METHOD FOR DATA TRANSMISSION WITHIN AN INDUSTRIAL COMMUNICATION NETWORK, AND COMMUNICATION DEVICE

摘要

For data transmission within an industrial communication network, selected datagrams (500, 500'^x) are transmitted within predetermined time intervals (10, 20), which are synchronized at all network nodes. In each case, a number of network nodes from the respective source network node to the respective target network node is determined for forwarding the selected datagrams (500, 500'). In the event of a determined number of network nodes corresponding to at least one predefined threshold value, the selected datagrams (500, 500') are transmitted during first periodic time intervals (10) having a first protection interval length (12). In contrast thereto, if a determined number lies below the threshold value, the selected datagrams (500, 500') are transmitted during second periodic time intervals (20) having a second protection interval length (22), which is shorter than the first protection interval length.
