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.
