摘要:
An automation system with a data processing device and an automation device connected to a network, with the automation device including a network server, a current operating system and an application program running under the current operating system, can be updated by transmitting a new operating system to the automation device via the network. The network can be the Internet and/or an intranet.

Help system, automation device with a help system and method for providing help data The invention relates to a help system. The help system comprises a first help facility (2) which is preferably installed as part of an application on a data processing device (3), the first help facility (2) providing a user with help data on the basis of context data defined by the user, in particular on the basis of search terms, said help data being stored in the first help facility (2) and thus on the data processing device. A second help facility (5) is provided according to the invention, which is accessed by the data processing device preferably via the internet such that the context data defined by the user in relation to the first help facility (2) is automatically adopted in the second help facility as context data, the second help facility (5) providing the user with additional help data based on this context data, said help data being stored in the second help facility (5).
摘要:
A distributed operation is performed using at least one first and second computer-based object, wherein control information is used to influence or determine a property, a function of the first and/or second computer-based objects. The control information includes details of a parameter identifier, a value associated with the parameter identifier, a range of validity and a remote access attribute. The control information is provided in a retrievable manner, according to the included range of validity, in a memory organized according to ranges of validity and is associated with the first computer-based object. During a function or service call for performing the distributed operation, which is sent from the first computer-based object to the second, the control information is transmitted to the second computer-based object, provided in a retrievable manner in the memory organized according to the ranges of validity and associated with the second computer-based object.

摘要:
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.
摘要:
An access authorization for a computer-based object in an automation system comprising a plurality of network nodes is granted using a control file which is structured in line with a scheme for a markup language for granting access authorizations and which maps a hierarchic tree structure. In this case, access authorizations are mapped in an object model which has a hierarchic tree structure. A relevant subtree from the object model is ascertained for a selected network node, at which services are provided using computer-based objects, or when access to a computer-based object is requested, by an access guideline service. The control file is produced from the ascertained relevant subtree. The control file produced is made available for the selected network node or for access to the computer-based object.
摘要:
An automation system includes at least one automation object, with a directory for storing object names of the at least one automation object. An object name is assigned a directory entry which includes first information data as a reference to the automation object; second information data as a description of technological functionality; and third information data as a description of interfaces of the automation object. This results in immediate and permanent access to currently created (partial) solutions, so that parallel and/or distributed working on automation objects is possible.
摘要:
A method for identifying, authenticating and authorizing a user of protected data, in particular a use of protected in an automation system, whereby the user is identified by the user ID input by them in an input field in a login area, this input user ID is combined with a password input by the user and transferred with a one-way encryption function to a system ID which authenticates the user, at least this system ID is transferred in an access identifier from the login area to a protected area and the user is authorized by this transferred access identifier to obtain access to protected data in the protected area.
摘要:
A device and a method for distributing and forwarding requests to a plurality of web servers in an industrial automation arrangement. The device is configured to receive requests addressed to a well-known port, and the web servers are addressable by at least one local address and by means of one port number. The device is also configured to evaluate the destination URLs of the requests, where each of the requests have the same host header of the request and the server addressing components of the destination URLs are possibly identical, a path component of the URL in each case defines one of the web servers, and the device is configured to forward the request to one of the web servers defined by the path information.
