Automation SYStem, or DIASYS, maintains high reliability and an impressive utilization rate as a system, while incorporating the extensive expertise and control technologies Mitsubishi Power possesses as a plant manufacturer, culminating in a distributed control system (DCS) with ease of handling for everyone, from operators to plant engineers and maintenance personnel.

The DIASYS series, developed as a control system for thermal power plants in the 1980s, has been adopted in more than 2,700 projects to date and boasts a delivery track record spanning more than 60 countries (As of End of September 2022).

DIASYS Netmation, which was released in 2000, has been highly regarded for the high reliability of its control equipment, and its user-oriented operational monitoring and engineering tools. The solution is not just a great fit for thermal power plants; it also works as a control and monitoring system for a variety of facilities and products, including rocket launch facilities, LNG carriers, plant management systems and office building management systems.

In a further development, DIASYS Netmation4S preserves all the ease of use found in DIASYS Netmation together with Functional Safety Certification (IEC61508:2010) obtained in 2013. This has enabled dramatically improved hardware reliability, and the incorporation of protective circuits that meet Safety Integrity Level (SIL) requirements.

Mitsubishi Power has also released a secure gateway to support the development of secure systems even on open networks, making it easier to collect data for customer value creation utilizing the latest ICT including remote equipment monitoring and preventative maintenance.

With a lineup that caters to everything from small to large systems and from equipment control and monitoring to protective functions, the DIASYS series goes a step further in contributing to customer businesses.
