Embodiment Construction

[0072] figure 1 Commissioning situations, which are particularly important for machine engineers, are shown purely diagrammatically.

[0073] Here, a plurality of automation components 1 , 2 , 3 of the machine 4 are networked with one another via a network 5 . In the embodiment shown, the automation component is formed in particular by a programmable logic controller 1 (hereinafter abbreviated as SPS) and two IO devices 2 , 3 .

[0074] Furthermore, the engineering tool 6 is also connected to the machine network 5 .

[0075] There are no connections to other networks, and in particular no "infrastructure" such as routers or name servers. Thus, the network of machines 5 forms a network of islands.

[0076] The decentralized autoconfiguration mechanism of IPv6 SLAAC ("Stateless Address Autoconfiguration", see RFC 4862) allows: each participant of the network can autonomously provide its own single IPv6 address. This simplifies the network configuration of the machine, since ...

Abstract

A method for automatically configuring a router (10) that has at least one upstream interface (11), connected or connectable to a higher-level subnetwork and / or a higher-level router, and at least one downstream interface (12), connected or connectable to a lower-level subnetwork (5), wherein it is monitored whether the router (10) receives, on the at least one upstream interface (11), messages providing notification of at least one domain, in particular as part of a DNS search list option (21), and, if no such message has been received over a prescribed period, a DNS island mode is automatically activated in which the DNS zone (22) of a local DNS server (14) of the router (10) is configured using a predefined island domain, and a transmission module (13) of the router (10) is prompted to send at least one message via at least one downstream interface (12), which message comprises the preconfigured island domain, in particular as part of a DNS search list option (31), and preferably an address (23) of the downstream interface (12). The invention furthermore relates to a method for automatic address configuration, a router (10), a computer program and a computer-readable medium.

Description

technical field [0001] The present invention relates to a method for automatically configuring a router. The present invention also relates to a method, router, computer program and computer readable medium for automatically configuring addresses. Background technique [0002] Machine and plant engineers, especially from the field of automation technology, want to be able to operate their machines more easily and thus at lower cost in the future as well. Decentralized autoconfiguration mechanism for IPv6, SLAAC ("Stateless Address Autoconfiguration", see RFC 4862, where RFC stands for "Request for Comments" and RFC 4862 is available at https: / / tools.ietf.org / html / rfc4862) Allows each participant to autonomously assign itself its own unique IPv6 address. This simplifies the previous network configuration of the machine, since no correct address configuration is required for the machine engineer. [0003] A particularly important commissioning situation for machine engineer...
