The controller simulator retains a control program for the controller and an analysis unit, and the analysis unit has a propagation flag tracking function wherein propagation flags are assigned to a variable within the control program, bits of the variable are set by inputting a prescribed value thereto as a malfunction input value, the bits are propagated each time the variable is involved in a calculation within the control program, the states of propagation of the bits are tracked, and the result thereof is output."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Malfunction influence evaluation system and evaluation method using a propagation flag","description":"Provided is a malfunction influence evaluation system comprising a controller simulator that simulates the operation of a controller, an input apparatus that provides input data to the controller simu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9606902","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
