为什么工控界更信任PLC，选择PLC作为工控的核心部件呢，主要是由于PLC的以下五个特点：

1. 可靠性高，抗干扰能力强

无触点控制：故障率少；

硬件措施：屏蔽、滤波、隔离；

软件措施：故障检测、信息保护和恢复、警戒时 钟（死循环报警）、程序检验

2. 使用灵活，通用性强

产品系列化，硬件结构模块式，可灵活选用；

软接线逻辑使得PLC能简单轻松的实现各种不同的控制任务，且系统设计周期短。

3. 编程方便，易于掌握

     采用与继电器电路极为相似的梯形图语言，直观易懂， SFC 功能图，使编程更简单方便。

4. 接口简单，维护方便

    可直接与现场强电设备相连接，接口电路模块化。

有完善的自诊断及监视功能，便于查出故障原因，并迅速处理。

5. 功能完善，性价比高

     除逻辑控制，定时计数，数字运算外，配合特殊功能模块还可以实现点位控制， PID 运算，过程控制，数字控制等功能，还可与上位机通信，远程控制等
