Graphical input method for control system implementation

摘要

The method for system control and parameter set up by means of a computer uses a graphics display system. The user inputs a network description by means of graphical symbols with connections and links to the computer. The connections implement an exchange of system events, and the symbols for sensors, actuators or internal functions of the internal control programme generate and process events. The network description is converted by an input programme to a programme store, which is then executed by the computer system to perform the control function.
