UKUkhwezwa OKUDE I-FCP270 icaba futhi yenze lula ukwakheka kwe-Foxboro Evo Process Automation System, edinga kuphela izivalo zenkundla kanye neziteshi zokusebenza namaswishi e-Ethernet. Ukuze uthole ulwazi olwengeziwe mayelana nesakhiwo senethiwekhi yokulawula i-MESH, bheka ku-PSS 21H-7C2 B3. I-FCP270 efakwe ensimini iyingxenye ebalulekile yenethiwekhi yokulawula esabalaliswe kakhulu lapho abalawuli baqondaniswe eduze namayunithi enqubo athile afakwe eduze ne-I/O yabo kanye nezisetshenziswa zangempela ezilawulwayo. Ukuxhumana phakathi kwamayunithi enqubo kwenzeka nge-fiber optic 100 Mbps Ethernet network. I-FCP270 ipakishwe endlini emagebhugebhu, eyi-die cast aluminium engadingi ukushaywa umoya ngenxa yomklamo wayo osebenza kahle. I-FCP270 inesitifiketi se-CE, futhi ingafakwa ngaphandle kwamakhabethe akhethekile abizayo ukuvimbela ukukhishwa kwe-electronic. I-FCP270 ingafakwa ku-Class G3 ezindaweni ezinokhahlo. UKWETHEMBEKA OKUTHUTHUKISIWE (UKUBEKEZELA AMAPHUTHA) Ukusebenza okuyingqayizivele nokunelungelo lobunikazi lokubekezelela amaphutha kwe-FCP270 kuthuthukisa kakhulu ukuthembeka okuhlobene nezinye izilawuli zenqubo. Inguqulo ebekezelela amaphutha ye-FCP270 inamamojula amabili asebenza ngokufana, anokuxhumana kwe-Ethernet okubili kunethiwekhi yokulawula ye-MESH. Amamojula amabili e-FCP270, ashade njengepheya elibekezelela amaphutha, ahlinzeka ngokusebenza okuqhubekayo kwesilawuli esimweni lapho kwenzeka khona noma yikuphi ukwehluleka kwezingxenyekazi zekhompuyutha phakathi kwemojuli eyodwa yokubhangqa. Womabili amamojula athola futhi acubungule ulwazi kanye kanye, futhi amaphutha atholwa amamojula ngokwawo. Enye yezindlela ezibalulekile zokuthola amaphutha ukuqhathanisa imiyalezo yokuxhumana kumamojula okusebenzelana kwangaphandle. Imilayezo ishiya kuphela isilawuli uma zombili izilawuli zivumelana ngomlayezo othunyelwayo (i-bit for bit match). Lapho kutholwa iphutha, ukuzihlola kwenziwa yiwo womabili amamojula ukuze kutholwe ukuthi iyiphi imojula enesici. Imojula engenasici ibe isithatha ukulawula ngaphandle kokuphazamisa ukusebenza kwesistimu evamile. Lesi sixazululo esibekezelela iphutha sinezinzuzo ezinkulu ezilandelayo ngaphezu kwezilawuli ezivele zingasebenzi kakhulu:  Ayikho imilayezo emibi ethunyelwa enkundleni noma ezinhlelweni zokusebenza kusetshenziswa idatha yesilawuli ngoba awukho umlayezo ovunyelwe ukuphuma kusilawuli ngaphandle uma womabili amamojula ehambisana nebhithi nebhithi kumlayezo othunyelwayo.  Isilawuli sesibili sivunyelaniswa nesesiyinhloko, esiqinisekisa kuze kube manje uma kwenzeka ukwehluleka kwesilawuli esiyinhloko.  Isilawuli sesibili sizoba namaphutha acashile atholwe ngaphambi kwanoma yikuphi ukushintsha ngoba senza imisebenzi efanayo ncamashi nesilawuli esiyinhloko. I-SPLITTER/COMBINER Amamojula e-FCP270 abekezelela iphutha axhumeka kupheya ye-fiber optic splitter/combiners (bona Umfanekiso 1) axhumeka kumaswishi e-Ethernet ku-MESH. Kumojula ngayinye, ipheya yesihlukanisi/inhlanganisela inikeza ukuxhumana okuhlukene kokudlulisa/ukwamukela ifayibha ye-Ethernet switch 1 no-2. Izintambo ze-Fiber zixhunywe ukuze isihlukanisi/abahlanganisi kudlule ithrafikhi yangaphakathi kusuka kunoma iyiphi inkinobho kuya womabili amamojula, futhi kudlule ithrafikhi ephumayo kusukela kumojula eyinhloko kuya kunoma iyiphi inkinobho. Ipheya yesihlukanisi/inhlanganisela igibeleka ekuhlanganiseni okunamathela kuma-baseplates e-FCP270. Isihlukanisi/inhlanganisela iyisisetshenziswa esingasebenzisi amandla kagesi. UKUXHUMANA OKUTHUTHUKISIWE Isakhiwo se-Foxboro Evo sisebenzisa inethiwekhi yokulawula ye-Mesh enokuxhumana kwedatha okungu-100 Mbps phakathi kwe-FCP270s namaswishi e-Ethernet (bona Umfanekiso 2).
