【正文】 ider that the system’s function can be expanded in the future .Ｃ 200HE series PLC ,whose perfect function and strong reliability, can meet these demands at present. Moreover, input and output devices are needed in elevator control system, besides the PLC, system’s major control device. Part of signal hookups of the elevator electric control system is shown in . The control cabi is the control center, from which we can send out various control mands. The control cabi often was installed in the elevator room .The electric devices and signal systems, for example the contactors, relays, capacitances, resistors, rectifiers and transformers etc., are centralized in the control cabi. The Power of the control cabi was imported from the chief power of the elevator room. This power was also introduced into control panel by soft cables and was linked with each control buttons. The power lines which was derived from control cabi was delivered to tow electric motors. Others control lines and signal lines were separately sent to each floor junction Ⅳ . Program design The design includes two parts: hardware and hardware design is the base of software. Considering that the control demands are relatively plex, we design the programs separately according to the control function. Furthermore, we follow the principle as follows: When the elevator is ascending, the ascending demands are prior to other demands。 elevator control system。Application of PLC in the Elevator Control System of Intelligence Building Abstract: The paper mainly discusses one subsystem of intelligence building system: the elevator control system. The PLC strong ability in interference and so on makes the elevator industry one after another to apply the PLC to the elevator control system in order to replace the relay being used in traditional elevator control system. The Application of PLC in the Elevator control system reduces the breakdown rate and efficiently improves the operating reliability of the elevator with safety .The structure of system is also simple and tightly working principle of the elevator control system is: The spot control information is send into the ＰＬＣ from the customer input devices firstly, then the PLC control cabi is required to send out the control signal to drive the equipments according to the system demands. The elevator can then proceed the homologous action according to the control reque
