Umahluko phakathi kweeKhadi zeMemori ezinikezelweyo zeSiemens kunye neeKhadi zeSD eziqhelekileyo - Konke okufuneka ukwazi

Zonke ii-SIMATIC S7 series PLCs zixhotyiswe ngamakhadi ememori azinikeleyo, kwaye iintlobo zamakhadi ziyahluka ngokwemodeli: amakhadi e-MMC ochungechunge lwe-S7-300, amakhadi e-MC RAM kunye ne-MC Flash oluhlu lwe-S7-400, amakhadi e-SMC oluhlu lwe-S7-1200/1500, kunye namakhadi e-Micro-SD oluhlu lwe-S7-200 SMART. Ikhadi ngalinye lememori lineempawu ezizodwa zokusebenza, kwaye azinamsebenzi kwezinye iimodeli ze-CPU. Eli nqaku lichaza iimpawu zamakhadi ememori oluhlu lwe-S7 series PLCs.

1. Ikhadi le-SIMATIC MMC

I-MMC imele iMicro Memory Card. Likhadi le-EPROM elikwaziyo ukucima idatha.

Ngaphakathi kwee-PLC ze-S7-300 series, ikhadi le-MMC lisebenza njengememori yomthwalo. Ekubeni iimodyuli ze-CPU zechungechunge olutsha lwe-S7-300 zingafiki nememori yomthwalo eyakhelwe ngaphakathi, ikhadi le-MMC liyimfuneko yokusebenza.

2. Ikhadi le-SMC

Ikhadi le-SMC lifana nekhadi le-SD eliqhelekileyo kwaye linokufundwa kwaye libhalwe ngesifundi sekhadi le-SD esiqhelekileyo. Nangona kunjalo, kufuneka kulandelwe imithetho engqongqo yokusebenza: iifayile ezifihliweyo kwikhadi akufuneki zicinywe, kwaye ikhadi le-SMC akufuneki lifomethwe ngesandla. Nje ukuba lifomethwe, ikhadi le-SMC liya kuguqulwa libe yikhadi le-SD eliqhelekileyo kwaye lilahlekelwe yimisebenzi yalo yoshishino. Amakhadi e-SD aqhelekileyo orhwebo awanakukwazi ukuthatha indawo yekhadi lememori elinikezelweyo kwi-S7-1500 CPUs.

Ukufometha amakhadi e-SMC kungenziwa kwi-intanethi kuphela nge-TIA Portal. I-Siemens ayikhupheli isifundi sekhadi esizinikeleyo samakhadi e-SMC, kwaye abafundi abaqhelekileyo bayahlangabezana ngokupheleleyo neemfuno zokusetyenziswa kwemihla ngemihla.

3. Ikhadi le-MicroSD le-S7-1200

Ikhadi le-MicroSD elisetyenziswa yi-S7-1200 CPUs ligcina iifayile zeprojekthi zomsebenzisi kwaye libonelela ngemisebenzi ebalulekileyo elandelayo:
  1. Sebenzisa njengememori yomthwalo weCPU: Iiprojekthi zomsebenzisi zinokugcinwa nokuba kwikhadi lememori okanye kwindawo yokugcina yangaphakathi yeCPU. Ukuba akukho projekthi igciniweyo ngaphakathi kweCPU, i-PLC ayinakusebenza ngaphandle kwekhadi lememori.
  2. Isebenza njengesixhobo sokudlulisa iifayile zeprojekthi kwii-PLC ezininzi ze-S7-1200 xa kungekho sixhobo sokuprograma esifumanekayo.
  3. Cima iiprojekthi zeCPU zangaphakathi kunye namagama okugqitha okukhusela ukuba igama lokugqitha lilibalekile.
  4. Hlaziya inguqulelo ye-firmware yee-S7-1200 CPUs (kuphela amakhadi ememori anomthamo we-≥12 MB axhasa lo msebenzi).

4. Ikhadi leMemori leSIMATIC le-S7-1500

Ii-CPU ze-S7-1500 zisebenzisa amakhadi ememori e-SIMATIC njengezixhobo zokugcina iinkqubo, kunye nemisebenzi ephambili edweliswe ngezantsi:
  1. Sebenza njengememori yomthwalo yeCPU; iCPU ayizukusebenza xa ikhadi lememori lisusiwe.
  2. Xhasa uhlaziyo lwe-firmware kwii-CPU ze-S7-1500 kunye neemodyuli ze-I/O eziphambili.
  3. Funda idatha yokuxilonga yenkonzo yezixhobo.

5. Ikhadi le-MicroSD le-S7-200 SMART

Ii-S7-200 SMART CPUs zixhasa amakhadi e-MicroSD orhwebo ane-4 GB, 8 GB kunye ne-16 GB exhaswayo. Amakhadi e-2 GB kunye ne-32 GB awahambelani. Imisebenzi exhaswayo yile ilandelayo:
  1. Ukusasazwa kwenkqubo ngaphandle kwe-intanethi
  2. Ukuphuculwa kwefirmware yeCPU
  3. Buyisela i-CPU kwizicwangciso ezimiselweyo zasefektri
