    摘要: A destination node in a data network for transmission of real-time data by a data telegram, the data telegram including an identification, data and a transfer status, is provided. The destination node includes a device for receiving a first data telegram, a device for storing the data of the first data telegram and an assigned timer value, a device for receiving a second data telegram and a device for replacing the stored data of the first data telegram, wherein the stored data of the first data telegram is replaced with data of the second data telegram. Further, a method and a non-transitory storage medium are provided.

    摘要: The invention relates to a method for transmitting real time-critical data using data messages in a data network. The data messages have an identification, useful data and a transfer status. According to the inventive method, data messages comprising errors are replaced by replacement messages that have the same structure as the data messages. The replacement message has the same identification as the data message to be replaced and is thus forwarded via the switching node, which would have been used to route the error-free data message. The replacement message can contain details of the type of transmission error.

    摘要: The invention relates to a method for operating an isochronous, cyclic communication system, wherein one communication cycle can be subdivided into a first part for real-time communication and a second part for non-real-time communication. The communication system comprises subscribers and a memory is provided to store configuration data in each subscriber. The inventive method comprises the following steps: the communication system is operated with first configuration data for real-time communication; second configuration data is transmitted for real-time communication in a second part of one or several communication cycles; the second configuration data is stored in the memories of the subscribers; a transfer time indicating the moment in time when transfer occurs from the first configuration data to the second configuration data.
