It can work as a message repeater to increase the network size, as well as connect different CAN networks with each other. When transmitting messages, it is irrelevant whether the CAN networks have different transmission rates or whether the messages are part of different higher-level protocols, such as. B. CANopen® and a proprietary protocol.
A flexibly adjustable filtering logic can accept freely selectable identifiers and implement them on the other network.
The CAN messages are forwarded to the other CAN network and sent out again according to the store-forward principle.
With the CAN bridge, the CAN networks are both physically decoupled (galvanic isolation) and the bus load on both CAN networks is reduced. The CAN bridge allows a flexible design of the network topology; star and tree structures as well as extensive line structures can be implemented. The CAN bridge can be configured for simple applications using the two rotary coding switches.
For more complex applications, the filtering and forwarding of CAN telegrams can be flexibly adjusted using the included CAN bridge parameterization software.
Up to 256 range filters and up to 4 bit filters are available for address filtering. The configuration is imported via a USB interface and can also be read out again.
The CAN bridge works in both 11-bit and 29-bit modes and can communicate with transfer rates of 10 Kbit/s up to 1 Mbit/s. It has a powerful microcontroller that can work even at the highest data rates and bus loads without loss of messages. 5 LEDs signal the status of the device and the connected CAN networks.
