1、西门子PLC在电梯群控系统中的应用摘要本文介绍了PLC控制的四层电梯模型的构成、主要功能、PLC的I/O接口分配、PLC的编程方法及对电梯系统的程序设计等。通过对电梯控制系统的程序设计，实现了电梯的开关门控制以及在电梯运行方式下电梯的呼叫显示、上下行、起动、延时关门、平层、停靠开门、信号排队、顺向截梯和报警等控制功能。通过对软件程序的编译、硬件的连接以及电梯模型与PLC控制系统的联调，使得控制系统在电梯模型运行过程中直观的体现出来，实现了对电梯功能的控制。本次设计主要将可编程序控制器（PLC）和计算机应用到电梯的控制系统中去，以两台四层电梯为例来完
2、成电梯PLC群控制系统的总体设计方案、组成及模块化程序设计。本课题的主要实现的功能：全集选控制、保持开门时间的自动控制、本层厅外开门、全自动状态下门开到位后会立即关门、开门按钮开门、换站停靠、错误指令取消、接停靠、待梯时轿内照明和风扇自动断电、层楼显示字符设置、显示器、火灾紧急返回运行、超载保护、门缝防夹保护、双刹车保护。关键词：PLC功能群控组态王58ApplicationofSiemensPLCintheElevatorGroupControlsystemabstractThispaperintroducesthePLC-controlledm
