This paper considers networked discrete-event systems as controlled subsystems, which are connected through digital communication depending on its environment. Most of the time the subsystems operate autonomously, however, they are able to react on external influences by coordinating their actions between each other. The behaviour of this system class is illustrated by means of a robot example. Each controlled subsystem is modelled by an Input/Output (I/O)-automaton in order to formalise its autonomous and cooperative behaviour. Moreover, a network unit is introduced, which extends each subsystem in order to realise the cooperative mode between them without a coordinator. They detect, initiate and ensure cooperative behaviour. A simulation demonstrates a flexible manufacturing system, which results by applying the proposed method to autonomous controlled subsystems.
