LTE Cat.1 / M1 NB IoT RTU. The DB RTU Q7 comprises an embedded system based on container technology allowing new SW applications to be integrated, containing application SW including e.g. (SCADA) communication protocols, libraries, and lifecycle management logic as well as a bootloader and tools for development, debugging and deployment. The DinBox RTU Q7 uses IEC 60870-5-104 to communicate as a slave with the SCADA system (master). Other protocols such as MQTT, Modbus are also implemented. The DinBox can be extended by remote I/O through Modbus TCP and/or Modbus RTU. Thanks to the Modbus master implementation and the modbus-to-IEC104 slave mapping the DinBox RTU Q7 can be used as a gateway to connect other Modbus slave IEDs.The DinBox RTU Q7 can be mass managed by a DeMas (Data Management Software) back office tool or can be managed separately (Q1 2023). An internal I/O extension option allows to add I/O directly to the DinBox RTU Q7.
