1. Method for transmitting user data (D) between subscribers in a network (N) by means of data messages (4) comprising:
- allocating in each case one message counter (TC) to the data messages (4), the message counter (TC) being specified individually for each data message (4), andignoring the contents of user data CD) of a subscriber who receives a data message (4) containing the user data CD) if the message counter (TC) of the data message (4) is not plausible on the basis of previously received data messages (4),characterized bycalculating the next transmitting time of the transmitting subscriber for a subsequent data message (4) as a function of the message counter (TC) of the preceding data message (4) and of a subscriber address assigned to the transmitting subscriber.

Abstract
A method for transmitting user data (D) between subscribers in a network (N) by means of data messages (4) has the following steps:
- allocating in each case one message counter (TC) to the data messages (4), the message counter (TC) being specified individually for each data message (4), and
- ignoring the contents of user data (D) of a subscriber who receives a data message (4) containing the user data (D) if the message counter (TC) is not plausible on the basis of previously received data messages (4).

- 10. Subscriber device for transmitting user data (ID) in data messages (4) in a network (N) of subscriber devices (2) by means of a data message generating unit which is set up for individually specifying a message counter (TC) for each data message (4) to be sent out, allocating the specified message counter (TC) to the data message (4) and sending out the data message (4) containing the user data (ID) to subscriber devices (2), and with a control device which is set up for checking the plausibility of the message counter (TC) of a received data message (4) and ignoring the user data (ID) of the data message (4) if the message counter (TC) is not plausible, characterized in that the subscriber device (2) is set up for calculating the next transmitting time of the transmitting subscriber device (2) for a subsequent data message (4) as a function of the message counter (TC) of the preceding data message (4) and a subscriber address assigned to the transmitting subscriber device (2)
