1756-OA8D/ABPLC模塊

由于PLC容易與工業控制系統連成一個整體，易于擴展功能，具有接口簡單快捷、工作量小、適合于較為惡劣的運行環境、故障率低、可靠性好、抗電氣*力強，維護方便等優點。

3.4  PLC采用掃描式的工作方式，特別適合于邏輯控制要求較高的順序控制。

3.5  我廠的順序控制系統流程較為復雜，90年代前期所用常規的繼電器硬線控制方式規模龐大、維護困難、故障和事故發生機率較高，出現故障后不利于查找并消除故障，設備隱患較多，在我廠采用傳統方式的繼電器順序控制方式，其安全生產記錄常常打破，我廠采用PLC控制后，不僅提高了設備可靠性，而且對設備的檢修維護都十分方便快捷，無需將機組及附屬設備退出運行即可解決，大大提高了工作效率，而安全生產記錄已接近3000天，創歷史高記錄。
