PURPOSE:To improve additional value and reliability of an elevator by dividing communication data between micro-computers into the control data of fundamental function of the elevator and the out-of-control data of additional data. CONSTITUTION:When certain control data are necessary to transmit from a micro-computer 10 to a micro-computer 20, the computer 10 transmits corresponding data 8-bit of data class through the first communication system, that is, ACIA(Asynchronous Commnunication Interface Adapter) 14A, and then transmits data 8-bit of data content. On the other hand, the computer 20 receives these data through ACIA 24A, and can understand the meaning of the data from the class and content of the data. When the data to be communicated are out-of- control data, the data are transmitted and received through the second communicating system. |
