在讨论调用块前先介绍一下OB1块——主循环块，不能改名或删除，它是由操作系统循环调用，可以访问其他的S7程序块，它包括自身程序和其他块的调用。所以，当我们编辑好一个块以后，如FC1，为了让新块集成在CPU中的循环程序中，必须在OB1中调用。即在OB1中CALL F1。 子程序（新块FC 1）执行的条件有以下三个：已经下载到PLC中，必须在OB1调用，PLC处于运行状态。 下载到实际的PLC时，我们可以选择所有块或其中的一个或几个，再Download到PLC中。
程序的执行过程：当PLC得电或从STOP切换到RUN模式，CPU会执行一次全启动（使用OB100）在全启动期间，操作系统清除非保持位存储器、定时器和计数器，删除中断堆笺和块堆笺，复位所有保存的硬件中断，并启动扫描循环监视时间。
CPU的循环操作包括三个主要部分：CPU检查输入信号的状态并刷新过程影象输入表（PII..）；执行用户程序，也就是OB1中的程序及一些事件（中断等）；把过程输出影象输出表（PIQ）写到输出模块。上面所提到的PII/PIQ是CPU中特定的存储器，用来保存输入模块/输出模块的信号，在用户程序中检查时，可以保证在一个扫描周期内为同样的信号状态。
