詳細(xì)內(nèi)容：大量的工程實(shí)踐表明，PLC外部輸入、輸出設(shè)備的故障率遠(yuǎn)遠(yuǎn)高于PLC本身的故障率，而這些設(shè)備出現(xiàn)故障后，PLC一般不能覺(jué)察出來(lái)，可能使故障擴(kuò)大，直至強(qiáng)電保護(hù)裝置動(dòng)作后才停機(jī)，有時(shí)甚至?xí)�造成設(shè)備和人身事故。停機(jī)后，查找故障也要花費(fèi)很多時(shí)間。為了及時(shí)發(fā)現(xiàn)故障，在沒(méi)有釀成事故之前使PLC自動(dòng)停機(jī)和報(bào)警，也為了方便查找故障，提高維修效率，可用PLC程序?qū)崿F(xiàn)故障的自診斷和自處理。 　　現(xiàn)代的PLC擁有大量的軟件資源，如FX2N系列PLC有幾千點(diǎn)輔助繼電器、幾百點(diǎn)定時(shí)器和計(jì)數(shù)器，有相當(dāng)大的裕量，可以把這些資源利用起來(lái)，用于故障檢測(cè)。 聯(lián)系人：黃曉飛(銷售工程師) 移動(dòng)電話:18030263579 固話:0592-6895320 QQ：2472574325 全球瘋狂低價(jià)甩賣 NEW GREAT LAKES BELTING QPH110WFBB FRICTION BRUSH BELT NIB ALLEN BRADLEY 700-HHF62Z12 FLANGE MOUNT POWER RELAY 1991 GEO PRIZM ELECTRICAL DIAGNOSIS SERVICE MANUAL ALLEN BRADLEY 700DC-F400 CONTACTOR 1998 P12 CHASSIS MOTORHOME SERVICE MANUAL VOL 1-3 1999 GEO METRO M-PLATFORM SERVICE MANAUL LOT OF 2 NIB NORTON 1601BFH TRI STYLE DOOR CLOSER 696 TROEMNER 8416T CALIBRATION WEIGHT SS ELECTRONIC BALANCE NIB TRICO 30052 OPTO-MATIC OILER PNEUMATICS NIB SQUARE D QOUR220 CIRCUIT BREAKER 20 AMP 2 POLE* SICK LUT1-440 OPTIC ELECTRONIC LUMIN SENSOR WITH LENS 1994 CHEVY LUMINA SILHOUETTE TRANS SPORT SERVICE MAN -2 CONTINENTAL SAFETY EQUIP CALIBRATION KIT NIB HORTON NEXEN 940001 PRESSURE REGULATOR NEW ASCO RED HAT 8223A21 SOLENOID VALVE 1/4 2NC* NIB SIEMENS 5SX2 220-5 CIRCUIT BREAKER 2 POLE 20 AMP* NIB SIEMENS 5SX2 225-5 CIRCUIT BREAKER 2 POLE 25A CONTINENTAL SAFETY EQUIP CALIBRATION KIT CONTINENTAL SAFETY EQUIP CALIBRATION KIT CONTINENTAL SAFETY EQUIP CALIBRATION KIT NIB ROPLAN 110-50 MOG 3000 RETAINER NIB ROPLAN 110-11 MOG 3000 STAT.SIC NEW PANDUIT PLT8EH-Q0 CABLE TIES WEATHER RESISTANT 25 NIB FURNAS 69GA6 PRESSURE SWITCH 2 POLE NIB TELEMECANIQUE XSD A600519H7 INDUCT PROXIMITY SWITCH NIB VICTOR MEDALIST TPR250-125-580-0781-9133 REGULATOR NIB ALLEN BRADLEY 700-HG47A4 CONTROL RELAY NIB ARROW F329-08 LP PARTICULATE FILTER 300 SCFM NIB PREST0-O-LITE ESAB R-36-400-580 INERT REGULATOR NEW GOULD ITE G203F RENEWAL CONTACTS KIT SIZE 4 3 POLES NIB SIEMENS 5SJ4 306-8HG41 CIRCUIT BREAKER 6AMP 3 POLE NEW GOULD ITE G203G RENEWAL CONTACTS KIT SIZE 5 NIP SIEMENS 8US1923-2AA01 BUSBAR HOLDER 600MM EX FIX* NEW SIEMENS 51PC5G3LB PILOT LIGHT TRANSFORMER 120 VOLTS NEW BRYANT BRD BR20-30 2 POLE TANDEM CIRCUIT BEAKER ZINSCO CN-54 MAGNETRIP CIRCUIT BREAKER 1 POLE 20 AMP NEW GE 24PSB MINIATURE INCANDESCENT LIGHT BULB 2W 24V 1999 CHEVY EXPRESS GMC SAVANA SERVICE MANUAL LOT VOL1-3 NEW GE PR2 SINGLE CONTACT LIGHT BULB 1 WATT 2.38 V* NEW THOMAS BETTS MOUNTING BASE PANEL MOUNT NIB SIEMENS MMSKF3 MANUAL SWITCH 2 POLE TOGGLE* NIB ACUITY CM4000 B/W CCD MINIATURE CAMERA 1992 PONTIAC GRAND AM SERVICE MANUALS LOT OF 2 NEW GE 85 MINIATURE LAMPLIGHT BULB 28V 0.04A* GTE SYLVANIA CIRCUIT BREAKER 2 POLE TANDEM BREAKER 30A 1998 CHEVY ASTRO GMC SAFARI SERVICE MANUAL VOL1-3 NEW GE 120PSB MINIATURE INCANDESCENT LIGHT BULB* 1998 CHEVY TRACKER SERVICE MANUAL VOLUME 1-3 ZINSCO TYPE Q 20 AMP 1 POLE CIRCUIT BREAKER 1999 CHEVY PRIZM SERVICE MANUAL VOLUME 1-2 1993 PONTIAC GRAND AM SERVICE MANUAL VOLUMES 1-2 1998 CHEVY GMC M/L VAN SERVICE MANUALS VOLUMES 1-3 NIP PANDUIT CFPE2WH MINI COM FACEPLATE LOT OF 2 WOMENS VINTAGE HALLOWEEN COSTUME DRESS SIZE SMALL MED WOMENS VINTAGE FEINER FASHIONS ROBE PAJAMAS SIZE L XL A16B-2200-020配件 A16B-2200-020配件 A16B-2200-020配件 WOMENS VINTAGE JC PENNEY GAYMADE ROBE PAJAMAS SZ L XL
