Abstract
As society continues to develop, the higher buildings are more and more . The elevator became a high-rise building to house the equipment. At present most of the lift elevator control system logic control system using PLC logic control Circuit. Using this control system has greatly enhanced the reliability of the lift, maintainability and flexibility to extend the service life of the elevator at the same time shorten the development cycle. PLC in the elevator control system is used in most of medium such as the Mitsubishi PLC control system design
FPX PLC is the recently introduced small PLC, its function is very powerful. This paper will be used in Matsushita PLC logic control for five elevator, the elevator control system has drivers automatically operate the functions of control and has set the election, the election set down, down-election, re-fault opened the door. Fault detection and so on.
