Most functions of conventional elevator systems are performed by a single central control unit located in a machine room. However, such designs limit the possibilities for adding new functions and improving system performances. This paper describes a newly developed data network system in which microprocessor modules located in the machine room, cars, and halls are linked together by a serial-transmission network. Network distributed design has made it possible to increase the system sophistication and performances.
