Abstract
Abstract Trouble of a plurality of controlled devices operating in asynchronism with each other can be diagnosed by only connecting a trouble diagnosis apparatus to the conventional programmable controller, without preparing a special trouble diagnosing program on the user program. In another trouble diagnosis apparatus, the reference diagnosis input/output pattern series can be formed by first storing all the input/output pattern series and then deleting unchanged input/output from those to be diagnosed. Further, another trouble diagnosis apparatus includes an input/output designation mode, an instruction mode and a diagnosis mode. In the input/output designation mode, operator can designate important input/output to be registered and deletes unimportant input/output from all the input/output to be diagnosed to find fault locations.
