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.

The LIN-CAN gateway is a universal device for both the analysis of LIN networks (Local Interconnect Network) via the CAN bus and for the emulation of LIN slave or master modules. In addition, the device can be used as a LIN-PC interface for PC-based configuration and monitoring software, or, for PC-supported LIN device development.

Gateway - LIN 2 CAN

Operation modes

The LIN-CAN Gateway supports four operating modes:

  • LIN-CAN Gateway as LIN Master or LIN Slave
  • LIN-Slave Emulation
  • LIN-Master-Slave Emulation
  • LIN-PC Interface

The various modes will be configured via PC. The configuration is saved as "non-volatile" in the device.

LIN CAN Gateway
The LIN-CAN Gateway mode allows the transparent transmission of LIN messages to a CAN network. The device works as a LIN master or LIN slave. Received LIN messages are passed on to CAN and the LIN identifiers are translated into CAN identifiers. The LIN data is passed on via the CAN object. The device also provides a transmit function to LIN via CAN. For this, CAN identifiers are translated into LIN identifiers and, when requested by a LIN master are transmitted once in the LIN network. The data of the CAN object is stored in a buffer and then transmitted as LIN data. PC programmable translation tables, which are stored on the device, are available for the translation of the messages.

LIN Slave Emulation
The LIN slave mode provides a stand-alone LIN slave emulation. The device has a configurable transmission table. When a LIN header is received, the stored data is transmitted. The table is configurable by the PC and is stored in the flash memory of the device.

LIN Master Slave
As a LIN Master/Slave, the device works as a stand-alone LIN bus arbiter with LIN-Slave function. Here a configurable schedule list is available, which is processed cyclically. In addition to the bus arbiter function, a transmit function is also available in this mode via a configurable transmit list.

LIN PC Interface
In addition to the stand-alone modes, the LIN-CAN Gateway can also be operated via the serial interface as a PC interface. Here, for example, the device can be operated as a LIN-Slave where the LIN objects on the PC are available for monitoring. The transmit table can be modified interactively. In addition, the LIN-Master function is available where the bus arbiter function can be triggered from the PC. With these functions, a PC-supported simulation of LIN-Slave or -Master devices is possible.

All modes can be configured via PC. The configuration values are stored in the FLASH Memory of the device and can be read out by the PC.

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.
