338 Control through the embedded fieldbus interface
About the EFB communication profiles
A communication profile defines the rules for data transfer in between the drive and
the fieldbus master, for example:
• if packed boolean words are converted and how
• if the signal values are scaled and how
• how the drive register addresses are mapped for the fieldbus master.
You can configure the drive to receive and send messages according to one of the
four profiles: the ABB Drives classic profile, ABB Drives enhanced profile, 16-bit DCU
profile or 32-bit DCU profile. For either one of the ABB Drives profile, the embedded
fieldbus interface of the drive converts the fieldbus data to and from the native data
used in the drive. Both DCU profiles are transparent, that is, no data conversion is
done. The figure below illustrates the effect of the profile selection.
