442 Fieldbus control through the embedded fieldbus interface (EFB)
Basics of the embedded fieldbus interface
The cyclic communication between a fieldbus system and the drive consists of 16-bit
data words or 32-bit data words (with the transparent control profiles).
The diagram below illustrates the operation of the embedded fieldbus interface. The
signals transferred in the cyclic communication are explained further below the
diagram.

2. Data conversion if parameter 58.25 Control profile is set to ABB Drives. See section About the control
profiles (page 446).
3. If parameter 58.25 Control profile is set to Transparent,
• the sources of the status word and actual values are selected by parameters 58.30…58.32 (otherwise,
actual values 1 and 2 are automatically selected according to reference type), and the control word is
displayed by 06.05 EFB transparent control word.
