METHOD FOR PROVIDING FUNCTIONS WITHIN AN INDUSTRIAL AUTOMATION SYSTEM, AND INDUSTRIAL AUTOMATION SYSTEM

摘要

In order to provide functions within an industrial automation system, functions of the automation system are made available by web applications that are combined by the client during control program execution to form interlinked web applications and are provided on a user interface on the client. The web applications are provided by means of a standard application programming interface that comprises a cross-component application programming interface for initializing and unloading application components and also a component-specific application programming interface for event handling and providing component functions. Component instances are linked by means of an application programming interface for stipulating interactions between application components.
