• discard old messages
In the CAN-Ethernet-CAN Bridge mode the Expert mode of the Master can be configured individually for the
connection to each connected Slave.
CAN Tunnel
With two CANbridge NT 420 it is possible to transmit messages between two Classic CAN networks via a CAN
FD network (CAN tunnel). Only two identifiers are necessary for the CAN FD network. Via these two CAN FD
messages all Classic CAN messages are transferred. The busload on the tunnel can be reduced due to the usage
of the maximum length of 64 bytes. The Tx message identifier of the CAN FD tunnel port of the first device must
be configured according to the Rx message identifier of the CAN FD tunnel port of the second device and vice
versa.
IMPORTANT
If hexadecimal values are used, they must begin with 0x.
Example: 0x55
1. To activate a CAN tunnel via CAN FD between two devices, in the configuration tree select General and
select enabled in the field Use of CAN tunnel.
• CAN Tunnel is enabled in the configuration tree.
2. In the configuration tree select CAN Tunnel.
Figure 6. CAN tunnel settings
3. In drop-down list Tunnel Port select the transmitting port for the CAN FD messages.
4. In drop-down list Classic Port select the transmitting port for the Classic CAN messages.
• Classic CAN messages from the Classic Port are collected and transmitted as CAN FD messages from the
Tunnel Port to the second device.
5. In field Tx message identifier enter the identifier of the CAN FD message to be transmitted in decimal or
hexadecimal values.
6. In field Rx message identifier enter the identifier of the received CAN FD message in decimal or
hexadecimal values.
7. In field timeout specify the maximum time until the CAN FD message is transmitted (even if the 64 bytes are
not filled yet).
8. In Mapping Table configure the Classic CAN messages to be transmitted from the defined Classic Port to the
defined Tunnel port.
9. Select tunnel in column Tx Channel and define the Classic CAN messages.
