SAE J1939-75-2026 Application Layer - Generator Sets and Industrial

A cancelled SAE recommended practice defining application-layer data parameters and messages for monitoring and controlling generator sets and industrial equipment.

SAE J1939-75 MAR2026 defines application-layer data parameters (SPs) and parameter groups (PGs) used to monitor and control generators, driven equipment, utility connections, and electrical buses in power-generation and industrial applications. The document covers generator, utility, bus, and synchronization parameters within SAE J1939 communications networks. This edition was cancelled in March 2026 because its technical content was moved to SAE J1939DA, which should be consulted for current parameter and message definitions. The standard references SAE J1939, SAE J1939DA, and SAE J1939-71, and applies to generator sets, engines, turbines, industrial equipment, and related stationary or vehicle-derived systems using SAE J1939 communications.

Application Scope: Electric power generation, generator sets, industrial equipment, utility interfaces, parallel generator systems, heavy-duty vehicle-derived components, and SAE J1939 network implementations.
