Zero Data Loss

Ensure caching the data closer to the Edge preserves data against network failure.

Two Way communication

Agate Modbus MQTT Bridge that allows MQTT manager application to collect & manage Modbus slaves.

Flexible Configuration

You can configure and group the data as multiple MQTT Topics and JSON-based key-value data formats.


Protocol specification

The Modbus gateway adeptly supports communication via two transmission modes: RTU or TCP. Modbus offers high operational flexibility. The technical deployment of the Modbus gateway is notably simple. This distinction arises because the two transmission modes operate within a master-slave architecture.


MQTT Broker Connectivity

The Modbus gateway functions as a master. It establishes direct connections to slaves (devices) through Ethernet or serial interfaces. Bevywise MQTT Broker provides MQTT access to Modbus data. Configuring a Modbus gateway, as well as reading & writing to them via MQTT indicates the connection of the MQTT broker. Speakable devices connected to the Modbus gateway communicate using the Modbus protocol. They transmit data through the MQTT broker. This data is then visualized using Agate.

compatible devices

Modbus compatible devices

In everyday applications, most Modbus implementations involve devices supporting the Modbus protocol. These devices typically handle modest amounts of data communication. Energy Meters, Industrial Machine PLCs, HMI hardware, I/O interfaces and modules, sensors, modems, device controllers, network gateways, network host adapters, AC/DC inverters, SCADA hardware, software device drivers, smart home devices, routers are the most widely used and adopted devices that communicate via Modbus gateway with the MQTT broker. You can use any of the mentioned devices with the Modbus Gateway for a wide range of applications.

Configurable User Interface

Modbus Gateway, Agate comprises a configurable user interface. Users can configure the data location on Modbus slaves. They can assign keys to interpret the data conveniently within the browser window. Users can also configure the monitored query interval based on the intensity of the process/machines.


Compatible with any Platform

The gateway is set up to extract data from machines. And converts the data into MQTT, and then sends it to the Bevywise MQTT Broker. Via MQTT communication, the Modbus MQTT Gateway is compatible with any IoT server. It includes IBM Watson, Azure IoT, AWS IoT, Google Cloud IoT, and Bevywise IoT Platform.

Secure Communication

Secure Communication

A secure way of collecting & transferring data is essential for industries to attain efficiency. TLS/SSL protocols enable encrypted communication between the Gateway and IoT servers. This ensures a secure and safe data transfer. Also, the device level auth makes a secure connection between Modbus Gateway & MQTT Broker.

Run it where you want

Available as a software package that can run on the Linux Operating System or as a hardware bundle. Depending on your requirements, you will be able to set up the MQTT Broker with the agate at your own premises based on your requirements.

What is Modbus Gateway?

The Modbus gateway serves as a vital intermediary that connects different Modbus protocols within industrial systems. It facilitates seamless communication among devices or networks. This involves devices operating on different Modbus standards or versions. It ensures interoperability and smooth interaction among them. These gateways have a pivotal role in unifying diverse Modbus-based devices. They enable effective communication despite differences in protocol variations or specifications. These gateways enhance connectivity by translating and mediating data between dissimilar Modbus networks. This streamlines operations within industrial environments.

The Modbus gateway acts as a translator. It allows devices using different Modbus standards to comprehend & communicate with each other. It acts as a mediator, ensuring the smooth flow of data. This occurs across different Modbus devices or networks, fostering efficient communication & integration within industrial setups.

Modbus Gateway Applications


Modbus Gateway Applications

The Modbus gateway supports the widely used Modbus protocol. It facilitates communication in workflow and production unit automation. This protocol transmits information between electronic devices in the real world. These devices connect through buses/networks or continuous streamlines over Ethernet.

Modbus gateway is extensively used in the industrial manufacturing sector by users & manufacturers. The common use case involves communication between a human-machine interface (HMI), supervisory control & data acquisition ( SCADA) system, & sensors, PLCs, or PACs. This enables interoperability among diverse automation equipment in a cost-effective manner.
