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.

CAN@net II/Generic

CAN-Ethernet gateway and
CAN-Ethernet-CAN bridge

The CAN@net II/Generic enables easy and flexible access to
CAN systems via Ethernet. The device provides two operation
modes, a bridge mode and a gateway mode.

This product is not recommended for new developments. For new developments we recommend to use the successor product Ixxat CAN@net NT 200/420.

How it works

CAN-Ethernet Gateway
In the gateway mode the CAN@net II/Generic is connected to a PC or to a controller platform via TCP/IP. The application program on the host communicates via a standard TCP/IP socket and uses a simple ASCII protocol. As CAN-Ethernet Gateway, the CAN@net II/Generic offers simple, flexible access to CAN systems via a LAN or via the Internet.

 CAN-Ethernet Gateway operation mode



CAN-Ethernet-CAN Bridge
Using two CAN@net II/Generic, a CAN-Ethernet-CAN bridge can be implemented. This bridge allows the exchange of CAN messages between two CAN systems via TCP/IP where filter tables can be defined.

 CAN-Ethernet-CAN Bridge operation mode

Configuration

The configuration of the TCP/IP parameters can be performed using a PC tool with automatic device detection. The configuration of the bridge functionality and the CAN communication is supported by an implemented web-server.

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.
