ABSTRACT:
A control system for injection molding machines comprises a central control unit (26) for executing cyclical machine program sequences. Further, a visualization means (24, 25) is connected with the central control unit (26). The central control unit (26) has connected therewith, via an input/output means (16), an injection molding machine (18). According to the invention, an additional control unit (28) for cycle-independent processing of time-critical control steps is arranged independently of the central control unit (26) and is adapted for reducing the error-proneness. The additional control unit (28) is in particular an FPGA control unit.
