Summary:PROBLEM TO BE SOLVED: To facilitate machine control using a programmable controller without adjusting the physical position of a sensor or the like, while allowing adjustment of the timing of sensor detection signals or the like. SOLUTION: A timing chart whose horizontal axis represents a lapse of time and whose vertical axis indicates on/off of an input contact or an output contact displayed by a ladder symbol on a ladder program, is displayed on the display screen of a programming tool 10. A signal waveform indicating the on/off of the input contact is adjusted over the timing chart to modify the ladder program related to the input contact. COPYRIGHT: (C)2010,JPO&INPIT
