Communication profiles
Overview
This chapter describes the communication profiles used in the
communication between the DeviceNet network, the RDNA-01
module and the drive.
Communication profiles
Communication profiles are ways of conveying control commands
(Control word, Status word, references and actual values)
between the master station and the drive.
With the RDNA-01 module, the DeviceNet network may employ
either the ODVA AC/DC drive profile or the ABB Drives profile.
The ODVA AC/DC drive profile
This section briefly describes the ODVA AC/DC Drive profiles.

.
An DeviceNet node is modelled as a collection of abstract objects.
Each object represents the interface to and behaviour of a
component within the product. The ODVA AC/DC Drive Profiles
define a collection of objects suitable for the control of AC and DC
drives. Objects supported by the RDNA-01 DeviceNet Adapter are
listed in section
Class objects
on page

. Objects are defined by:
• Service
• Class
• Instance
• Attribute
• Behaviour
For example, to set the drive speed reference, the
Set_Attribute_Single service can be requested for Attribute
SpeedRef of the Class AC/DC Drive Object. The resulting
