DeviceNet distinguishes between three types of objects: communication
objects, system objects and application specific objects.
.
Communication objects define the data exchanged via DeviceNet, they
are also called connection objects.
.
System objects define general DeviceNet specific data and function which
are useful for most DeviceNet devices.
.
Application specific objects define device-specific data and functions.
The data and the executed services of an object are addressed via a hierar-
chical address concept using the following identifiers:
.
Device address (MAC ID)
.
Class ID
.
Instance ID
.
Attribute ID
.
Service Code
