Programming Reference
The Ultra3000 Drive with DeviceNet implements a vendor specific
device profile - Rockwell Automation Miscellaneous (Device Type:
73hex).
The configuration data and behaviors implemented in the Ultra3000
Drive with DeviceNet are defined using object modeling. The
Ultra3000 Drive with DeviceNet is modeled as a collection of objects.
An Object is a collection of related attributes and services. An attribute
is an externally visible characteristic or feature of an object, while a
service is a procedure an object can perform.
The following general definitions also may be useful in understanding
DeviceNet object modeling:
• Object - A representation of a particular type of data component
within the DeviceNet node.
• Instance - A specific occurrence of an Object.
• Attribute - A description of a characteristic or feature of an Object.
Attributes provide status information or govern the operation of an
Object.
• Service - A function performed by an Object.
This manual documents the DeviceNet object models implemented in
DeviceNet firmware versions 2.xx for the Ultra3000 drives.
