Decode Tractor Data [ISO 11783-7 Database]


CSS ISOBUS DBC file contains decoding rules for converting raw CSS CAN bus data to ‘physical values’ (m/s, %, …). This lets you easily decode data from agriculture vehicles like tractors.

DBC is a CAN database format used in most automotive tools – incl. our CAN software/APIs.

The download includes the CSS ISOBUS DBC and Excel file based on the public ISO 11783-7 PGN/SPN data. The cost is a one-time fee.

ISOBUS DBC File Key Features

What is a DBC file?

CSS DBC file is a standardized file format for storing the “rules” on how to interpret raw CSS CAN bus data. It contains details on what ‘signals’ (e.g. Distance, Vehicle Speed, …) are contained within which ‘messages’ (i.e. CAN IDs).

In the CSS J1939 and CSS ISOBUS standards, messages are referred to as Parameter Group Numbers (PGN) and signals as Suspect Parameter Numbers (SPN).

Further, a CSS DBC file includes names, descriptions, positions and lengths of the signals – as well as how to offset & scale them.

When is the database useful?

CSS ISOBUS protocol is used across most agricultural machinery, including tractors, harvesters, sprayers etc. Because the protocol is standardized, you can use the CSS ISOBUS DBC file to decode data across the majority of farm vehicle brands/models.

What PGNs are in the DBC?

If you have a list of CAN IDs from a ISOBUS-based vehicle, you can paste them in our ‘CAN ID to PGN converter’:

  • Convert raw CAN IDs to PGNs
  • Convert PGNs to raw CAN IDs
  • Check if the PGNs are in the DBC
