The IEC 60870-5-104 standard, introduced by the IEC in 2000, enables reliable communication between control stations and substations over TCP/IP networks, building on the IEC 60870-5-101 application layer and using a client-server model.

JPEmbedded’s 104 library provides server and client-side functionality and is implemented in C++ for seamless integration across a wide range of hardware platforms, with or without an operating system. Its highly configurable architecture allows developers to include only the required subset of ASDUs, minimizing the executable size and optimizing resource usage.

This flexible, lightweight library is ideal for embedded and industrial applications, enabling rapid development of smart grid solutions with robust, standards-compliant communication. 

The Library implements the latest IEC 62351 cybersecurity recommendations (2025).
