DCS Innovation by SIL and Non-SIL Unified Architecture - Hitachi Approach on G-HIACS (R800FS/R900)

Abstract

In response to the demand for safe, secure and smart systems, Hitachi, Ltd. has been developing a new generation of DCS, the Global-Hitachi Integrated Autonomous Control System ("G-HIACS¹", based on its highly successful HIACS-7000 architecture. The G-HIACS product family comprises the SIL2-rated R800FS/HSC800FS νSAFE² (pronounced "nu-SAFE") Functional Safety Controller and the R900/HSC900 General Purpose Controller. This paper summarizes the ongoing technical development successes, presents the key results of Hitachi activities within the Canadian nuclear market, and maps out our medium-term goal of fully integrating the two platforms into a harmonized architecture (the G-HIACS "Unified Architecture").
