The send cycle times, send types and signal positions within mes-sages – all defined in the communication database – may differ To exchange data between different networks, a gateway ECU is needed that only transports to the other network those messages or signals that are actually needed. between the source and target networks. The values of the signals to be transmitted are not changed in the process. In case of an Rx timeout, the CANbedded Gateway implements a substitute value strategy. The signal to be transmitted is written and routed with a predefined signal value (default value or special substitute value). If routing relationships occur that cannot be resolved, e. g. if the signals of a routing relationship have different sizes, the application can use C callback functions to flexibly adapt sig-nal 3/12 Application Areas CANbedded Gateway is a mature standard software component for gateway ECUs between different CAN or LIN networks. CANbedded Gateway lets users define routing relationships simply and quick-ly. Both 1:1 and 1:N routings are supported in any direction. The CANbedded Gateway utilizes bus-specific standard components of CANbedded, and so it is hardware independent. It covers the spe-cific contents before routing (e. g. by scaling signal values). Message Routing In routing of messages, the entire message is routed in either the interrupt or task context. This routing type is faster and more efficient than signal routing, but it cannot be applied in all rout-ing requirements of many different OEMs. Functions The CANbedded Gateway contains complex mechanisms for receiv-ing all messages and signals and then sending them to another relationships. In message routing, the messages may differ in network under consideration of filter and conversion rules. Users can select from: their message-ID, send cycle and send type.
