Abstract of the Disclosure A programmable automatic controller for operating a section of a glassware forming machine having a plurality of components which operate in a timed or sequential relationship with one another. The controller includes a timing means for generating cycle clock pulses in synchronism with the operation of the machine, wherein the cycle clock pulses provide an instantaneous indication of the time elapsed in each cycle of operation of the machine. A random-access memory (RAM) stores the relative times during each cycle of machine operation when each of the plu- rality of machine components are to be enabled and/or inhibited. When the time elapsed in a cycle corresponds to a component actuating time stored in the running storage, an actuating sig- nal is generated by a comparator. This signal is coupled to a machine component addressing arrangement which provides a compo- nent enable or inhibit command signal to the addressed component whose actuating time compared to the cycle time elapsed. Accordingly, in a cycle of operation a plurality of component operating command signals are generated which command the respective machine components to initiate and terminate opera- tion at preselected time intervals. Means are provided for selectively varying the component actuating times stored in the RAM while the machine is stopped or in operation. The controller is designed to operate directly next to the section it controls since its design employs a minimal number of components all able to function with a minimal amount of cooling.
