1）PPI协议：西门子专为S7-200开发的通讯协议

　　 2）MPI协议：不完全支持，只能作从站

　　 3）自由口模式：由用户自定义的通讯协议，用于与其他串行通讯设备通讯（如串行打印机等）。

　　 S7-200编程软件Micro/WIN提供了通过自由口模式实现的通讯功能：

　　 1）USS指令库：用于S7-200与西门子变频器（MM4系列、SINAMICS G110和老的MM3系列）

　　 2）Modbus RTU指令库：用于与支持Modbus RTU主站协议的设备通讯

　　 S7-200 CPU上的两个通讯口基本一样，没有什么特殊的区别。它们可以各自在不同的模式、通讯速率下工作；它们的口地址甚至也可相同。分别连接到CPU上两个通讯口上的设备，不属于同一个网络。S7-200 CPU不能充当网桥的作用。

RS触发器指令  RS触发器指令的基本功能与置位指令S和复位指令R的功能相同。

   置位优先（SR）触发器的置位信号SI和复位信号R同时为1时，输出OUT信号为1。

    复位优先（RS）触发器的置位信号S和复位信号RI同时为1时，输出OUT信号为0。

逻辑设计法是以布尔代数为理论基础，根据生产过程中各工步之间的各个检测元件（如行程开关、传感器等）状态的变化，列出检测元件的状态表，确定所需的中间记忆元件，再列出各执行元件的工序表，然后写出检测元件、中间记忆元件和执行元件的逻辑表达式，再转换成梯形图。该方法在单一的条件控制系统中，非常好用，相当于组合逻辑电路，但和时间有关的控制系统中，就很复杂。

下面将介绍一个交通信号灯的控制电路。

【例】用PLC构成交通灯控制系统。

（1）控制要求：如图1所示，起动后，南北红灯亮并维持25s。在南北红灯亮的同时，东西绿灯也亮，1s后，东西车灯即甲亮。到20s时，东西绿灯闪亮，3s后熄灭，在东西绿灯熄灭后东西黄灯亮，同时甲灭。黄灯亮2s后灭东西红灯亮。与此同时，南北红灯灭，南北绿灯亮。1s后，南北车灯即乙亮。南北绿灯亮了25s后闪亮，3s后熄灭，同时乙灭，黄灯亮2s后熄灭，南北红灯亮，东西绿灯亮，循环。

（2）I/O分配

输入                        输出

起动按钮：I0.0            南北红灯：Q0.0     东西红灯：Q0.3

      南北黄灯：Q0.1     东西黄灯：Q0.4

      南北绿灯：Q0.2     东西绿灯：Q0.5

               南北车灯：Q0.6     东西车灯：Q0.7

（3）程序设计

   根据控制要求首先画出十字路口交通信号灯的时序图，如图2所示。      

图2   十字路口交通信号灯的时序图

   根据十字路口交通信号灯的时序图，用基本逻辑指令设计的信号灯控制的梯形图如图3所示。分析如下：

   首先，找出南北方向和东西方向灯的关系：南北红灯亮（灭）的时间=东西红灯灭（亮）的时间，南北红灯亮25S（T37计时）后，东西红灯亮30S（T41计时）后。

   其次，找出东西方向的灯的关系：东西红灯亮30S后灭（T41复位）→东西绿灯平光亮20S（T43计时）后→东西绿灯闪光3S（T44计时）后，绿灯灭→东西黄灯亮2S（T42计时）。

   再其次，找出南北向灯的关系：南北红灯亮25S（T37计时）后灭→南北绿灯平光25S（T38计时）后→南北绿灯闪光3S（T39计时）后，绿灯灭→南北黄灯亮2S（T40计时）。

   最后找出车灯的时序关系：东西车灯是在南北红灯亮后开始延时（T49计时）1S后，东西车灯亮，直至东西绿灯闪光灭（T44延时到）；南北车灯是在东西红灯亮后开始延时（T50计时）1S后，南北车灯亮，直至南北绿灯闪光灭（T39延时到）。

  根据上述分析列出各灯的输出控制表达式：

东西红灯：Q0.3=T37                     南北红灯Q0.0=M0.0·T3

东西绿灯：Q0.5=Q0.0·T43+T43·T44·T59     南北绿灯Q0.2=Q0.3·T38+T38·T39·T59

东西黄灯：Q0.4=T44·T42                  南北黄灯Q0.1=T39·T40

    东西车灯：Q0.7=T49·T44                  南北车灯Q0.6=T50·T39
