In the field of industrial IoT and industrial control, it is inevitable to deal with Modbus devices, and debugging and managing these devices can often be complex and frustrating. OpenModScan, an open-source and free tool, addresses this pain point! If you need to quickly debug Modbus devices and easily parse data, this tool is your best choice.
What is OpenModScan
OpenModScan is a powerful and easy-to-use tool that can quickly connect to and manage devices that support the Modbus protocol. It supports two main transmission modes (TCP and RTU), allowing you to read and write data, as well as scan and parse device communication logs. Whether it’s data reading and writing or locating device issues, OpenModScan is like a Swiss Army knife for industrial IoT, helping you get started easily.
Core Features:
1. Modbus Data Read and Write Control
- Supports reading coil and discrete input status, function codes 0x01 and 0x02.
- Easily write single or multiple coils, function codes 0x05 and 0x0F.
- Efficiently operate holding registers and input registers, function codes 0x03 and 0x04.
2. Powerful Device Scanning Functionality
- Automatically scan Modbus addresses to quickly discover devices.
- Supports both Modbus-TCP and Modbus-RTU protocols, covering all application scenarios.
3. Communication Log and Message Parsing
- Records Modbus communication logs for easy problem localization.
- Includes a built-in message parser to help you understand complex device data.
4. Cross-Platform Support
- Compatible with Windows and various Linux systems (such as Ubuntu and Fedora). No system restrictions, just start using it.
