Product description
Overview
YO Modbus bridges between the Modbus network and the LoRaWAN. It allows users to read data
via Modbus RTU from slave devices and to send it via LoRaWAN. One YO Modbus device provides
capacity to create up to 150 Modbus queries and to send them in up to 30 different LoRa packets.
These are sent in LoRA packets of up to 5 queries each (i.e. maximum of 30 packets).
