一般是基本指令占54%(其中輸入指令占17%，輸出指令13%，邏輯運算指令21%，定時器輸出3%)，數據處理指令占39%（其中傳送指令占25%，四則函數運算指令，比較指令6%），其它指令7%。仍以三菱電機的小Q系列為例，其中的Q25HCPU的PCmix值是10.3，比A2UHCPU-S1快5倍（為2.0），比A2SHCPU快20倍多(PCmix值為0.5)。隨著PLC的功能擴展，運算指令、文字處理指令、通信指令等用的越來越多，各種指令的使用頻率也會發(fā)生一定的變化，PCmix值的計算也會有所變化。這里順便提一下，之所以要多次舉三菱電機為例，是因為它的PLC的市場份額占日本的50%以上，為日本的大PLC供應廠商，因而具有相當的典型性。同時，通過軟件技術提升PLC專用操作系統(tǒng)的水平，實現了事件中斷的高速響應（200微秒）功能，高速計數功能，0.5毫秒（三菱電機的小Q系列PLC）、甚至0.2毫秒（橫河電機的的FA-M3系列PLC）的恒定掃描時間功能。
