Kubintu byose bivanga asfalt, igice cyibanze ni sisitemu yo kugenzura, ikubiyemo ibyuma na software. Hasi, umwanditsi azakujyana muburyo burambuye bwa sisitemu yo kugenzura uruganda ruvanga asfalt.

Mbere ya byose, igice cyibikoresho kivugwa. Ibyuma byumuzunguruko birimo ibice byingenzi byumuzunguruko na PLC. Kugirango wuzuze ibisabwa muri sisitemu, PLC igomba kugira ibiranga umuvuduko mwinshi, software ya logique no kugenzura imyanya, kugirango itange ibimenyetso byiteguye kugenzura buri gikorwa cyuruganda ruvanga asfalt.
Noneho reka tuvuge igice cya software. Gukusanya software ni igice cyingenzi cyibikorwa byose, kandi igice cyibanze ni ugusobanura ibipimo. Muri rusange, gahunda yo kugenzura logic urwego rwerekana igishushanyo mbonera na gahunda yo gukemura byakozwe hakurikijwe amategeko agenga porogaramu ya PLC yatoranijwe, kandi porogaramu yaciwemo iyinjizwamo kugirango irangize icyegeranyo cya software.
