Abstract
A control system for the control of a multisection glassware forming machine in a manner which enables totally independent operation of any section regardless of the status of remaining sections. The control program for each section is stored in unalterable, read-only memory within a local computer associated respectively with each section. Each local computer is provided with at least two communication ports. A local terminal may be selectively connected to any local computer via one of the communication ports to enter and display timing setting data. A machine terminal or machine supervisory computer may be selectively connected to any local computer through the other one of the ports. A bidirectional communications interface enables data transfer between the selected local computers and selected data input/output devices.
