b.當有通道故障時，保護輸出被閉鎖。只有故障排除并按故障復位鍵后，故障狀態(tài)輸出才會被撤消，與此同時解除對保護輸出的閉鎖。
c.經(jīng)有效性診斷后，輸入信號分別進行超限判斷。判斷項目為：1.是否超預報限，若超則左右分別經(jīng)2s延時后（或左右相/或0后延時2s）輸出預報信號；2.是否超保護限，若超限且無故障閉鎖，則左右分別經(jīng)2s延時后（或左右相/與0后延時2s）輸出保護信號。
d. PMC676RCSC-1在延時2s期間，若預報復限則延時復歸；在延時2s期間，若保護復限或有閉鎖，則延時復歸。
PMC676RCSC-1 總結(jié)S7 300PLC繼承了西門子S系列PLC體積小，組態(tài)靈活、功能強大的傳統(tǒng)設(shè)計特色，非常適合機組主保護對熱工裝置的準確性、可靠性、完備性的要求。用S7 300PLC構(gòu)成的保護系統(tǒng)，利用其可OB35中程序流程編程特性，加強了保護系統(tǒng)的故障診斷邏輯功能和保護邏輯功能，特別是其保護誤動率大大降低的特點，遠遠優(yōu)于原來捷克組件那種靠繼電器硬接線實現(xiàn)保護邏輯動作的模式。
