1. Method for controlling the operation of an aseptic product filling machine, the operation comprising:

  • a pre-production phase in which sterilization, filling and closing stations of the machine are sterilized, and a production phase in which a sterilization, filling and closing of a plurality of holders takes place at the respective stations,in which, during the operation, control parameters of the stations are monitored for remaining in a pre-defined range,in which the monitoring comprises a measuring of the control parameters by means of sensors, a diagnosing of the measured control parameters and a storing of the measured control parameters, andin which the control parameters have been classified into a category of supercritical and a category of subcritical control parameters,wherein the method for the controlling of the operation comprises the steps of;

    performing a pre-production test procedure during the pre-production phase in which at least the subcritical control parameters are measured, diagnosed and stored;

    checking if the subcritical control parameters are within their range;

    starting the production phase if all of the subcritical control parameters are indeed within their range; and

    measuring, diagnosing and storing the supercritical control parameters and not the subcritical control parameters during the production phase.
