ABBAI830A3BSE040662R1当PLC的用户程序要保留在RAM中时,就会用到电池,电池通常是3V或3.6V的不可充电的锂电池,电池的使用寿命通常是五年左右,电池用久了,电压就会下降,当其下降到不足以保证RAM中数据时,RAM中的程序就会丢失。如果用户没有备份程序,就会相当麻烦。一般PLC内部设有电池电压检测电路,当电压下降到一定程度时,PLC就会报警,提醒更换电池。PLC的使用说明书都有提供更换电池的方法。一般来说,PLC在断电后,因为PLC上RAM电源端接有充电电容,即使把电池去掉,电容上充电电量也足够RAM内的数据保持一段时间,所以如果取掉电池后在短时间内(通常5分钟)再将新电池换上去,数据是不会丢失的。但用户实际使用PLC的环境情况不尽相同,例如电容的容量下降,RAM电源回路有灰尘、油泥等形成放电回路等,这会加快PLC断电后电容的放电速度,从而使时间不好把握。如果在带电的情况下更换电池就可保程序万无一失。因为电源始终会有电压加在RAM芯片的电源脚。当然更换时亦要小心应对,注意电池的极性以及避免短路情况发生。***好是把PLC通电15分钟(给内部电容充电),断电,在5分钟内换好新的电池,再上电试一下;西门子PLC有带卡的,有不带电池的;也有带卡的,带电池的。程序存在MMC卡中,如果没有存储卡,需要电池保存程序的,更换电池时候务必注意,带电的情况下,将旧电池取出来,然后将新电池换上即可。MM05C-503-00MVME5500-0161ARTMO-250VE2T8PCNDSAI130DDSAO120ADSBC176SGMAH-01AAA21IC697MDL740EADAM-5017ADAM-5050ADAM-5510140CRA931001756L55M223503E3700AMPL-A320H-HJ22AADKCXX.3-100-7PS4-201-MM1E4809-770-069AMVME167PA-34SEHE100S6FX1115-0AA026FX1123-7AA026FX1125-1AA016FC3988-7AF011756-OW16I1756-TBCH/ACACR-IR151515EBSDCSPOW-1PSSICPU302060PSSIDI20T302112PSSIDIOZ302108PSSIPS24302051C7012A12021326AB-B420E-M2L1747-CP3(USB)1747-CP3(串口)1747-L542IC693PBM200140DD035300140DDI35300140NOE77110TSXCTY4ATSXPBY100XBT-F034610PS-M06D12S5-NJ1L(S)A06B-0126-B5776ES7331-7KF02-OABO6ES7332-5HD01-OABO1756-CN21756-EWEB1756-IB321756-L631756-OF81756-OV32E972-0DP10MC-4/11/10/4001756-CNB1756-CNBR1756-ENBT1756-IF81756-IM16I1756-L631756-OF41756-OF81756-OW16I1756-PA721756-PA751756-TBCH1756-TBNH1757-SRMLOGO-230RC1746-IM161746-OW161746-P21747-L5411756-BA11756-IB321756-L55M131756-OB321756-PA72/C6ES7307-1EA00-0AAO6ES7315-2AF03-0AB06ES7317-2AJ10-0AB06ES7321-1BL00-0AA06ES7322-1BH02--0AA06ES7322-1BL00-0AA06ES7322-1HH01--0AA06ES7331-7KB02-0AB06ES7331-7KF02-0AB06ES7332-5HD01-0AB06ES7953-8LL00-0AA06ES7971-1AA00-0AA06SE7216-2BD23-OXB0VLT2822PT4B20SBR1DBF10A00C0OP-620621-6575ES1-112-7MTA03B-0801-C054A03B-0807-C161A06B-6114-H208A16B-1212-022A16B-2200-035A16B-2200-036A20B-2000-01702094-BC02-M02-S872C-D3NP12-D4PSR4/5A-2503TK2804-0BB43TK2907-0BB41746-NO8I1770-XYC1771-A2B1771-CD1771-P71794-ASB1794-IM81794-OM81794-TBNOP-620INNIS21INNPM12K-TFT-AN-CCFTFERE100SGDH-04AE140ACI04000140ACO02000140DDI35300140DDO35300140NOE77101N4010AR3767CGM2QA100L4B140ARI03010DDI-35300DDO-35300XB2-BVM3LCFX2N-4DA1746-IB161746-NI81746-NIO4I1746-OA161746-P41747-L5321756-CNBR440R-S35001SCXI-1000SCXI-1166SCXI-1327SCXI-1600DSO6012AA06B-6050-H050BC635PCI3A0350.6DSTC176KL1002KL2012A16B-1212-0210A16B-1212-0220A16B-2200-0350A16B-2200-0361A20B-2000-01703CP260。60-16468-2-061-001756-DNBTC-PRS021GP37W2-BG41HE693THM6651756-CNB/D1756-OW16I1756-TBCH/A140NOE77101PPC-105T1756-RM1756-RMC101786-RG61786-TPS1786-XTA06B-0075-B003FXM5-110A-20A602453-59AA06B-0075-B0033BSC610038R1SD8223BSC610039R1SD823KPC2004HDD,SHOCK-RESISTANTVER,ASSYUSB-STICK4GB5X00226G01EVS9325-ESEVS9327-ESEVS9328-ESL3MF-032/64GFOKS-G序列号S/N:11851FRN7.5P11S-4CXAS-B824-0161784PKTX6SN1123-1AB00-0BA2E6CP-AG5C2562MMCS40A0022-5A3-4-00140ACI03000140ACO0200043AP-FA45C/PB-BA1FK7081-5AZ91-1ZZ9-ZS042.5KW1FK7100-5AZ91-1ZZ9-ZS053.2KW1FK7101-5AZ91-1ZZ9-ZS074.2KW8.5AKPS-600/20-ESCKSD1-16KSD1-48开关电源1756-CNB1756-TBCH/A6***6642-0AA11-0AX1140NOE77100ATV312H075N4ATV31H075N4APS416-BGT-410P6153LPR-24VDC-UOP-620ACS510-01-017A-4FSU8IC693MDL655HKJ3001X1-CA1KJ3201X1-BA16DR5020-ONN01-OAAO=6DR5020-ONN00-OAAOTWDLCAA24DRF1757-SRM1756-ENBT/AFR-A740-15K-CHTC25DND2301/2NPT(M)/直径14*2材质304SSFR-8-1/8VL/O-3-1/4VZ-3-PK-3140AC013000140ACI04000140ACO02000140CPS11420140CPU11302140CRA21110140CRP81100140DAO85300140DDI35300140XBP016001394C-SJT22-DKEBA-HT4011394C-SJT22-DA16B-2201-0480A20B-2100-0790GPD515C-A080CIMR-G5U2018C7012G1019JZRCR-NPP01-130083503E36254119A43294351B8312D2-16ND3-21771-A2B1771-A3B11771-ASB/D1771-IAD/C1771-IFE/A1771-IXE/B1771-OAD/B1771-OFE2/B1771-P4S1771-P7/B1771-WI1785-L20B/CYB-05FC1SDCS-COM-5SDCS-PIN-205B6FC5501-0AB00-0AA01746-A131746-NI8PTQ-PDPMV16GK1900-0AB001746-IB32KL-16BTKL-16BXKL-2DASGMAS-08ACA612711P-T15C15D14WRAP6W7-04-21/24K4/MNW-RR85-001SGMGH-13ACA61A06B-0202-B1001756-A171756-A41756-CFM1756-DNB1756-ENBT1756-IB321756-IF4FXOF2F1756-IR6L1756-IT6I21756-L611756-OW16I1756-PA721756-PB751756-A101756-A71756-CNBR1756-ENBT1756-IB16D1756-IF161756-L62)
