CAN 2.0A thiab CAN 2.0B yog ob versions ntawm Controller Area Network (CAN) raws tu qauv. Lawv qhov sib txawv tseem ceeb yog hom thiab ntev ntawm cov kab lus.
Kev piav qhia
CAN 2.0A:
Standard Frame Format, tseem hu ua tus qauv ncej.
Siv ib qho 11-bit identifier, tseem hu ua cov lus ID.
Tag nrho cov ncej ntev yog luv, haum rau kev sib txuas lus cov ntaub ntawv yooj yim.
CAN 2.0B:
Extended Frame Format.
Txhawb nqa 29-bit identifiers, suav nrog 11-bit basic identifiers thiab 18-bit extended identifiers.
Lub thav duab ntev ntev dua, tso cai rau ntau cov nodes thiab cov ntaub ntawv xa mus rau hauv ntau lub network nyuaj.
Nta
CAN 2.0A:
Cov qauv thav duab yog qhov yooj yim thiab kev sib kis ceev ceev.
Nws yog feem ntau yog siv nyob rau hauv cov tshuab nrog ib tug me me ntawm cov nodes thiab yooj yim kev sib txuas lus yuav tsum tau.
CAN 2.0A:
Txhawb ntau tus cim thiab tso cai rau kev sib txuas lus nrog ntau cov nodes.
Txawm hais tias lub thav duab ntev yog nce, nws hloov tau yooj yim dua thiab haum rau cov tshuab uas xav tau kom xa cov ntaub ntawv loj lossis muaj cov network topologies nyuaj.
Daim ntawv thov
CAN 2.
CAN 2.
Feem ntau niaj hnub CAN controllers txhawb CAN 2.0B thiab rov qab siv tau nrog CAN 2.0Ib kab lus.
Hauv tib lub network, CAN 2.0A thiab CAN 2.0B cov kab lus tuaj yeem nyob ua ke ntev npaum li txhua cov kab hauv lub network txhawb CAN 2.0B.
