Iikhowudi eziphambili zokufumana kunye nokuhlaziya idatha efana neqondo lokushisa, ukufuma, kunye nokuphakama kwi-interface engundoqo, kunye nokusebenzisa i-modbus rtu ukulawula iimodyuli zokulawula ubushushu, ii-motor, ukufunyanwa kwe-alamu, kunye nabanye oomatshini bekhoboka ngolu hlobo lulandelayo.
