1. A computer based interactive method of controlling a plastics injection molding machine during input of portions of a production sequence and configuration of an injection cycle, which is effected essentially before the onset of the injection molding process, wherein, for a mold guided by the operator, the operating parameters required for the process sequence are input by way of an input unit into a computer based control unit storing these operating parameters and subsequently one or a plurality of injection cycles are implemented according to the stored operating parameters, the method comprising:

  • determining with the control unit a physically possible production sequence as well as a production sequence that is structurally specific to the machine and the tool employed, including peripheral devices associated therewith; and

    providing to an operator, with the control unit, a selection of possible inputs of further portions of the production sequence that can be added to the existing portions and are compatible with the machine and the tool, based on the determining step.
