This section provides the DeviceNet conceptual diagram and how to change parameters.
In DeviceNet, all parameters and point tables are managed as objects, instances, and
attributes.
Aconceptual diagram is given below.
Connection Object (0x05)
Instance #2
DeviceNet Units have the following ojbects.
No. of

1
Manages the physical connection to the DeviceNet.
1
Manages responses.
2
Mangages commands.
100
Manages Explicit Messages.
101
Manages I/O messages.

Manages detailed motion settings.
1
Manages point table data.
1
Manages Servo Driver paramters.
1
Manages the settings of the data trace function.
1 to 4
Manages trace data.
Instances within objects hold data called attributes and show the status of the DeviceNet
Unit. If referencing or changing attributes via DeviceNet, you must specify the object name,
instance number, and attribute number.
For example, when referencing via DeviceNet the DeviceNet Unit parameter Pn802 (Origin
Search High Speed), specify the attribute as follows:
• Control Parameter Object (0x64), Instance #1, Attribute #12
Refer to 10.2 DeviceNet Attributes for a table of attributes.
