Kusiyana Pakati pa Makhadi Okumbukira Odzipereka a Siemens ndi Makhadi Achizolowezi a SD - Zonse Zomwe Muyenera Kudziwa

Kusiyana Pakati pa Makhadi Okumbukira Odzipereka a Siemens ndi Makhadi Achizolowezi a SD - Zonse Zomwe Muyenera Kudziwa

Ma SIMATIC S7 series PLC onse ali ndi makadi okumbukira apadera, ndipo mitundu ya makadi imasiyana malinga ndi mtundu: makadi a MMC a S7-300 series, MC RAM ndi MC Flash card a S7-400, makadi a SMC a S7-1200/1500 series, ndi makadi a Micro-SD a S7-200 SMART. Khadi lililonse lokumbukira lili ndi mawonekedwe apadera, ndipo ndi ofunikira kwambiri pa mitundu ina ya CPU. Nkhaniyi ikufotokoza makhalidwe a makadi okumbukira a S7 series PLCs.

1. Khadi la SIMATIC MMC

MMC imayimira Micro Memory Card. Ndi khadi la EPROM lomwe limatha kuzima deta.

Mkati mwa ma PLC a S7-300 series, khadi la MMC limagwira ntchito ngati chikumbutso chokweza katundu. Popeza ma module a CPU a mndandanda watsopano wa S7-300 samabwera ndi chikumbutso chokweza katundu chomangidwa mkati, khadi la MMC ndi chowonjezera chofunikira pakugwiritsa ntchito.

2. Khadi la SMC

Khadi la SMC limafanana ndi makadi a SD ndipo limatha kuwerengedwa ndi kulembedwa kudzera mu wowerenga khadi wa SD wamba. Komabe, malamulo okhwima ogwirira ntchito ayenera kutsatiridwa: mafayilo obisika pa khadi sayenera kuchotsedwa, ndipo khadi la SMC siliyenera kukonzedwa pamanja. Likakonzedwa, khadi la SMC lidzasinthidwa kukhala khadi la SD wamba ndipo lidzataya ntchito zake zonse zapadera. Makhadi a SD wamba ogulitsa sangalowe m'malo mwa khadi la memory loperekedwa la S7-1500 CPU.

Kukonza makadi a SMC kungachitike pa intaneti kudzera pa TIA Portal. Siemens sinatulutse makina owerengera makadi a SMC, ndipo owerenga nthawi zonse amakwaniritsa zofunikira pakugwiritsa ntchito tsiku ndi tsiku.

3. Khadi la MicroSD la S7-1200

Khadi la MicroSD lomwe limagwiritsidwa ntchito ndi ma S7-1200 CPU limasunga mafayilo a polojekiti ya ogwiritsa ntchito ndipo limapereka ntchito zofunika izi:
  1. Chitani ngati chikumbutso cha katundu cha CPU: Mapulojekiti ogwiritsa ntchito amatha kusungidwa pa khadi la memori kapena mu malo osungira amkati a CPU. Ngati palibe pulojekiti yosungidwa mkati mwa CPU, PLC singagwire ntchito popanda khadi la memori.
  2. Imagwira ntchito ngati njira yosamutsira mafayilo a polojekiti ku ma S7-1200 PLC angapo pamene palibe chipangizo chopangira mapulogalamu.
  3. Chotsani mapulojekiti amkati mwa CPU ndi mawu achinsinsi oteteza ngati mawu achinsinsi ayiwalika.
  4. Sinthani mtundu wa firmware wa ma S7-1200 CPU (makadi okumbukira okha omwe ali ndi mphamvu ≥12 MB ndi omwe amathandizira ntchitoyi).

4. SIMATIC Memory Card ya S7-1500

Ma CPU a S7-1500 amagwiritsa ntchito makadi okumbukira a SIMATIC ngati malo osungira mapulogalamu, ndipo ntchito zazikulu zalembedwa pansipa:
  1. Gwirani ntchito ngati load memory ya CPU; CPU idzalephera kugwira ntchito khadi la memory likachotsedwa.
  2. Thandizani zosintha za firmware za ma S7-1500 CPU ndi ma central I/O modules.
  3. Werengani zambiri zokhudza matenda a chipangizocho.

5. Khadi la MicroSD la S7-200 SMART

Ma CPU a S7-200 SMART amathandiza makadi a MicroSD amalonda omwe ali ndi mphamvu zothandizidwa za 4 GB, 8 GB ndi 16 GB. Makadi a 2 GB ndi 32 GB sagwirizana. Ntchito zothandizira ndi izi:
  1. Kutumiza pulogalamu popanda intaneti
  2. Kusintha kwa firmware ya CPU
  3. Bwezeretsani CPU ku zoikamo za fakitale
