Evolutionary trends of embedded systems

This paper deals with communication possibilities of embedded systems and their environment, remote administration and diagnostic. Sphere embedded systems nowadays contain both simple and dedicated implementations and relatively sophisticated systems (functionally and computationally). Its application software runs on e.g. real-time operating systems and the surrounding communication is provided by a classical metallic connection (RS485, CAN, Ethernet) or via more now steadily used wireless connection (Bluetooth, WiFi, GSM/GPRS), alternatively with usage fiber optic and combination of these ways. Modern trends lean towards migration of computationally demanding application software from control rooms closer to controlled machines. The procedural controlling software is steadily closer (sometimes even build-in) directly to actuators of machines and the controlling rooms with color knead animations of controlled technology are on the one hand connected via Ethernet up to controlled process and on the other hand up to information system.
