　　plc產品種類繁多，其規格和性能也各不相同。對plc的分類，通常根據其結構形式的不同、功能的差異和i/o點數的多少等進行大致分類。

　　1.按結構形式分類

　　根據plc的結構形式，可將plc分為整體式和模塊式兩類。

　　(1)整體式plc 整體式plc是將電源、cpu、i/o接口等部件都集中裝在一個機箱內， 具有結構緊湊、體積小、價格低的特點。小型plc一般采用這種整體式結構。整體式plc由不同i/o點數的基本單元(又稱主機)和擴展單元組成。基本單元內有cpu、i/o接口、與i/o擴展單元相連的擴展口，以及與編程器或eprom寫入器相連的接口等。擴展單元內只有i/o和電源等，沒有cpu。基本單元和擴展單元之間一般用扁平電纜連接。整體式plc一般還可配備特殊功能單元，如模擬量單元、位置控制單元等，使其功能得以擴展。
