PLC硬件故障PLC的硬件故障較為直觀地就能發現，維修的基本方法就是更換模塊。根據故障指示燈和故障現象判斷故障模塊是檢修的關鍵，盲目的更換會帶來不必要的損失。1）電源模塊故障中國1FK2204-5AF00-1SA0 邏輯引擎一個工作正常的電源模塊，其上面的工作指示燈如“AC”、“24VDC”、“5VDC”、“BATT”等應該是綠色長亮的，哪一個燈的顏色發生了變化或閃爍或熄滅就表示那一部分的電源有問題。“AC”燈表示PLC的交流總電源，“AC”燈不亮時多半無工作電源，整個PLC停止。這時就應該檢查電源保險絲是否熔斷，更換熔絲是應用同規格同型號的保險絲，無同型號的進口熔絲時要用電流相同的快速熔絲代替。如重復燒保險絲說明電路板短路或損壞，更換整個電源。“5VDC”、“24VDC”燈熄滅表示無相應的直流電源輸出，當電源偏差超出正常值5%時指示燈閃爍，此時雖然PLC仍能工作，但應引起重視，必要時停機檢修。“BATT”變色燈是後備電源指示燈，綠色正常，黃色電量低，紅色故障。黃燈亮時就應該更換後備電池，手冊規定兩到三年更換鋰電池一次，當紅燈亮時表示後備電源係統故障，也需要更換整個模塊。2）I/O模塊故障輸入模塊一般由光電耦合電路組成；輸出模塊根據型號不同有繼電輸出、晶體管輸出、光電輸出等。每一點輸入輸出都有相應的發光二極管指示。有輸入信號但該點不亮或確定有輸出但輸出燈不亮時就應該懷疑I/O模塊有故障。輸入和輸出模塊有6到24個點，如果只是因為一個點的損壞就更換整個模塊在經濟上不合算。通常的做法是找備用點替代，然後在程序中更改相應的地址。但要注意，程序較大是查找具體地址有困難。特別強調的是，無論是更換輸入模塊還是更換輸出模塊，都要在PLC斷電的情況下進行，S5帶電插拔模塊是***不允許的。3）CPU模塊故障中國1FK2204-5AF00-1SA0 邏輯引擎通用型S5PLC的CPU模塊上往往包括有通信接口、EPROM插槽、運行開關等，故障的隱蔽性更大，因為更換CPU模塊的費用很大，所以對它的故障分析、判斷要尤為仔細。檢修實例：一臺PLC合上電源時無法將開關撥到RUN狀態，錯誤指示燈先閃爍後常亮，斷電復位後故障依舊，更換CPU模塊後運行正常。在進行芯片級維修時更換了CPU但故障燈仍然不停閃爍，至到更換了通信借口板後功能才恢復正常。6ES7408-1TA00-7AA06ES7408-1TA01-0XA06ES7408-1TB00-0XA06ES7408-1TX00-6XA06ES7408-1XX00-6XA06ES7412-1XF01-0AB06ES7412-1XF02-0AB06ES7412-1XF03-0AB06ES7412-1XF04-0AB06ES7412-1XJ05-0AB06ES7412-2XG00-0AB06ES7412-2XG04-0AB06ES7412-2XJ05-0AB06ES7412-3HJ14-0AB06ES7413-1XG01-0AB06ES7413-1XG02-0AB06ES7413-2XG01-0AB06ES7413-2XG02-0AB06ES7414-1XG01-0AB06ES7414-1XG02-0AB06ES7414-2XG01-0AB06ES7414-2XG02-0AB06ES7414-2XG03-0AB06ES7414-2XG04-0AB06ES7414-2XJ00-0AB06ES7414-2XJ01-0AB06ES7414-2XK05-0AB06ES7414-3EM05-0AB06ES7414-3XJ00-0AB06ES7414-3XJ04-0AB06ES7414-3XM05-0AB06ES7414-4HJ00-0AB06ES7414-4HJ04-0AB06ES7414-4HM14-0AB06ES7416-1XJ01-0AB0CI801 3BSE022366R1CI801kit 3BSE038540R1300CI810B 3BSE020520R1CI820V1 3BSE025255R1CI830 3BSE013252R1CI830kit 3BSE031695R1400CI840A 3BSE041882R1CI840kit 3BSE031694R4000TU846 3BSE022460R1TU847 3BSE022462R1TK212A 3BSC630197R1FS801K01 3BSE038407R1AI810 3BSE008516R1AI815 3BSE052604R1AI820 3BSE008544R1AI825 3BSE036456R1AI830A 3BSE040662R1AI835A 3BSE051306R1AI843 3BSE028925R1AI845 3BSE023675R1AI890 3BSC690071R1AI893 3BSC690141R1AI895 3BSC690086R1AO810V2 3BSE038415R1AO815 3BSE052605R1AO820 3BSE008546R1AO845A 3BSE045584R1AO890 3BSC690072R1AO895 3BSC690087R1DI810 3BSE008508R1DI811 3BSE008552R1DI814 3BUR001454R1DI820 3BSE008512R1DI821 3BSE008550R2DI825 3BSE036373R1DI830 3BSE013210R1DI831 3BSE013212R1DI840 3BSE020836R1DI885 3BSE013088R1DI890 3BSC690073R1DO810 3BSE008510R1DO814 3BUR001455R1DO815 3BSE013258R1DO820 3BSE008514R1DO821 3BSE013250R1DO840 3BSE020838R1DO890 3BSC690074R1DP820 3BSE013228R1DP840 3BSE028926R1TU805K01 3BSE035990R1TU810V1 3BSE013230R1TU811V1 3BSE013231R1TU812V1 3BSE013232R1TU813 3BSE036714R1TU814V1 3BSE013233R1TU830V1 3BSE013234R1TU831V1 3BSE013235R1TU833 3BSE038726R1TU835V1 3BSE013236R1TU836V1 3BSE013237R1TU837V1 3BSE013238R1TU838 3BSE008572R1TU839 3BSE046966R1TU842 3BSE020850R1TU843 3BSE021443R1TU844 3BSE021445R1TU845 3BSE021447R1TU850 3BSE050930R1TU890 3BSC690075R1TU891Z 3BSC840220R1TY801K01 3BSE023607R1TY804K01 3BSE033670R1AI801 3BSE020512R1AO801 3BSE020514R1DI801 3BSE020508R1中國1FK2204-5AF00-1SA0 邏輯引擎
