Lead:
April 2025 – The Association of European Refrigeration Component Manufacturers (ASERCOM) has officially released the Modbus Electronic Data Sheets (EDS). This major advancement aims to standardize device communication and facilitate seamless integration across the refrigeration, air conditioning, and heat pump (RACHP) industry.

Marco Masini, President of ASERCOM, stated: “The introduction of Modbus EDS marks a significant milestone toward achieving seamless system integration and interoperability in our industry.” The EDS is compatible with Modbus RTU, ASCII, and TCP/IP, enabling consistent communication across different manufacturers and systems.
■ Simplified Integration with Unified JSON Format
Written in widely adopted JSON format, EDS files can be automatically processed, dramatically simplifying the integration of new devices into existing systems. This leads to significant reductions in development time and costs for manufacturers.
■ Flexibility and Future-Proof Design
EDS documents can be provided within the device itself, hosted on a central server, or included in system documentation. Importantly, they can be implemented without firmware updates for existing devices. Continuous updates ensure that EDS documents evolve alongside technical advancements.
■ Improved Reliability and Error Reduction
With detailed and standardized parameter and function descriptions, communication errors are minimized, boosting overall system stability and efficiency.
■ Facilitating IoT and Smart Building Integration
The EDS initiative supports the digital transformation of the RACHP sector by enabling better integration with smart buildings and smart grids, improving energy efficiency and operational effectiveness.
Matthias Kordon, who spearheaded the development, emphasized: “By making the EDS document freely available, we aim to accelerate adoption and establish a new de facto standard across the industry, making integration easier and enhancing interoperability.”
