Modbus table

Data model

µWiotys supports holding register data model.

Registries 0x0 to 0x05 is filled with device configuration upon GW startup.

All other registers are filled upon LoRaWAN message sent by the device.

A register set to default value 0xFFFF (or 0x7FFF for signed values) indicates that the value has never been updated.

There could be several causes:

  • the device didn't send any payload yet.

  • this is not the proper modbus table to read for the device type.

  • the registry isn't available for this model. For instance NKE 50-70-139 only has 2 temperature probes, therefor temperature 3 will always remains 0x7FFF

  • the registry isn't activated for this model. For instance NKE 50-70-016 has 10 contact state. However some could be deactivated on sensor configuration (if so the modbus table will always remains 0xFFFF).

Common table

This table is present and identical for all devices.

Depending on the type and configuration of your connected LoRaWAN device, you will get one or several values. Please refer to your device manual. If your device only return one value for temperature, it will be available in temperature 0 and updated with each new payload. If your device returns 2 values for temperature, it will be available in temperature 0 and 1, check out the manufacturer documentation for more informations.

Diris B-10 Lora Socomec

There is a dedicated Modbus table for this product. Please refer to Socomec manual.

Modbus

Depending on the type and configuration of your connected LoRaWAN device, you will get one or several values. Please refer to your device manual.

This table is dedicated for LoRaWAN to Modbus RTU RS485 devices. Please note that your LoRaWAN device must be configured with proper RS485 parameters matching your secondary BMS configuration : baud rate, parity, stop bit, data bits, slave, register address. Contact Wi6labs support for this initial configuration
