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 1.xx (i.e., 1.20 or earlier) for the

Ultra3000.
