Patent number: 11809796Abstract: A design support device includes an operation reception unit that receives an operation from a user, a program creation unit that creates a ladder program in accordance with the operation received by the operation reception unit, and a circuit block extraction unit that extracts a circuit block from the ladder program when the circuit block is formed and a predetermined condition is satisfied. The circuit block is formed by detecting that one end of a circuit including a plurality of program elements is connected to one of two power rails included in the ladder program and that another end of the circuit is connected to another one of the two power rails. Further, there is a circuit block memory that stores configuration information of the circuit block extracted by the circuit block extraction unit. There is also a notification unit.Type: GrantFiled: January 9, 2020Date of Patent: November 7, 2023Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Kenta Tomonaga, Tomo Horikawa

Patent number: 9678160Abstract: An industrial automatic-diagnostic device connected to an FA system in which a plurality of FA devices are connected to each other, the industrial automatic-diagnostic device includes: an engineering tool; and a display unit. Based on interface connection information and device configuration information of a corresponding FA device held by each of the FA devices, the engineering tool creates overall configuration information of the FA system and displays an overall configuration of the FA system on the display unit based on the overall configuration information. When an abnormality occurs in the FA device, diagnosis information about an abnormal part self-diagnosed by the FA device and abnormality contents with respect to the abnormality occurred in a corresponding abnormal part is obtained. Based on the obtained diagnosis information, occurrence of an abnormality is displayed in an abnormal part in an overall configuration of the FA system displayed on the display unit.Type: GrantFiled: December 9, 2010Date of Patent: June 13, 2017Assignee: Mitsubishi Electric CorporationInventors: Tomo Horikawa, Kunio Ooba, Taku Watanabe

Publication number: 20110295388Abstract: When constituting a ladder program edition device that edits a ladder diagram, there is provided an edit control unit that generates data of a logical expression corresponding to a logical structure of an input condition and an output condition in a ladder diagram based on an arrangement of circuit elements in a ladder diagram, sets circuit elements that specify the input condition as one circuit unit of one input and one output for each input condition based on the data of the above logical expression, and connects output ends of circuit units to be connected in parallel with each other in the ladder diagram. With this configuration, generation of a syntactically erroneous ladder diagram is prevented.Type: ApplicationFiled: February 4, 2009Publication date: December 1, 2011Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Hideaki Iwata, Terumasa Yasui, Hirofumi Kai, Hiroshi Hamazaki, Tomo Horikawa, Takayuki Yamaoka
