Abstract
There is described a method, a bus protocol, a peripheral module, a processing unit, a hub and also to a system consisting of said components, for event signaling between at least one peripheral module and a processing unit by means of a system bus. In this case the data to be transmitted data is encoded into a larger symbol space, from which a standard idle symbol is used in telegram pauses for synchronizing a connection between transmitter and receiver. A message present at the peripheral modules is enabled to be signaled to the processing unit independently of the telegram traffic initiated by the processing unit. This is achieved by a peripheral module wishing to signal an event to the processing unit sending to the processing unit in a telegram pause, instead of the standard idle character, a signaling sequence consisting of an alarm idle symbol and an alarm identifier which contain information about the relevant event as well as the module address of the peripheral module at which the event is present, with the information about the event also being transcoded into the larger symbol space.
