Object Data (attributes) are summarised in an object. These attributes describe

various properties of a DeviceNet device, and can be read and written via

the bus. Access see: Object Directory"

Object Directory The Object Directory contains all device parameters and current

processing data which are directly accessible via FHPP, field bus or CI.

The Object Directory is divided into a range which contains general

specifications on the device (device identification, manufacturer name

etc.) and communication parameters, as well as a range which describes

the specific device functions. The identification of an entry (object) of the

object directory takes place depending on access via:

FHPP−FPC: Parameter number PNU

CI: Index and Subindex

DeviceNet: Class, Instance, Attribute

PNU Parameter number as per FHPP−FPC

Slave address

(nodeaddress)

Each of the up to 64 stations in a DeviceNet network has its own MAC ID

(Media Access Control Identifier); component of the CAN identifier.
