Description

The "DM25 Definition" script is required to follow the template outlined in the "motohawk_saej1939_dm25tx_example" example file.

The definition script specifies a constant value, a port value, or an external datastore for each input parameter. The location of the block in the application will determine when the port-related information is updated.

The definition script must add a link to an Expanded Freeze Frame Collection Definition. The Collection specifies the data content in the Expanded Freeze Frame and the order of the Freeze Frame Instances that will be transmitted if they contain data.

The block adds a link to the SPN, FMI, and Occurrence Count data as an OBD Fault Manager Custom Field. The FMI and Occurrence Count are optional. If not specified, the blockset will always return a "31" for the FMI and "127" for the Occurrence Count.
