IEC 60870-5 is a set of standards for telecontrol, teleprotection, and associated telecommunications for electric power systems, widely used in the European Union, the United Kingdom and other locations.
The crate provides a fully Rust-safe transport-agnostic implementation for IEC 60870-5 101/104 telegrams and common data types. The library contains almost the complete set of types and instruments required to easily write own client or server, including time conversion between Rust and IEC 60870-5 formats.
The crate IS NOT FREE for any commercial or production use. Please refer to https://github.com/roboplc/iec60870-5/blob/main/LICENSE.md for more information.
IEC 60870-5 Rust library is a part of the RoboPLC project.

// Convert the time tag to a timestamp

As IEC 60870-5 is a complex standard, 3rd party hardware/software vendors usually do not implement it it full, some functionality may require additional development/workarounds.
The library has been fully tested in pair with Beckhoff TwinCAT 3 TF6500 as well as with certain embedded implementations, used in the European Union power grids.
The most common problem is that the majority of the IEC 60870-5 104 servers require keep-alive frames. Such can be generated either using IEC 60870-5 104 S-Frames, or test U-frames out-of-the-box:
use iec60870_5::telegram104::Telegram104;
let telegram = Telegram104::new_test();
// Write the telegram to the target
