為什么工控界更信任PLC，選擇PLC作為工控的核心部件呢，主要是由于PLC的以下五個特點：

1. 可靠性高，抗干擾能力強

無觸點控制：故障率少；

硬件措施：屏蔽、濾波、隔離；

軟件措施：故障檢測、信息保護和恢復、警戒時 鐘（死循環報警）、程序檢驗

2. 使用靈活，通用性強

產品系列化，硬件結構模塊式，可靈活選用；

軟接線邏輯使得PLC能簡單輕松的實現各種不同的控制任務，且系統設計周期短。

3. 編程方便，易于掌握

     采用與繼電器電路極為相似的梯形圖語言，直觀易懂， SFC 功能圖，使編程更簡單方便。

4. 接口簡單，維護方便

    可直接與現場強電設備相連接，接口電路模塊化。

有完善的自診斷及監視功能，便于查出故障原因，并迅速處理。

5. 功能完善，性價比高

     除邏輯控制，定時計數，數字運算外，配合特殊功能模塊還可以實現點位控制， PID 運算，過程控制，數字控制等功能，還可與上位機通信，遠程控制等
