Modbus Workbench
Modbus Workbench is for configuring, testing, and analyzing Modbus devices in a structured and repeatable way.
It helps engineers build workspaces, manage connections, define register maps, and monitor live data through a clean, predictable workflow. The tool supports commissioning, troubleshooting, and validation of Modbus-based systems across TCP and Serial (RTU) networks, keeping everything local and offline-first for field reliability.
Community-driven tools with transparent release notes and public source code.

Highlights
Multi-workspace project management
Organize isolated Modbus projects with persisted configuration, search, and quick switching.
Serial (RTU) & TCP connections
Configure COM/baud/parity or host/port endpoints and validate with one-click connection testing.
Slave & register operations
Manage slaves by Unit ID and read, write, poll, or scan standard Modbus register types (0x01–0x10, 0x16).
Flexible data decoding
Handle 16/32/64-bit integers and floats with custom byte order, scale, offset, decimals, clamps, and bit extraction.
Live analyzer dashboard
Build value tiles and trend charts for any decoded signal at configurable poll intervals.
Traffic monitor & scoped logs
Inspect every request and response in real time with filtering, export, per-workspace log levels, and retention control.
Local, offline-first operation
Runs entirely on your machine with no cloud dependency, ideal for secure and field environments.
Cross-platform support
Available for Windows and Linux, with macOS support coming soon.
