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.
In a glassware forming machine of the type including a plurality of machine sections each having a set of machine components for receiving gobs of molten glass and molding the glass into glassware articles, said sections operating in phased relationship within cycles of operation,
For use with an electronic control system for a glassware forming machine, said forming machine including a plurality of machine sections each section having a plurality of machine components operating in phased relationship within a machine cycle for receiving molten glass and molding glassware articles therewith, said control system including at least one section controller for producing timing signals representing actuating and deactuating times of machine components of at least one section of said forming machine, and a machine controller for providing set-up information for said machine components,
