1756-OB321756-OB321756-OB32PLC的CPU与通用微机的CPU一样，是PLC的核心部分，它按PLC中系统程序赋予的功能，接收并存储从编程器键入的用户程序和数据；用扫描方式查询现场输入装置的各种信号状态或数据，并存入输入过程状态寄存器或数据寄存器中；诊断电源及PLC内部电路工作状态和编程过程中的语法错误等；在PLC进入运行状态后，从存储器逐条读取用户程序，经过命令解释后，按指令规定的任务产生相应的控制信号，去启闭有关的控制电路；分时、分渠道地去执行数据的存取、传送、组合、比较和变换等动作，完成用户程序中规定的逻辑运算或算术运算等任务；根据运算结果，更新有关标志位的状态和输出状态寄存器的内容，再由输出状态寄存器的位状态或数据寄存器的有关内容实现输出控制、制表打印、数据通信等功能。以上这些都是在CPU的控制下完成的。PLC常用的CPU主要采用通用微处理器、单片机或双极型位片式微处理器。※推荐品牌：※推荐公司Allen-Bradley厦门泰尼电气有限公司Schneider联系人：小黄（销售代表）Triconex固定电话：0592-6809319FOXBORO***:2917675397ABB邮箱：2917675397@***.comSIEMENS传真：0592-6890859MOTOROLA网址：www.xmtaini.comXYCOM地址：厦门海沧街道滨湖一里7号RexrothIndramat邮编：361026手机：18950191386ABB57298821ULMAKB2/AKEYBOARKEYPADWITHKEYALLENBBURKERTTHERMOSWITCH8400444698BNIBPT100-40/125CLOTOF2DOUBLEECORECHUCKAIRINFLATED5085888099MSADISPLAY490892SN02669TELEMOTIVEOUTPUTMODULEE7203-5E72035E7203-5TELEMOTIVEE-7203-1E72031E7203-1PCBBOARDMURATAMURATECMVL-RLY-151CN8-G1023-510MVR-R44-15ROSEMOUNT8711RRE30FR1MAGNETICFLOWTUBEMETER285PSI1ALLENBRADLEY1770-KF2DATAHIGHWAYCOMMUNICATIONINTERROSEMOUNT3311CURRENTTOPRESSURETRANSDUCER3311DS1J1VICKERSHYDRAULICDIRECTIONALVALVEDG5S4DG5S4048CEATONDURANTCOUNTER5881-158811-400118906INBOXROSEMOUNT01151-0934-00031151***ARTTRAN***ITTERELECTRROSEMOUNT2090PG2A22B1M5DIFFERENTIALPRESSURETRAN***ITROSEMOUNTPRESSURETRAN***ITTER1135F1S1B1E51135F1S1B1FANUCBOARDA16B-1210-0030/06FA16B1210003006FPINN***EULTRATOUCHUL-101-2PPALMBUTTONNIBALTEKMODEL235PROCESSVOLTAGEANALYZERADVANCEDMOTIONCONTROLSPWMAMPLIFIER30A8iTNIBJ***ELINELECTRONICSCOMPARATORJV3400RODIXFEEDERCUBEFC-93HPLUS121-8510121-000-8510NSKLINEARGUIDEBEARINGLHLH250LH250460GLC2W01P43WATLOWPROCESSCONTROLSERIES942942A-1BA1-A000PTICONTROLS118166REVK50027RV.01EXCELLONTHKLMSYSTEMHSR-25HSR25A1SSGK(LOTOF2)MURATAMURATECMVL-STD-MBD-102CN8-G1005-520MAGPOWR3D103-RPLPOWERCONTROLBOARD3D103RPLNIBOMRONV700-HMD13ARFIDR/WHEADV700HMD13ANIBWILDENDIAPHRAGMPUMPP.025/SLLL/BN/TF/SBN00-9753ROSEMOUNTCURRENTTOPRESSURETRANSDUCER33113311DS1J1FESTOVALVEMANIFOLDCPV14-GE-ASI-4E4A-ZM8170539GLIMODEL53FLOWMONITORE53A2A1NKAYDONREALI-SLIMBALLBEARING15163001OL79"ID11"OALLENBRADLEYETHERNETTCP/IPINTERFACE1756-ENET/BE01GENERALELECTRIC4006L5036G001PCBOARDROSEMOUNTTEMPERATURETRAN***ITTERE94-Q30SPR-2392D891GEFANUCLOCALI/OIC600BF900KIC600BF900METSOPOWERSUPPLYMODULEPEFT405402ALLENBRADLEYENCODER845H-SJHZ24CRY2SERBASHCROFTPSERIESTEMPERATURECONTROLSWITCHPTAN4H20A7ASHCROFTPSERIESTEMPERATURECONTROLSWITCHPPAN4HB25FOXBOROBS805JUFLOWCHAMBERFUJIBOARDFH1047C047C0970171EXCELLONETILTCP/FASSEMBLYMAG/AIRP-0888218177PTICONTROLSCIRCUITBOARDALLEN-BRADLEY5002750027005GEFANUCIC600-BF949L28KASCIIINPUTOUTPUTBOARDI/OEXCELLONBOARD200467REVASPINDLEMCGSERVOMOTOR2233-MT33840074740636CLEVELAND-KIDDEREC-2T600#M0-04497-30MO-04497-30HEIDENHAINENCODERINTERFACEEXE702BEXE702B***CELECTROPNEUMATICREGULATORITV2050-40N3BL4E/PREGUATLASCOPCOQMS340154240031181QMS340154240031115ESTICTNA1-TT01-SHNUTRUNNERTNA1TT01SHTNA1GEMSTRANSDUCERPSIBAR1200BGF600223DA001PROMESSPPMV1.2MONITORPANELMETERGEAUTOMOTIVEDUTY3PHMOTORAP5265KS145VSP300D101HPFOXBORO843DP-C2I1SSELECTRONICSTRAN***ITTER3000PSI36FOXBOROMAGNETICFLOWTRAN***ITTER8000SERIES8000-PA13LOTOF2EDWA***HIGHVACUUMFILTERA223-04-032A22DIAMONDPOWERSPECIALITYCOMPANYELECTRODE109077000ANKOBOLDVIBRATINGLEVELSWITCHNWSNWS-5220M12HYDACPRESSURETRAN***ITTERNIBHDA4000/HDA47004775-SOLARTRONMETROLOGYGAUGINGTRANSDUCERP25P)
