Umehluko Phakathi Kwamakhadi Ememori Azinikele e-Siemens Namakhadi E-SD Ajwayelekile - Konke Okufanele Ukwazi

Zonke i-SIMATIC S7 series PLCs zihlonyiswe ngamakhadi ememori azinikele, futhi izinhlobo zamakhadi ziyahlukahluka ngokwemodeli: amakhadi e-MMC ochungechunge lwe-S7-300, amakhadi e-MC RAM kanye ne-MC Flash e-S7-400, amakhadi e-SMC ochungechunge lwe-S7-1200/1500, kanye namakhadi e-Micro-SD e-S7-200 SMART. Ikhadi ngalinye lememori linezici zokusebenza ezihlukile, futhi zibalulekile kwamanye amamodeli e-CPU. Lesi sihloko sichaza izici zamakhadi ememori e-S7 series PLCs.

1. Ikhadi le-SIMATIC MMC

I-MMC imele i-Micro Memory Card. Iyikhadi le-EPROM elinekhono lokugcina idatha ngokucima ugesi.

Ngaphakathi kwama-PLC ochungechunge lwe-S7-300, ikhadi le-MMC lisebenza njengememori yomthwalo. Njengoba amamojula e-CPU ochungechunge olusha lwe-S7-300 engafiki nememori yomthwalo eyakhelwe ngaphakathi, ikhadi le-MMC liyisisekeli esiyimpoqo sokusebenza.

2. Ikhadi le-SMC

Ikhadi le-SMC lifana namakhadi e-SD ajwayelekile futhi lingafundwa futhi libhalwe ngesifundi sekhadi le-SD esivamile. Kodwa-ke, imithetho yokusebenza eqinile kumele ilandelwe: amafayela afihliwe ekhadini akumelwe asuswe, futhi ikhadi le-SMC akumelwe lifomethwe ngesandla. Uma selifomethwe, ikhadi le-SMC lizoguqulwa libe ikhadi le-SD elijwayelekile futhi lilahlekelwe yimisebenzi yalo yezimboni. Amakhadi e-SD ajwayelekile ezentengiselwano awakwazi ukufaka esikhundleni sekhadi lememori elizinikele lama-CPU e-S7-1500.

Ukufometha amakhadi e-SMC kungenziwa kuphela ku-inthanethi nge-TIA Portal. I-Siemens ayikakhiphi isifundi samakhadi esizinikele samakhadi e-SMC, futhi abafundi abavamile bahlangabezana ngokugcwele nezidingo zokusetshenziswa kwansuku zonke.

3. Ikhadi le-MicroSD le-S7-1200

Ikhadi le-MicroSD elisetshenziswa yi-S7-1200 CPUs ligcina amafayela ephrojekthi yomsebenzisi futhi linikeza imisebenzi elandelayo ebalulekile:
  1. Sebenzisa njengememori yomthwalo we-CPU: Amaphrojekthi omsebenzisi angagcinwa kumemori khadi noma kwisitoreji sangaphakathi se-CPU. Uma kungekho phrojekthi elondolozwe ngaphakathi kwe-CPU, i-PLC ayikwazi ukusebenza ngaphandle kwememori khadi.
  2. Isebenza njengendlela yokudlulisa amafayela ephrojekthi kuma-PLC amaningi e-S7-1200 uma kungekho divayisi yokuhlela etholakalayo.
  3. Sula amaphrojekthi e-CPU yangaphakathi kanye namaphasiwedi okuvikela uma iphasiwedi ikhohliwe.
  4. Buyekeza inguqulo ye-firmware yama-CPU e-S7-1200 (amakhadi ememori kuphela anomthamo ongu-≥12 MB asekela lo msebenzi).

4. Ikhadi Lememori le-SIMATIC le-S7-1500

Ama-CPU e-S7-1500 asebenzisa amakhadi ememori e-SIMATIC njengemidiya yokugcina uhlelo, enemisebenzi eyinhloko ebhalwe ngezansi:
  1. Sebenza njengememori yomthwalo we-CPU; i-CPU izohluleka ukusebenza uma ikhadi lememori selisusiwe.
  2. Sekela izibuyekezo ze-firmware zama-CPU e-S7-1500 kanye namamojula e-I/O aphakathi.
  3. Funda idatha yokuxilonga yesevisi yemishini.

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

Ama-CPU e-S7-200 SMART asekela amakhadi e-MicroSD ezentengiselwano anamakhono asekelwayo angu-4 GB, 8 GB kanye no-16 GB. Amakhadi angu-2 GB kanye no-32 GB awahambisani. Imisebenzi esekelwayo imi kanje:
  1. Ukudluliswa kohlelo okungaxhunyiwe ku-inthanethi
  2. Ukuthuthukiswa kwe-firmware ye-CPU
  3. Buyisela i-CPU kuzilungiselelo ezizenzakalelayo zasembonini
