    摘要: A system and method for providing time-critical services that are each assigned at least one server component formed by a software container which is loadable into a process control environment and which is executable at the process control environment, wherein a virtual IP stack is provided for each server component, which is connected to a virtual switch comprised by the process control environment, where each service additionally comprises a directory service component for determining services provided within the process control environment, where the directory service components are interconnected via a communication interface which is separated from the virtual switch and from the virtual IP stacks of the server components, and where an aggregator component formed via an additional software container is connected to the separated communication interface, where the aggregator component makes available, outside of the process control environment, reconciled information regarding the services provided via the server components.

    摘要: Coordinator and method for providing control applications via a communication network, wherein prior to migrating a flow control component of a control application to a server device, a coordinator checks whether a data stream for transmitting application data was set up for the control application, where the coordinator enables migration of the flow control component if a data stream has not been set up, in the event a data stream had been set up previously, a check is performed to determine whether sufficient resources for data transmission are available for paths to the server device, such that if sufficient resources are unavailable, migration of the respective flow control component is stopped, and if sufficient resources are available, the coordinator prompts set-up of the data stream to the server device and disconnection of the previously set-up data stream and enables migration of the flow control component to the server device.

    摘要: A computer network has ports connected to production machines (PM) and communicating with an assigned virtual user interface and a higher-ranking facility located outside the PM. Connection of an additional PM is monitored, in which case a commissioning service automatically assigns a virtual user interface to the additional PM, re-initializes an individual virtual computer network within the computer network and connects the additional PM to the virtual user interface via the re-initialized virtual computer network. Communication between the additional PM and the assigned virtual user interface is isolated from other communications until, a release command is specified. A then activated integration service automatically re-initializes a virtual router for connection to the additional PM via the virtual computer network and configures the re-initialized virtual router such that the additional PM communicates with the higher-ranking facility via the re-initialized virtual router.

    摘要: A method for providing an expanded name service for an industrial automation system, wherein name-address assignments between device names and communication network addresses are registered in a name service system to provide an expanded name service for an industrial automation system, where device names registered in the name service system have a hierarchical structure represented by a tree structure, where assignments between device names and plant identification codes are additionally registered in the name service system, where the plant identification codes are registered within the same tree structure as the device names, and where end nodes that are respectively assigned to the plant identification codes in the tree structure comprise either a reference to end nodes which are respectively assigned to the device names or intermediate nodes for plant identification codes comprise a reference to intermediate nodes that are respectively assigned to plant units.

    摘要: A method for automatic address configuration, router, computer program, computer-readable medium and method for automatically configuring a router that has an upstream interface, connected or connectable to a higher-level subnetwork and/or a higher-level router, and a downstream interface, connected or connectable to a lower-level subnetwork, wherein whether the router receives, on the upstream interface, messages providing notification of at least one domain as part of a DNS search list option, is monitored and, if the message is not received over a prescribed period, a DNS island mode is automatically activated in which the DNS zone of a local DNS server of the router is configured using a predefined island domain, and a transmission module of the router is prompted to send a message via the downstream interface, which message includes the preconfigured island domain as part of a DNS search list option, preferably an address of the downstream interface.

    摘要: A method is provided which enables industrial communication via the TSN protocol by means of sockets. Owing to the described method, the possibility of communicating with the socket programming known to the programmer via TSN streams is provided. As a result, simple use of the new TSN quality for simple Internet (IP) programming is possible. Existing applications can easily be expanded for TSN and can therefore benefit from the robustness of TSN in a simple manner. In addition, parallel operation is possible; the same mechanism is always used.
