SIEMENS 16114-171 复杂的控制系统不仅I／O点数多，功能表图也相当复杂，除包括前面介绍的功能表图的基本结构外，还包括跳步与循环控制，而且系统往往还要求设置多种工作方式，如手动和自动（包括连续、单周期、单步等）工作方式。手动程序比较简单，一般用经验法设计，自动程序的设计一般用顺序控制设计法。
1．跳步
如图5-34所示用状态器来代表各步，当步S31是活动步，并且X5变为“1”时，将跳过步S32，由步S31进展到步S33。这种跳步与S31S32 S33等组成的“主序列”中有向连线的方向相同，称为正向跳步。当步S34是活动步，并且转换条件 时，将从步S34返回到步S33，这种跳步与“主序列”中有向连线的方向相反，称为逆向跳步。显然，跳步属于选择序列的一种特殊情况。
图5-34 含有跳步和循环的功能表图
2．循环
在设计梯形图程序时，经常遇到一些需要多次重复的操作，如果一次一次地编程，显然是非常繁琐的。我们常常采用循环的方式来设计功能表图和梯形图，如图5-34所示，假设要求重复执行10次由步S33和步S34组成的工艺过程，用C0控制循环次数，它的设定值等于循环次数10。每执行一次循环，在步S34中使C0的当前值减1，这一操作是将S34的常开触点接在C0的计数脉冲输入端来实现的，当步S34变为活动步时，S34的常开触点由断开变为接通，使C0的当前值减1。每次执行循环的**后一步，都根据C0的当前值是否为零来判别是否应结束循环，图中用步S34之后选择序列的分支来实现的。假设X4为“1”，如果循环未结束，C0的常闭触点闭合，转换条件 满足并返回步S33；当C0的当前值减为0，其常开触点接通，转换条件 满足，将由步S34进展到步S35。
在循环程序执行之前或执行完后，应将控制循环的计数器复位，才能保证下次循环时循环计数。复位操作应放在循环之外，图5-34中计数器复位在步S0和步S25显然比较方便。
