The composition of mechatronic systems of traditional mechanical and electrical components are discussed, however the application of "smart" devices with incorporation of sensors, actuators, and computer control systems are investigated for the industrial applications. The integration of mechanical systems and microelectronics opens many new possibilities for process design and automatic functions in industrial electronics. After analysis the mutual interrelations between the design of the mechanical system and application of sufficient digital electronic system the different ways of integration within mechatronic systems and the resulting properties are described. The information processing organisation in multi level, ranging from low level control through supervision to general process management. The example of intelligent control system application are described.
