CtrlParamsBackUp
.Cool.DWeighting
REAL 1.0 Saved derivative action weighting factor for cooling
CtrlParamsBackUp.Cool.Cycle REAL 1.0 Saved sampling time of the PID algorithm for cooling in
seconds
CtrlParamsBackUp
.Cool.ControlZone

PIDSelfTune.SUT.Calculate-
ParamsHeat
BOOL FALSE The properties of the heating branch of the controlled
system are saved during pretuning for heating. If
SUT.CalculateParamsHeat = TRUE, the PID parameters
for heating (Retain.CtrlParams.Heat structure) are recalcu-
lated on the basis of these properties. This enables you to
change the parameter calculation method (PIDSelf-
Tune.SUT.TuneRuleHeat parameter) without having to
repeat the tuning.
SUT.CalculateParamsHeat is set to FALSE after the cal-
culation.
Only possible if the pretuning was successful
(SUT.ProcParHeatOk = TRUE).
PIDSelfTune.SUT.Calculate-
ParamsCool
BOOL FALSE The properties of the cooling branch of the controlled
system are saved during tuning for cooling. If
SUT.CalculateParamsCool = TRUE, the PID parameters
for cooling (Retain.CtrlParams.Cool structure) are recalcu-
lated on the basis of these properties. This enables you to
change the parameter calculation method (PIDSelf-
Tune.SUT.TuneRuleCool parameter) without having to
repeat the tuning.
SUT.CalculateParamsCool is set to FALSE after the cal-
culation.
Only possible if the pretuning was successful
(SUT.ProcParCoolOk = TRUE).
Only effective if Config.ActivateCooling = TRUE and Con-
fig
.AdvancedCooling = TRUE.
