DinBox RTU M4: SCADA IEC 60870-5-104/Modbus device, now with TLS and basic VPN IPsec security!
The DinBox RTU M4 is a micro RTU with LTE Cat. 1/GPRS communication integrated for SCADA applications. The remote terminal unit maps Modbus RTU registers to IEC 60870-5-104 objects and can also perform I/O alarming or other applications. It is a cost-effective all-in solution to integrate your devices in an IEC 60870-5-104 environment. The device is equipped with VPN IPsec & TLS security. On the immediate roadmap is the integration of IoT protocol MQTT.

The DinBox RTU M4 is a low-cost micro RTU with built-in wide range AC power supply. The power supply comes with a supercap back-up, in order to ensure the required energy to communicate with the SCADA system, even after a mains  power supply disconnect. Direct WAN communication is possible thanks to the built-in Sierra Wireless communication module. Everything is managed by a powerful Cortex M4 microcontroller. Finally, the RTU is built into a DIN rail mountable housing.

The DinBox RTU M4 uses IEC 60870-5-104 to communicate as a Slave with the SCADA IEC 60870-5-104 Master system. The DinBox has 8 active digital inputs, which enables monitoring events when a change has been detected. Furthermore, it has 2 digital outputs which can becontrolled via SCADA commands, and 2 analogue inputs to monitor.
Thanks to the modbus RTU-to-IEC104 mapping the DinBox RTU M4 can be used as a gateway to connect other modbus slave IEDs. Also the DinBox RTU M4 has the capacity to be connectecd by (up to) 6 Master SCADA IEC 60870-5-104.

Authentication, integrity and security are provided per application or service running on the RTU by protecting the transport layer of the protocol stack with TLS (Transport Layer Security). Integrating TLS in a non-TLS SCADA setup can be done by installing a TLS Proxy service. This service runs on the trusted network and serves as an endpoint towards the TLS RTU. Also the RTU has an ethernet port which allows LAN or WAN routing.

The DinBox RTU M4 can be remotely managed for mass firmwares (Q4 2020), remote parametrization and 'Plug & Play automatic commissioning (Q4 2020).
