In an industrial automation system comprising a plurality of industrial control devices connected to an industrial communication network, control and/or supervision functions of the industrial automation system are provided by services implemented by computer-based objects in industrial control devices. A computer-based object is assigned a first qualifier enabling the computer-based object to be accessed and/or modified during configuration of the respective service and/or a second qualifier enabling the computer-based object to be accessed and/or modified during runtime of the respective service. Upon a request for access to a computer-based object by a service consumer, the service consumer's operational state is determined. Depending on a set first and/or second qualifier of a computer-based object and depending on a determined operational state of a service consumer, access to the computer-based object is granted to the service consumer.

Method of providing data access in an industrial automation system, computer program product and industrial automation system

An automation system with a plurality of communicatively connected automation devices is disclosed. One of the connected automations devices serves as a domain controller and holds centrally in a memory data required for operation for the automation system and the automation devices. Hitherto frequently occurring multiple storage of such data is eliminated, the data is available at a central location for access by all the automation devices, and the domain controller, as a central data server, ensures consistency of the data administered and provided by it, which also permits access optimizations, such as e.g. device-, access- or structure-dependent temporary storage strategies.

Automation system and method for operating such an automation system

The embodiment of a respective application-specific call code, necessary in the existing art, as an external control element implemented in a separate component is described. The external control element is usable in any desired containers without thereby modifying the containers themselves or even knowing them at the time the external control element is designed. This may be used in data or information transmission systems, in particular process visualization systems. The components are implemented as software components, in particular as so-called ActiveX controls.
