Modbus TCP to MQTT IoT Gateway

The Modbus TCP to MQTT IoT Gateway is a device that enables the communication between Modbus TCP devices and MQTT (Message Queuing Telemetry Transport) servers in the context of the Internet of Things (IoT).

Modbus TCP is a widely used communication protocol in industrial automation for exchanging data between devices, while MQTT is a lightweight messaging protocol commonly used for IoT applications to facilitate communication between devices and servers.

The Gateway acts as a bridge between Modbus TCP devices, such as PLCs (Programmable Logic Controllers) and sensors, and MQTT servers, allowing for seamless integration and data exchange between the two protocols. This enables Modbus TCP devices to send data to MQTT servers for further processing or analysis, and vice versa.

This bridge allows for:

Remote monitoring & control
Universal data exchange
Improved data visibility

This gateway is a valuable tool for various industrial applications like automation, security monitoring, and remote data acquisition.
