CAN network bridge
Helmholz

CAN bus systems have become widely distributed in automation technology and are also being used more and more frequently in complex applications.
The CAN Bridge from Systeme Helmholz GmbH enables the coupling of two CAN networks of the same or different types.
Thereby, the CAN Bridge can operate both as message repeater for increasing the network expansion as well as connecting different CAN networks with each other. It is not significant thereby whether the CAN networks have different baud rates or operate with different protocols, e.g. CANopen® and a proprietary protocol.
A flexible, configurable filtering logic can adopt freely selectable identifiers and implement on the other network. The CAN messages are forwarded to the respective other network according to the Store-Forward principle and sent out again.
Using the CAN Bridge, the CAN networks are both physically decoupled (electrical isolation) as well as reducing the bus load on both CAN networks. The CAN Bridge enables a flexible design of the network topology; star and tree structures can also be implemented as expanded line structures.
The CAN Bridge can be configured for simple applications using the two rotary encoding switches. In the case of more complex applications, the filtering and forwarding of the CAN telegrams can be flexibly adjusted using the supplied CAN Bridge configuration software. Up to 256 range filters and up to 4 bit filters for address filtering are available. The configuration is read in using a USB port and can also be read out again.
