J1939 protocol

The SAE J1939 protocol is widely used in industries that rely on engine- and equipment-based communications, including heavy-duty and utility vehicles, agriculture and forestry machinery, marine systems, military applications, and energy production equipment.

Built on the CAN ISO 11898-1/2 standard as lower layers, J1939 enables Electronic Control Units (ECUs) within a network to communicate through standardized messages, ensuring interoperability and reliable data exchange.

ISIT J1939 protocol Stack

The ISIT J1939 stack is available in both single-channel and multi-channel CAN versions, supporting the implementation of multiple Application Controllers (ACs) on a single ECU.

Thanks to its modular architecture, the stack can be tailored to specific requirements in terms of CPU, memory, number of messages (PGNs), CAN networks, and additional supported protocols. It also integrates seamlessly with extended protocols such as:
  • Transport Protocols (ISO-TP)
  • Diagnostics (DiagOnCAN, UDS)
  • Proprietary extensions
The stack manages key J1939 functions such as Address Claiming, NAME management, command messages, and transport protocols (BAM, P2P). It supports both event-driven and periodic PGNs for transmission and reception, ensuring flexibility across diverse applications.
