Iindaba

1. Umgaqo wobuchwephesha: Ibhasi ye-CAN ithatha umgaqo wobugcisa wokufumanisa ungquzulwano olusasazwayo kunye nexesha elingonakalisi le-bit, kwaye linxibelelana ngeenodi kwibhasi ekwabelwana ngayo i-transmission medium (efana ne-twisted pair).I-EtherCAT isekelwe kwi-teknoloji ye-Ethernet, isebenzisa isakhiwo se-master-slave kunye ne-master broadcast method to achieve the synchronous communication of multiple slave devices ngaphakathi kwesakhelo se-Ethernet.

I-2.Isantya sothumelo: Isantya sothumelo lwebhasi ye-CAN ngokuqhelekileyo sisuka kumakhulu ambalwa e-kbps ukuya kwii-1Mbps ezininzi, ezilungele iimeko zesicelo esiphakathi kunye nesezantsi.I-EtherCAT ixhasa isantya esiphezulu sothumelo, ngokuqhelekileyo sifikelela kwi-100Mbps.Nokuba uthembele kwi-teknoloji ye-EtherCAT G eyongezelelweyo, izinga lokudluliselwa lingafikelela kwi-1000Mbit / s okanye ngaphezulu, efanelekileyo kwizicelo ezikhawulezayo ezifuna ukunxibelelana ngokukhawuleza kwangempela.

3. Ixesha langempela kunye nokuvumelanisa: I-EtherCAT inokuqinisekisa ukuhanjiswa kwedatha yexesha langempela, kwaye ukuhanjiswa kwedatha kwamkela kuphela umda wexesha elikhuselekileyo phakathi kwezakhelo ezimbini.Ulungelelwaniso olukhethekileyo lwe-EtherCAT lunokuqinisekisa ukuba zonke ii-nodes ziqhutywe ngokuhambelanayo, kwaye ixesha le-jitter yesiginali yokuvumelanisa lingaphantsi kwe-1us.

I-4.Umda wepakethe yedatha: I-EtherCAT iphula umda kwi-SDO ubude bepakethe kwi-Can ibhasi.

5. Imo yedilesi: I-EtherCAT inokunqumla ii-nodes ezininzi kwi-transmission enye, kunye ne-master station idilesi ngokwedilesi ebekwe kwisikhululo samakhoboka ngasinye.Iindlela zeedilesi zinokwahlulwa zibe: idilesi yosasazo, idilesi yokwandisa ngokuzenzekelayo, idilesi yendawo esisigxina, kunye nedilesi enengqiqo.Iindlela zokujongana nodidi lwe-CAN zinokwahlulwa zibe: idilesi yendawo kunye nedilesi yosasazo.

I-6.Topology: I-CAN topology esetyenziswa ngokuqhelekileyo luhlobo lwebhasi;I-EtherCAT ixhasa phantse zonke ii-topology: inkwenkwezi, umgca, umthi, ikhonkco le-daisy, njl., kwaye ixhasa imidiya eyahlukeneyo yonxibelelwano efana neentambo kunye neentambo zokukhanya.Ikwaxhasa i-hot-swappable feature iqinisekisa ukuguquguquka koqhagamshelwano phakathi kwezixhobo.

Ukushwankathela, kwizicelo ze-encoder, kukho ukungafani okukhulu phakathi kwebhasi ye-CAN kunye ne-EtherCAT ngokwemigaqo yezobugcisa, isivinini sokuhambisa, ukusebenza kwexesha langempela kunye nokuvumelanisa, izithintelo zepakethi yedatha kunye neendlela zokujongana, kunye nezakhiwo ze-topology.Iprotocol yonxibelelwano efanelekileyo kufuneka ikhethwe ngokusekelwe kwiimfuno zokwenyani kunye neemeko.
