Kuso sonke isitshalo sokuxuba i-asphalt, ingxenye eyinhloko uhlelo lwayo lokulawula, oluhlanganisa i-hardware nesofthiwe. Ngezansi, umhleli uzokuyisa ekwakhiweni okuningiliziwe kwesistimu yokulawula yesitshalo sokuxuba i-asphalt.

Okokuqala, ingxenye yehadiwe iyashiwo. Isekethe yehadiwe ihlanganisa izingxenye eziyinhloko zesekethe kanye ne-PLC. Ukuze kuhlangatshezwane nezidingo zokusebenza kohlelo, i-PLC kufanele ibe nezici zejubane eliphezulu, isofthiwe enengqondo kanye nokulawula ukuma, ukuze inikeze amasignali alungile okulawula isenzo ngasinye sesitshalo sokuxuba i-asphalt.
Khona-ke ake sikhulume ngengxenye yesofthiwe. Ukuhlanganiswa kwesoftware kuyingxenye ebaluleke kakhulu yayo yonke inqubo yokuklama, futhi ingxenye eyisisekelo ukuchaza amapharamitha. Ngokuvamile, uhlelo lomdwebo wesitebhisi sokulawula kanye nohlelo lokususa iphutha kuhlanganiswa ngokwemithetho yokuhlela ye-PLC ekhethiwe, futhi uhlelo olulungisiwe luhlanganiswe kulo ukuze kuqedelwe ukuhlanganiswa kwesofthiwe.
