Basics Of The Fieldbus Control Interface - ABB +N5600 Firmware Instructions

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

1) See also other parameters which can be controlled from fieldbus.
2) The maximum number of data words used is protocol-dependent.
3) Profile/instance selection parameters. Fieldbus module specific parameters. For more
information, see the User's Manual of the appropriate fieldbus adapter module.
4) With DeviceNet, the control part is transmitted directly.
5) With DeviceNet, the actual value part is transmitted directly.
