Abstract

The invention relates to a system and a method for transmitting telegrams. The system has at least one first communication means provided for sending telegrams and at least one second communication means provided for receiving telegrams, with a telegram having a check value that can be determined from a useful data component of the telegram, with the first communication means having a first telegram counter provided for assigning a count value to a telegram in accordance with a send sequence. To improve error detection during the transmission of telegrams it is proposed that the count value for determining the check value be a constituent of the useful data component is, that information signaling a change in the count value be a constituent of the useful data component when the telegram is transmitted, that the second communication means have a second telegram counter, and that means be provided for synchronizing the first and second telegram counter.
