Modbus protocole ni ururimi rusange rukoreshwa mugukoresha ibikoresho bya elegitoroniki.Binyuze muri protocole, abagenzuzi barashobora kuvugana hagati yabo hamwe nibindi bikoresho hejuru y'urusobe (nka Ethernet).Byahindutse inganda rusange.Iyi protocole isobanura umugenzuzi uzi imiterere yubutumwa bukoreshwa, utitaye kumurongo bavugana.Irasobanura uburyo umugenzuzi asaba kugera kubindi bikoresho, uburyo bwo gusubiza ibyifuzo bivuye mubindi bikoresho, nuburyo bwo kumenya no kwandika amakosa.Irerekana ubutumwa bwa domeni igishushanyo nuburyo busanzwe bwibirimo.Iyo ushyikirana numuyoboro wa ModBus, iyi protocole igena ko buri mugenzuzi agomba kumenya aderesi yibikoresho byabo, kumenya ubutumwa bwoherejwe na aderesi, no kumenya icyo ugomba gukora.Niba igisubizo gikenewe, umugenzuzi atanga ubutumwa bwo gutanga ibitekerezo akayohereza akoresheje ModBus.Kuyindi miyoboro, ubutumwa bukubiyemo protocole ya Modbus ihindurwa kumurongo cyangwa paki yububiko bukoreshwa kururu rusobe.Ihinduka kandi ryagura uburyo bwihariye bwurusobekerane rwo gukemura adresse yibice, inzira zinyuramo, no kumenya amakosa.Umuyoboro wa ModBus ufite host imwe gusa kandi traffic yose irayoborwa na we.Umuyoboro urashobora gushyigikira abagenzuzi ba kure bagera kuri 247, ariko umubare nyawo wabagenzuzi bayoborwa biterwa nibikoresho byitumanaho byakoreshejwe.Ukoresheje iyi sisitemu, buri PC irashobora guhanahana amakuru hamwe na host hagati itagize ingaruka kuri buri PC kugirango ikore imirimo yayo yo kugenzura.
Hariho uburyo bubiri bwo guhitamo muri sisitemu ya ModBus: ASCII (kode yo guhanahana amakuru muri Amerika) na RTU (Igikoresho cya kure).Ibicuruzwa byacu muri rusange bikoresha uburyo bwa RTU mu itumanaho, kandi buri 8Bit byte mu butumwa ikubiyemo inyuguti ebyiri za 4Bit.Inyungu nyamukuru yubu buryo nuko ishobora kohereza amakuru menshi kurwego rumwe baud kurenza uburyo bwa ASCII.
