6ES7231-5PD30-0XB0 上亿佳不后悔
西门子S7-400同300的区别主要在于热启动(wrst)这一部分，其他基本一样。它还有一个外部的电池电源接口，当在线更换电池时可以向ram提供后备电源。编程设备主要有pg720pg740pg760——可以理解成装有编程软件的手提电脑;也可以直接用安装有step7(siemens的编程软件)的pc来完成。而实现通讯(要编程要和plc的cpu通讯上)的要求主要在于接口：1.可以在pc上装cp5611卡——上面有mpi口，可用电缆直接连接。2.加个pc适配器，把mpi口转换成rs-232口后接到pc上。3.plc加cp343卡，使它具有以太网口。
西门子S7-1200 小型可编程控制器
西门子SIMATIC S7-1200是一款紧凑型、模块化的PLC，可完成简单逻辑控制、逻辑控制、HMI 和网络通信等任务。
单机小型自动化系统的*解决方案。 对于需要网络通信功能和单屏或多屏HMI的自动化系统，易于设计和实施。
具有支持小型运动控制系统、过程控制系统的应用功能
新的模块化SIMATIC S7-1200控制器是我们新推出产品的核心，可实现简单却度的自动化任务。SIMATIC S7-1200控制器实现了模块化和紧凑型设计，功能强大、投资并且适合应用。
可扩展性强、灵活度的设计，可实现标准工业通信的通信接口以及一整套强大的集成技术功能，使该控制器成为完整、全面的自动化解决方案的重要组成部分。
使用集成的新工程组态 SIMATICSTEP 7 Basic，并借助 SIMATIC WinCC Basic 对 SIMATICS7-1200 进行编程。SIMATIC STEP 7 Basic的设计理念是直观、易学和易用。这种设计理念可以使您在工程组态中实现效率。一些智能功能，例如直观编辑器、拖放功能和“IntelliSense”（智能感知）工具，能让您的工程进行的更加迅速。这款新软件的体系结构源于对未来创新的不断追求，西门子在软件开发领域已经有很多年的经验，SIMATIC STEP 7 的设计是以未来为导向的 。
SIMATIC S7-1200 系统有五种不同模块，分别为 CPU 1211C、CPU 1212C 、 CPU1214C、CPU1215C和CPU1217C。其中的每一种模块都可以进行扩展，以满足您的系统需要。可在任何 CPU的前方加入一个信号板，轻松扩展数字或模拟量 I/O，不影响控制器的实际大小。可将信号模块连接至 CPU的右侧，扩展数字量或模拟量 I/O 容量。CPU 1212C 可连接 2 个信号模块，CPU 1214C、CPU1215C和CPU1217C可连接 8 个信号模块。，所有的 SIMATIC S7-1200 CPU 控制器的左侧均可连接多达3 个通讯模块，便于实现端到端的串行通讯。
