一、 实验目的
1、 通过对工程实例的模拟，熟练地掌握PLC的编程和程序调试方法。
2、 进一步熟悉PLC的I/O连接。
3、 熟悉三层楼电梯采用轿厢内外按钮控制的编程方法。
二、控制要求
电梯由安装在各楼层厅门口的上升和下降呼叫按钮进行呼叫操纵，其操纵内容为电梯运行方向。电梯轿厢内设有楼层内选按钮S1～S3，用以选择需停靠的楼层。L1为一层指示、L2为二层指示、L3为三层指示，SQ1～SQ3为到位行程开关。电梯上升途中只响应上升呼叫，下降途中只响应下降呼叫，任何反方向的呼叫均无效。例如，电梯停在一层，在三层轿厢外呼叫时，必须按三层上升呼叫按钮，电梯才响应呼叫（从一层运行到三层），按三层下降呼叫按钮无效；反之，若电梯停在三层，在一层轿厢外呼叫时，必须按一层下降呼叫按钮，电梯才响应呼叫，按三层上升呼叫按钮无效，依此类推。
三、 编制梯形图并写出程序，参考程序 表6-10-1所示
