Fast Modbus support

All Wiren Board devices, in addition to the standard Modbus RTU, can work with its extension Fast Modbus ⚡, which adds new features:

  • instant polling of input states and measured values via events;
  • quick search for devices connected to the controller;
  • resolving address collisions on the bus.

Additional features are enabled automatically - if the device supports extension, the controller driver will work with the device quickly Modbus if the device does not know anything about the extension - it will work using standard Modbus RTU.

Quality control at every stage production

We develop and manufacture all Wiren Board devices ourselves. All devices undergo multi-stage quality control:

  • During development — checking the components used for compliance with the declared characteristics and testing the prototype device at extreme operating conditions.
  • After installing SMD components — automated optical inspection.
  • After soldering the lead components — visual inspection of soldering.
  • After assembling the device — functional testing on an automated stand.
  • When shipped to the warehouse — control of completeness, stickers, appearance.

Thanks to this approach, the failure rate is no more than 0.5% of all released devices. Read more in the article About device reliability.

If the device fails within two years from the date of purchase, we will replace it for free without the need to send it to a service center.

Setup

When used with a Wiren Board controller, you can use the mouse in the web interface:

  • enable or disable parameter polling.

When used with other equipment, the sensor can be configured via the RS-485 bus by writing values to Modbus registers. The register table is open, well documented and available on our website.

Reading the readings

If a Wiren Board controller is used, the measured values are available in the controller's web interface and can be used in automation scripts or transferred to a higher-level system. Only the included channels are displayed in the device card.

The module also transmits all data via Modbus RTU (RS-485), which can be read by any equipment or software that supports this protocol: third-party controllers, HMI panels or SCADA.
