主权项

1. An elevator installation modernization method comprising:
placing a destination call control at an elevator installation, the destination call control being configured to generate start floor signals and destination floor signals based at least in part on a destination call signal or an identification code; connecting the destination call control with an existing elevator control using an existing serial maintenance interface of the existing elevator control, such that the destination call control is configured to provide the start floor signals and the destination floor signals to the existing elevator control through the serial maintenance interface; functionally separating a group control from the elevator control; and logging off the elevator control from the group control by transmitting at least one logging-off signal from the destination call control to the existing elevator control using a communication link.
