2. Overview

The Dynamic Node Allocation (DNA) functionality in POWERLINK is used to set the node number of a node from

the managing node over the network. This application note will describe how to set the node number of an

Anybus CompactCom 40 POWERLINK via DNA using B&R Automation Studio.

NOTE

DNA is supported by the Anybus CompactCom 40 POWERLINK from firmware version 1.17.

NOTE

To enable the DNA functionality in the Anybus CompactCom 40 POWERLINK, the value of the node

number in the Network Configuration Object (Instance #1) must be set to 0.

I.e. if a switch for setting Node ID is present on the application it must be set to 0.

NOTE

Make sure the PLC and the used B&R Automation Studio version supports the DNA functionality.

Two different topologies will be described, Line topology and Star topology.

Nodes with built-in hub are connected in a line, and the node number can be set on all nodes via DNA if

supported.

NOTE

Nodes with DNA enabled can not be used together with nodes not supporting DNA or with DNA

disabled.
