IC693PWR321R
采用狀態(tài)設計法編制控制程序梯形圖。狀態(tài)設計法就是根據(jù)具體對象的運動狀態(tài)分配中間變量作標記，然后針對各個狀態(tài)給予實際控制的設計方法。其關鍵是確定系統(tǒng)在工藝流程中的狀態(tài)及狀態(tài)轉化的條件，分析系統(tǒng)的狀態(tài)必須充分考慮各種情況。在本系統(tǒng)軟件設計中，首先按工藝流程對焊機各運行狀態(tài)（如擋板下降、導輥上升、小車前進、焊接開始等）分配中間變量；然后確定各狀態(tài)的先后次序及聯(lián)鎖關系；明確系統(tǒng)所要涉及到的輸入、輸出量，畫出PLC各輸出信號與輸入信號的邏輯關系；再由邏輯關系轉化為梯形圖。該程序分別由鋼帶定位、小車控制、過程監(jiān)控、故障診斷等控制程序組成，采用狀態(tài)設計法編制后，梯形圖程序流程有序、邏輯清晰。鋼帶焊接過程時間雖短，但條件多，動作復雜，為此，將系統(tǒng)的運行和故障聯(lián)鎖等全部由PLC控制，以提高系統(tǒng)的可靠性；在軟件設計中適當添加聯(lián)鎖條件，使各動作間嚴格確保相互約束或定時關系；建立合適的狀態(tài)標志位，如對焊機的“焊接完了”、“小車前后條件”、“故障停機”等建立標志位，并準確應用于各控制狀態(tài)的設計中；設置識別及處理故障的能力，對系統(tǒng)中的冷卻水、空壓及變頻器等異常采用延時確認方式。
