Abstract
An electronic timing control system for a glassware-forming machine includes a mini-computer master controller which controls the timing and sequence of operation of each of the individual section glassware-forming machine components. The master controller includes a plurality of control modules for section timing, conveyor motion, etc., each module of which outputs information to a corresponding serial multiplex I/O module. Each of the I/O modules connected to the master controller feeds data to a common data cable, according to a multiplexing scheme administered by the master controller. Data from the data cable is fed to each of the sections of the I.S. glassware forming machine, and particularly to a plurality of serially connected serial multiplexer modules. Each of the serial multiplexer modules corresponds to a section functional component operable to receive and form molten glass gobs into glassware articles. Each serial multiplexer module has a unique address. Information conveyed by the data cable includes a specific address for the module to which the data being transmitted is to be provided. Thus, although control data from the master controller is provided serially to …
