MHI Develops "DIASYS Netmation 4S" Control System Complying with IEC 61508 (2010) (SIL3) International Standards On Functional Safety
Tokyo, August 27, 2013 - Mitsubishi Heavy Industries, Ltd. (MHI) has completed development of the DIASYS Netmation 4S, a control system complying with IEC 61508 (2010) (SIL3) international functional safety standards. Developed for monitoring and control of thermal power generation plants and other facilities, the DIASYS Netmation 4S is one of only a few examples - and the first in Japan - of products to satisfy the stringent hardware and software requirements of IEC 61508 (2010) guidelines in terms of both "control and protection" functions. Certification was acquired from the third-party international testing and certification organization TÜV SÜD, based in Germany. After receiving formal recognition of the DIASYS Netmation 4S's world-leading reliability, MHI now plans to proceed toward inaugurating shipments of the new system from spring 2014.
The certification received for the new system, IEC 61508 (2010), is the second edition of standards initially introduced in 2000; it includes newly added requirements pertaining to design and development management systems, software and security.
IEC 61508 is the global standard relating to functional safety. Today its range of applications is broad, including not only plants of all kinds but also automobiles, railways, aircraft and factory automation. IEC 61508 also forms the basis of ISO 26262 automotive safety standards, etc. Under IEC 61508 guidelines, machine hardware and software reliability is evaluated according to the "SIL" (safety integrity level) index. SIL3 is the highest level of safety sought from thermal power generation, chemical, environmental and other plants.
In addition to acquiring IEC 61508 certification, the DIASYS Netmation 4S has also received IEC 62061 and EN ISO 13849 certification applied to functional safety of machines. It was also among the first systems qualifying for IEC 61131-6 certification, a new standard introduced in 2012 for the functional safety of controller units. The DIASYS Netmation 4S is the first system in the world to receive IEC 61131-6 certification in the field of power plant control systems.
Ahead of the commencement of shipments next spring, in November the DIASYS Netmation 4S will be shown at System Control Fair 2013 to be held at Tokyo Big Sight in Ariake, Tokyo.
