1783-MS06T1783-MS06T1783-MS06TOPC客户和OPC服务器进行数据交互有2种访问方式：同步和异步方式。同步方式实现较为简单，客户向服务器发出读写请求，然后等待服务器返回信息，当***较少而且同服务器交互的数据量比较少的时候可以采用这种方式，然而当网络堵塞或大量客户访问时，会造成系统的性能效率下降。异步方式实现较为复杂，客户向服务器发出读写请求后，服务器立刻返回信息表示请求已接受，客户可以进行其他处理，当服务器完成读写操作后，通过调用回调函数，通知客户程序操作完成，并传递相应的信息，因此异步方式的效率更高，能够避免多客户大数据请求的阻塞，并可以***大限度地节省CPU和网络资源。另外一种异步方式是服务器周期性的扫描缓冲区的数据，发现数据变化范围超过死区后，立刻通知客户程序，传递相应信息。【***】【诚信】【创新】【合作】【共赢】厦门泰尼电气有限公司【产品质量】原装进口***【检测标准】按原厂标准【产品质保】1年【快递时间】24小时到【联系我们】＆业务经理：小黄＆洽谈电话：0592-6809319/18950191386＆商务***：2917675397＆传真（FAX)：0592-6890859（请注明，01006收）＆公司全称：厦门泰尼电气有限公司＆公司地址：厦门市海沧区海沧街道滨湖一里1号楼CutlerHammerCH***UnitrolAdvantageSize4MCCBCUTLERHAMMERD520BC33NSPPD520BC33CUTLERHAMMERJD3070NSFPJD3070CUTLERHAMMERECN2221AAFNSFPECN2221AAFCUTLERHAMMERECN2218AJDNSPPECN2218AJDS701C25B3SCutler-HammerMiniSoftStarterwithbrakeCUTLERHAMMERGRT-1NSFPGRT1Cutler-HammerPanelmatePowerPro1755KTouchPanelEaton/CutlerHammer7585DT-15OperatorInterface15.1"CUTLER-HAMMERDRYTYPEDISTRIBUTIONTRANSFORMER75KVA75KVACUTLER-HAMMERDRYTYPEDISTRIBUTIONTRANSFORMERCUTLERHAMMER92-01670-00USPP920167000NEWCUTLERHAMMERSV9F30AC-5M0B00DRIVESV9F30AC5M0B00cutlerhammermotorstartersize6cn15tn3coil120v##NEWCUTLERHAMMERDH363UWKSTAINLESSSAFETYSWITCH100ACutlerHammerDH366FRK600amp3RFuseddisconnectCutlerHammerCircuitBreakerHFD315OL150AMP(2990)NEWCutlerHammer9-758-20480vCoilNEWClipperPowerSystemSurgeProtectorcutler-hammerCUTLERHAMMERSV9030AS-5MOAOOACDRIVECutlerHammerCircuitBreaker250AMPHJD3250F___XX22CutlerHammerHMDL3800F3pole800ampTripBreakerCUTLERHAMMERSTACKMETERBASEDISCONECT600AMPBOXCUTLERHAMMERD500-CPU25AUSPPD500CPU25ACUTLERHAMMER1575KHX/92-01804PANELMATE1500CUTLERHAMMERACCURRENTRELAYD60LA4~NewinboxCutler-HammerAN16NN0A-NewStyle,NewinBox!Cutler-HammerAN16NN0B-NewStyle,NewinBox!Cutler-HammerAN16NN0C-NewStyle,NewinBox!CutlerHammerHJD3250Fcircuitbreaker200ashunttripCUTLERHAMMERHMCP400X5WM01S10Y07NSPPHMCP400X5WM01S10CutlerHammerdrytypeTransformer75kva480-480Y/277NEWCPS100480DSCCutlerHammerSurgeSuppressorCutlerHammerWH400AAmpBusBreakerSwitchIBPIBPKDCUTLERHAMMERECN1811AJCNSFPECN1811AJCCUTLERHAMMERDH322NWKUSPPDH322NWKCutler-HammerA200M3CACNon-ReversingStarterJNEWEATONCUTLER-HAMMERHFD3200LSERIESCCIRCUITBREAKERCUTLERHAMMERNon-AutoSwitchLDB3600KLDB-K600ALDBCUTLERHAMMER92-00684-02USPP920068402Cutler-HammerMC3800FCUTLERHAMMERKDB3350350A/600VACCIRCUITBREAKERCUTLERHAMMER98-00100-00USPP980010000CutlerHammerCH400APanelboardSwitchEESWR360400TB2CUTLERHAMMERD800VCP1218USPPD800VCP1218CUTLERHAMMERKD2400FUSPPKD2400FCUTLERHAMMERHMCP400X5CNEWHMCP600V400AMP3POLEIPTB-400Cutler-HammerBuswayAN16NNOACHCutlerHammerAN16NN0ACutler-HammerHighVoltageFuse15CLE-300E/15CLE300ECUTLERHAMMER7585DT12USPP7585DT12CUTLERHAMMERECN1614AAAUSPPECN1614AAA9616NEWCUTLERHAMMER9616FREESHIPPING96113NEWCUTLERHAMMER96113FREESHIPPING9611NEWCUTLERHAMMER9611FREESHIPPING5HP460VEaton/CutlerHammerVFD-NewCutler-HammerLB3150Cutler-HammerLB3300CUTLERHAMMER42-10215-03USPP421021503CUTLERHAMMERFW3200JLNSFPFW3200JLCUTLERHAMMERD520FT16NSFPD520FT16Eaton/CutlerHammer112.5kVADryTransformerKT-13K-factorsuitablefornon-sinusoidalcurrentload100CUTLERHAMMERCIRCUITBREAKER-BR2100,2P,100AMPCutlerHammerClipperSuppressor,CPS160208YAA,NEWLGH3630NNCutlerHammerbreakerCUTLERHAMMER112.5KVATRANSFORMER480DLT208Y120LVCIRCUITBREAKERCUTLERHAMMER600AMPSL630EHFDEEaton/Cutler-HammerCircuitBreakerHFDE322536CutlerHammer200AmpATC-200TransferSwitch*USED*Cutler-HammerHMCP400X5CCutler-HammerIndustrialBreaker600Amp3poleL630ECutler-HammerIndustrialBreaker600Amp3poleL630CUTLERHAMMERSV9F30AJ5M0A00USPPSV9F30AJ5M0A00CUTLERHAMMER92-00240-00USPP920024000electricsupplylotcutlerhammerandmoreCUTLERHAMMERHFDE3160336606C22G05CIRCUITBREAKERCutler-HammerC10JN3Size6contactorseriesCCI540ampCutlerHammerSize2StarterM#ECN2228AAF84-28757-9)
