隨著PLC在工業控制中的推廣普及，PLC產品的種類越來越多，其結構型號、性能、容量、指令系統、編程方法等各不相同，適用場合也各有側重。因此，合理選擇 PLC，對于提高PLC在控制系統中的應用有著重要作用。

一、機型的選擇

我國市場上流行的有如下幾家PLC產品：

1．施耐德公司，包括早期天津儀表廠引進莫迪康公司的產品，目前有Quantum、Premium、Momentum等產品；

2．羅克韋爾公司（包括AB公司）PLC產品，目前有SLC、Micro Logix、Control Logix等產品；

3．西門子公司的產品，目前有SIMATIC S7-400/300/200系列產品；

4．GE公司的產品；

5．日本歐姆龍、三菱、富士、松下等公司產品，其中使用較多的是三菱公司F1、F2、FX2等系列產品。
