W-MODBUS – Wireless Modbus replaces a conventional RTU cable

Our new units with integrated W-Modbus technology provide the data points via radio. This means that there is no need for a conventional bus cable, while the Modbus RTU standard remains fully intact.
A wireless mesh topology is set up with the W-Modbus, offering maximum installation flexibility.
All units are connected to each other and thus help ensure that they cover an entire building.
The new W-Modbus technology creates a wireless Modbus RTU network that maintains the standardisation of the protocol and transmits the Modbus RTU signal wirelessly with low latency.
Patented functions enable extremely reliable and secure wireless communication, fast installation and extended ranges – even if a device in the mesh should fail.

Highlights:
• Wireless Modbus RTU architecture for smart HVAC and building automation
• Licence-free ISM band at 2.4 GHz
• Up to 100 units (nodes) in a shared mesh topology
• Signal transmission at low latency
• Long range up to 500 m (line of sight) by sending and forwarding data points (up to 8 hops)
• Ideal for refurbishment ⁄ retrofitting in the field and in rooms
• Reduced costs and time required for wiring (no data cable required), installation planning, troubleshooting
• Quick installation (push-in terminals) and easy mounting on in-wall flush box or on-wall
• Immediate commissioning in 3 steps (e.g. set address only, no further bus parameters necessary)
• Many standard languages for menu control (DE, EN, FR, ES, IT, RU, other available upon request)
