<p>PURPOSE:To facilitate an operation by hierarchically constituting a process flowchart which is going to be displayed. CONSTITUTION:The process flowchart which is going to be displayed has a hierarchical constitution which sequentially leads from a plant whole chart in the highest rank level to the flowchart whose object range is reduced, such as the plant whole chart 21 as a first level, the high rank process flowchart 22 as a second level, the low rank process flowchart 23 as a third level and a loop chart 24 as a fourth level. As for the development to the low rank level, a first level dedicated access push-button PL11 is pushed so as to display the plant whole chart 21 on a screen, on which a desirable part is touched so as to display the high rank process flowchart 22 showing the constitution of the part on the screen. Next, on the screen of the high rank process flowchart 22 the desirable part is touched so as to display the low rank process flowchart 23 showing the constitution of the part on the screen, on which a desirable minimum unit is touched to display the loop chart 24 on the screen.</p> |
