Abstract

In a method of implementing a production process in an industrial production system having control equipment, a plant model of the industrial production system is created, and based on the plant model, at least one interface (SFC type) for external access to the control equipment is defined. A strategy is defined for the interface representing a single function of a functionality provided by the interface. A method call is defined for activating the functionality provided by the interface.

Claims

1. A method of implementing a production process in an industrial production system having control equipment, comprising:

creating a plant model of the industrial production system;

based on the plant model, defining at least one interface for external access to the control equipment;

defining for the interface a strategy representing a single function of a functionality provided by the interface; and

defining a method call for activating the functionality provided by the interface.

2. The method of claim 1, further comprising defining a setpoint for the strategy.

3. The method of claim 1, wherein actions are performed by the control equipment.

4. The method of claim 1, further comprising activating the control equipment via the method call.

5. The method of claim 1, wherein a functionality of the control equipment is activated via a synchronous method call.

6. The method of claim 1, wherein the interface is provided by a sequential function chart (SFC) type defined in a predetermined process control system.

7. The method of claim 6, wherein the predetermined process control system is a SIMATIC®

IT PCS 7 control system.

8. The method of claim 1, wherein the method is implemented in a manufacturing execution system (MES).
