Increasingly, innovative functionality in embedded systems is realized by connecting previously autonomous embedded systems.This requires real-time communication and coordination between these connected systems.Modelica and the StateGraph2 library provide a good environment for modeling embedded systems including controllers and physics.However, it lacks appropriate support for modeling the communication and coordination part.In this paper, we present an extension to the State-Graph2 library that enables modeling asynchronous and synchronous communication and rich real-time constraints.We illustrate our extension of the State-Graph2 library by modeling and simulating two miniature robots driving in a platoon.
