S7-300自动化系统采用模块化设计。它拥有丰富的模块，且这些模块均可以独立地组合使用。

一个系统包含下列组件：

• CPU：
  不同的 CPU 可用于不同的性能范围，包括具有集成 I/O 和对应功能的 CPU 以及具有集成 PROFIBUS DP、PROFINET 和点对点接口的 CPU。

• 用于数字量和模拟量输入/输出的信号模块 (SM)。

• 用于连接总线和点对点连接的通信处理器 (CP)。

• 用于高速计数、定位（开环/闭环）及 PID 控制的功能模块（FM）。

根据要求，也可使用下列模块：

• 用于将 SIMATIC S7-300 连接到 120/230 V AC 电源的负载电源模块(PS)。

• 接口模块 (IM)，用于多层配置时连接中央控制器 (CC) 和扩展装置 (EU)。
  通过分布式中央控制器 (CC) 和 3 个扩展装置 (EU)，SIMATIC S7-300 可以操作多达 32 个模块。所有模块均在外壳中运行，并且无需风扇。

• SIPLUS 模块可用于扩展的环境条件：
  适用于 -25 至 +60℃ 的温度范围及高湿度、结露以及有雾的环境条件。防直接日晒、雨淋或水溅，在防护等级为 IP20 机柜内使用时，可直接在汽车或室外建筑使用。不需要空气调节的机柜和 IP65 外壳。
