What is W-Modbus?

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 module 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.

A W-Modbus network consists of a single W-Modbus Gateway connected to the modbus master/client using a Modbus RTU cable and up to 100 W-Modbus Nodes, each of them connected to a modbus slave/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.
