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.
