Fieldbus control through the embedded fieldbus interface (EFB) 357
 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.
 Control word and Status word
The Control Word (CW) is a 16-bit or 32-bit packed boolean word. It is the principal
means of controlling the drive from a fieldbus system. The CW is sent by the fieldbus
controller to the drive. With drive parameters, the user selects the EFB CW as the
