Abstract: A control system is disclosed for controlling a glassware molding machine having a number of forming sections, each for successively forming a number of glass articles. The control system has a number of automatisms for controlling respective actuating mechanisms of the machine, which cooperate to form the glass articles; and a central control unit connected individually to the automatisms and having a processing unit configured to control and coordinate activation of the actuating mechanisms of the automatisms. The processing unit is configured to determine the activation times of the actuating mechanisms of the automatisms on the basis of a desired production plan, and to transmit corresponding control signals to the automatisms.
