Publication number: 20220163939Abstract: A master device manages a plurality of slave devices constituting a network including a ring topology. The plurality of slave devices includes: a first slave device serving as a starting point and a terminal point of the ring topology; and a plurality of second slave devices connected between a first output port of the first slave device and a second output port thereof and constituting the ring topology. On the basis of a network configuration detected when the second output port and the output port of a second slave device paired with the second output port are available and of a network configuration detected when the second output port and the output port paired therewith have been made unavailable, the master device determines an incorrect wiring path between the first output port and the second output port and outputs information indicating the incorrect wiring path to an information processing device.Type: ApplicationFiled: February 10, 2020Publication date: May 26, 2022Applicant: OMRON CorporationInventors: Shigenori SAWADA, Norihiro MAEKAWA

Publication number: 20220147006Abstract: A control system includes a control apparatus functioning as a master, and plural slaves which are network-connected to the control apparatus. The slaves each have identification information. The control apparatus includes executes a first instruction to set specified identification information to each of one or more specified slaves. The control apparatus outputs first error information indicating which slave that the setting of the identification information to which is failed, among the one or more specified slaves.Type: ApplicationFiled: February 14, 2020Publication date: May 12, 2022Applicant: OMRON CORPORATIONInventors: Akihiro ISHIMURA, Kojiro BABA, Taishi KAWAGUCHI, Norihiro MAEKAWA

Publication number: 20190197016Abstract: A control system and control device are provided capable of flexibly realizing communication processing without requiring an additional unit even when a plurality of units having a communication function are present is provided. The control system includes a first unit having a first communication port for transmitting and receiving data, and one or more second units electrically connected to the first unit. Each of the second units includes a logical communication unit for transmitting/receiving data to/from the device electrically connected to the first communication port of the first unit. The first unit includes a forwarding processing unit which forwards transmission data transmitted from the second unit to the device which is a transmission destination.Type: ApplicationFiled: October 15, 2018Publication date: June 27, 2019Applicant: OMRON CorporationInventors: Norihiro MAEKAWA, Yutaka TAHARA, Kazunari MIYAKE, Koji KARASUYAMA, Yuji IKEO, Ryosuke FUJIMURA

Patent number: 10274936Abstract: Provided is a control apparatus that can, by causing multiple control programs that include motion computation programs to be executed in parallel, shorten the execution cycle of control programs that are executed cyclically. A microprocessor is configured to execute multiple control programs in parallel. When executing communication commands included in control programs that are to be executed in parallel, a scheduling program causes the microprocessor to execute the communication commands such that there is no competition between communication processes in a communication controller.Type: GrantFiled: November 24, 2015Date of Patent: April 30, 2019Assignee: OMRON CorporationInventors: Shigeyuki Eguchi, Norihiro Maekawa, Yoshihide Tamura, Yoshihide Nishiyama
