In all machines, test benches and other automated systems, the input and output devices such as sensors, terminals, drives and cameras must be connected to one another. Fast and permanently reliable communication is required. The best camera is useless if it cannot transport its data to the controller. Even if the handling of the communication takes place in the background, a perfect solution to this task is indispensable for the function: communication streams must be allocated or parts of the system must be dynamically decoupled; a section may place special requirements on the transmission since it is supposed to run via optical fibers, for example. In such cases, a diverse portfolio of infrastructure components is essential.
