PLC的基本知識及PLC的優勢
|
可編程控制器是60年代末在美國首先出現，當時叫可編程邏輯控制器PLC（Programmable Logic Controller），目的是用來取代繼電器，以執行邏輯判斷、計時、計數等順序控制功能。PLC的基本設計思想是把計算機功能完善、靈活、通用等優點和繼電器控制系統的簡單易懂、操作方便、價格便宜等優點結合起來，控制器的硬件是標準的、通用的。根據實際應用對象，將控制內容編成軟件寫入控制器的用戶程序存儲器內。控制器和被控對象連接方便。
隨著半導體技術，尤其是微處理器和微型計算機技術的發展，到70年代中期以后，PLC已廣泛地使用微處理器作為中央處理器，輸入輸出模塊和外圍電路也都采用了中、大規模甚至超大規模的集成電路，這時的PLC已不再是邏輯判斷功能，還同時具有數據處理、PID調節和數據通信功能。
可編程控制器是一種數字運算操作的電子系統，專為在工業環境下應用而設計。它采用了可編程序的存儲器，用來在其內部存儲執行邏輯運算，順序控制、定時、計算和算術運算等操作的指令，并通過數字式和模擬式的輸入輸出，控制各種類型的機械或生產過程。PLC是微機技術與傳統的繼電接觸控制技術相結合的產物，它克服了繼電接觸控制系統中機械觸點的接線復雜、可靠性低、功耗高、通用性和靈活性差的缺點，充分利用微處理器的優點。
可編程控制器對用戶來說，是一種無觸點設備，改變程序即可改變生產工藝，因此可在初步設計階段選用可編程控制器，在實施階段再確定工藝過程。另一方面，從制造生產可編程控制器的廠商角度看，在制造階段不需要根據用戶的訂貨要求專門設計控制器，適合批量生產。由于這些特點，可編程控制器問世以后很快受到工業控制界的歡迎，并得到迅速的發展。目前，可編程控制器已成為工廠自動化的強有力工具，得到了廣泛的應用。
