smartRTU

Remote Terminal Unit based Monitoring and Control

smartRTU

Communicate securely to SCADA systems, the smartRTU addresses requirements for 100 % reliable remote surveillance and control of distributed assets, even in extreme climates. With powerful functions like diagnostics, alarm and event-storage and time trend data buffering, it meets the challenges of managing massively distributed assets such as data security, interfacing issues, data continuity and reliable communications.

Mitsubishi Electric‘s meets these demands with the smartRTU. It supports protocols such as DNP3 and IEC 60870. The smart- RTU combines the reliability and robustness of our standard PLC technology with a smart communication gateway, the ME-RTU gateway. Depending on the size and complexity of the application, select the required smartRTU power, pairing the ME-RTU with either an FX-, L-, or Q-Series PLC.

Your benefits

Mitsubishi Electric‘s smartRTU combines the needs of a large number of industries into a single device that is simpler than conventional RTUs, yet provides powerful capabilities that can be easily deployed and administered, even by staff with low skill levels. The smartRTU is scalable from a handful of sites to many hundreds with remote configuration management.

The Mitsubishi Electric smartRTU

  • Minimizes your engineering costs through central engineering
  • Deployable in brownfield applications due to multiple fieldbus support
  • Copes with demands of small up to large sites
  • Very low power consumption
  • Stores and forwards your data by an embedded historian that allows timestamped event logging and data sampling for extended periods of time
  • Communicates your data-packets via hacker proof SSL-encrypted VPN tunnels
