A timing and control system for a glassware forming machine includes a ship computer system resident within a control room and a hot end console on the shop floor adjacent a multi-section glassware forming machine. The shop computer system executes a number of subroutines which permit configuration of the shop and of each IS machine section, such as routines for identifying on and off angles for the several mechanical devices associated with the sections. The hot end display includes a touch screen which permits the floor operator to implement certain changes in the timing and sequence of operation of the machine mechanical devices. The shop computer system implements subroutines which test for and detect potential conflicts or collisions between machine devices due to changes in the event times for the devices. The conflict testing occurs when the operator inputs the timing change information, issuing warning messages and disallowing the configuration change in the event of a conflict. Timing and sequence functions of the system are implemented using a link table associated with the on and off angles of two sub-events for each mechanical device. Linkable records are linked to storage locations in the link tables corresponding to 0.1 degree increments in the shop or machine cycle. Menu driven software facilitates user interface with the timing and control functions of the system, as well as system status reporting functions.
