Basics Of The Fieldbus Control Interface - ABB ACS880 N5700 Series Firmware Manual

Basics of the fieldbus control interface

The cyclic communication between a fieldbus system and the drive consists of 16-
or 32-bit input and output data words. The drive is able to support a maximum of
12 data words (16 bits) in each direction.
Data transmitted from the drive to the fieldbus controller is defined by parameters
