W-Modbus - Wireless Modbus replaces conventional RTU cable

Back to blog

  • W-MODBUS is a radio-based further development of the proven Modbus standard. Handled products can be easily replaced by wireless devices within the wireless modbus RTU network. The standardized Modbus protocol is preserved, the signals are transmitted with low latency.

  • W-MODBUS makes it easier to set up intelligent building automation thanks to reliable and safe wireless communication. The new technology scores through cost savings, increasing flexibility and falling installation and maintenance effort. Thanks to the mesh topology, up to 100 devices can be assigned to a W modbus gateway.

W modbus highlights

  • Wireless RTU architecture

    For intelligent HVAC and building automation

  • Lowers costs and time

    For wiring, installation planning, troubleshooting

  • High range

    Up to 500 m by sending and forwarding data points

  • Fast installation

    Thanks to simple assembly and immediate commissioning

  • 100 devices in a mesh

    Extensive mesh topology with up to 100 devices

  • Ideal for retrofitting

    For simple and quick renovation / retrofitting

  • Low latency

    The signals are transferred reliably, with low latency

  • Many standard languages

    For menu renewal (de, en, FR, ES, IT, RU, more on request)

  • Royalty

    W-MODBUS uses the royalty-free ISM band at 2.4 GHz

What are the advantages of W-MODBUS?

  • No annoying laying of tax cables
  • Simple bridging of, for example, fire protection elements
  • Zeit- and cost savings
  • Flexible exchange or expansion
  • Easy integration into existing network
  • Quick and easy troubleshooting
  • Funcover width up to 500m (50-70m indoors with intermediate walls)
  • Individual settings possible for each device

What is Modbus & W modbus?

Modbus
Modbus is a communication protocol with which data can be exchanged between a master and several slaves. The protocol was developed by Gould modicon in 1979 to enable storage programmable controls to communicate with each other. Instead of elaborate, star-shaped wiring, the Modbus protocol enables simpler and more resource-saving installation.


W-Modbus
W-MODBUS is a radio-based further development of the proven modbus standard for the wireless connection of modbus-enabled sensors, controls and devices. W-MODBUS devices communicate via a wireless radio connection from lumenradio-regardless of the in-house Wi-Fi and without leaving the proven protocol standards. Thanks to the reliable and fault-resistant radio network, entire buildings can be networked and a large part of the Modbus RTU cables can be replaced.

How is a W modbus network built up?

A W modbus network consists of a W modbus gateway that is connected to the modbus client via an RS485 cable and wirelessly with up to 100 W modbus devices.
Thanks to the wireless connection, individual elements can be easily exchanged, added or removed within a few minutes. This makes Wireless Modbus a cost and time-saving communication protocol.

Eliminate disorders in the network - is that possible?

Thanks to the wireless connections, a possible troubleshooting is extremely easy. Instead of looking for faulty cables and devices in the system as before, the error analysis is now limited to checking the devices. Device variants with a display are particularly user-friendly: in the event of a fault (e.g. communication interrupted), the display shows a plain text diagnostic report. In this way, the current status of the device can be found immediately. That saves a lot of time and money.

Is communication in the network encrypted?
Yes, all communication in the W modbus network is encrypted with AES128.

How are W-Modbus devices supplied with electricity?
To put up a Wireless Modbus device, connect it to the power supply of your premises. A battery operation is not provided because the devices have to be reliably and permanently supplied with electricity to ensure trouble -free operation.

Is the integration of W modbus not expensive?

No! Our devices have a surcharge of around € 40 for the W modbus module. This is a small amount compared to the advantages of wireless installation.
In addition, the installation does not necessarily have to be carried out by specialist staff, since only the power supply needs to be ensured. The configuration then takes place via the wireless connection of the W modbus.
