<p>PURPOSE:To easily execute debugging for a sequence program and wiring, etc., by a user, by providing a label on each instruction word of a flow chart type program, and attaching a passing flag on the label. CONSTITUTION:The instruction word outputted according to a flow chart which displays a sequence is arranged at every group, and the label is provided for each instruction word, and a flag which is displays the passage of the label is provided on the label. And which label is passed while the sequence is executed, is displayed with the flag of the label, and the passing state of a sequence flow chart being displayed on a CRT display is hot-line displayed. Since it is possible to easily realize the trace and display of the sequence program of flow chart type PC, it is possible to reduce a debugging time at the time of developing a program and performing the test run of the system, or to reduce a down time when a fault is generated in the system.</p> |
