PROBLEM TO BE SOLVED: To provide an elevator system that is resistant to noise and can reduce cost by reducing a man-hour for wiring. SOLUTION: As an open-network actuator-sensor interface (AS-i) is applied to a conventional elevator system, by way of example, an AS-i master 12 is arranged between a programmable controller (PLC) 11, and a floor unit 2 and a car unit 3, and at least one AS-i slave is arranged in each of a floor control part 21 and a car control part 31, which can establish a system construction that is resistant to noise and reduces a man-hour for wiring. Use of a decoding circuit or an encoding circuit for input/output about the floor control part 21 and the car control part 31 can save further wiring.
