1.       用时序图分析图4-42所示梯形图的工作原理。

2.       若X0信号如图“”所示，请再分析该梯形图的工作原理。

例题分析

          (1)       X0信号使Y0及T0线圈接通。

          (2)       T0线圈接通1S后，T0的常开触点闭合,常闭触点断开。T0的常开触点接通Y1及T1线圈，此过程均在一个扫描周期内完成，该扫描周期直至ED结束（注意：PLC是循环扫描工作方式）。

           (3)        在T0触点动作的下一个周期，T0的常闭触点使Y0失电,Y0常开触点断开使T0线圈失电,使 T0常开触点、常闭触点同时复位。

图4-42  例题4-22梯形图

                 图4-43  例题4-22时序图

          (4)       T1线圈接通1S后，T1的常开、常闭触点均动作。

          (5)       在下一个扫描周期T1的常开触点使Y0接通，Y0的常开触点又接通T0线圈。如此循环至X1信号到来使全系统复位。根据上述分析画出如图4-43所示的时序图，因梯形图中Y0、Y2、Y4、Y6、均为并联关系，时序图中只画了Y0的图形，Y1、Y3、T5、T7亦如此。

此题，是一个典型的霓虹灯控制程序，通过分析此题应更进一步理解PLC的循环扫描工作方式。

当X0为“”时在第③过程中只能将Y0关断一个扫描周期，实际中裸眼观察结果是Y0、Y2、Y4、Y6常亮。
