IC697ADC701控制器;IC697ADC701控制器;IC697ADC701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。ASEABROWNBOVERI57360001-K/9USPP57360001K9GOSSWH715214-HNSPPWH715214HFANUCA20B-0010-0130USPPA20B00100130TEXASINSTRUMENTSPLC505-4432USPP5054432ASEABROWNBOVERIACS601-0016-4-​000B1500801USPPACS60100164000​B2ALLENBRADLEY150-A54NBUSPP150A54NBOMRONC200H-MC221USPPC200HMC221SiemensTexasInstrumentsPLCController435-CPU405-15ABMU-55NUsedWorkingSAFTRONICSGP10E1ST32030B​1USPPGP10E1ST32030B​1ASEABROWNBOVERI3HAB8797-1/2BUSPP3HAB879712BASEABROWNBOVERISNAT-622-CMTUSPPSNAT622CMTORIENTALMOTORBLD180A-MKUSPPBLD180AMKPanasonicMDDDT5540001ACServoASEABROWNBOVERIDPH-15051NSFPDPH15051ASEABROWNBOVERIS4L250EWUSPPS4L250EWGRACEINTERNATIONALCORP421421-3NSFP4214213SiemensTI510-2102PLCALLENBRADLEY20AD8P0A3AYNNN​NNUSPP20AD8P0A3AYNNN​NNMEASUREX08596900USPP08596900TexasInstruments505-7002ASEABROWNBOVERI3HAC-17484-2/0​0NSPP3HAC17484200SIEMENS6SL3353-6TE411​CA3NSFP6SL33536TE411C​A3RELIANCEELECTRIC0-54339NSPP054339panasonicacservomotorMDM202A1CWithTsubakiNEWTEXASINSTRUMENTSPLC315-10SNSFP31510STEXASINSTRUMENTSPLC565-1101USPP5651101ASEABROWNBOVERIS6HQ800BWAS4NSPPS6HQ800BWAS4ASEABROWNBOVERI3AFE61004955NSFP3AFE61004955TEXASINSTRUMENTSPLC500-5828USPP5005828SimaticTI330DirectLogicPLCcompleteWithprogrammerACTUSPOWERNPSA-103MU-EIB​S/1680336BUSPPNPSA103MUEIBS1​68Returns:NotacceptedASEABROWNBOVERI57411546USPP57411546ASEABROWNBOVERIDSSR-115USPPDSSR115MEASUREX09429200USPP09429200ASEABROWNBOVERIPCU-03USPPPCU03REXROTH0-608-820-099USPP0608820099ONLINEDEVELOPMENTINC97282901NSPP97282901TEXASINSTRUMENTSPLC505-4016AUSPP5054016ATEXASINSTRUMENTSPLC949024-000-3USPP9490240003FUJIELECTRICB128C-2ANSFPB128C2ABYSTRONIC702109USPP702109WESTINGHOUSE772B388G55NSPP772B388G55PanasonicACServoMotorMAMR042R1A1NewinBoxFreeShipASEABROWNBOVERI57160001-TPUSPP57160001TPASEABROWNBOVERI57360001-EF/1USPP57360001EF1TEXASINSTRUMENTSSiemensTIPN560-2126RemoteComModTexasInstrumentSiemensthermocoupleinputmodule500-50513ailableTEXASINSTRUMENTSPLC575-4332NSFP5754332ASEABROWNBOVERI57088478NSFP57088478MITSUBISHIMDS-A-CR-55USPPMDSACR55ASEABROWNBOVERIDSSR-115USPPDSSR115530T-1112TexasInstrumentsTIPLCProcessor530T1112N6ALLENBRADLEY1336-151140NSPP1336151140TexasInstruments500SystemPLCSeriesRack13ModulesOPCON2300A-7502NSFP2300A7502TEXASINSTRUMENTSPLC500-2153NSFP5002153MODICONAS-E685-914USPPASE685914GENERALELECTRICDS3800DOAAUSPPDS3800DOAAASEABROWNBOVERIACS60100206000​B1200900USPPACS60100206000​B1TexasInstruments7MT100ALLENBRADLEY1336S-BRF50-AN​-EN4-HA2-L5NSFP1336SBRF50ANEN​41TexasInstrumentsRTU-T056A&520-058TEXASINSTRUMENTSPLC510-3103USPP5103103Panasonic2.0kWACServoMotor***202D1C(freeshipping)TexasInstrumentsiManVMEInterfaceII01-31073-104ABoard*60DAYSWARRANTY!*TexasInstrumentsPM550-400LoopAccessModulePM550400ASEABROWNBOVERID***C-110NSPPD***C110TexasInstruments505-6870Returns:NotacceptedTEXASINSTRUMENTSPLC505-4208ANSFP5054208AASEABROWNBOVERIDSQC116USPPDSQC116ALLENBRADLEY1770-FLUSPP1770FLNILFISKADVANCEGM-625USPPGM625ASEABROWNBOVERIDSDX-110NSPPDSDX110TexasInstruments500-5011PanasonicACServoDriverMSDA3A5A1TEXASINSTRUMENTSTI500-5038NETWORKINTERFACEMODULE)
