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.

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.

TCP Simulator (Modbus server)

Turn the app into a Modbus TCP server across all four register banks and multiple Unit IDs, with fixed values, generators, and automation rules — or route a real slave to act as a software gateway.

Virtual Devices

Build reusable device blueprints once and drop them into any workspace's simulator; clone the built-in catalog, save from a live device, and export/import as JSON to share.

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.
