描述
SEW-DIP
PLC是由继电器逻辑系统发展而来，主要用在离散制造、工序控制，初期主要是代替继电器控制系统，侧重于开关量顺序控制方面。
近年来随着微电子技术、大规模集成电路技术、计算机技术和通信技术等的发展，PLC在技术和功能上发生了飞跃。在初期逻辑运算的基础上，增加了数值运算、闭环调节等功能，增加了模拟量和PID调节等功能模块；运算速度提高，CPU的能力赶上了工业控制计算机；通信能力的提高发展了多种局部总线和网络(LAN)，因而也可构成为一个集散系统。特别是个人计算机也被吸收到PLC系统中。
PLC在过程控制的发展将是一智能变送器和现场总线，暨向下拓展功能，开放总线。由于PLC和计算机属于两类产品，经过几十年的发展都形成了自身的装置特点和软件工具。实际上的区别继续存在。
PLC用编程器或计算机编程，编程语言是梯形图、功能块图、顺序功能表图和指令表等。集散系统自身或用计算机结构形成组态构成开发系统环境。特别提出的是与STD总线工控机的区别，无论从维修、安装和模件功能都很相似。PLC更适用于黑模式下运行，但在线运行时若要进行较大的程序修改，其能力略逊于STD工控机，但是从开关量控制而言，PLC的性能优于STD工控机。
总的来说，在选择控制器时，首先要从工程要求、现场环境和经济性等方面考虑。没有什么控制器绝对完善，也没有哪种产品绝对差，只能说选择更适用的产品。
