A communication method and a master-slave system, for a field bus configures according to the AS-interface standard, are disclosed. Such a master-slave system for a field bus configured according to the AS-interface standard connects a master to a number of slaves. This field bus forms a first communication channel for the master and the slaves. In at least one embodiment, the master communicates with the slaves in sequence via telegrams, which are each uniquely associated with one of the slaves. Between the master and slaves a second communication channel is provided in at least one embodiment, via which one of the telegrams may be repeated, in addition to the first communication channel, if the communication of said telegram via the first communication channel has failed.
A communication method for a field bus configured according to an AS-interface standard as a first communication channel via which a master connected to the field bus is able to serially communicates with a number of slaves connected to the field bus in a cycle, the method comprising:
A master-slave system for a field bus which is configured according to the AS-interface standard, connects a master to a number of slaves and forms, for the master and the slaves, a first communication channel via which the master is able to serially communicates with the slaves in a cycle, the master being able to communicate with the slaves in succession in a cycle using messages which are each uniquely assigned to one of the slaves, the system comprising:
The master-slave system as claimed in claim, wherein the second communication channel has a relatively lower transmission quality than the first communication channel.
A communication method for a field bus, configured according to an AS-interface standard as a first communication channel for a master, connected to the field bus, to serially communicate with a number of slaves connected to the field bus in a cycle, the master being able to use messages, when communicating with the slaves in succession in a cycle, which are each uniquely assigned to one of the slaves, the method comprising:
