LoRaWANTM - MODBUS RS485 BRIDGE The LoRaWANTM ModBus RS485 bridge collects data from any ModBus RTU existing equipment and connect these devices to a public or private LoRaWANTM network. The Bridge has the capability to change the behaviour of the ModBus device by writing into its registers.

APPLICATIONS  Monitoring and control of ModBus slave equipment from a remote server via a public or private LoRaWAN network : inputs, outputs, electrical machines, measuring equipment ...

BENEFITS & KEY FEATURES  LoRaWANTM, Class A, Classe C  Easy to use and deploy  Management of all the variables (read and write) of a ModBus (or JBus) RTU slave equipment from a remote server via a LoRaWANTM network  Battery life >10 years  IP65

QUALITY & RELIABILITY  RoHS, CE

The LoRaWANTM ModBus RS485 Bridge acts as a ModBus master. It manages a set of ModBus slaves connected on a wired bus (RTU mode). It communicate with a remote server via a public or private LoRaWANTM network. The sensor supports up to 8 different configuration profiles. Each profile is configurable remotely (periodicity of data collection, equipment address, ModBus function code). Once the configuration is complete, data collection start automatically and periodically. At every wake-up, the bridge transmits the ModBus commands to the ModBus connected devices. The response of the ModBus connected devices is transmitted to the remote server. The remote server can achieve a write request into the bits or registers of a ModBus equipment.

The bridge does not interpret the ModBus (or JBus) commands: the list of functions to be executed and the addresses of the devices are set by the remote server. As an option, it is possible to force the wake-up of the sensor from an external signal. The LoRaWANTM ModBus RS485 Bridge is easy to use, deploy and maintain: - NFC tag for identification (Part number, serial number and manufacturing number) - Magnetic switch to activate/de-activate the sensor - Buzzer with different melodies for activation, deactivation and network pairing When powered through a 3.6V/3,6Ah lithium battery, the autonomy of the bridge is more than 10 years when transmitting 4 bytes every 30mn in SF12. It can also be powered from an external 9-24V / 100mW power supply.

Configurable parameters from the LoRaWANTM remote server

- Data rate, parity, number of data bits, number of stop bits - Wake-up periodicity to read/write ModBus - Transmit measurement periodicity

Transmit duty cycle

The LoRaWANTM remote server must properly set the transmission duty cycle to comply with ESTI EN 300-220-1 (page 24) regulation. This regulatory constraint limits the volume of transmitted data.
