Abstract
Apparatus and method for controlling an injection molding system having a plurality of devices which generate a corresponding plurality of feedback signals includes structure and steps for providing an operator control station which has a display and at least one operator input device. A single, general-purpose computer is coupled to both the operator control panel and the plurality of injection molding devices and functions to perform multiple-tasking control of both the injection molding functions and the operator control functions. The computer preferably performs real-time closed loop control of the plurality of injection molding devices while also processing system feedback signals and operator input signals. Thus, there is no need for the analog signal processor and the programmable logic controller of the prior art. Preferably, the single general purpose computer has local area network and internet connections to allow external control and feedback of the operating parameters of the injection molding system.
