One main difference of controller-nets in comparison with other local area networks is, that they have to meet realtime requirements. Messages, crossing the communication lines, have to do that within a certain time to fulfill certain control functions. To support all phases of network development, beginning with planning and ending with test and maintenance, an according toolset family - comprising Simulator, Emulator and Analyzer - has been introduced by I+ME-Company. Planning structured realtime controller nets is the first and basic phase of a large project. Faults within this phase are very difficult to remove afterwards and may become very expensive. The presented simulator is a powerful tool to support this phase. Networks topology, its protocols, its transmission rates, its message load and its noise load are put together to define and to run a formal network model, resulting into a verified network specification, which will be a god basis to the phase of implementation.
