METHOD FOR OPERATING AN END-USER OF AN ISOCHRONOUS CYCLICAL COMMUNICATION SYSTEM

摘要

The invention relates to a method for operating an end-user (306) of an isochronous cyclical communication system (300), comprising the following steps: receipt of a synchronisation data telegramme (510) from a connecting user (303) in the communication system (300) by the end-user (306), whereby the synchronisation data telegramme is affected by the run time (T, T1, T2) of a transmission run between the connecting user and the end-user, synchronisation of a time base of the end-user (306) by means of the synchronisation data telegramme, resulting in a synchronisation of the time base with a tolerance corresponding to the run time, cyclical processing of a transmission list by the end user (306) within a communication cycle (500, 502) corresponding to the time base of the end user, whereby the transmission of a data telegramme (700) occurs according to the transmission list from the end user to the connecting user at the earliest at the beginning of the communication cycle (500, 502) and at the latest at a point equivalent to the tolerance (T) before the projected transfer time point of the relevant data telegramme by the communication user (303).
