描述

功能强

PLC应用微电子技术和微计算机，简单型式都具有逻辑、定时、计数等顺序控制功能。基本型式再加上模拟I/O、基本算术运算、通信能力等。复杂型式除了具有基本型式的功能外，还具有扩展的计算能力、多级终端机制、智能I/O、PID调节、过程监视、网络通信能力、远程I/O、多处理器和高速数据处理能力。

4、编程方便

PLC适用针对工业控制的梯形图、功能块图、指令表和顺序功能表图(SFC)编程，不需要太多的计算机编程知识。新的编程工作站配有综合的软件工具包，并可在任何兼容的个人计算机上编程。

5、适应工业环境

PLC的技术条件能在一般高温、振动、冲击和粉尘等恶劣环境下工作，能在强电磁干扰环境下可靠工作。这是PLC产品的市场生存价值。

6、安装、维修简单

与计算机系统相比，PLC安装不需要特殊机房和严格的屏蔽。使用时只要各种器件连接无误，系统便可工作，各个模件上设有运行和故障指示装置，便于查找故障，大多数模件可以带电插拔，模件可更换，使用户可以在短的时间内查出故障，并排除，大限度地压缩故障停机时间，使生产迅速恢复。然后再对故障模件进行修复，这对大规模生产场合尤为适宜。

一些PLC外壳由可在不良工作环境下工作的合金组成，结构简单，上面带有散热槽，在高温下，该外壳不像塑料制品那样变形，还可抗无线电频率(RF高频)电磁干扰、防火等。

7、运行速度快
