SAE J1939 Blocks

The xPC Target J1939 blocks enable you to send and receive messages over a CAN network using the SAE J1939 message protocol. Before you start, provide a J1939 database in .dbc format.

Note the following:

• Use the FIFO mode of the Softing CAN hardware with these blocks.

The J1939 I/O - Using Transport Protocol demo illustrates the transmission and reception of J1939 data. It uses a loopback connection of two CAN ports in a single target PC. Note, the demo requires a J1939 database file, C:\work\J1939_demo.dbc, which the xPC Target software does not supply. You must provide your own database file, which must contain the requested information outlined in the demo.

This topic assumes familiarity with the SAE J1939 specifications.
