ABSTRACT:
A device for a modularized system with decentralized and function-executing modules comprising a module with associated clock that is arranged to effect time-stamping of events associated with the system and of reference events selected from among these. The module comprises a memory device for storing the module's time stamps relating to the events noted by the module and to the reference events selected from among these. The module also comprises a microprocessor that generates messages related to the module's stored time stamps. In addition, the module is arranged to transmit the respective generated messages to a time conversion unit via one or more communications links, and the time conversion unit is arranged, after any intermediate storage, to relate the module's respective noted reference event and effected time-stamping to additional reference events and time-stamping introduced into the unit or already in the unit.
