Modbus-TRU

About the Testbed

Modbus RTU is a serial communication protocol widely used in industrial and automation systems for connecting devices such as sensors, actuators, and controllers. It operates on a master-slave architecture and uses a compact, efficient binary communication format over serial communication standards such as RS-485 or RS-232.

Industry Applications 

In this testbed setup, multiple sensors are connected to a shared Modbus RTU communication bus, enabling them to communicate with a central controller or master device. The purpose of this testbed is as following:

• Sensor Testing: It provides an environment to evaluate the performance and compatibility of newly developed Modbus RTU sensors. These sensors are tested to ensure they adhere to the Modbus protocol, handle data efficiently, and operate reliably under various conditions.
• Gateway Evaluation: The testbed also includes gateways designed to bridge Modbus RTU with other communication technologies or protocols, such as Modbus TCP/IP, MQTT, or other Internet of Things (IoT) standards. Testing focuses on ensuring seamless data translation, maintaining data integrity, and achieving interoperability between Modbus RTU devices and systems using different communication protocols.

This setup simulates real-world industrial scenarios, making it ideal for validating both hardware and software aspects of Modbus RTU devices and gateways, ensuring robust and interoperable communication solutions for industrial and IoT applications.
