A cyclical time-based communication system, for the transmission of data (DATA) between users, comprising a databus and users connected thereto. The data transmission occurs within cyclical repeating timeframes, each with at least two timeslots. Each timeslot is provided for the transmission of a message (Ni). A message (Ni) comprises at least part of the data (DATA) and each message (Ni) is provided with a code (ID). The bandwidth available for data transmission may be better utilized, if the code (ID) is placed within the message (Ni), each message (Ni) is additionally provided with time information concerning the timeslot which may be extracted from the code, and at least one of the timeslots may be used for transmission of various messages in various cycles. In a preferred embodiment the information relating to the current cycle comprises an ordinal number. In the simplest case the number has two values 0 and 1.
