PURPOSE:To eliminate a data input error and rule out a data reinput process by automatically updating necessary data only with change of display position of symbols on a skeleton display screen. CONSTITUTION:A facility symbol which is moved through a man-machine interface is selected on a skeleton display screen to designate a new display position (S1). A pixel display position slot data of instance data of the moved symbol is changed (S2). A data element including instance of the moved symbol is searched from connecting lines to obtain a connecting line information of the moved symbol (S3). With this information, a connecting line is redrawn depending on a program and a connecting line data is updated automatically (S4) and a symbol of grounding, etc., is automatically moved the desired position on the updated connecting line (S5). A connecting line coordinate slot data of a connector instance is automatically updated by a program on the basis of the searched ground line information (S6). |
