6DD1661-0AB0控制器6DD1661-0AB0控制器维控plc在恒压供暖系统的应用一、简介供暖系统主要用于北方冬季暖气系统供暖，控制两电机对供暖系统水压控制在恒定范围内，用plc控制减小了工作人员工作量，无需值班人员看守。二、特点1、使用维控的PLC，PLC型号为20MT。2、PLC程序内置算法，通过modbus通讯读取水压值以及变频器当前频率值，当水压不够使plc控制变频器让补水泵开始工作，一定时间内，启动1#补水泵变频启动，变频一定时间即变频达到50hz，水压仍然达不到值，1#补水泵切换到工频，2#变频启动，直到水压保持在设定值内，当水压恒定在设定值内，即1#工频2#变频运行，此时如果变频器频率低于设定的频率运行超过设定时间，将自动切换到1#变频启动状态。2#电机停止运行。3、系统中还包含无水信号、变频器故障报警信号。水箱中无水信号、变频器故障报警信号送达plc，系统停止工作。三、组成部分1、PLC负责动作的直接控制和外界反馈的信息的采集，实现供水系统的自动运作和故障检测。PanasonicM***A012C1EACServoMotorFreeShipDEZURIKP2000USPPP2000TISiemensCTi500-50195005019WordOutputPLCALLENBRADLEY813S-VOAUSPP813SVOAFANUCA20B-1001-0551USPPA20B10010551PanasonicACServoDriverMSD083A1XXFreeShipMATTEC561-1008AUSPP5611008APANASONICACSERVOMOTORMFA024LA2NSJNEWPANASONICSERVODRIVERMfDDTA390L013KWASEABROWNBOVERIYT212003-UBUSPPYT212003UBGEFANUC44A398714-G01USPP44A398714G01ASEABROWNBOVERI3BSE004939R1NSPP3BSE004939R1TEXASINSTRUMENTSPLC140-1114NSFP1401114ALLENBRADLEY150-A35NB-ND-8​L4AUSPP150A35NBND8L4AASEABROWNBOVERIDSCS-116USPPDSCS116PanasonicACServoMotorM***011A1EFreeShipFujiHensokukiCOGeardMotorMT-9-5.4-002LAPanasonicACServoMotorMQMA022P2BTEXASINSTRUMENTSPLC575-2102USPP5752102PanasonicMinasMSD023A1X05ACServoDriverFreeShipTEXASINSTRUMENTSPLC545-1106USPP5451106ALLENBRADLEY2705-EM11J1396​35USPP2705EM11J13963​5ASEABROWNBOVERIAPIOS-02USPPAPIOS02ALLENBRADLEY1771-OF05NSFP1771OF05ASEABROWNBOVERIACS800-U1-0011​-5USPPACS800U100115ASEABROWNBOVERIDSFS-11USPPDSFS11TEXASINSTRUMENTSPLC500-5012NSPP5005012STEBONSDT-853-500-54​-N1623NSFPSDT85350054N16​23TEXASINSTRUMENTS500-5018WORDINPUTMODULENEW5005018ALLENBRADLEY160-BA04SF1-AF​-D13-DN2C-DNRC​-DNSC1-DSUSPP160BA04SF1AFD1​3DTEXASINSTRUMENTSPLC949025-000USPP949025000PanasonicServoDrive&MotorSetMQDA023A1AnewPanasonicMFA075LD5NSJACServoMotor750WTEXASINSTRUMENTSPLC530C-1108USPP530C1108TexasInstrument500-588412ModuleI/Obase5005884A+ASEABROWNBOVERI3HAA2207-002USPP3HAA2207002PANASONICSERVODRIVER/ADKA100​BPTADZ/AMKA080​810KAE/NEWNEWSEALTISiemens575-21045752104VMEPLCCPUSQUAREDATV-58NU90N4KUUSPPATV58NU90N4KUASEABROWNBOVERIEHN550C-1NSFPEHN550C1ALLENBRADLEY284D-FHD6P0D-2​5-CR-3NSFP284DFHD6P0D25C​R3PERCEPTRONTRICAMCONTOURSENSOR9163073ASEABROWNBOVERI57340001-K/1USPP57340001K1PanasonicMHDA153A1AACServoDrive1.5kW(freeshipping)ANNARBORINX7P133-TFTTUSPPINX7P133TFTTGENERALELECTRICDS3800HIOA1B1BUSPPDS3800HIOA1B1BASEABROWNBOVERIACS601-0009-4-​000B1200801USPPACS60100094000​B1TexasInstruments500-5001ASEABROWNBOVERI750191-001BNSFP750191001BASEABROWNBOVERI3HAA3563-AHA/1USPP3HAA3563AHA1ASEABROWNBOVERIEH175C-1NSFPEH175C1TexasInstrument560-2127BTexasInstrumentsProgramableControlerPLCM#305-02BTEXASINSTRUMENTSPLC305-CPU-RTUUSPP305CPURTUASEABROWNBOVERIYB560103-ANUSPPYB560103ANReturns:NotacceptedCTICRYOGENICS8112105NSPP8112105TEXASINSTRUMENTS500-50235005023ALLENBRADLEY1398-HMI-003USPP1398HMI003TEXASINSTRUMENTSPLC7MT-600NSFP7MT600TEXASINSTRUMENTS520C-1102SERIES500CONTROLLERREV2.6520C11026TexasInstrumentsI/OModules,DifferentTypes!INDRAMATDKC04.3-100-7-​FWUSPPDKC0431007FWASEABROWNBOVERIYT213001-AAUSPPYT213001AAPanasonicACServoMotorM***A082A1ENewInBoxFreeShipPanasonicACSERVOMOTORMUMS022A1E0S200WFreeShipYASKAWAELECTRICJANCD-HA03NSPPJANCDHA03(5)TexasInstruments6MT50-1I/OMountingBaseNEW*BASLERELECTRICBE1-25/79TRNSFPBE12579TRTexasInstrumentsPM550-210TEXASINSTRUMENTS500-5011OUTPUTMODULELOT5005011TexasInstruments(Siemens)Mdl:500-5039I/FModuleTEXASINSTRUMENTSPLC0941370-8200USPP09413708200)
