 For example, it is used to simulate the transmission time or the failure of bus messages.
 A Bus Simulation FMU must provide enough bus terminals for all FMUs that are interconnected via a bus.
 The implementation of a Bus Simulation FMU can be dynamic or static, potentially generated by a tool.
-<<network-abstraction>> explains the topic of binary protocol data within the bus terminal variables in more detail.
 Because the Bus Simulation FMU can provide the described functionality, all FMUs that want to transmit bus messages send their messages to the Bus Simulation FMU.
 The Bus Simulation FMU can then acknowledge, delay or even reject messages and forwards messages to recipients accordingly.
+Some features may depend on the abstraction layer that is used.
 Also in this case, the FMU importer does not require any special features for bus simulation, apart from supporting FMI variables, clocks and terminals.
 The figure below shows two FMUs which are connected to a specific Bus Simulation FMU.
 The total of three FMUs are executed on a common FMI 3.0 importer.

+The usage of this architecture type allows the integration of this layered standard into an already existing simulator, which implements network communication with proprietary interfaces.
+In this case, it may also be possible to integrate other, for example manufacturer-specific, formats into a bus simulation.
