616 Fieldbus control through the embedded fieldbus interface (EFB)
About the control profiles
A control profile defines the rules for data transfer between the drive and the fieldbus
master, for example:
• if packed boolean words are converted and how
• how drive register addresses are mapped for the fieldbus master.
You can configure the drive to receive and send messages according to the ABB
Drives profile or the Transparent profile. With the ABB Drives profile, the embedded
fieldbus interface of the drive converts the control word and status word to and from
the native data used in the drive. The Transparent profile involves no data
conversion. The figure below illustrates the effect of the profile selection.
Note that scaling of references and actual values can be selected independent of the
profile selection by parameters 58.26…58.29.
