The Temperature Control package in AC500 V3 library uses a state machine to accomplish all work , including:

  • Automatic PID control (state PID_Process): Normalbetrieb

  • Auto tuning procedure (state AutoTune): Can be used during the commissioning phase to calculate the optimized parameters for PID controller.

  • Manual Control (state Manual): Open loop control with directly change of duty cycle.

  • Handhabung von Alarmen

The figure below explains the statemachine of temperature control for one temperature zone.
