1794-OA81794-OA81794-OA83.CPU模块中的存储器存储器分为系统程序存储器和用户程序存储器，系统程序相当于个人计算机中的操作系统，它使PLC具有基本的智能，能完成PLC设计者的规定的各种工作。系统程序由PLC的生厂家设计并固定化在ROM（只读存储器）中，用户不能读取。用户程序由用户设计，它使PLC能完成用户要球的特定功能，用户程序存储器的容量以字节（B）为单位。（1）.随机存取存储器（RAM）用户可以用编程装置读出RAM中的内容，也可以将用户程序写入RAM，因此RAM又叫读/写存储器。RAM的工作速度高、价格便宜、改写方便。（2）.只读存储器（ROM）ROM的内容只能读出，不能写入。（3）.可以电檫出可编程的只读存储器（EEPROM）S7-200用EEPROM来存储用户程序和长期保存的重要数据。备货，备货，降降降，火火火，火火火……————————————————————————————————公司名称：厦门泰尼电气有限公司联系人：小黄（销售代表）联系电话：0592-6809319传真号码：0592-6890859（麻烦备注01006收）手机：18950191386***号码:2917675397邮箱：2917675397@***.com诚信经营，质量为首，诚信至上，泰尼电气小黄竭诚为您服务！！！————————————————————————————————BALDORDIGITALSOFTSTARTDRIVE146A146AMPMD8-146-CBREXROTHINDRAMATSERVODRIVE37A40A40AMPHDS03.2-W07NETZSCHSCREWPUMPXLBJVMJV178-450MOTORSHAKERVIBRATECHVIBRATORYSIEMENSSIMATICBOXPCCOMPUTER627B6ES7647-6BD26-2BF0REXROTHINDRAMATSERVODRIVE60A120AHDS04.2-W200NHDSSquareDEnclosedCircuitBreakerNAL36900900A600VGIDDINGS&LEWISPIC900TURBOCPUMODULE502-03814-60R1MAZATROLCAMM-2CONTROLINTERFACESTATIONCOMPLETE55GALLUBRIPLATEFISKEFOODGRADELUBRICANTFMO-85APGGORMANRUPPMOTOPUMPRGS3D4R-B15HP15HP230/460V3PHABBTAYLORVIDEOMODULE6011BZ10001B-2589MC-5217CABBTAYLORVIDEOMODULE6011BZ10001B-2558MC-5217CALLENBRADLEY2705-T14J3LIGHTEDPUSHBUTTONMODULE90-REBUILTSTAHLKONTORGFQ132-240KW54HPDCMOTOR440VVSquareDSymaxModel500Processor8020SCP-523XSCP523GARDNERDENVER74043AA9C3SERIESAIRROTARYMOTOR400RELIANCERECTIFIERSTACK86466-12R8646612R86466SIEMENSSIMATICS7-300CPUMODULE6ES7318-2AJ00-0ASUS***ANES6060KW60KWELECTRICBOILER3PHASE480V48WARNERELECTRICSECOACFLUXDRIVESV3000SV341A-23000GECircuitBreakerTPVF56161600A1600AAmp600VAC3PMETROLOGICHOLOTRAKHOLOTRAKBARCODEBARCODESCANNERSQUAREDPBQ4640GSER6400A400AAMPFUSIBLEBUSWAYSYASKAWAYRFL-NNA10GDMOTOMANROBOTROBOTICARM10KG22LModiconAEG410ServoPositioner410-3/S908110-283110CONTROLTECHNIQUESEMERSONMODULARDRIVEPOWERSUPPLYMAllenBradleyServoMotorMPL-A310P-MJ22AAA0.98HP3PZUMBACHLASERMEASURINGHEADCONTROLATCONTROLLERODACACRAMATICCINCINNATINCPCIRCUITBOARDCARD3-533-0763GGE9T23Y3877225KVA225KVATRANSFORMERHIVOLT480VLOCARVER3X2.5X10CENTRIFUGALPUMP300GPM75FOOTHEADW/GESPECTRA400A400AAMPPANELBOARDBREAKERPANEL480DANFOSSVLT5000VLT5000ACDRIVEVLT-5042VLT5042ABBASEABROWNTAYLORUPSMODULE6221NP10100A-832ALLENBRADLEY1326AB-B7400-21155349ACSERVOMOTORALLENBRADLEYPANELVIEWPLUS1000OPERATORINTERFACE27YALEKEL22TON4000LBCHAINHOISTW/POWERTROLLEY230/EUROTHERMSCRCONTROLLERCONTROLDRIVE75A75AMPTU1471SQUAREDSIZE6SZ6MOTORSTARTER8536SHO2S4SHO2SHFEDERALPACIFICMODEL36B112.5KVA3PHTRANSFORMERHI4CUTLERHAMMERV48M28T22L225KVA225KVATRANSFORMERHISOLASOLATRONACUVOLTAC13T1539-59-315VOLTAGEREGULATAllenBradley15KWACServoControllerAxisModule139REXROTHINDRAMATSERVODRIVE37A37AMPAHDS02.2-W040N...COTTERMANMAXI-LIFT176-BHELECTRIC17.5'FOOTPLATFORM)
