DSG Series

Brand new platform design with state of the art techniques for monitoring and controlling.

DSG Series

Datawatt Smart Grid

Flexible design | Maximum security

The Datawatt Smart Grid (DSG) series is designed for operation in the Water, Energy and Industrial markets. The design operates under two main principles: flexibility and maximum security. Flexible housing ensures the DSG design fits all existing Datawatt hardware platforms, as well as being optimised for future applications.

The DSG is developed on Linux, a modern open source platform, well known for its reliability, stability and security; this allows the platform to meet all modern technical and security requirements.

Security

For the Water, Energy and Industrial market, security requirements are very important. The interpretation of these requirements is subject to change, which is why we adhere to ENCS-RTU-DA security standards and ensure the development of the DSG-Series is based on "security by design".

Protocols

Realtime IEC104, COAP, and Modbus protocols are implemented, with other protocols available on request. New protocol implementations can be easily created because of the use of Linux and C#.

PLC Programming

The PLC programs are made with the latest standard from Codesys based on IEC61131-3. This standard is the industrial protocol for control programs and used by many national and international organizations and companies.
