IC698CRE030IC698CRE030IC698CRE030PLC有两种基本的工作模式，即运行(RUN)模式与停止(STOP)模式。在运行模式，PLC通过反复执行反映控制要求的用户程序来实现控制功能。为了使PLC的输出及时地响应随时可能变化的输入信号，用户程序不是只执行一次，而是不断地重复执行，直至PLC停机或切换到STOP工作模式。除了执行用户程序外，在每次循环过程中，PLC还要完成内部处理、通信处理等工作，一次循环可分为5个阶段（见图1-5）。PLC的这种周而复始的循环工作方式称为扫描工作方式。由于计算机执行指令的速度极高，从外部输入-输出关系来看，处理过程似乎是同时完成的。◆企业名称：厦门泰尼电气有限公司◆主营业务：DCS,PLC◆经营模式：贸易◆贸易地区：***◆联系人：小黄《女士》◆电话：0592-6809319◆手机：18950191386◆***:2917675397◆传真：0592-6890859（备注“01006”收）◆E-mail：2917675397@***.comALLENBRADLEY1771-QDC/D1771QDCALLENBRADLEY1771-QDC/D1771QDCDOLANJENNERLPCS-3COLORSCANNERNEWLPCS3BAUMULLER922-06321SERVOMOTOR92206321ABBACS401600435ACDRIVENIBBOSCH3-842-999-761ITEM3842999761PILLARTECHNOLOGIESDB6339-7CONTROLBOARDNEWDB6339RAYTHEON3256564VOLTAGEREGULATOR6110012558676ALLENBRADLEY1785-L40CWITH1785-ENETFISCHER&PORTER50KM2111A1XB1CHAMELONCONTROLLERNIBSIEMENS/MOORE39P***NANAPACSP***MODULE16013-1R/10SIEMENS/MOORE39VIMCBNAPACSVIMMODULE16171-121R/05TEXASINSTRUMENTSCVU-3604KEYBOARDCVU3604MODICONAS-J810-000INTERFACEMODULEASJ810000RELIANCE0-51845-1PRSBNIBSEALED0518451RELIANCE0-51865CLDACARD051865ALLENBRADLEY809-A16ERELAY809A16EVIKINGVK102HIGHTEMPSPRINKLERPENDENTLOT(64)INDUSTRYPACK68300-07MODULE6830007TRIANGLE90WB8007AYANALOGBOARDPARKERCOMPUMOTORZETA8STEPPERDRIVETRIANGLE90WB8005AGBAGBOARDTRIANGLE90WB8009ASSCALEBOARDTRIANGLE90WB8009ATSCALEBOARDFOXBOROMODEL121-RECHARTRECORDER121REMICRISTARMODEL828DIGITALPROCESSCONTROLLERMODICONAS-B243-105CONVERTERMODULEASB243105SIEMENS/MOORE39P***NANAPACSP***MODULE16013-1/2MELITTELFUSEKLLU-2000FUSELOTNIBKLLU2000SIEMENS6ES5-312-5CA21INTERFACEMODULENEW6ES53125CA2WIKA12774503STAINLESSTRAN***ITTERNEWWIKA12774503STAINLESSTRAN***ITTERNEWWIKA12514187STAINLESSTRAN***ITTERNEWWIKA12514187STAINLESSTRAN***ITTERNEWACROMAG***ME-9471VIRTUALMEMORYMODULE***ME9471MACSTAINLESSSOLENOIDVALVEMANIFOLDASSEMBLYJCSYSTEMSA1970/1270TEMPERATURECONTROLLERBOARDALFA-L***AL***U2ASPEEDMONITORINGUNIT551-131-20ALLENBRADLEY5150-RS5150-MRSREMOTESCANNER5150RS51GEFANUCA06B-0512-B004ACSERVOMOTORA06B0512B004BODINE48Y6BFPPMOTORWITHBOSCH3-842-503-069REDUCERBODINE48Y6BFPPMOTORWITHBOSCH3-842-503-069REDUCERPIERELECTRONICSA10-6VMBOARDA106VMYASKAWACIMR-F7U47P5ACDRIVECIMRF7U47P5RELIANCE0-51847-4VLDECARDNIB0518474RELIANCE0-50007-RTHYRATHONRECTIFIER050007RALLENBRADLEY1336S-B015-AE-EN41336SB015AEEN4SIEMENS500-6870PROFIBUS-DPREMOTEBASECONTROLLERMODSIEMENS500-6870PROFIBUS-DPREMOTEBASECONTROLLERMODELECTROCAMPS-5101-10-016NIBPS510110016SIEMENS505-7101BASICMODULENEW5057101YASKAWACIMR-F7U43P7ACDRIVECIMRF7U43P7MAGNETEKCIMR-G5U41P5DRIVECIMRG5U41P5RELIANCE0-51381-16CONTROLLERCARDNEW05138116SQUARED52011-022-50POWERINTERFACEBOARD5201102250HONEYWELLDR4502CHARTRECORDERDR4502110000000000W111TIMKENSAL-2-11/16PILLOWBLOCKBEARINGNIBSAL21116SIEMENS/MOORE39SDM024DCCANAPACSSDMMODULE16101-121/SIEMENS/MOORE39P***NANAPACSP***MODULECTCATM-4505-0ACCESS4000MODULEATM45050FOXBOROE11GMTRAN***ITTERNIBYASKAWACIMR-G7U42P2DRIVECIMRG7U42P2BLHELECTRONICSDXP-10TRAN***ITTERDXP10AMSCONTROLSMODEL6390SPLITTERMODULENIB)
