1. A system for operator control of subunits of a technical installation by editing graphical objects, the system comprising: a graphics editor for monitoring and analyzing a user operator control command; a data editor, being started by said graphics editor, when a user selects a graphical object, said data editor producing and/or updating configuration data for a represented subunit and the configuration data being associated with the graphical object selected, then said graphics editor visually displaying the graphical object with an updated association between the updated configuration data and associated updated graphs, said data editor using the updated configuration data to control or reconfigure the technical installation or the subunits; a symbol database connected to and supplying graphical objects to said graphics editor, the graphical objects graphically representing the respective subunits in the technical installation; and a process data element updating and combining measured process data from the respective subunits for forming the updated graphs for the respective subunits.
