Fieldbus control through the embedded fieldbus interface (EFB) 371About the control profilesA control profile defines the rules for data transfer between the drive and the fieldbusmaster, for example:• if packed boolean words are converted and how• if signal values are scaled and how• how drive register addresses are mapped for the fieldbus master.You can configure the drive to receive and send messages according to one of thetwo profiles:• ABB Drives• DCU Profile.For the ABB Drives profile, the embedded fieldbus interface of the drive converts thefieldbus data to and from the native data used in the drive. The DCU Profile involvesno data conversion or scaling. The figure below illustrates the effect of the profileselection.Profile selectionControl profile selection with parameter 58.25 Control profile is:• (0) ABB Drives• (5) DCU Profile.58.25SELDataconversion &scaling05Fieldbus Drive58.26…58.29
