详情描述：

1746-HCA1746-HCA1746-HCA由于浮点DSP的浮点运算用硬件来实现，可以在单周期内完成，因而其处理速度大大高于定点DSP，这一优点在实现高精度复杂算法时尤为突出。定点的计算不过是把一个数据当作整数来处理，通常AD采样来的都是整数，这个数相对于真实的模拟信号有一个刻度因子，大家都知道用一个16位的AD去采样一个0到5V的信号，那么AD输出的整数除以2^16再乘以5V就是对应的电压。在定点DSP中是直接对这个16位的采样进行处理，并不将它转换成以小数表示的电压，因为定点DSP无法以足够的精度表示一个小数，它只能对整数进行计算。而浮点DSP的优势在于它可以把这个采样得到的整数转换成小数表示的电压，并不损失精度（这个小数用科学记数法来表示），原因在于科学记数法可以表示很大的动态范围的一个信号，以IEEE754浮点数为例，单精度浮点格式：[31]1位符号[30-23]8位指数[22-00]23位小数。这样的能表示的小的数是+-2^-149,大的数是+-（2-2^23)*2^127，动态范围为20*log(大的数/小的数）=1667.6dB这样大的动态范围使得在编程的时候几乎不必考虑乘法和累加的溢出，而如果使用定点处理器编程，对计算结果进行舍入和移位则是家常便饭，这在一定程度上会损失精度。   AEG Modicon POS 001 6051-042.218343AEG Modicon POS 112-01MTS-Sensor Temposonics TTM-RB-M-0750-RAEG Modicon POS 112MTS-Sensor Temposonics TTM-RB-M-0750-RAEG Modicon KOS 882 167619MTS-Sensor Temposonics TTM-RB-M-0750-RSEW Eurodrive SH37/T DR63L4/THBosch SG-B1.016.060-00.010 ServomotorABB M2AA080B Drehstrom-K?figl?ufermotor 3GAA082002-ASASiemens Simatic S5 6ES5 242-1AA13 6ES5242-1AA13 E:2Siemens TELEPERM C M74003-A170 M74003-A 170Verteilergetriebe V 140 FO ATEKKegelradgetriebe L 23 BA 30Mattke DC-Servomotor RX 320 ER 1100 RX320ER1100Siemens Simatic S5 6ES5 312-3AB12 6ES5312-3AB12INDRAMAT DRF1.1M DRF 1.1 M KarteSiemens Simatic S5 6ES5430-UA13 6ES5 430-UA13Beckhoff C9900-U120Leuze FRK 85/4-800 L.1 RefelxionslichttasterSIEMENS Reader Control Computer RCC 990-01 FORCESEW Eurodrive WA37/T DRS71M4/TFFesto Ventilinsel CPV-14-VI + 4x S402 & 4x S302AEG Modicon ADU 205 424-270397Klaschka YKE/F/N-1.31 YKEFN131Siemens Simatic S5 6GK1143-0TA01 6GK1 143-0TA01Stoz Pumpe EF-N-2 F69 Kühl und SchmiermittelpumpeSEW EURODRIVE MC07A015-5A3-4-00AEG VPU 852 239668 B500SEW Eurodrive R47 DT71D4/BMGSICK WT 30-21SIEMENS Micromaster 6SE6420-2AB17-5AA1 6SE6 420-2AB17SEW Eurodrive R40 DT80N4TFSEW Eurodrive S57 DT80K4/TFSiemens TD10 6AV3971-1BA02-0CA0 6AV3 971-1BA02-0CA0Siemens Simatic S5 6ES5 301-5CA12 6ES5301-5CA12 E-StINDRAMAT DAA1.1 Karte DAA 1.1SF37 DY71S/B/TH IM3ASEW Eurodrive SF37 DY71S/B/TH IM3BSiemens Simatic S5/ Vipa DEA-BG07Festo CPA10-IFB-CP 173510B307Getriebebau Nord Getriebemotor SK 71L/4Pepperl + Fuchs UC2000-30GM-E6R2-V15 Ultraschall-SensAEG Modicon A 500 ALU 286AEG Modicon A 500 ALU 021AEG SEA 832 B 500 InterfaceAEG SFC 6504SICK FGSE750-21 Empf?nger für LichtvorhangAEG DAP002 DAP 002AEG DEP 012 DEP012Lenze 8200 vector E82EV551_4C E82EV5514CSEW-Eurodrive R40DT80N4 GetriebemotorSiemens Simatic S5 6ES5454-7LB11 6ES5 454-7LB11 6ES5454Phoenix Contact Interbus IBS RL 400 MLR R DIO 6/1 LKSICK C40S-1803DA10 Lichtvorhang SenderSICK C20E-180303A22 Lichtvorhang Empf?ngerSiemens Simatic S5 6ES5 312-3AB11 6ES5312-3AB11 E:4SEW-Eurodrive SA 32 DT 63L4/BO3 Getriebemotor SA32DT63Siemens Teleperm C M74003-A428SEW Eurodrive S57 DT80K4/TFRITTAL 47/72153/001 Bediengeh?use Command PanelSiemens Simatic S5 6ES5 925-3SA11 6ES5925-3SA11 E: 9Lenze Type: EMZ2002-ESiemens Simatic S5 6ES5 926-3SA11 6ES5926-3SA11 E: 8SEW EURODRIVE Movitrac 31CO14-503-4-00 + EMV-Modul EF01Siemens Simatic S5 6ES5 925-3SA11 6ES5925-3SA11 E:5TURCK Profibus DP SDPB-0800D-007SEW Eurodrive R47 DT71D4/BMG/TH/ZSiemens Simatic S5 6ES5465-4UA13 6ES5 465-4UA13SIEMENS SIMATIC S5 6ES5 955-3LF11 6ES5955-3LF11Siemens Simatic S5 6ES5923-3UA11 6ES5 923-3UA11Siemens Simatic S7 6ES7461-0AA01-0AA0 6ES7 461-0AA01-0ASIEBERT SX300-0580R-1-S0-A LED-Anzeige Industrie DisplSEW-Eurodrive PSKF 622 EPH 07/20/14 GetriebeSiemens 6SE3290-0DC87-2RA0 BremswiderstandSIEMENS SINUMERIK 6FX1128-1BA00 6FX1 128-1BA00SEW-Eurodrive PSKF 622R EPH 07/20/15Getriebebau Nord NORDAC SK 3000/3 CT 3,0 kW inkl.
