<p>PURPOSE:To shorten the initial display time by storing the graphic display data in the form of the internal evolution data of a CRT display device and adding the display updating data corresponding to the state change to the graphic display data by a host computer. CONSTITUTION:A host computer 41 detects the state change of each equipment and grasps these detected states. Thus the display data D stored in an auxiliary storage 42 are fetched into the computer 41 and then updated by a graphic display data updating part in accordance with the state change. That is, S2-S4 are changed to the OFF states from the ON states together with K2 and K3 changed to the power disconnected state from the charging states. The signal obtained by adding a state change signal to the graphic display data is sent to a graphic CRT display device 2 through a transmission line 3 and displayed on a CRT monitor. Thus the initial display time is extremely shortened.</p> |
