1. A control system for injection molding machines, comprising
a central control unit for executing cyclical machine program sequences,
a visualization means connected with the central control unit,
an input/output means connected with the central control unit and the injection molding machine, and
an additional control unit arranged independently of the central control unit, the additional control unit storing switching sequences in addition to the sequences stored in the central control unit and being adapted for cycle-independently processing time-critical control steps.
