Python SLMP client for Mitsubishi FREQROL‑E800 inverters
This library implements the SLMP protocol to communicate with Mitsubishi Electric FREQROL‑E800 series inverters over TCP or UDP. It parses Mitsubishi’s address syntax (X/Y hex, W decimal) and exposes simple read/write methods, plus range access and remote control commands. It’s aimed at plant automation engineers and hobbyists who need to program or monitor inverters without writing low‑level protocol code, offering a lightweight, pure‑Python alternative to commercial SDKs.
