DNP3 (Distributed Network Protocol) is one of the leading standards for communication between control centers (SCADA systems) and intelligent electronic devices (IEDs) in substations. It is also widely adopted in hydropower, gas distribution, and other critical infrastructure sectors.

JPEmbedded’s DNP3 library delivers a flexible, lightweight, and platform-independent solution that simplifies integration and ensures reliable data exchange across diverse systems. Designed with embedded applications in mind, it supports both master and outstation roles and works seamlessly over serial and TCP/IP connections — with or without an operating system.

Developed in C++ for optimal performance, the library combines efficiency, security, and easy customization, offering:

• Level 4 interoperability
• Support for static data and event classes (0–3)
• Read/write operations and control commands
• Data freeze functionality
• Cybersecurity compliance with

With its modular design and proven reliability, JPEmbedded’s DNP3 library provides a future-ready communication stack for next-generation automation and energy systems.
