Abstract: A method for establishing a global time base in a time-controlled communications system comprising a network and multiple subscribers connected to it. At least one of the subscribers of the communications system is defined as a time master with which the remaining subscribers are synchronized. In order to allow for a synchronization of the communications system that is on the one hand as simple as possible and realizable at low cost and on the other hand is secure and reliable, the present invention provides for one subscriber to be defined as the main time master and at least one further subscriber to be defined as a reserve time master. The order of the reserve time masters is predefined in the event that more than one subscriber is defined as a reserve time master. First an attempt is made to synchronize all subscribers of the communications system with the main time master.

Abstract: A method for exchanging data in messages between at least two users connected by a bus system, where each of the at least two users includes a predefinable and/or ascertainable timing mark, includes causing the at least two users to transmit, via the bus system, messages including the data. The method also includes causing a first user, in a function as timer, to control the messages as a function of time in such a way that it repeatedly transmits a reference message, which contains time information of the first user, via the bus at a specifiable time interval. Further, if the timing mark of the second user is reached without a reference message of the first user reaching the second user, the second user is caused to take over the function of timer by transmitting its own reference message with its own time information via the bus system.

Abstract: The present invention relates to a local monitoring unit, which is locally assigned to a bus controller of a user of a communication system, a central monitoring unit of a communication system for monitoring and/or controlling the access of multiple users to a data bus. An important feature of the provided monitoring concept is that the monitoring unit has a time basis of its own that is independent of a local time basis of a communication controller of the users and that is synchronized with a global time basis of the communication system. This separate local time basis is utilized in the monitoring unit to monitor and/or control the access authorization of the communication controller or of a bus driver to the data bus. In this way, sending conflicts of the users, in particular due to permanent disturbances in one or more users, may be reliably detected and prevented.
