This section provides the DeviceNet conceptual diagram and how to change parameters.
6.10.1 Managing DeviceNet Data
In DeviceNet, all parameters and point tables are managed as objects, instances, and
attributes.
Aconceptual diagram is given below.
DeviceNet Units have the following ojbects.
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.
