    摘要: Not any special display is required to provide a monitor displaying of I/O data and timer/counter data during operation of programmable controller. Instead, the display of program console will be utilized to display instruction codes and addresses or error messages in characters. Multiple number of sets, in which the numbers of either I/O data or timer/counter data which optionally specified with numbers, are displayed simultaneously on the character display of the program console.

    摘要: 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.
