Description

The Watteco 50-70-109 is a Modbus/LoRaWAN bridge for anyone who needs to bring existing Modbus RTU equipment onto a LoRaWAN network. It collects data from the devices on its RS-485 bus and sends it to a remote server over a public or private network.

This is the Class C version. The bridge acts as the Modbus master: the server decides which functions and device addresses to query, and can also write to the registers of connected equipment. The sibling 50-70-080 is the Class A version.

Core Capabilities

Modbus master over LoRaWAN The bridge manages a set of Modbus slaves on a wired RTU bus. It does not interpret the commands. The remote server sets the functions and addresses, so you can read and write all variables of a Modbus or JBus slave.
10 configuration profiles Each of up to 10 profiles can be set remotely: collection period, equipment address and Modbus function code. Transmission cycles run from 10 minutes to 24 hours.
Battery or external power Run it from a 3.6 V / 3600 mAh lithium battery or from an external 9-24 V supply (300 mW). On battery, autonomy is over 10 years when sending 4 registers every hour at SF12, at +10 °C to +25 °C.
Simple to deploy An NFC tag holds the product code, serial number and batch number. A magnetic switch turns the unit on and off, and LEDs show activation and network pairing. The IP55 housing is fixed with the supplied screws and anchors.

Industrial Applications

Electrical submetering: Index reporting from submeters in tertiary buildings and industrial cabinets.
Boiler room energy reporting: Read produced energy from meters such as Sharky or Kamstrup.
PLC and BMS monitoring: Remote monitoring of PLCs and building management systems through state register readings.
Remote control: Write to a PLC register to force a motor or valve.
Refrigeration alerts: Respond quickly to a refrigerated unit failure.

Technical Integration

Connectivity: LoRaWAN Class C on the EU 863-870 MHz band, +14 dBm transmit power, AES128 encryption. Activation by OTAA or ABP.
Modbus side: RS-485, 2-wire, half duplex, Modbus RTU, with overvoltage protection and a 120 Ω termination jumper you can fit or remove. Baud rates from 1.2 to 115.2 kbit/s.
Server side: The application layer is ZCL (ZigBee Cluster Library), to be interpreted by your remote server. Data rate, parity, data bits, stop bits and wake-up periods are set from the server.
Power: 3.6 V lithium battery or external 9-24 V DC. The bridge does not power the connected equipment.
Mounting: Wall mounting with the supplied screws and anchors. A DIN-rail kit is covered in the quick start guide; fitting it lowers the housing to IP50. Variant note: 50-70-080 is the Class A version.

Frequently Asked Questions

What is the difference between the 50-70-109 and the 50-70-080?

The 50-70-109 is the Class C version of the Modbus/LoRaWAN bridge. The 50-70-080 is the Class A version. Both are listed in the Watteco datasheet.

Which Modbus modes and baud rates does it support?

Modbus RTU over RS-485, 2-wire half duplex. Baud rates are 1.2, 2.4, 4.8, 9.6, 19.2, 38.4, 57.6 or 115.2 kbit/s.

How is it powered?

By a 3.6 V / 3600 mAh lithium battery or an external 9-24 V, 300 mW supply. It does not supply power to the equipment connected to it.

How long does the battery last?

Over 10 years when transmitting 4 registers every hour at SF12, in a +10 °C to +25 °C range. Shorter reporting intervals will reduce this.

Can I write to registers as well as read them?

Yes. The remote server can read and write the bits and registers of the connected Modbus equipment.

What temperature range and protection rating does it have?

Operating temperature is -10 °C to +50 °C. The housing is rated IP55 (IP50 with the DIN-rail kit fitted) and has UL94-V0HB fire resistance.
