exceeds this time, tuning will be
aborted.
An estimate of the noise level expected on the
PV1 to compensate for it during tuning.
The selections are: 0=low, 1=medium, 2=high
An estimate of the noise level expected on the
PV2 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.
Desired speed of closed loop response for CV1 -
PV1.
• Slow response: ResponseSpeed=0
• Medium response: ResponseSpeed=1
• Fast response: ResponseSpeed=2
If ResponseSpeed is less than 0, Slow response is
used. If ResponseSpeed is greater than 2, Fast
response is used.
