电梯控制程序；电气控制系统采用可编程控制器占很大比例，由于篇幅有限，本应用程序仅就PLC在这一领域的应用做一个简单分析，而实际应用程序是比较复杂的、必须经过严格的实际训练方可进行实际电梯的程序维护。-Elevator control procedures　electrical control system uses a large proportion of the programmable controller, because of space limitations, this application only in respect of the application of PLC in this field to make a simple analysis, but the actual application is more complex and must undergo a rigorous The actual training program before the actual elevator maintenance.
