Return to Transport Protocol page
Description
The transport protocol block is similar to the Raptor CAN Definition block. This block will include the Raptor J1939 protocol stack in your model. This is necessary to facilitate all J1939 communication. The J1939 bus name defined in this block will be used in all other Raptor J1939 blocks to link the block to a specific J1939 bus. Multiple transport protocol blocks can be included on the model to facilitate J1939 communication on multiple CAN buses or on a single CAN bus with multiple addresses. The transport protocol block must be inside a periodically triggered subsystem. It is recommended that the block be inside a subsystem executing at the Foreground loop rate in order to best maintain the timings required for J1939.
