2.5 Imikhawulo Kunemikhawulo ethile kanye nezinketho ezimbalwa okufanele zicatshangelwe lapho uhlela ukufaka kwakho. 2.5.1 Imikhawulo Engokwenyama Kuhlelo lwe-EPLCG olungadingekile, amamojula e-EPLCG ayisisekelo nawesibili ngokuvamile ahlala endaweni yokubeka efanayo, kodwa awakwazi ukutholakala kumojuli efanayo yamanodi amabili. Ngokuvamile zifakwa eduze kwenye ngenxa yemikhawulo yobude bekhebula lephaneli ye-interlink noma edluliselwe. Uma isistimu yakho isebenzisa ikhebuli ye-interlink, ubude bayo bumi kumamitha angu-3. Obunye ubude bekhebula abutholakali. Uma isistimu yakho isebenzisa iphaneli edluliselwe, ubude bekhebula obujwayelekile ukuya ku-EPLCG yesibili bungu-2m, kodwa obunye ubude bekhebula buyatholakala. Kodwa-ke, uma kusetshenziswa ikhebula lephaneli elidluliswayo ende, inani elingezwe kukhebula yephaneli edluliswayo kufanele likhishwe kukhebuli ngayinye Yechweba Loku-1 ne-Port 2. Ngokusobala, ubude bekhebuli yephaneli edluliselwe esikhundleni kufanele bube ngaphansi kwamamitha angu-15 (amafidi angu-50). 2.5.2 Ikhebula elilodwa uma liqhathaniswa ne-Multidrop Kumelwe kube nekhebula elilodwa kuphela elisuka echwebeni liye ku-PLC, imodemu, noma isilawuli sezokuxhumana leso mbobo okufanele siseviswe. Uma ufuna ukusebenzisa ilungiselelo le-multidrop lephrothokholi ye-Modbus, kufanele ubeke imodemu yasendaweni ku-EPLCG enamamodemu akude axhunywe ku-PLC ngayinye kunethiwekhi. Amalungiselelo ephrothokholi ka-Allen-Bradley (AB) amaningi ahlala exhumeka ngesilawuli sezokuxhumana se-AllenBradley (i-CIM, Yemojula Yesixhumi Esibonakalayo). Njengoba lesi silawuli sezokuxhumana sihlinzeka ngoxhumo lwama-multidrop, kudingeka ikhebula elilodwa kuphela ukusuka embobeni ye-EPLCG ukuya kusilawuli se-AB. 2.5.3 Ubude bekhebula Izintambo ezisuka ezimbotsheni ze-EPLCG azikwazi ukuba zinde kuno-15 wamamitha wekhebula (50 cable-feet). Uma ibanga eliya ku-PLC noma isilawuli sezokuxhumana lidlula lo mkhawulo, kufanele usebenzise amamodemu e-shorthaul. Bheka isigatshana 2.6 ukuze uthole ukucatshangelwa kwemodemu.
