1. Mfundo yaukadaulo: Mabasi a CAN amatengera mfundo yaukadaulo yowunikira kugawika kwa mikangano ndi nthawi yosawononga pang'ono, ndikulumikizana kudzera m'malo omwe ali m'basi kugawana sing'anga yotumizira (monga zopindika).EtherCAT imachokera ku teknoloji ya Efaneti, pogwiritsa ntchito dongosolo la kapolo-kapolo ndi njira yowulutsira mbuyeyo kuti akwaniritse kulankhulana kofanana kwa zipangizo zambiri za akapolo mkati mwa chimango cha Ethernet.

Kuthamanga kwa 2.Transmission: Kuthamanga kwa mabasi a CAN nthawi zambiri kumachokera ku kbps mazana angapo kufika ku 1Mbps zingapo, zomwe ndizoyenera zochitika zapakatikati ndi zotsika kwambiri.EtherCAT imathandizira kuthamanga kwambiri, nthawi zambiri kufika ku 100Mbps.Ngakhale kudalira luso lazowonjezera la EtherCAT G, chiwerengero chotumizira chikhoza kufika ku 1000Mbit / s kapena kupitilira apo, chomwe chili choyenera pa ntchito zothamanga kwambiri zomwe zimafuna kuyankhulana kwachangu.

3. Nthawi yeniyeni ndi kuyanjanitsa: EtherCAT ikhoza kuonetsetsa kuti nthawi yeniyeni yotumizira deta, ndipo kutumiza deta kumangolandira malire otetezeka pakati pa mafelemu awiri.Kulumikizana kwapadera kwa EtherCAT kungatsimikizire kuti node zonse zimayambitsidwa mofanana, ndipo nthawi ya jitter ya chizindikiro chogwirizanitsa ndi yochepa kwambiri kuposa 1us.

4.Data paketi kutalika malire: EtherCAT imadutsa malire a SDO paketi kutalika mu basi Can.

5. Njira yoyankhulirana: EtherCAT imatha kudutsa ma node angapo mumayendedwe amodzi, ndi ma adilesi a master station molingana ndi adilesi yomwe yakhazikitsidwa pa siteshoni iliyonse ya akapolo.Njira zoyankhulirana zitha kugawidwa mu: maadiresi owulutsa, maadiresi owonjezera, maadiresi okhazikika, ndi maadiresi omveka.Njira zoyankhulira za CAN zitha kugawidwa kukhala: maadiresi akuthupi ndi maadiresi owulutsa.

6.Topology: The CAN topology yomwe imagwiritsidwa ntchito kwambiri ndi mtundu wa basi;EtherCAT imathandizira pafupifupi ma topology onse: nyenyezi, mzere, mtengo, unyolo wa daisy, ndi zina zambiri, ndipo imathandizira njira zosiyanasiyana zoyankhulirana monga zingwe ndi ulusi wa kuwala.Imathandizanso The hot-swappable Mbali imatsimikizira kusinthasintha kwa kulumikizana pakati pa zida.

Kufotokozera mwachidule, muzogwiritsira ntchito encoder, pali kusiyana kwakukulu pakati pa mabasi a CAN ndi EtherCAT malinga ndi mfundo zaumisiri, liwiro la kutumiza, ntchito yeniyeni yeniyeni ndi kuyanjanitsa, zoletsa zapaketi ya data ndi njira zoyankhulirana, ndi mapangidwe a topology.Njira yoyenera yolumikizirana iyenera kusankhidwa potengera zosowa zenizeni ndi zochitika.
