Abstract: An elevator control data intercommunication programmer including a main board equipped with master and slave CPUs for controlling the operation of the elevator, EEPROMs for providing operation data to the CPUs, a DSP for controlling vector operation of the elevator's motor, and a data communication port for data communication with an external microprocessor unit. Through the data communication port, data can be programmed in the EEPROMs, so that the elevator operation data (parameters) in the memory of a failed CPU can be copied to another CPU for replacement.
