Description
Used only for Autotuning. Sign of the process gain
(Delta PV1/Delta CV1).
• Set to indicate a negative process gain
(increase in output causes a decrease in PV1).
• Reset to indicate a positive process gain
(increase in output causes an increase in P1V).
Used only for Autotuning. Sign of the process gain
(Delta PV1/Delta CV2).
• Set to indicate a negative process gain
(increase in output causes a decrease in PV1).
• Reset to indicate a positive process gain
(increase in output causes an increase in PV1).
Used only for Autotuning. Sign of the process gain
(Delta PV1/Delta CV3).
• Set to indicate a negative process gain
(increase in output causes a decrease in PV1).
• Reset to indicate a positive process gain
(increase in output causes an increase in PV1).
Used only for Autotuning. Sign of the process gain
(Delta PV2/Delta CV1).
• Set to indicate a negative process gain
(increase in output causes a decrease in PV2).
• Reset to indicate a positive process gain
(increase in output causes an increase in PV2).

Process type selection for both PV1 and PV2
(1=Integrating, 0=non-integrating)
The internal model gain parameter for CV1 - PV1.
Enter a positive or negative gain depending on
process direction.
If CV1PV1ModelGain = INF or NAN, set bit in
Status.
The internal model gain parameter for CV2 - PV1.
Enter a positive or negative gain depending on
process direction.
If CV2PV1ModelGain = INF or NAN, set bit in
Status.
