Method of Providing Data Access in an Industrial Automation System, Computer Program Product and Industrial Automation System |
摘要 |
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.
