4. Configure PN/CAN-Gateway

The first slot entry after the ports is the slot for the CANopen® master parameters.

Set the 

CAN Bitrate

 and the 

CAN Master Node ID

. In some applications, a SYNC frame or heartbeat frame of the master is 

necessary for operation. 

The other "PN/CAN CO" slot entries contain no parameters.

5. Add CANopen® device

A "CANopen® device" is a CANopen® slave. An entry must be created for each CANopen® slave.
