1794-PS131794-PS131794-PS13存储器主要有两种：一种是可读/写操作的随机存储器RAM，另一种是只读存储器ROM、PROM、EPROM和EEPROM。在PLC中，存储器主要用于存放系统程序、用户程序及工作数据。系统程序是由PLC的制造厂家编写的，和PLC的硬件组成有关，完成系统诊断、命令解释、功能子程序调用管理、逻辑运算、通信及各种参数设定等功能，提供PLC运行的平台。系统程序关系到PLC的性能，而且在PLC使用过程中不会变动，所以是由制造厂家直接固化在只读存储器ROM、PROM或EPROM中，用户不能访问和修改。用户程序是随PLC的控制对象而定的，由用户根据对象生产工艺的控制要求而编制的应用程序。为了便于读出、检查和修改，用户程序一般存于CMOS静态RAM中，用锂电池作为后备电源，以保证掉电时不会丢失信息。为了防止干扰对RAM中程序的***，当用户程序经过运行正常，不需要改变，可将其固化在只读存储器EPROM中。现在有许***LC直接采用EEPROM作为用户存储器。＆公司全称：厦门泰尼电气有限公司＆销售代表：小黄＆洽谈电话：0592-6809319＆手机：18950191386＆商务***：2917675397＆传真（FAX)：0592-6890859（请注明，01006收）＆公司地址：厦门市海沧区海沧街道滨湖一里7号＆公司网址：SQUAREDSY/MAXRTD/DIRECTINPUTMODULE8030-RIM-12780SQUAREDSY/MAXRTD/DIRECTINPUTMODULE8030-RIM-12780KITAGAWASTEELCNCLATHECHUCK682081SC165A8342JN06ALLENBRADLEYPOWERFLEX70ACDRIVE1HP20AE1P7A3AYNNN...YASKAWAABBE-CLIPSEBYPASSDRIVE3HP480VACH550-VCR-0STOBERSERVOMOTORES54/454956/1343776/000/000/010/1GEELEKTRORBLOWER3.10kW4HPSD-540/M98/23019277/480VSEWEURODRIVES77R37DT71D4MM03CMOTORGEARBOX460Y.5HPDUFF-NORTONROTARYUNIONPRODUCTSCARTRIDGEL992147715DUFF-NORTONROTARYUNIONPRODUCTSCARTRIDGER992147155PARTLOWCHARTRECORDERMRC-7800MRC-7000786000100001GEGENERALELECTRIC0.1%COORDINATIONBOARDCARD193X70DolanJennerSafeScanSS9ControlBox24VVDC@1AmpHEDLANDFLOWMETER8050601-1/4"NPT80506091053000PHUBCITY0220-6406638640:1RATIOSPEEDREDUCERROSEMOUNTPWA01984-2551-0001OUTPUTBYPASS2REVH/TGouldShawmutCurrentLimitingFuseA4BY40004000A4000RELIANCEELECTRICDRIVEINVERTER3.7KVA2HPGV30002V21GE5K284SC115SEVERDUTYELECTRICMOTOR25HP25HP230/AllenBradley1336PlusDrive1336s-brf30-aa-de-ha1AIRBLASTINC3T-18-7.5CENTRIFUGALBLOWERFANW/BALDOBOSTONGEARSPEEDREDUCERGEARBOXCATNORF431DP-10-BSSD546.0180.4.8.1.010.1010.0.00DRIVE5460180481SSDDrive548.2550.4.8.1.088.1010.0.44548255048108854BALDORA-CWASHDOWNDUTYDRIVEID15H403-WZELLWEGERUSTERCONTROLCONTROLLERSLIDA-SPSLIDASP75VREBUILTTOSHIBAB0104YLF2AM10HPEXPLOSIONPROOFMOTORMETTLERTOLEDOWEIGHTWEIGHINGSCALEHEADTERMINALDISPAGILENTHPCIRCUITBOARDCARDE2929-66502E2929-66511EALLENBRADLEYMOTORCONTROLCIRCUITBOARD151083151132HEDLANDH834X-030-HEH834X030HEFLOWMETER30GPM110LPMGOULDSHAWMUTAMP-TRAPCS-3DOUBLEBARRELFUSEA550X300LENZE12.3HP9.2KWELECTRICMOTORW/BRAKE380-480VVOLRelianceCardpackCurrentSummingCard0-49060-1HOPEIND15S/STOUCHSCREENOPERATORINTERFACEMONITORROMAN70KVA70KVARESISTANCEWELDINGTRANSFORMERF4467ROMANRESISTANCEWELDINGTRANSFORMERF44685B1ABW85KVAROMANRESISTANCEWELDINGTRANSFORMERF44685B1AAW440V4BALDORBRAKINGTRANSISTORRTA4-10RTA410REQ.10OHMREBALDORBRAKINGRESISTORRGA4810RGA-481010OHMRESISTOREFUELEKTRONIKBRAKINGRESISTOR725557158268BELASTUNGEACCONTACTORA***AC2A02AA2A465X547R01400A5000VNorthAmericanCenterGuideDetectorH3118-30-86/15MOLINSOUTPUTINTERFACECIRCUITBOARDCARDSA2751-092SMETTLERTOLEDOWEIGHTINDICATORDOTMATRIXSCALEPRINTEAIRMONITORVELTRONIIPRESSUREFLOWTRAN***ITTERFINCORESIDRIVE313510HP10HP460V104596001DATATRANSLATI***CIRCUITBOARDDT332REVTNIBONANCUMMINSPOWERCOMMANDDIGITALMODULEBOARDDIMKITALLENBRADLEYPCBBASECIRCUITDRIVEBOARD150HP150HPMURRAYELECTRICALENCLOSUREW/THERMALEDGEACaircondiCARRIERPROCESSORCIRCUITCONTROLBOARDCARDHK35EZ001RelianceElectricRectifier78178-1RR781781RRGEGENERALELECTRICINTERFACECARD193X528ADG02RAYCAMPCOS4TL112.2PSTAINLESSS/SBAGSOCKFILTERW/ABBSTROMBERGPOWERSUPPLYBOARDSAFT110POWSAFT110POWALLENBRADLEYROCKWELLAUTOMATIONCONTROLBOARD74101-1FLYNNDIVELBISSFLAMEPLA***AANALYZEROPERATORINTERFACITWRANSBURGLOWVOLTAGEMODULE9040CASCADEPAINTPOWEWHITESTORAGE&RETRIEVAL680MOTORCONTROLLERDRIVEE9BALDORVM7035T1.5HPMOTORFORHAZARDOUSLOCATI***)
