Discover Modbus Viewer — a powerful and easy-to-use application designed for engineers, technicians, and enthusiasts working with the Modbus protocol.

Key Features:

Universal Support: Works with Modbus TCP (via Wi-Fi/Ethernet), Modbus RTU (via RS-485, USB, and Bluetooth SPP adapters), and supports Modbus RTU over TCP.

Automatic Device Discovery: A smart network scanner automatically detects active Modbus devices over TCP, RTU, and Bluetooth interfaces, eliminating the need to manually enter IP addresses and Slave IDs.

Intuitive Interface: Create and save project configurations for quick and convenient access.

Real-Time Monitoring: View register and bit values in real time with data logging capabilities.

Advanced Trends & Export: Enable graphical data visualization with a fully interactive time scale (tap or drag for quick navigation). Features include a Trend Calendar for fast date selection, chart synchronization for precise comparison, and adjustable chart density settings. Export all trend and log data to CSV files.

Complete Control: Read and write Holding Registers, Input Registers, Coils, and Discrete Inputs.

Data Processing: Supports 32-bit and 64-bit values, Signed formats, Float types, and Multiplier settings. Engineering units are now an integral part of register attributes.

Display Formats: View values in DEC, HEX, and BIN formats.

Customizable Parameters: Adjust polling intervals, timeouts, and other connection settings.

Built-in MQTT Ecosystem:
A comprehensive toolkit for remote control and telemetry:
Terminal: Direct broker interaction for advanced testing;
Explorer: Real-time monitoring of all topics and data streams;
Dashboards: Customizable visual panels for data visualization and control;
Home Assistant Integration: Full MQTT Discovery support.

Built-in HMI Dashboard:
Visualize your data using convenient and functional information tiles:
* Create personalized dashboards for quick monitoring of key parameters;
* Full customization for each tile: define custom variable names, engineering units, and rounding rules;
* Flexible interface adaptation: choose the number of tiles per row and adjust text size for optimal display on any device.

Built-in Modbus RTU Sniffer & Detailed Inspector:
Perform professional network diagnostics and device configuration recovery at a level previously available only on desktop systems.

Capture and analyze communication between Master and Slave devices in real time. Use the powerful analysis engine not only with live traffic but also with previously saved session logs (Sniffer/Client), enabling detailed retrospective analysis and detection of intermittent issues.

Intelligent Configuration Wizard: Export analyzed data directly from logs into Client or Server settings. This allows you to create a working device profile with a single click, transforming real network traffic into a ready-to-use control configuration.

Detailed HEX Log Inspector: Instantly decode every packet. The application automatically converts raw HEX data into a structured table containing register addresses and their actual values.

Built-in Modbus Server TCP:
The application includes a powerful Modbus Server TCP with configurable registers and register attributes. Various data representations are supported, including Hex, Bin, 32/64-bit values, and Float formats.

Technical Compatibility:
Optimized for PLC, SCADA, and HMI systems. Supports various USB adapters (USB-RS485/Serial) and converters for direct Modbus RTU connectivity.
