Modbus RTU through reliable wireless mesh
W-Modbus replaces the Modbus RTU cable with a reliable wireless mesh – it eliminates time-consuming installation planning, cabling, daisy-chaining and trouble-shooting. Plug-n-Play: No programming required. Enable energy savings and meet sustainability targets with wireless control.
The W-Modbus product acts as a proxy for a connected Modbus RTU device, effectively extending the bus and creating the possibility to make wired products wireless. A W-Modbus network consists of a single W-Modbus gateway with up to 100 W-Modbus Nodes.
Patented technologies
The W-Modbus product is built upon LumenRadio’s patented meshing technology MiraMesh - providing ultra-reliable device-to-device connectivity, easy installation, concurrent Bluetooth and extended range.
With LumenRadio’s W-Modbus solution it is possible to create a wireless Modbus RTU system that maintains the Modbus RTU standard, while still keeping a low latency.
INSTANT INSTALLATION
UNIQUE RELIABILITY
ECO-DESIGNED
LONG RANGE
- 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.
