Recent trends and issues of device integration standardization

Although there are many fieldbus technologies, the device integration of different fieldbuses has been a problem. In the device integration standardization, the generic application service interfaces are going to be standardized for integrating multi-device technologies. This paper gives an overview of the generic application service interface for the multi-device technologies integration. We show the device capability profiling method for the generic application service interface. New standard of the generic application service interface for the power drive system is explained. Then, we show the recent trends and issues of the device integration standardization.
