Operating method for a coating system, and coating system for carrying out the operating method

A method to operate a coating system that coats components with a coating agent with an applicator, comprising:

• a) coating the components with the coating agent, wherein component-related process values are obtained which represent operating variables of devices of the coating system during the coating of the individual components, and wherein a specific component-related coating quality results during the coating of the individual components,
• b) determining the component-related process values of the coating equipment,
• c) determining the component-related quality values, the quality values reflecting the coating quality of the individual components, and
• d) determining quality-relevant anomalies of the process values for detecting coating defects during the coating of the individual components in the context of a prediction operation during the coating of the components, and
• e) determining the position of the coating defects corresponding to the anomalies on the component surface of the coated components by evaluating the process values.
