Powerline communication in a field plane

Present a consequential standardization becomes generally accepted for fieldbus networks. Each of the available network solutions is shaped by a typical communication standard, that optimally employable is for special application areas. Existing industrial solutions establish themselves with it more and more strongly and hardly stilt appear it new networks. By optimization of the network structures and expansion of the application width innovations are advanced. The realizations of new designs of the physical interface of field bus networks contribute to it particularly. With the aim, through new circuits the original bus node interfaces to expand, the application-width of the respective field bus is rising. For the data transfer the field bus networks use different physical media. To the expansion of the utilization some research projects concentrates of the bus integrated power supply. Important technical and economic effects through simultaneous transfer of information and energy over the same wire can be achieved.
