问：当我硬件配置的时候，CPU会识别PS307 5A与10A吗？如果我组态的时候是5A，然后我实际用的是10A的，请问CPU会报错吗？

答：当我硬件配置的时候，CPU会识别PS307 5A与10A吗？如果我组态的时候是5A，然后我实际用的是10A的，请问CPU会报错吗？
-----------这个CPU不会去识别的，因为PS307与CPU根本就没有数据线线连接。
学自动化的，整天听别人说起PLC，究竟什么是PLC呢？PLC就是可编程控制器。PLC可编程序控制器：PLC英文全称Programmable Logic Controller ,中文全称为可编程逻辑控制器，定义是:一种数字运算操作的电子系统，专为在工业环境应用而设计的。它采用一类可编程的存储器，用于其内部存储程序，执行逻辑运算,顺序控制，定时，计数与算术操作等面向用户的指令，并通过数字或模拟式输入/输出控制各种类型的机械或生产过程。
       二十世纪六十年代美国开始推出可编程逻辑控制器（Programmable Logic Controller，PLC），用来取代传统继电器控制装置，从那时起，PLC技术快速发展，在全世界范围内得到了广泛的应用。PLC的功能也不断完善。随着计算机技术、信号处理技术、控制技术网络技术的不断发展和用户需求的不断提高，PLC的功能也不断完善，PLC在开关量处理的基础上增加了模拟量处理和运动控制等功能。今天的PLC不再局限于逻辑控制，在运动控制、过程控制等领域也发挥着十分重要的作用。
      PLC作为离散控的制的首选产品，PLC在二十世纪八十年代至九十年代得到了迅速发展，全世界PLC使用年增长率保持在20%～30%。随着工厂自动化程度的不断提高和PLC市场容量基数的不断扩大，近年来PLC在工业发达国家的增长速度放缓。但是，在中国等发展中国家PLC的增长十分迅速。综合相关资料，2004年全球PLC的销售收入为100亿美元左右，在自动化领域占据着十分重要的位置。
　　 PLC是由摸仿原继电器控制原理发展起来的，二十世纪七十年代的PLC只有开关量逻辑控制，首先应用的是汽车制造行业。它以存储执行逻辑运算、顺序控制、定时、计数和运算等操作的指令；并通过数字输入和输出操作，来控制各类机械或生产过程。用户编制的控制程序表达了生产过程的工艺要求，并事先存入PLC的用户程序存储器中。运行时按存储程序的内容逐条执行，以完成工艺流程要求的操作。PLC的CPU内有指示程序步存储地址的程序计数器，在程序运行过程中，每执行一步该计数器自动加1，程序从起始步（步序号为零）起依次执行到最终步（通常为END指令），然后再返回起始步循环运算。PLC每完成一次循环操作所需的时间称为一个扫描周期。不同型号的PLC，循环扫描周期在1微秒到几十微秒之间。PLC用梯形图编程，在解算逻辑方面，表现出快速的优点，在微秒量级，解算1K逻辑程序不到1毫秒。它把所有的输入都当成开关量来处理，16位（也有32位的）为一个模拟量。大型PLC使用另外一个CPU来完成模拟量的运算。把计算结果送给PLC的控制器。
　　相同I/O点数的系统，用PLC比用DCS，其成本要低一些（大约能省40%左右）。PLC没有专用操作站，它用的软件和硬件都是通用的，所以维护成本比DCS要低很多。一个PLC的控制器，可以接收几千个I/O点（最多可达8000多个I/O）。如果被控对象主要是设备连锁、回路很少，采用PLC较为合适。PLC由于采用通用监控软件，在设计企业的管理信息系统方面，要容易一些。
　　近10年来，随着PLC价格的不断降低和用户需求的不断扩大，越来越多的中小设备开始采用PLC进行控制，PLC在我国的应用增长十分迅速。随着中国经济的高速发展和基础自动化水平的不断提高，今后一段时期内PLC在我国仍将保持高速增长势头
通用PLC应用于专用设备时可以认为它就是一个嵌入式控制器，但PLC相对一般嵌入式控制器而方具有更高的可靠性和更好的稳定性。实际工作中碰到的一些用户原来采用嵌入式控制器，现在正逐步用通用PLC或定制PLC取代嵌入式控制器，PLC产业一定会有一个美好的未来。          咨询热线：18150695049
