    摘要: The present invention relates to the provision of a modular control system for a glass forming machine. The glass forming machine control system comprises one central control unit (20) and one machine control unit (22), which are connected via a high-speed data bus (32). The machine control unit (22) is spread out to a plurality of peripheral control units (24, . . . , 30) via a plurality of high-speed data buses (34, . . . , 40). The machine control unit (22) is adapted to distribute control signals received from the central control unit (20) to the peripheral control units (24, . . . , 30) in real time.

    摘要: The present invention constitutes a data crossloading system for use with a programmable controller system having primary and secondary (or "back-up") systems each of which have redundant hardware components and have data structures associated with these components. The present invention further relates to the interconnection of the hardware components and to the processes for providing redundant data structures which enable a secondary or back-up system to rapidly and effectively assume control when a malfunction occurs in a primary control system. Both systems are connected via the same remote data links to common I/O racks which interface to sensing and output devices on the equipment being controlled. Data structure information in the primary system is specially crossloaded to the secondary system so that when a malfunction occurs that shuts down the primary system, the secondary system can begin execution of the same control programs and input and output the same data to the same I/O racks based on up to date data from the primary system. The crossloading of the data is accomplished through the use of special backup modules in both the primary and secondary (backup) control systems connected by a high speed communications link. Communications take place through the use of program utilities which establish a tightly coupled communications network between the primary and secondary systems. Additionally, on-line editing is enabled in stages so that when either control system can not properly execute the edit it is rejected. This system insures that edits can not take place in the primary system without being concurrently implemented in the secondary system.

    摘要: A communication network for programmable logic controllers (PLC) wherein selected memory means of each PLC has at least two ports directly accessible by other PLC and certain registers of the PLC are identical. Each PLC further has an interblock gap timer to signal the PLC when its transmit time slice is to occur. The time slice consists of a block transmit time and an interblock gap time. The total update time has been optimized to engable efficient, high-speed transfer of blocks of data between the PLCs.
