CANbridge
 

-Configurable CAN/CAN Gateway

The CANbridge allows the coupling of two CAN networks even with different bit rates. Unlike a CAN-Repeater, which only translates the electric signals, the CAN messages are received completely by the CANbridge and then sent to the other CAN network under consideration of filter and conversion rules (Store-Foward principle). The message filters can be defined here for individual CAN identifiers via filter masks. With the aid of conversion rules, CAN messages can be forwarded under another identifier. With these mechanisms, the bus load can be reduced in the individual networks by only sending those messages to the other network that are of interest.

With the appropriate software, the CANbridge can also be used for coupling CAN networks with different higher layer protocols such as CANopen and DeviceNet.

The CANbridge has a powerful 16-bit microcontroller that can also process bursts at higher data rates without message loss. LEDs signalize the current status of the coupled networks.

The CANbridge is configured via serial interface with a convenient Windows program. The configuration of the CAN-interfaces, setting of the operating modes and the filter- and coversion tables are saved on the bridge.

The additionally available Board-Support-Package provides the most important interface functions and enables users quickly create their own applications. These can then be loaded into the flash memory of the CANbridge via the intern serial interface. Corresponding protocol stacks are also available for the development of CANopen or DeviceNet applications.

The CANbridge is available in the three different versions: as an industrial version in a top hat rail housing or in a robust mental housing and as an automotive version in a robust mental housing.
