Patent number: 12147374Abstract: A distributed control system includes a tree topology network or a daisy-chain network including a communication parent station, communication child stations, and a plurality of communication paths among the communication parent station and the communication child stations, in which the communication parent station and the communication child stations include a scheduling unit that controls a transfer cycle that is temporal intervals of data transfer. The scheduling unit sets the transfer cycle that is the fastest out of a plurality of the data as a reference cycle, counts the number of times each time the reference cycle elapses, and imparts a value of the number of times to the reference cycle as a cycle number. When the cycle number reaches an optional number, the number of times is returned to an initial value, which makes one cycle of transfer control, and the transfer control is repeatedly executed.Type: GrantFiled: June 11, 2020Date of Patent: November 19, 2024Assignee: Hitachi High-Tech CorporationInventors: Kazushi Yamashina, Takashi Saegusa, Yoshiro Gunji, Tetsuji Ohsawa, Yutaka Kasai, Junichi Kitamura, Naoya Ishigaki, Shusaku Maeda, Yoshikuni Yokose

Patent number: 6883053Abstract: A data transfer control circuit includes several data receiver-transmitters, each having an interrupt identification register. Interrupt signals from the data receiver-transmitters are combined into a single interrupt signal by an interrupt controller. One of the data receiver-transmitters has an interrupt status register with bits indicating the logic levels of the interrupt signals from each of the data receiver-transmitters. A host device that receives the interrupt signal from the interrupt controller can read the interrupt status register to determine which data receiver-transmitter caused the interrupt, then read the interrupt identification register of that data receiver-transmitter to identify the interrupt source, without having to search through the interrupt identification registers of other data receiver-transmitters.Type: GrantFiled: October 12, 2001Date of Patent: April 19, 2005Assignee: Oki Electric Industry Co., Ltd.Inventors: Noriaki Shinagawa, Shusaku Maeda
