MMC Function Block Tuning Procedure

Follow these steps to configure the tuner.
To configure the tuner
  1. Put all three CV parameters into Manual mode.
  2. Set the appropriate AtuneStart parameter.
    The tuner starts collecting PV and CV data for noise calculation.
  3. After collecting 60 samples (60*DeltaT) period, the tuner adds StepSize to the CV.
    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.
  4. Set the appropriate AtuneUseModel parameter to copy the tuned parameters to the model parameters
    The function block then resets the AtuneUseModel parameter.
    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 six CV - PV processes, run the tuner up to three times to obtain CV1 - PV2, CV2 - PV2, and CV3 - PV2 models and tuning, respectively. After each run, two process models are identified: CV - PV1 and CV - PV2 (two process variables respond as a result of one CV step change).
