ISOAgLib SE
The TÜV-certified ISOBUS software stack for agricultural ECUs.
A future-proof foundation for building AEF-certified ISOBUS solutions that run reliably across platforms. Develop faster, safer, and hardware-independent implement applications with confidence.
Your reliable foundation for ISOBUS development
ISOAgLib SE accelerates your ISOBUS system development with a modular, production-ready API and practical tutorials that make complex standards easier to handle. The library runs on virtually any hardware platform, ensuring smooth integration while meeting all requirements of ISO 11783, ISO 25119-SRL 2 and AEF certification. This combination enables faster time-to-market, reliable interoperability, and proven safety certification.
Key benefits of ISOAgLib SE ISOBUS library
Flexible Hardware Use – No Vendor Lock-In
Our ISOBUS library runs on any C-compiler platform. By breaking ISO 11783 into clear modules, ISOAgLib SE makes development easier to understand, integrate, and maintain – with full flexibility across hardware.
Modular Approach, Faster Launch
Each ISOBUS function comes as a clear module, easy to extend or plug into existing systems. Without needing deep ISOBUS or CAN expertise, your developers can move from concept to implementation much faster.
High Learning Curve, Less Complexity
Developers work with intuitive high-level commands instead of low-level ISOBUS details. This speeds up onboarding, simplifies validation, and keeps the library reliable across hardware platforms.
Quick Onboarding with Real Examples
Tutorials like "First Steps" and the "System Validation Test" guide your developers from zero to working prototypes, demonstrating core functions and ensuring setups are certification-ready.
Proven Interoperability
The library supports all major AEF functions — UT, AUX-N/O, Task Controller, File Server, TECU, TIM, and more — validated through official AEF Conformance Testing for reliable performance in mixed-vendor environments.
Trust through Compliance
ISOAgLib SE is ISO 25119 (SRL 2) certified and TÜV Süd re-certified annually, ready for safety-critical applications while reducing compliance effort and ensuring long-term trust.
Optimized Performance for Your Hardware
The library is delivered prebuilt for your target system, ensuring best possible performance while minimizing integration effort. You save development time and avoid configuration headaches.
Seamless Embedded Integration
Developed in plain C, ISOAgLib SE runs on almost any embedded system. Its lean, portable design integrates seamlessly into existing ECU platforms without extra adaptation layers.
What you get with ISOAgLib SE ISOBUS library
System Validation Test Application
Every hardware can be validated with the included System Validation Test. This reference implementation covers all API functions, ensures that integration with customer hardware works as expected, and provides a reliable preparation for AEF Conformance Testing.
Full Support for AEF Functionalities
From Universal Terminal (UT) and Auxiliary Controls (AUX-N/O) to advanced Task Controller functions (TC-BAS, TC-GEO, TC-SC, LOG), File Server, TECU, ISOBUS Shortcut Button, and TIM — ISOAgLib SE covers all relevant AEF-certified features. This breadth of support future-proofs your applications and guarantees interoperability.
Standardized Virtual Terminal (ISO 11783-6)
The library provides everything needed to build a compliant Virtual Terminal client. This makes it easy to design standardized operator interfaces that ensure a consistent user experience across different machines and displays.
Task Controller (ISO 11783-10)
Task Controller support enables core precision farming functions such as data logging, map-based control, and section management. With ISOAgLib SE, developers can integrate farm management features that increase efficiency and accuracy in the field.
File Server (ISO 11783-13)
The file server facilitates structured file handling and reliable data exchange between machines and systems. It ensures secure storage and smooth transfer of task data, maps, and log files, supporting consistent workflows and interoperability within ISOBUS environments.
Tractor ECU and TIM Modules
Beyond implement-side functions, ISOAgLib SE extends ISOBUS communication to tractor-side applications. TECU and TIM server/client modules allow seamless interaction with tractor ECUs and automation of machine workflows, supporting next-generation smart farming.
Comprehensive ISOBUS Communication Modules
ISOAgLib SE provides support for integration of communication stacks such as J1939, UDS, and proprietary messaging. This ensures smooth data exchange between agricultural ECUs and implements, enabling stable system behavior across different machine types and vendors.
