Modbus RTU Display Control Panel

This project provides a graphical user interface (GUI) for interacting with a Modbus RTU device using the Tkinter library in Python. The application allows users to connect to a Modbus device via a serial port, configure communication parameters, send data to holding registers, control a buzzer, and monitor the status of various keys and LEDs.

Features

• Connect/Disconnect to Modbus Device: Connect or disconnect to a Modbus RTU device via a selected serial port and baud rate.
• Send Data to Holding Registers: Send up to three lines of text to the device's holding registers.
• Buzzer Control: Turn the buzzer on, off, or make it beep.
• LED Status Monitoring: Monitor the status of three LEDs which represent the state of UP, DOWN, and ENTER keys.
• ACK Keys: Acknowledge the pressing of UP, DOWN, and ENTER keys.
• Modbus Configuration: Change the Modbus device's communication parameters including baud rate and Modbus ID.

Requirements

• Python 3.x

Installation

1. Clone the repository:

   git clone https://github.com/aliyaghoobi88/Modbus-Display-Config-Python.git
   cd Modbus-Display-Config-Python

2. Install the required Python packages using requirements.txt:

   pip install -r requirements.txt

Usage

1. Run the application:

   python modbus_gui.py

2. Connect to Modbus Device:

   • Select the appropriate serial port and baud rate from the dropdown menus.
   • Enter the Modbus ID.
   • Click on the Connect button.

3. Send Data to Holding Registers:

   • Enter text in the Line1, Line2, and Line3 fields (up to 11 characters each).
   • Click the Send to Holding Registers button.

4. Control the Buzzer:

   • Use the Buzzer ON, Buzzer OFF, and Beep buttons to control the buzzer.

5. Monitor and Acknowledge Keys:

   • The LED indicators will show the status of the UP, DOWN, and ENTER keys (green for pressed, red for not pressed).
   • Click the ACK buttons to acknowledge key presses.

6. Change Modbus Configuration:

   • Select a new baud rate and Modbus ID.
   • Click the Change Param button to apply the new configuration.

GUI Layout

• Top Section: Connect/Disconnect controls.
• Middle Section: Text input for Line1, Line2, Line3 and sending to holding registers.
• Lower Section: Buzzer controls, LED indicators, and ACK buttons.
• Bottom Section: Modbus configuration controls.
