Communication process: 1.Upper system (SCADA, PLC, HMI) connects a LoRa modem by RS485 or USB port 2.Upper system as Modbus master sends request command to LoRa modem 3.LoRa modem transmit the request command to LoRa Modbus IO module over LoRa wireless network 4.LoRa Modbus IO module receives and responds LoRa modem only forward message between upper system and LoRa Modbus IO module. One LoRa modem can communicate with multiple LoRa IO modules About CWT LoRa device wireless communication 1.Open air communication distance is about 3KM, distance will be affected by obstructions 2.Communication in building, the distance through the wall is about 5-6 layers of wall 3.Can setup LoRa communication parameters by config tool CWT-L3-LoRa Features 1 Basic Feature 2 Technical Specification 3 Size 4 Package list Module×1, antenna×1, USB cable×1
