Abstract: The invention relates to a method for saving the same sequence of messages in several data sinks (DS), several data sources (DQ) independently sending data messages comprising identical message contents to said data sinks (DS) in a parallel manner. In order for the same sequence of messages to be saved, the data sinks (DS) predefine a time slot for the data sources (DQ) to collect the data messages, and the data messages are sent when said time slot is closed.

Abstract: The invention relates to a method for guaranteeing an identical message sequence in several data sinks, according to which several data sources transmit data messages in parallel and independently of one another to said data sinks. To guarantee an identical message sequence, according to the invention a clock-pulse generator delivers a predefined consecutive clock-pulse generator number to all data sources at constant cycle intervals, for example 50 ms, said number being transmitted together with a message counter number that is consecutive during the cycle interval and with the message content to all data sinks.
