Phase 3

The RadICS platform has now been supplemented in Phase 3 by the proprietary toolset Radiy Platform Configuration Tool (RPCT).  RPCT provides a complete IDE so End Users are able to create safety system logic and hardware configuration on a convenient graphic platform. The IDE allows the user to define his control or safety logic, incorporate platform diagnostics in his logic, define signals that can be tuned online, and configure both the tuning station and the non-interfering monitoring system. The user’s control or safety logic is designed using the certified function block library.

All 3 phases of RadICS are based on 3 unchanged concepts: firstly, RadICS is structured physically like a safety PLC, with a Logic Module (LM) and 14 slots which can be populated with any of the I/O modules or an optical communications module which allows for expansion to 3 levels of chassis. Secondly, RadICS is completely implemented using FPGAs – there are no micro-processors. This provides exceptional speed (10 ms guaranteed cycle time), inherently good immunity against cyber security since it is impossible to reconfigure the FPGAs remotely and the elimination of the need for any complex operating system.  The third  fundamental concept is separation of platform logic and User Application Logic (UAL), which provides stability of the platform no matter what the application is.

During Certification Phases 1 and 2, the UAL was implemented for the End-User using Quartus II software from Altera. In Phase 3, the IDE toolset RPCT has been added and integrated as the design tool for the UAL. This provides a complete state-of the-art user-friendly package so the End-User can cost-effectively design his own UAL. This UAL is stored outside FPGA and there is no need  to recompile FPGA project each time the UAL has been changed. The End-User’s UAL is designed in RPCT using the certified Function Block Library, consisting of over 80 fundamental blocks and allowing the End-User to define reusable composite blocks. The composition of the platform modules has no changes.

The SIL 3 Certificate was updated at Phase 3. It now demonstrates full compliance with IEC 61508 for LM, DIM, DOM, AIM, AOM, OCM and RPCT and states that single configuration of RadICS Platform is SIL 3 capable and can be used for nuclear safety applications.

Another important achievement of Phase 3 is RadICS Platform successful qualification at Kinectrics laboratory and subsequent release of Safety Evaluation Report issued by US NRC on July 31, 2019.
