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
