Abstract
Abstract An elevator control system includes an ROM device having control data common to all elevator cars stored therein, and a setting device having a plurality of switches which are selectively closed and opened to designate the ordinal binary numbers of floors of a building served by an associated elevator car. When the building has many floors, the setting device may similarly designate the ordinal binary number of the lower ten floors and those of the remaining floors are additionally stored in the ROM device.
