LONWORKS and AS-i devices for building and facility networks

摘要

In building automation and facility management, it has become an important subject to reduce the total cost for the system development to maintenance by structuring a total system based on an open network. The LONWORKS and AS i bus regarded as networks suitable to this need have already diffused in Europe and USA, and are supposed to expand rapidly also in Japan in future. This paper describes their features and available devices from Fuji Electric.
