Description (English):

This document specifies the communication interface, so that the transmitted parameters, signals and objects between a supply system (SS), with power converter/switch (PC/S) and high power interface – master control (HPI-MC) including the tractor implement management (TIM) server, and a consumer system (CS), with application (APP) and high power interface – control (HPI-C) including the TIM client and the task controller, can be used is in the agricultural industry. The mentioned signals are used during identification, initialization, operation, and shutdown modes of operation. This document does not cover the definitions of suspect parameter numbers (SPNs) for the signals, within the parameter group numbers (PGNs) for messages and the message setup. These definitions are given in ISO 11783 and SAE J1939. NOTE For information on messages (PGNs) see also Annex B.

Abstract

Overview

ISO 23316-6:2024 defines the communication signals for the electrical high‑power interface (HPI) used in modern agricultural and forestry machinery operating at 700 V DC / 480 V AC. It specifies how parameters, signals and objects are exchanged between a supply system (SS) - including the power converter/switch and HPI‑master control (HPI‑MC) with a TIM (Tractor‑Implement Management) server - and a consumer system (CS) - including application (APP) and HPI‑control (HPI‑C) with a TIM client and task controller. The document covers communication needed during identification, initialization, normal operation and shutdown.

Key topics and technical requirements

Communication process & system handshake: defined phases, preconditions and monitoring required to safely establish and maintain HPI connections.
System topologies: overview of AC and DC system topologies and how they affect communication.
Fieldbus‑based and IL‑based systems: identification, initialization and normal operation sequences for both fieldbus (e.g., ISOBUS) and isolation‑link (IL) implementations.
HPI interlock function: functional requirements and principles for interlock signalling to protect equipment and personnel.
Connection status & TIM interaction: requirements for HPI connection status monitoring and interaction with the TIM function state machine.
Insulation monitoring & isolation resistance: communication procedures for insulation monitoring (OIM) and minimum isolation resistance checks during initialization and online operation.
Diagnostics & annexes: includes normative communication signal listings (Annex A), ISOBUS message guidance (Annex B), topology examples, diagnostic trouble codes (DTCs) and insulation monitoring examples.

Note: ISO 23316‑6 does not define SPNs/PGNs or message parameter numbers - these are provided by ISO 11783 and SAE J1939.

Applications and who uses it

Tractor and implement manufacturers: design interoperable high‑power electrical interfaces and TIM implementations.
Power converter and HPI suppliers: ensure compatible signalling, handshake logic and interlocks.
System integrators and OEMs: implement safe startup/shutdown and communication sequences for electrified implements.
Testing labs & certification bodies: verify compliance with handshake, insulation monitoring and fieldbus sequences.
Standards and safety engineers: align electrical, mechanical and communication requirements across the ISO 23316 series.
