With LumenRadio's self-forming and self-healing wireless mesh technology MiraMesh, it is possible to create a wireless Modbus RTU network that maintains the standardization of the protocol. By converting the Modbus signals into MiraMesh we can send the Modbus RTU signal wirelessly with low latency. We call this W-Modbus.

Replacing wires with wireless communication brings significant benefits without changing the existing ecosystem. Wired devices such as sensors or actuators can easily convert to wireless, increasing flexibility and cost savings during installation and steady-state operation.

Features

• Out-of-the-box installation – just power up and connect to your Modbus device and you are up-and-running.

• Instant commissioning – 3 simple steps, commissioning the W-Modbus network in  minutes

• Mesh network – cover an entire building, utilizing the mesh network as your infrastructure.

• Range – 500 meters (line-of-sight) per hop in the mesh network

• Cognitive Coexistence – LumenRadio’s patented technology provides industrial-grade reliability and immunity to interference.

• Self-optimizing network – the mesh network will always find the best way to send messages through the network between devices.

• Modular configuration – you no longer need to have the same baud rate in the whole network, supports individual settings for each device.

System overview

A W-Modbus network consists of a single W-Modbus Gateway connected to the Modbus Client using a Modbus RTU cable and up to 100 W-Modbus Nodes, each of them connected to one Modbus Server over a Modbus RTU cable.

The W-Modbus network is built on LumenRadio’s MiraMesh, a self-forming and self-healing wireless mesh technology.

Description

W-Modbus eliminates the need to run control cable for Modbus RTU installations significantly reducing time-consuming cable installations, installation planning, troubleshooting, and daisy chaining. A  W-Modbus unit can be configured either as a Gateway that is connected to the Modbus Client or a Node that is connected to the Modbus Server. A W-Modbus network can consist of up to 100 Nodes.

The W-Modbus product is built with LumenRadio’s MiraOS and MiraMesh, consisting of several patented features enabling extremely reliable radio communication, fast installation, and extended range. MiraOS is used in a vast number of installations around the world for building automation, HVAC control, lighting control and industrial sensor networks.

W-Modbus utilizes the international license free ISM band at 2.4GHz.
