Modbus Master

Modbus Master is a super handy tool built on Qt that acts like a Modbus master application. It helps you chat with both Modbus RTU and TCP slaves, letting you keep an eye on all the traffic going through Modbus.

Easy to Use and Portable

This tool comes in a neat, portable package. You can just run it by opening the EXE file—no need for any special installations! Plus, it doesn’t leave any traces behind in your Windows registry or other system settings, which means you can use it without needing admin rights.

Simple Uninstall Process

If you ever want to get rid of it, just delete the files you downloaded from the internet. You can also pop it onto a USB flash drive or any other device with ease!

User-Friendly Interface

The layout of Modbus Master is really intuitive! You can easily see how many packets are being sent and if there are any errors. The main screen has smart buttons that let you quickly access features like scan, read/write, connect, or reset counters.

Monitoring Made Easy

You can start or stop the Modbus monitor with a click. If things get messy, clear everything out in one go! Want to check out RAW data? No problem! You can even save your data as a plain text file.

Customizable Settings

Modbus Master lets you pick your serial port settings including baud rate, data bits, stop bits, parity, and RTS. For Modbus TCP setups, just enter the slave IP and TCP port details.
