Esimeni sanamuhla sezimboni esithuthuka ngokushesha, isidingo samanethiwekhi okuxhumana athembekile nasebenza kahle sibaluleke kakhulu kunangaphambili.Ukushintshwa kwe-Industrial Ethernetidlala indima ebalulekile ekuqinisekiseni ukudluliswa kwedatha okungenazihibe kanye nokuxhumana kwenethiwekhi ezindaweni zezimboni. Phakathi kwezinhlobo ezihlukahlukene zokushintshwa kwe-Ethernet yezimboni, amaswishi aphethwe agqama ngezici zawo ezithuthukile nokusebenza kwawo. Kulesi sihloko, sizobhekisisa izinzuzo zokushintshwa kwe-Ethernet yezimboni eziphethwe nokuthi kungani zibalulekile ezinhlelweni zesimanje zezimboni.
Amaswishi e-Ethernet yezimboni eziphethwe anikeza izinga eliphezulu lokulawula nokwenza ngokwezifiso kunamaswishi angalawulwa. Ngokushintsha okuphethwe, abalawuli benethiwekhi bangalungisa futhi balawule izilungiselelo zokushintsha, babeke phambili ithrafikhi, baqaphe ukusebenza kwenethiwekhi, futhi basebenzise izinyathelo zokuphepha. Leli zinga lokulawula libaluleke kakhulu ezindaweni zezimboni lapho ukwethembeka nokuphepha kwenethiwekhi kubalulekile.
Enye yezinzuzo eziyinhloko zokuphathwaukushintshwa kwe-Ethernet yezimboniamandla abo okusekela izici zekhwalithi yesevisi (QoS). I-QoS ivumela ithrafikhi yedatha ebalulekile ukuthi ibekwe phambili, iqinisekisa ukuthi ulwazi olubucayi ngesikhathi njengamasiginali yokulawula noma idatha yokuqapha ngesikhathi sangempela ibekwa phambili kunethrafikhi engabalulekile. Leli khono libaluleke kakhulu ezinhlelweni ezishintshayo nezilawulayo zezimboni, lapho ukuxhumana kwesikhathi sangempela kubalulekile ekugcineni ukusebenza kahle nokuphepha.
Ngaphezu kwalokho, amaswishi aphethwe ahlinzeka ngezici zokuphepha zenethiwekhi ezithuthukisiwe, ezihlanganisa izinhlu zokulawula ukufinyelela, ukuphepha kwembobo, nokusekelwa kwe-virtual LAN (VLAN). Lezi zinyathelo zokuphepha zisiza ukuvikela amanethiwekhi ezimboni ekufinyeleleni okungagunyaziwe, ukuphazamisa kanye nezinsongo ze-inthanethi ezingaba khona. Esikhathini sokuhlasela kwe-inthanethi kwezimboni ezikhulayo, izici zokuphepha eziqinile ezinikezwa amaswishi aphethwe zibalulekile ekuvikeleni ingqalasizinda ebalulekile kanye nedatha ebucayi.
Enye inzuzo yokushintshwa kwe-Ethernet yezimboni ephethwe ukusekelwa kwezivumelwano zokuphatha ezithuthukisiwe njenge-Simple Network Management Protocol (SNMP) kanye ne-Remote Monitoring and Control (RMON). Lawa maphrothokholi anika amandla ukuqapha kwenethiwekhi okusebenzayo, ukuthuthukiswa kokusebenza, nokuxazulula izinkinga, okuvumela abaphathi ukuthi bakhombe futhi baxazulule izinkinga ezingaba khona ngaphambi kokuthi zibe nomthelela ekusebenzeni. Ikhono lokuqapha ukude nokuphatha amanethiwekhi ezimboni linenzuzo ikakhulukazi ezikhungweni zezimboni ezinkulu namasistimu asabalalisiwe.
Ukwengeza, amaswishi aphethwe ahlinzeka ngokuguquguquka okukhulu kanye nokulinganisa, okuvumela ukudalwa kwezihloko zenethiwekhi eziyinkimbinkimbi kanye nokuhlanganiswa kwemishini ehlukahlukene yezimboni kanye nezivumelwano. Ukuthi ukuxhuma ama-PLC, ama-HMI, izinzwa noma ezinye izisetshenziswa zezimboni, amaswishi aphethwe ahlinzeka ngokusebenza okudingekayo ukuze kuhlangatshezwane nezidingo zenethiwekhi ezihlukene. Ukwengeza, ikhono lokuhlukanisa inethiwekhi usebenzisa ama-VLAN linika amandla ukuphathwa kwethrafikhi okuphumelelayo nokuhlukaniswa kwamadivayisi abalulekile noma amasistimu angaphansi.
Kafushane, izinzuzo ephethweukushintshwa kwe-Ethernet yezimbonizicacile. Kusukela ekulawuleni okuthuthukisiwe nokuvikeleka kuye emandleni okuphatha athuthukile kanye nokuvumelana nezimo, amaswishi aphethwe abalulekile ezinhlelweni zesimanje zezimboni. Njengoba amanethiwekhi ezimboni eqhubeka nokuthuthuka futhi anda, indima yamaswishi aphethwe ekuqinisekiseni ingqalasizinda yezokuxhumana ethembekile nephumelelayo izobaluleka kakhulu. Ngokuqonda izinzuzo zokushintshwa kwe-Ethernet yezimboni eziphethwe, amabhizinisi angenza izinqumo ezinolwazi lapho esebenzisa amanethiwekhi ezimboni aqinile naqinile.
