Control Systems What is DIASYS?
The Digital Intelligent Automation SYStem, or DIASYS, is a distributed control system (DCS) developed to maximize plant performance while offering high reliability and utilization rates.
The DIASYS series, developed as a control system for thermal power plants in the 1980s, has been adopted in more than 2,100 projects to date and boasts a delivery track record spanning more than 60 countries (as of June 2016).
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.
MHPS 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.

History of the DIASYS Series
The DIASYS has its roots in a system that used a DEC mini-computer at the beginning of the 1980s. In the late 1980s, a single-board computer manufactured by Intel was adopted to develop a direct digital control (DDC) system.
At the same time, MHPS developed the original Interpreter DDC Oriented Language (IDOL) as a tool for creating a Program Oriented Language (POL). Through soft updates and support for various platforms (DOS, Unix, Linux and Windows-based systems), IDOL is still used to this day.
Around 1990, MHPS developed its own control modules to replace the modules it had mostly been purchasing externally. Using CPU modules that employed the latest 32-bit CPUs of the day (M386CPU), MHPS updated almost all of the modules and power supply units used in its control equipment.
At the time, MHPS had already been designing and fabricating control boards in-house, and progressed to the in-house production of the modules from this point forward.
Later, in the late 1990s and early 2000s, MHPS undertook two major revamps of its control equipment, culminating in the release of what are today known as DIASYS Netmation, and DIASYS Netmation4S, which also allows development as a safety instrumented system.
