大家好！一般大家在寫(xiě)PLC程序時(shí)，控制伺服與氣缸的動(dòng)作中是怎樣記憶動(dòng)作流程的，比如非正常停機時(shí)或者報警復位后再次啟動(dòng)，程序會(huì )記憶上次沒(méi)有執行完的步驟接著(zhù)繼續動(dòng)作？有什么好思路，請指教一二，謝謝！
相信自我！

暫�；蚴肿詣�(dòng)切換時(shí)觸發(fā)一個(gè)上升沿，用這個(gè)上升沿把氣缸狀態(tài)、軸位置等保存在掉電保持繼電器，這個(gè)用來(lái)繼續控制時(shí)比較狀態(tài)。自動(dòng)流程用case of ，流程步驟數值也用斷電保持。麻煩的就是機構動(dòng)作多，手動(dòng)操作后還要能繼續，這種情況要考慮到機構
