ABSTRACT:
A glass production system includes a glass forming machine having a multiplicity of operating mechanisms for converting gobs of molten glass into hollow glass containers, a plurality of solenoid valves responsive to valve drive signals for operating the multiplicity of operating mechanisms, and a plurality of valve driver circuits individually coupled to the solenoid valves and responsive to control signals to operate the valves and operating mechanisms in synchronism and in sequence for manufacture of the glass containers. An electronic controller has prestored control programming for generating valve control signals in synchronism and sequence, and a configurable or programmable logic array connected between the controller and the valve driver circuits for providing the controller-generated control signals to the valve driver circuits during normal operation. The configurable logic array is responsive to stop signals to provide second control signals to the valve drivers for controlled termination of operation at the glass forming mechanisms. The configurable logic array is responsive to the controller during a programming mode of operation for selectively configuring or reconfiguring the logic array to provide such second control signals in order to terminate operation at the operating mechanisms in the desired manner.
