IEC 60870-5-101/104 C#/.NET

Source Code Library

This library provides support for the Companion Standard 101 (CS101) and 104 (CS104) of the IEC standard series for telecontrol applications (IEC 60870-5) and is commonly used in communication between a central station (controlling station) and an outstation (controlled station) in electrical power systems.

The C#/.NET source code library allows a fast and cost efficient implementation of the IEC 60870-5-101 and IEC 60870-5-104 protocols into .NET applications. The APIs are designed to be very easy to use and flexible. The library is written is compatible with .NET Framework 4, .NET 5, .NET standard 2.0, and Mono.
