Uhlelo lokulawula isiteshi sephampu oluzenzakalelayo olusekelwe ku-PLC njengeyunithi yokulawula yendawo, i-ethernet yezimboni, izindawo zokusebenza, iseva yedathabhesi njengomongo wesistimu yokulawula inqubo yesikhathi sangempela esabalalisiwe, ukwenza ukwakhiwa kokwaziswa kohlelo lokulawula isiteshi sokumpompa, ukutholwa kwedatha, idatha. ukudluliswa, ukugcinwa kwedatha, umbuzo wedatha, ukulawulwa kokuvula/ukuvala, ukuphathwa kwabasebenzi ukudidiyelwa kohlelo lokulawula ulwazi lwesimanje; Uhlelo lokulawula okuzenzakalelayo lwesiteshi sephampu lunganikeza isimo sokusebenza kwesikhathi sangempela esinembile seyunithi, isimo se-alamu yesikhathi sangempela kanye nokulawulwa kwe-anti-misoperation logic, okunganciphisa kakhulu ukungahambi kahle nokusebenza kancane kwabasebenzi bokuphatha ukusebenza. Thuthukisa ukuthembeka kokuphathwa kokusebenza kwesiteshi sephampu.
