Mitsubishi smartRTU uses hacker proof SSL encrypted VPN tunnels

Mitsubishi Electric has introduced a range of intelligent  RTUs for the reliable monitoring and control of remote assets.  The smartRTU supports protocols such as DNP3 and IEC 60870.  SSL technology provides protection for essential infrastructure data against potential attacks from hackers and cyber terrorism.

Reliable control for remote sites

Automation control systems are increasingly used at remote locations across the UK and worldwide.  Applications such as control of water resources and the processing of for raw materials require innovative solutions to ensure fully automated production process to be controlled remotely and allowing personnel employed on site to be reduced to a minimum.

They use intelligent remote terminals that supply data to the enterprise system over long distances from diverse plant systems such as oil and gas pipelines, switching stations, tunnels or sewage treatment plants. The solution supports GPRS, EDGE, Ethernet, radio modem or satellite modem technology to transfer the data and in the future, PLC (Power Line Carrier) will also be an option.

Proven Hardware

The Mitsubishi smart RTUs contain proven industrially hardened control and I/O modules which make them extremely robust as well as suitable for use in extreme temperature conditions. The smart RTU is operated by means of a modest energy supply provided for example by a photovoltaic system or a wind turbine. A new intelligent add-on data transfer module looks after the whole complex process of protocol handling.

To use the smartRTU, users need only to create the monitoring and control logic required in the built-in IEC-61131 PLC programming language. An expanding library of protocols and pre-configured function blocks required for the relevant industry such as protocol standards for the water and waste water, infrastructure, oil and gas industries or the communication standards DNP3, IEC 60870-5 and IEC 61850 for the energy industry is being developed on an ongoing basis.

Three versions of smart RTU are available to match the automation system size and the Mitsubishi processors in use.  They are for use with the FX-Series PLCs for small systems, L-Series PLCs for medium systems and Q-Series PLCs for large and redundancy applications.
