IXXAT CANopen Device Manager
5.1 Working with the Network List
To scan for CANopen devices in a network, click the Scan Network button. This will display a dialog box which enables
the user to specify the range of node-IDs that shall be scanned for actively connected CANopen devices. The scan will
attempt to detect connected CANopen devices by uploading a predefined set of object dictionary entries from each
possible device within the specified node-ID range, beginning with the mandatory object 1000h Device type (see CiA
301 for a description of the CANopen device type).
Note that the scan will only commence provided that either a CAN network interface has been configured prior
to the scan operation or is in parasite mode. If not, the CAN configuration dialog is opened and the user is
prompted to configure an adequate CAN channel.
The user may also specify if the scan operation shall include all node-IDs in the specified range, or only devices that
have not yet been added to the data storage representing the current CANopen network configuration (default).
Depending on the specified scan range, the scan process may take several seconds. During the scan process,
CANopen Device Manager will not only attempt to detect connected CANopen devices, but also upload device
parameters like identification objects, information related to supported NMT error control mechanisms and
configured SDO and PDO communication objects. For a complete list of scanned object dictionary entries, see the
table below.
