ET200sIM151-7CPU是ET200s分布式I/O系统的一部分，具有何S7-314相近的功能，其防护等级为IP20，ET200sIM151-7CPU接口模块是一个＂智能预处理单元＂（１slave）,它能让你实现完美的分布式控制。
一个具有ET200sIM151-7CPU的ET200s站点能够控制一个工艺单元，而且也可以用作一个单机CPU,通过连接一个主站接口模块ET 200s IM 151-7 CPU可以作为一个DP主站使用。
此次发布的ET 200s IM 151-7 CPU进一步增加了工作内存，至此，ET 200s IM 151-7 CPU的工作内存已经从24k增加到了96K，这样，使ET200sIM151-7CPU可以完成更加复杂的控制任务，下述为该产品的技术参数。
