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.

CANblue II

Active Bluetooth interface/bridge
1 x CAN (High-Speed)

The CANblue II is a reasonably priced and versatile CAN Bluetooth module, which can be used in a wide range of applications due three supported operation modes. 

For service applications it enables e.g. the wireless access to CAN systems using the standard Bluetooth interface provided within many notebooks. Due to this, diagnostic data can be read or system configuration tasks can be performed very simple and flexible, even at components which are hard to reach.

Using several CANblue II devices network segments can be networked among each other. This enables the reliable connection of rotating or moving parts, e.g. in wind turbines, as well as the bridging of larger distances between different sub-systems up to 200 meters. Failure-prone slip ring connections or expensive installations of large CAN lines can such be avoided.

Not least, the Bluetooth-based communication also offers significant advantages in terms of range and noise immunity, compared to traditional WLAN solutions.

Bridge mode
The bridge mode allows the user to set-up a CAN-Bluetooth-CAN bridge by using two CANblue II devices. Message exchange occurs on layer 2 and is transparent. The device can also be used in systems with CANopen, DeviceNet or customer-specific protocols. CAN-ID filters can be set for data exchange via Bluetooth. Using more than 2 CANblue devices, multiple busses can be linked with each other.

ASCII/Binary protocol mode
In this mode, functions for transmitting and receiving CAN messages and for configuring the CANblue II are available to the user based on simple ASCII commands and optimized CAN binary messages. The CANblue II is ideal for "non-Windows" systems or embedded platforms.

PC operation mode with VCI driver support
Because it is supported by the VCI CAN driver, the CANblue II can be operated with all IXXAT tools and with customer-specified programs. In addition, wireless access to CAN systems via Bluetooth can also be easily achieved with existing VCI-based application programs and tools.

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.
