ibicuruzwa

2.5 Imipaka Hariho imbogamizi nuburyo butandukanye bugomba kwitabwaho mugutegura kwishyiriraho. 2.5. Mubisanzwe byashyizwe hafi yundi kuberako guhuza cyangwa guhuza umurongo wa kabili uburebure. Niba sisitemu yawe ikoresha umugozi uhuza, uburebure bwayo bushyirwa kuri metero 3. Ubundi burebure bwa kabili ntibuboneka. Niba sisitemu yawe ikoresha icyerekezo, uburebure busanzwe bwa kabili kugeza kuri EPLCG ya kabiri ni 2m, ariko uburebure bwa kabili burahari. Ariko, niba insinga ndende ya relay ikoreshwa, amafaranga yongewe kumurongo wa relay panel agomba gukurwa muri buri nsinga ya Port 1 na Port 2. Ikigaragara ni uko uburebure bw'insinga isimbuza insinga bugomba kuba munsi ya metero 15 (metero 50). 2.5. Niba ushaka gukoresha Modbus protocole ya multidrop gahunda, ugomba gushyira modem yaho kuri EPLCG hamwe na modem ya kure ihujwe na buri PLCs murusobe. Allen-Bradley (AB) protocole ya multidrop gahunda buri gihe ihuza binyuze mugenzuzi w'itumanaho rya AllenBradley (CIM, kubijyanye n'itumanaho rya interineti). Kubera ko uyu mugenzuzi w'itumanaho atanga imiyoboro myinshi, hakenewe umugozi umwe gusa kuva ku cyambu cya EPLCG kugeza kuri AB mugenzuzi. 2.5.3 Uburebure bw'insinga Umugozi uva ku byambu bya EPLCG ntushobora kurenza metero 15 z'umugozi (metero 50 z'umugozi). Niba intera igana kuri PLC cyangwa umugenzuzi w'itumanaho irenze iyi mipaka, ugomba gukoresha modem-ngufi. Reba agace ka 2.6 kubitekerezo bya modem. Igenamigambi rya EPLCG, Kwinjizamo, na Serivisi2-10 5/01 2.5.4 2.5.4 Kwihuza mu buryo butaziguye Niba uhuza PLC imwe (cyangwa umugenzuzi w’itumanaho wa AB) kuri kimwe mu byambu kandi uburebure bwa kabili kuva EPLCG kugera kuri PLC buri munsi ya metero 15, ushobora gukoresha EIA-232 itaziguye (nta modem). Muri iyi gahunda, umugozi wa EIA-232 watanzwe na Honeywell ugomba kuba watsindiye umuhuza uhuza PLC yawe. Ibice 3.2.7 na 3.2.8 byerekana gahunda yo gukoresha insinga za kabili kubwoko butandukanye bwa PLC nibikoresho byimbere. 2.6. Nkuko byavuzwe haruguru, guhuza-kugarukira kugarukira kuri metero 15 ntarengwa ya metero hagati ya EPLCI I / O cyangwa ikarita ya Relay. Guhindura ibimenyetso ni ibikoresho bihindura ibimenyetso hagati ya EIA-232 EIA-422 cyangwa -485, kandi bikunze gukoreshwa mugutanga intera ndende cyangwa ibishushanyo byinshi. Modem ngufi-yerekana kwerekana ibyuma bya EIA-232 kuri EPLCG cyangwa PLC bisa nibyatanzwe na modem isanzwe ya terefone. Modem ngufi, ariko, ikoresha imirongo yabugenewe (ntabwo ari umurongo wa terefone) kandi irashobora gufata ubwisanzure hamwe na protocole ya interineti itemewe mu itumanaho rya terefone isanzwe. Modem isanzwe ya terefone ntabwo isanzwe ikoreshwa hamwe na EPLCG kuko igabanya cyane umurongo wa interineti, kandi umuvuduko wabo muto ukenewe (igipimo cya baud) ushobora gutesha agaciro imikorere ya EPLCG. EPLCG kandi ntishyigikira ibimenyetso byo guhana intoki bisanzwe bisabwa kuri modem, harimo Gusaba-Kohereza (RTS), Kugaragara-Kohereza (CTS), Gutwara Abatwara (CD), Data Set Ready (DSR), na Data Terminal Yiteguye (DTR). Ibikoresho bitandukanye nibikoresho bya kabili birashoboka. Menyesha umuhuza w'itumanaho inzobere cyangwa abacuruzi kubikoresho na cabling ikwiranye na porogaramu yawe.
