Block RITM-CANFD RX accepts classic CAN frames and CAN FD frames via a single CAN FD socket. Field ProtocolMode The output bus shows the format of the actually received frame. If there is no message at the current step, the block sets the zero values of the output bus fields and returns 0 the output is Amount.
Message Filter
The filter is applied in the operating system before sending the message to the model. The message is accepted if the condition is met:
CAN_ID & Mask == Filter_ID & Mask
The zero bit in Mask excludes the corresponding bit of the identifier from verification, a single bit requires matching with Filter ID. To receive all messages, set 0 for the parameters Filter ID: and Mask:.
