Kubwuruganda ruvanze cyane, igice cyibanze ni sisitemu yo kugenzura, ikubiyemo ibyuma nibice bya software. Umwanditsi hepfo azagutwara muburyo burambuye bwa sisitemu yo kugenzura station ya Asfalt.
Ikintu cya mbere tuvuga nigice cyibyuma. Umuzunguruko w'ibyuma urimo ibice byibanze na PLC. Kugirango duhuze imikorere ya sisitemu, PLC igomba kugira ibiranga umuvuduko mwinshi, imikorere, software ya logique no kugenzura imyanya, kugirango bitanga imirimo itandukanye kubihingwa bivanga. Kugenzura urugendo rutanga ibimenyetso byo kwitegura.

Ibikurikira, reka tuganire kubice bya software. Gukusanya software nigice cyingenzi cyane mubikorwa byose, ibyingenzi byibanze bisobanura ibipimo. Mubihe bisanzwe, gahunda yo kugenzura urwego hamwe na gahunda yo gukemura hamwe hakurikijwe amategeko ya porogaramu ya PLC yatoranijwe, kandi gahunda yo gutesha agaciro yinjijwemo kugirango irangize gutegura software.
