ABSTRACT:
An improved electronic control system for glassware forming apparatus having a heirarchy of machine level supervisory controllers (including a machine controller and an operator communications controller), section controllers, and individual mechanism controllers. The mechanism controllers may be dedicated to the control of a variety of functions admitting of automated control, such as servo-control of electrical motors, sequencing of solenoid valves, generating alarm signals, etc. The mechanism controllers include separate control programs designed for their associated forming mechanisms, and are subject to on-off timing control in real time from the section level controllers. In general, the machine controller and operator I/O controller handle set-up, operator modifications during operation, and other "non-real-time"interactions with the mechanism controllers; the machine controller also coordinates the operation of a plurality of mechanism controllers in accordance with machine-level parameters.
