What is Modbus Master?

Modbus Master

Modbus Master is a super handy, lightweight tool built with Qt that lets you easily communicate with Modbus RTU and TCP slaves. It's perfect for monitoring and examining all the traffic on the Modbus network.

Easy to Use and Portable

This tool comes in a neat portable package. You can just open the EXE file on your system without any fuss! The best part? It won’t leave any traces in your Windows registry or other config data, so you don’t need admin rights to run it.

Monitor Like a Pro

You can start or stop the Modbus monitor whenever you want. With one click, clear your entire working space if things get messy. It also lets you view RAW and PDU data and save all that info as a plain text file.

Customizable Settings

Modbus Master gives you control over your setup by allowing you to choose the serial port, baud rate, data bits, stop bits, parity, and RTS settings. For Modbus TCP setups, just specify the slave IP address and TCP port!

Tweak Your Monitoring Experience

You can set how many lines you'd like to use for monitoring data and even adjust the response timeout (in seconds). Plus, it offers options like selecting Modbus mode, slave ID, scan rate, start address, number of coils, format code—all customizable based on your needs.
