s7-200的三种程序组织单位（POU）指主程序、子程序和中断程序。STEP 7-Micro/WIN为每个控制程序在程序编辑器窗口提供分开的制表符，主程序总是个制表符，后面是子程序或中断程序。
一个项目（Project）包括的基本组件有程序块、数据块、系统块、符号表、状态图表、交叉引用表。程序块、数据块、系统块须到PLC，而符号表、状态图表、交叉引用表不到PLC。
程序块由可执行代码和注释组成，可执行代码由一个主程序和可选子程序或中断程序组成。程序代码被编译并到PLC，程序注释被忽略。
² ² 在“指令树”中 右击“程序块”图标可以插入子程序和中断程序。
数据块由数据（包括初始内存值和常数值）和注释两部分组成。
数据被编译后，到可编程控制器，注释被忽略。
系统块用来设置系统的参数，包括通信口配置信息、保存范围、模拟和数字输入过滤器、背景时间、表、脉冲截取位和输出表等选项。系统块如图1所示。
² ² 单击“浏览栏”上的“系统块”按钮，或者单击“指令树”内的“系统块”图标，可查看并编辑系统块。
系统块的信息须到可编程控制器，为PLC提供新的系统配置
