Mang kapa mang ea kileng a sebetsa lefapheng la indasteri o tla tseba hore li-switches tsa indasteri li bitsoa li-switch Ethernet tsa indasteri. Li-switch tsa Industrial Ethernet ke tseo re atisang ho li bitsa li-switch tsa indasteri. Li-switches tsa indasteri ke li-switches tsa indasteri tse etselitsoeng ka ho khetheha ho fihlela litlhoko tsa lits'ebetso tse fetohang le tse fetohang tsa indasteri. thepa, e fanang ka tharollo ea puisano ea Ethernet ea indasteri e theko e boima. Ka hona, li-switches tsa indasteri li tumme haholo indastering. Har'a tsona, selikalikoe se na le phapang pakeng tsa lesale le le leng le li-multi-ring, hape ho na le liprothokholo tsa lesale tsa poraefete tse entsoeng ke baetsi ba li-switches tse fapaneng tsa indasteri motheong oa STP le RSTP, joalo-joalo. Joale melemo ea mantlha ea tekheniki ea li-switches tsa indasteri ke efe?
Li-switch tsa indasteri li na le melemo e latelang:
1. Theknoloji ea marang-rang ea "zero" ea ho iphekola ho finyella botšepehi bo phahameng le botšepehi ba phetisetso ea data
Pele ho sena, nako e potlakileng ea ho iphekola ea li-switches tsa indasteri lefatšeng e ne e le 20 milliseconds. Leha ho le joalo, ho sa tsotellehe hore na nako ea ho iphekola ea phoso ea marang-rang ea lesale e khutšoanyane hakae, e tla baka tahlehelo ea lipakete tsa data nakong ea phetoho, e ke keng ea mamelloa ka lera la taelo ea taolo. Ha ho pelaelo hore ho ipholisa ho fihlela katleho ho mahlale a teng mme ho netefatsa ts'epo e phahameng le ts'epo ea data.
Phetoho ea indasteri e etsa bonnete ba hore ha marang-rang a hlōleha, kamehla ho na le tataiso e le 'ngoe ea ho fihla moo ho eang teng ka ho phalla ha data ka mahlakoreng a mabeli, ho netefatsa boitsebiso bo sa sitisoeng ba taolo.
2. Marang-rang a mofuta oa libese a hlokomela ho kopanngoa ha marang-rang le mohala
Marang-rang a libese a lumella basebelisi ho iketsetsa sesebelisoa se laoloang. Ka ho tšoara terminal e tšoanang ea Mac e le sesebelisoa se ts'oanang, sesebelisoa se nka sesebelisoa se laoloang e le sesebelisoa se ts'oanang, e le hore lisebelisoa tsena li hokahane le tlhaiso-leseling e arolelanoang, e netefatsang khokahano ea taolo. .
Li-switch tsa indasteri li tšehetsa mefuta e fapaneng ea liprothokholo tsa libese le li-interface tsa I/O ho hlokomela marang-rang a data ea libese. Ho e-na le mokhoa o sa tloaelehang oa ntlha-to-point, eketsa ts'ebeliso ea lisebelisoa tsa marang-rang le libese. Ho feta moo, tlhophiso ea marang-rang e feto-fetohang e ka phethahala, e ka kopanngoang ka ho toba le lisebelisoa tsa tšimo tse kang lisebelisoa le lik'hamera tsa indasteri, e le hore PLC e ka kopanngoa le lisebelisoa tsa I / O tse hōle, tse fokotsang haholo palo ea PLC tsamaisong eohle le. e fokotsa haholo litšenyehelo tsa ho kopanya tsamaiso. . Ntle le moo, li-switches tsa indasteri li ka kopanngoa le software ea ho shebella marang-rang ka Web le SNMP OPC Server ho lekola boemo ba node ka nako ea nnete, le ho ba le ts'ebetso ea alamo ea phoso ho thusa ho hlokomela le ho laola hole.
3. Ka potlako le ka nako ea sebele
Li-switch tsa indasteri li na le karolo ea bohlokoa ea data, e lumellang basebelisi ho etsa lisebelisoa tse itseng e le lisebelisoa tsa data tse potlakileng. Ha data e potlakileng e hlaha ka har'a marang-rang a reng, data e tloaelehileng e tla etsa sebaka sa data e potlakileng. Qoba boemo ba hore li-switches tsa setso li ke ke tsa sebelisoa ho karolo ea taolo ea taolo ka lebaka la tieho e feteletseng ea data
