摘要：The invention relates to a communication method and to a master-slave systemfor a field bus configured according to the AS-interface standard. Such a master-slavesystem for a field bus (F) configured according to the AS-interface standard connects amaster (M) to a number of slaves (S1, S2,..., Sn). This field bus forms a first communicationchannel (K1) for the master (M) and the slaves (S1, S2,..., Sn). The master communicateswith the slaves (S1, S2,..., Sn) in sequence via telegrams, which are each uniquely associatedwith one of the slaves (S1, S2,..., Sn). Between the master (M) and slaves (S) a secondcommunication channel (K2) is provided, via which one of the telegrams may be repeated,in addition to the first communication channel (K1), if the communication of said telegramvia the first communication channel (K1) has failed.
