10.6 CANopen NodeScanner Tab
When analyzing a CANopen network, the CANopen Node Scanner tab can be used to automatically detect active CANopen nodes on the network based on the received boot-up messages. The window provides the user NMT functionality to easily control the found nodes.
By right-clicking on the window and choosing Reset the user can clear the window of found nodes. Found nodes will be displayed again when new boot up messages are received.
