Gateways and Bridges/Router

open up a variety of connection possibilities


With bridges and gateways CAN or CAN FD systems can be coupled or implemented over a larger area, devices without CAN can be connected to CAN systems or CAN systems can be coupled using different technologies, e.g. Bluetooth, Ethernet or PROFINET.

Gateways and Bridges


Expand your system 

Bridges and gateways enable larger system expansions and increase the reliability of your system.


Cloud connection

MQTT cloud connection enables remote monitoring and alarms (CAN@net NT).


Save costs

Easier wiring and reduction of cables reduces the cost of your system.


Action rules

Execution of various actions using event-triggered rules (CAN@net NT & CANbridge NT).


Data manipulation

Filter and conversion functionality reduces network load and simplifies interconnection of various devices.



Bridging of large distances, easy system access and retrofitting of old devices using Bluetooth, Ethernet, PROFINET, CAN and CAN FD.


RS232-CAN converter

With the CAN-GW100/RS232, devices with a serial RS232 port can be connected to the CAN bus. Two modes are available for use in CAN and CANopen networks.

How it works

In the CAN mode (layer 2), the received CAN data is transmitted transparently to the RS232 interface. Data sent by means of RS232 is packed in CAN telegrams. One configurable identifier is available for each transmission and reception. 

In CANopen mode the CAN-GW100/RS232 works as a CANopen subscriber, where the serial data is saved as a bytestream object in the manufacturer-specific object dictionary range.

CAN bridges and CAN gateways are infrastructure components with which complex network structures can be implemented.

A CAN bridge can connect CAN or CAN FD networks of different bit rates or protocols with each other. It is based on the store-(modify)-forward principle where CAN / CAN FD messages are received by a sub-network and then transmitted to the other sub-network. Translation and filter rules can also be used, allowing a protocol adaptation to be carried out between the sub-networks. Unlike the CAN / CAN FD repeater, the CANbridge enables the enlargement of the maximum network size so that the sub-systems are fully self-sufficient with regard to bus arbitration. Independent of each other in terms of their real-time behavior, CAN sub-networks connected by bridges are to be regarded as independent networks.

The bridge function can also be executed with the aid of other transmission systems. For example, the CAN-Ethernet-CAN bridge is connected via two Ethernet-TCP/IP gateways which enable connection to remote CAN / CAN FD networks.

As an extension to the CAN bridges, CAN gateways allow for access to CAN networks via other communication systems. In each case, the protocols of the connected bus systems are mapped to the other communication model.

Application samples:

CAN bridge
Using the CANbridge NT, CAN or CAN FD systems within a building can be separated for every flor, due to this the maximum system expansion can be easily extended.

CAN Bridge Application Sample

CAN gateway
CAN@net NT allows large distance coupling of CAN or CAN FD systems via Ethernet, e.g. for connecting the engine room with the control room on a ship.
