Abstract
In a method for initializing a bus system, and a bus system having a master module and serially disposed bus subscribers, the master module asks the bus subscribers to log into the master module. After logging into the master module, each bus subscriber waits a predefined period of time to see whether a further bus subscriber logs into the master module, and closes the bus system if no further bus subscriber logs into the master module within the predefined period of time.
Claims21
A method for initializing a bus system that includes a master module and bus subscribers arranged in series, comprising:
- asking the bus subscribers, by the master module, to log in to the master module;
- after the asking, logging in to the master module by a first bus subscriber downstream from the master module;
- after the logging in, waiting, by the first bus subscriber, for a predefined period of time to ascertain whether a second bus subscriber downstream from the first bus subscriber logs in to the master module;
- after the waiting, (a) closing the bus system, by the first bus subscriber, if no second bus subscriber logs in to the master module within the predefined period of time, and/or (b) logging in to the master module by a second bus subscriber within the predefined period of time and waiting for a further predefined period of time to ascertain whether a third bus subscriber downstream from the second bus subscriber logs in to the master module, the second bus subscriber closing the bus system if no third bus subscriber logs in to the master module within the further predefined period of time.
