Configure CC Function Block tuner
Follow these steps to configure the tuner.
To configure the CC Function Block tuner
- Put all three CV parameters into Manual mode.
- Set the AtuneStart parameter. The tuner starts collecting PV and CV data for noise calculation.
- After collecting 60 samples (60*DeltaT) period, the tuner adds StepSize to the CV.
- Set the AtuneUseModel parameter to copy the tuned parameters to the model parameters. The function block then resets the AtuneUseModel parameter.TIP:
- After successfully collecting the PV data as a result of the CV step change, the CV assumes its value before the step change and the AtuneStatus, GainTuned, TCTuned, DTTuned, and RespTCTuned parameters are updated.
- After a successful AutoTuneDone, the Atune parameter is set to one (1). Tuning completed successfully.
- To identify models and to calculate response time constants for all three CV-PV processes, run the tuner up to three times to obtain CV1-PV, CV2-PV, and CV3-PV models and tuning, respectively.
