374 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 a transparent control profile).
The diagram below illustrates the operation of the embedded fieldbus interface. The
signals transferred in the cyclic communication are explained further below the
diagram.
