SMART INDUSTRY SMART METERING ModBus/LoRaWAN® Bridge The ModBus/LoRaWAN® Bridge collects data from any ModBus RTU existing equipment and connects these devices to a public or private LoRaWAN® 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  LoRaWAN®, Class A  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 LoRaWAN® network  Battery life up to 10 years  IP55 QUALITY & RELIABILITY  RED, RoHS The ModBus/LoRaWAN® Bridge acts as a ModBus master. It manages a set of ModBus slaves connected on a wired bus (RTU mode). It communicates with a remote server via a public or private LoRaWAN® network. The sensor supports up to 10 different configuration profiles. Each profile can be configured remotely (periodicity of data collection, equipment address, ModBus function code). Once the configuration is completed, data collection starts 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. The LoRaWAN® ModBus RS485 Bridge is easy to use, deploy and maintain: - NFC tag for identification (product code, serial number and batch number) - Magnetic switch to activate/deactivate the sensor - LEDs 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 registers every 1 hour in SF12. It can also be powered from an external 9-24V / 300mW power supply.
