The integrated transmission of information and power is a very important point of interest and a demand of many industrial bus system users. First results of such bus systems especially for simple binary sensors are known. The main task of this research activities is the integrated power transmission (IPT) in CAN systems even for analogue sensors with features of signal conditioning and data pre- processing. The paper presents a solution of such a bus node. Beside the conventional data processing a power management is necessary. In relation with the abilities of the node two methods of integrated transmission of information and power will be explained. The advantages and disadvantages for several application fields will be shown. Finally the results of the investigation of dynamic behaviour, error behaviour, and power capacity will be summarized.
