Problems solved by technology

In the case of any changes, the machine operator is also exposed to the risk that the productivity of the machine is reduced by the additional load associated with the monitoring of the process data, since less computing power is now available for the actual control tasks

Embodiment Construction

[0026] figure 1A real controller 1 for controlling a real machine tool 2 is shown in an extremely simplified and schematic illustration. Advantageously, the real controller 1 is configured as a computer numerical controller (CNC). A CNC 1 controls a machine tool 2 for manufacturing a real workpiece 3 . Often, the machine tools do not operate autonomously, but instead the machine tools work in conjunction with other machine tools used to manufacture a particular item in a larger manufacturing complex. In this case, it is necessary to coordinate the production by means of the individual machine tools with one another. For this purpose, each individual machine tool, in particular its controller, transmits corresponding data on the type, quantity, quality, etc. of the workpieces produced to the superordinate processor unit 5 . The superordinate processor unit 5 can be a process control system, in particular a SCADA system, an MES system or an ERP system.

Abstract

When carrying out an industrial process or during the operation of an industrial system or machine, relevant data is to be detected without additionally loading the control of the industrial process or the system or machine in question. For this purpose, the invention provides a control system (1, 4, 5; 1', 4', 5'; 1'', 4'', 5'') with a real control (1; 1'; 1'') for controlling an industrial process, a system or a machine; a virtual control (4; 4'; 4'') for simulating the control of the industrial process, the system, or the machine; synchronization means for synchronizing the real control (1;1'; 1'') and the virtual control (4; 4'; 4''); and a higher-level processor unit (5; 5'; 5'') for detecting and / or generating operating data and / or state data with respect to the process, the system,or the machine, wherein the operating data and / or state data is based on data originating from the virtual control (4; 4'; 4''). By requesting the data from the virtual control (4; 4'; 4''), the realcontrol (1; 1'; 1'') is not additionally loaded.

Description

technical field [0001] The present invention relates to a control system comprising a real controller for controlling an industrial process, facility or machine and a virtual controller for simulating the control of the industrial process, facility or machine. Background technique [0002] Different requirements must be met when manufacturing workpieces with the aid of CNC machine tools and other production machines. Above all, workpieces of defined quality must be produced in the shortest possible time. Downtimes caused, for example, by wear, failure or damage of tools or machine components must be avoided. Workpieces that lie outside permissible manufacturing tolerances must be avoided or at least detected and, if necessary, sorted out. [0003] A similar situation manifests itself when controlling industrial facilities or industrial processes. Here, downtimes lead to high costs and must therefore be avoided. [0004] In order to continuously measure "process quality" ...
