Chero ani akamboshanda mundima yeindasitiri achaziva kuti maindasitiri ekuchinja anonzi maindasitiri eEthernet switch. Industrial Ethernet switches ndiyo yatinowanzo kudana maindasitiri switch. Maindasitiri anochinja machinjiro emaindasitiri akanyatso kugadzirirwa kusangana nezvinodiwa zvinoshanduka uye zvinoshanduka zvemaindasitiri maapplication. midziyo, iyo inopa inodhura-inoshanda maindasitiri Ethernet kutaurirana mhinduro. Naizvozvo, maindasitiri anochinja anonyanya kufarirwa muindasitiri iyi. Pakati pavo, mhete ine mutsauko pakati pemhete imwe chete uye yakawanda-mhete, uye kune zvakare yakavanzika mhete mapuroteni akagadzirwa neakasiyana maindasitiri switch vagadziri pahwaro hwe STP uye RSTP, zvichingodaro. Saka ndezvipi zvakakosha zvehunyanzvi zvakanakira zvemaindasitiri switch?
Industrial switches ine zvinotevera zvakanakira:
1. Zero self-healing ring network tekinoroji kuti uwane kuvimbika kwepamusoro uye kuvimbika kwekufambiswa kwedata
Izvi zvisati zvaitika, iyo inokurumidza kuzvirapa nguva yekuchinja kwemaindasitiri munyika yaive 20 milliseconds. Zvisinei, zvisinei kuti ipfupi sei nguva yekuzviporesa yemhete yemhete yemhete inokanganisa, ichaita zvisingadzivisiki kurasikirwa kwemapakiti e data panguva yekuchinja, iyo isingagoni kushivirira pamurairo wekuraira. Zero yekuzvirapa pasina mubvunzo inowana budiriro mune iripo matekinoroji uye inova nechokwadi chekuvimbika kwepamusoro uye kuvimbika kwedata.
Iyo maindasitiri switch inovimbisa kuti kana network ikatadza, panogara paine nzira imwe yekusvika kwainoenda kuburikidza nebidirectional data kuyerera, kuve nechokwadi chisina kukanganiswa chekudzora data.
2. Iyo bhasi-mhando network inoziva kubatanidzwa kwetiweki uye mutsara
Iyo network yebhazi inobvumira vashandisi kugadzirisa iyo inodzorwa mudziyo. Nekubata iyo yakafanana chaiyo Mac terminal sechinhu chimwe chete, switch inotora inodzorwa mudziyo sechinhu chimwe chete, kuitira kuti zvishandiso izvi zvibatanidzwe uye ruzivo rwakagovaniswa, izvo zvinova nechokwadi chekubatana kwekutonga. .
Maindasitiri anochinja anotsigira akasiyana siyana emabhazi maprotocol uye I/O interfaces kuona network yedata rebhazi. Panzvimbo peiyo isiri-yechinyakare point-to-point modhi, wedzera network uye mabhazi sosi yekushandisa. Uyezve, flexible network configuration inogona kuitika, iyo inogona kubatanidzwa zvakananga kune zvigadzirwa zvemumunda zvakadai sezviridzwa uye makamera emaindasitiri, kuitira kuti PLC igone kubatanidzwa kune I / O zvishandiso zviri kure, izvo zvinoderedza zvikuru nhamba yePLCs muhurongwa hwose uye inoderedza zvakanyanya mari yekubatanidza system. . Uye zvakare, machinjiro emaindasitiri anogona zvakare kubatanidzwa mune network yekutarisa software kuburikidza neWebhu uye SNMP OPC Server yekutarisa node mamiriro munguva chaiyo, uye kuve nekukanganisa alarm basa rekufambisa kure kuchengetedza uye manejimendi.
3. Fast uye chaiyo-nguva
Maindasitiri anochinja ane data rekutanga ficha, achibvumira vashandisi kugadzirisa mamwe maturusi seanokurumidza data zvishandiso. Kana data rinokurumidza richionekwa munetiweki yemhete, data yakajairwa ichaita nzira yekukurumidza data. Dzivisa mamiriro ezvinhu ekuti machinjiro echinyakare haagone kuiswa kune control command layer nekuda kwekunonoka kwedata
