DNP3
DNP3 (aka IEEE 1815) is the most common SCADA protocol used in electric power in North America. It is event-based and efficiently transfers measurement data between outstation and master components. It can be operated in a purely poll-based mode, or an unsolicited (push) mode where the outstation transmits events as they occur.

Scale Up or Down
Our DNP3 library is fully asynchronous and uses the most efficient event-driven backend provided by your OS: epoll on Linux, IOCP on Windows, etc. The library scales to many thousands of concurrent communication sessions while maintaining a small memory and CPU footprint.
Conformance Testing
The outstation is tested using a fully-automated conformance test harness. The test harness implements the conformance test procedures as published by the DNP Users Group and augments our own unit and integration test suites. This means that users are unlikely to face interoperability challenges talking to 3rd party implementations of the protocol.
