Design and realization of elevator control system based on PLC
The application of S7 200 series Programmable Logic Controller (PLC) in the three story elevator control system is introduced in this paper,and hardware and software design of the control system using PLC controller are given. Control system design plan,design process,system composition of three story based on PLC are proposed,and a complete program of the elevator control system is designed,finally,the functions of system are validated on the three story elevator model. From the results,it is shown that the system has function of no driver control,and is a high degree of security and reliability of the elevator control system.
