<p>PURPOSE: To facilitate the understanding and verification of the system operation in order to simplify the debugging operations and to improve the debugging efficiency by displaying in real time the behavior of a complicated system and at the same time by performing the graphical debugging operations. CONSTITUTION: A sequence control monitor 7 consists of a storage 1 which stores an information file 2, an input device 3 which inputs the user input events through a pointing device 4 and a character input device 5, and a memory 6 which stores the monitor 7. Then a state storage part 9 stores the step and shift condition states. In such a constitution, the route that is carried out by a sequence control model is displayed in real time and with emphasis. Then a break point is set at every step, and the internal variables of the step and shift conditions are displayed. Furthermore, the graphical substitution (value change) processing can be applied to the internal variables of the step and shift conditions.</p> |
