Patent number: 11402815Abstract: A control apparatus where control programs and information programs coexist is allowed to change programs flexibly. The control programs and information programs are installed in the control apparatus, which is provided with a shared area. The shared area is an area that at least one control program and at least one information program can access. Shared information is stored in the shared area. The shared information includes at least one of information related to an I/O port accessed by the control programs, and information related to the control program. Each control program is a program that performs scan operation of outputting control information on the relevant control object apparatus coupled to the I/O port accessed for controlling a control object apparatus with respect to the control program, to this I/O port. Each information program is a program that performs information processing that does not include the scan operation.Type: GrantFiled: February 28, 2019Date of Patent: August 2, 2022Assignee: HITACHI INDUSTRIAL EQUIPMENT SYSTEMS CO., LTD.Inventors: Mitsuhiro Imai, Yoshinori Mochizuki, Fumiyuki Tamura

Patent number: 11194739Abstract: A control apparatus that accesses at least one I/O port of one or more I/O ports coupled to one or more control object apparatuses to control operation of a control object apparatus coupled to the I/O port includes a processor unit that executes a plurality of programs, and a storage unit that stores information on the one or more I/O ports and serves as a base of one or more shared areas each of the plurality of programs can access. The plurality of programs include one or more information programs in addition to one or more control programs. Each of the one or more control programs is a program that performs a scan process to output control information on the control object apparatus coupled to the I/O port. Each of the one or more information programs is a program that performs information processing different from scan operation.Type: GrantFiled: August 23, 2018Date of Patent: December 7, 2021Assignee: Hitachi Industrial Equipment Systems Co., Ltd.Inventors: Mitsuhiro Imai, Fumiyuki Tamura, Yoshinori Mochizuki

Publication number: 20210373538Abstract: In a control apparatus allowing control programs and information programs to coexist, execution management data that indicates the upper limit of resources that are resources usable by the programs is enabled to be appropriately changed. The control apparatus downloads at least one of one or more object programs (one or more programs among one or more control programs and one or more information programs) from a program distribution apparatus via a network and one or more network ports. At timing different from the timing of the download, the control apparatus changes the execution management data that indicates the upper limit of resources that are resources usable by the object program in relation to a plurality of computing resources of the control apparatus. Each control program is a program that performs a scan operation of outputting control information on the control object apparatuses coupled to I/O ports.Type: ApplicationFiled: June 27, 2019Publication date: December 2, 2021Inventors: Mitsuhiro IMAI, Fumiyuki TAMURA

Patent number: 7716405Abstract: A computer system, being a stack bus system in which a plurality of computer modules are stacked and connected to one another and being capable of automatically matching and allocating bus resources such as clocks and interrupts, is provided. In the computer system including one system module and n peripheral modules, each peripheral module includes an interrupt selector, a clock selector, an arbitration signal selector, a resource decision unit, and a position identification unit. The position identification unit cooperates with a position configuration unit present in the system module to identify a position of the module, which includes the position identification unit, in the computer system, and autonomously decides bus resources used by the module. By allowing the interrupt selector, the clock selector, and the arbitration signal selector to select and use the decided bus resources, each peripheral module can match and configure the bus resources in the computer system.Type: GrantFiled: November 15, 2006Date of Patent: May 11, 2010Assignee: Hitachi Industrial Equipment Systems Co., Ltd.Inventors: Tsutomu Yamada, Hiromichi Endoh, Noritaka Matsumoto, Satoru Funaki, Tatsuya Maruyama, Atsushi Ito, Fumiyuki Tamura, Norihisa Yanagihara, Makiko Naemura
