ABBBAILEY1746N21769IQ32在选择PLC机型时，主要考虑下面几点：1.功能的选择。对于小型的PLC主要考虑I/O扩展模块、A/D与D/A模块以及指令功能（如中断、PID等）。2.I/O点数的确定。统计被控制系统的开关量、模拟量的I/O点数，并考虑以后的扩充（一般加上10%～20%的备用量），从而选择PLC的I/O点数和输出规格。3.内存的估算。用户程序所需的内存容量主要与系统的I/O点数、控制要求、程序结构长短等因素有关。一般可按下式估算：存储容量=开关量输入点数×10+开关量输出点数×8+模拟通道数×100+定时器/计数器数量×2+通信接口个数×300+备用量。4.分配I/O点。分配PLC的输入/输出点，编写输入/输出分配表或画出输入/输出端子的接线图，接着就可以进行PLC程序设计，同时进行控制柜或操作台的设计和现场施工。5.程序设计。对于较复杂的控制系统，根据生产工艺要求，画出控制流程图或功能流程图，然后设计出梯形图，再根据梯形图编写语句表程序清单，对程序进行模拟调试和修改，直到满足控制要求为止。6.控制柜或操作台的设计和现场施工。设计控制柜及操作台的电器布置图及安装接线图；设计控制系统各部分的电气互锁图；根据图纸进行现场接线，并检查。7.应用系统整体调试。如果控制系统由几个部分组成，则应先作局部调试，然后再进行整体调试；如果控制程序的步序较多，则可***行分段调试，然后连接起来总调。8.编制技术文件。技术文件应包括：可编程控制器的外部接线图等电气图纸，电器布置图，电器元件明细表，顺序功能图，带注释的梯形图和说明。MTRAPREPAIRHEIDENHAINROD4626180003012-0?3*USED*KEPCOEFX050T-1POWERSUPPLY*USED*HTMELECTRONICSFCM1-1202P-ARU4*USED*BIMBABF-041.156-RCYLINGER*USED*BANNER***2A31R*USED*SQUARED31111-400-44120VCOIL*USED*LOTOF2ALLENBRADLEY42182-800-01*USED*GENERALELECTRICCR120A04002AA(ASPICTURED)*USED*QUARTECH8551POWERSUPPLY2.0VDC,1.5AMP*USED*ALLENBRADLEY700-BX-440A110V*USED*ABBS223K10A*USED****CVFS2120-5DZ-02*USED*JOHNSONCONTROLSA350PS-2C*USED*FUJIELECTRICSC-2SN*USED*SUMITOMOAF-3100ACDRIVEAF3122-011-U*NEW*HONEYWELLRM7840L1075*NEWINABOX*STI44501-0500T5009*USED*PHOENIXCONTACTSKBI64/C64*USED*TURCKRK4.5T-6-RS4.5T/S653*USED*INDUSTRIALDEVICESNS3V105B-6-MP29?0-FE2*USED*ALLENBRADLEY1756-CNBSERIESDDATECODE06/02*FACTOR...FESTOMEH-5/2-1/8-L-B*USED*SICKUE10-3OS3D0*USED*WEGMOTOR00218EP3E145TC*NEW*HP2LOTOF3WINTERS32025B6BIMETALTHERMOMETER*NEWINA...DYNAPARSTD0001SPEEDINDICATOR*NEWINABOX*FUJIELECTRICUM15A-C01APCBOARD*USED*ENDRESSHAUSERDC11TEN-AA1151H?LB1*USED*BURLINGH-1STEMPERATURERANGE50TO300*USED*ASISXYCOM5015T-24VOPERRATORINTERFACE5015-B0010000..?.MUELLERSTREAM65N-ANI-6-1WAFERBUTTERFLYVALVE*USED*LOTOF3MILLTRONICSMSP-1MOTIONSENSINGPROBESENSOR...LIKAC80-Y-1024ANF-2?245L4*USED*PROPORTION-AIRQB1TFIC220PRESSURECONTROLVALVE*USED*ROSEMOUNTSCL-C-003-M2WATERQUALITYANALYZER*USED*ACME/STANDARDPOWERSPWS-2436120-240VINPUT*USED*WESTINSTRUMENTS2800M2800L01T1418H1?0*USED*SQUAREDC1861S1R29B*USED*LOTOF4OMRONLY2110/120VAC*USED*WERMA(GREEN)64120000LAMPBASEW/BULB*USED*MOOREINDUSTRIESIPT/4-20MA/3-15?PSIG/20PSI-FA1[DIN]*U...MUFFINMUSB1230V50/60HZ*USED*ASTECACV5N6-1POWERSUPPLY*USED*TBWOODSWF2SENSORLESSVECTORDRIVEWF2C5002-0D575V...PEPPERL+FUCHSNBB5-18GM40-Z3-?V1PROXIMITYSENSOR*USE...LOTOF2TURCKNI4-M12-AN6X-H1?141*USED*GENERALELECTRICCR124C028*USED*SQUARED9007-C62B2SERIESA*USED*OGURDCLUTCHRNB0.8KDC-90V*NEWOUTOFABOX*GEFANUCIC610MDL124A*USED*KUHNKE81.030.01SOLENOIDVALVE*USED*McDONELL&MILLER143800*NEWINABOX*KLOCKNERMOELLERZM-6-PKZ2*USED*EFECTORLK7022LEVELSENSOR*USED*IFMOT5013*USED*WINKLEELECTRICCO.4PB0-100AMPS*NEWOUTOFBOX*PEPPERL+FUCHSNBB5-18GM50-E0*USED*SOLAHEVI-DUTYHS22F750B*NEWINTHEBOX*KEPCORAX5-20KPOWERSUPPLY120/220-240V*USED*ARROWHARTAH6810GMANUALMOTORCONTROLLER*NEWINABO...BOBST704-1337-01PCBOARD*USED*ANAHEIMAUTOMATIONBLD72XCE-1*USED*Ort:VereinigteStaatenvonAmerikaCROUZETGNR25BCZ*NEW*Ort:VereinigteStaatenvonAmerikaCHROMALOXAR-519TEMPERATURECONTROL*NEWINABOX*Ort:VereinigteStaatenvonAmerikaJOHNSONCONTROLV46AC-10WATERPRESSURE150PSIGMAX.*U...Ort:VereinigteStaatenvonAmerikaALLENAIREA-5-120/60COIL*USED*Ort:VereinigteStaatenvonAmerikaCOOPERCWL2230FI*NEW*Ort:VereinigteStaatenvonAmerikaDEUBLIN1102-070-103*NEWINABOX*CLAROSTATDJA1N0565105UA*NEWINABOX*BALLUFFBKS-S49-1-PU-05*USED*RELIANCEELECTRIC57C385PROCESSORBATTERY*NEWINABO...NOTIFIERSUPERVISEDCONTROLMODULEFCM-1A*ORIGINALPAC...LEVITON5334-I*NEWINABOX*CONTOMATICSBMS-1N*USED*BAUMERES33AP2B*USED*MAC413A-BBA-DM-DJA?J-1JD*USED*GENERALELECTRICCOIL55-501336G004SERIESA460-480V...LOTOF5SIEMENSED41B02020AMPCIRCUITBREAKER*USED*FUJIELECTRICEG53A*NEW*INTERNATIONALPOWERIHC24-2.4POWERSUPPLY24VAC2.4A*...LUBRIQUIPMAXI-MONITORMARKIII163-310-000*NICE*YASKAWAERCJ-HME4BA-BNROBOTCONTROLLER*USED*PEPPERL+FUCHSNMB8-30GM85-US-?FE-V12*USED*PEPPERL+FUCHSNBN15-30GM60-A2?-V1*USED*LOTOF2ALLENBRADLEY42GRR-9003SER.APHOTOSWITCH*US...HONEYWELLMICROSWITCH301LS8*NEWINBOX*RELIANCEELECTRIC78095-TCONTACT*NEWINAFACTORYBAG...PRECISIONT-368*USED*AKAPPHOLLANDC700120*USED*TBWOOD'SMICRO-INVEVRTERXF***002-0BECLIPSEMM5/1.0MAGNET*NEWINABOX*FIREYER9105P5002*USED*VARIANMR-13-05*USED*SUTTONPRESSBLOWERPB45B*USED*CORCOM5VR1F7202EMIFILTER120/250V*USED*EUROTHERMCHESSELL4103C*USED*BOBST704-1095-03POWERSUPPLY*USED*ACTECHLINEVOLTAGEBOARD962-004*NICE*LANTECH55004101*USED*LIBERTYINDUSTRIESR-12340PCREV.2*USED*LANTECH55003202*USED*ALLENBRADLEY140M-C2E-B25SER.B*USED*SQUARED40566-041-51*USED*)
