DNP3 (Distributed Network Protocol) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies.

Usage in other industries is not common. It was developed for communications between various types of data acquisition and control equipment. It plays a crucial role in SCADA systems, where it is used by SCADA Master Stations (a.k.a. Control Centers), Remote Terminal Units (RTUs), and Intelligent Electronic Devices (IEDs). <>

It is primarily used for communications between a master station and RTUs or IEDs.

DNP3 Demo Win DLL includes simple (Server and Client C programs )example using a Command window and command line inputs.

The source code will allow you to quickly compile your own examples with the features of your existing development environment to work with our DNP3 DLL.

FreyrSCADA DNP3Windows SDK contains Win DLL (precompiled library), Static link lib, Demo Server and Client programs, Visual Studio Demo console project files, Doxygen .

We used Visual studio compiler to create the dll, sample test projects.
