MTUI

MTUI is an extensive Modbus client that runs in pretty much any terminal, written in pure safe Rust on top of tokio-modbus and ratatui.

Features:

• Modbus TCP and RTU, plus a built-in mock device for experimenting
• Live register reading with auto-refresh, pause/resume and slave-id selection
• Interpretation columns with configurable word order: u16, i16, hex, binary, ASCII, u32, i32, f32, f64, M10K and more
• Panels: main view, pinned, labeled, custom rules and an address matrix
• Pin, label and custom-rule registers; jump to an address or label
• Value graph for a register over time
• Register writes, with a write log and an optional read-only mode
• HTTP API (POST /read, POST /write, GET /health), runnable standalone with --headless
• Dump read data to a file and copy addresses to the clipboard
• Configurable via config.json (or --config <path>) and an in-app settings screen

Press "h" inside the app for all available keybinds.

Modbus RTU (serial) and the clipboard rely on interfaces that snapd does not auto-connect. After installing, run:

 snap connect mtui:serial-port
 snap connect mtui:raw-usb
