O le suʻega PD o mea autu o suʻega mo le faʻaogaina o meafaigaluega eletise, ma o le faʻamalo o le vaega taua o le lelei o meafaigaluega eletise. O le suʻesuʻega e faʻavae i luga o le modularization, faʻatulagaina o vaega faʻataʻitaʻiga e avea ma faʻasologa masani e tusa ai ma galuega eseese. O modules e mafai ona faʻaopoopo pe tape e tusa ai ma manaʻoga o tagata faʻaoga. O le module o le tulaga masani Europa, lea e faigofie mo le tausiga ma le faʻafouina. E faʻaaogaina le faʻaogaina o meafaigaluega faʻapitoa, ma le NI card mai Amerika National Instrument. E faʻaaogaina foʻi le faʻaogaina o numera ma isi masini faʻagasologa e aoina ma auʻiliʻili le faailo PD.
