Method for providing functions within an industrial automation system and industrial automation system

摘要

To provide functions within an industrial automation system, functions of the automation system are made available by web applications. The web applications are interconnected on the client side during the process of control program execution. The web applications are delivered via a unified application programming interface that includes a cross-component application programming interface for initiating and unloading of application components and a component-specific application programming interface for event handling and deployment of component functions. Component instances are linked by means of an application programming interface for defining interactions between application components.
