EMERSON NA-0093 Information and Control Systems Platform

EMERSON NA-0093 Information and Control Systems Platform

Description 

The platform is based on the Emerson Ovation®  product line and also integrates key components  developed by Westinghouse for nuclear I&C  applications. As a distributed process control,  information and data management system,  Ovation offers a powerful, flexible and opensystem architecture, supported with field-proven,  industry-standard hardware, software, networking  and communications components. The extended  components support plant computer, monitoring and  various system-interface applications to meet nuclear  industry requirements.

Benefits

The I&C system platform presents true open  computing, allowing users to achieve higher  plant availability, reliability, efficiency, safety and  environmental compliance.

Extensive system benefits are realized through the key  elements of the Ovation product.

•  Network – A standards-compliant, fully redundant, highspeed Ethernet network using commercial hardware,  and copper or fiber cabling. Each originating drop  periodically broadcasts point value and status at the  appropriate frequency. 

•  Controller – Each fully redundant PC-based controller  interfaces to the I/O subsystem, performs data  acquisition, and executes simple or complex modulating  and sequential control strategies (up to 32,000 process  points per controller).

•  Input/output Modules – Modular industrial grade  I/O requiring no special handling, user addressing or  configuration. Up to 128 modules per controller of analog,  discrete, digital bus and special turbine-related I/O is available,  including advanced fault diagnostics and channel isolation. •  Workstations – Operator/engineering workstations  (Windows® PC-based) feature high-resolution display of  control/monitoring graphics, diagnostics, trending, alarms  and plant-status information with easy-to-use engineering  and configuration tools. The engineering station contains  a fully embedded relational database management system  storing configuration, process-point information and control  algorithm information. System and point data (including  user-defined fields) can be imported via user-friendly database  tools (e.g. Access or Excel). •  Historian – Scalable mass storage and retrieval of process data,  alarms, sequence of events (SOE), logs and operator actions for  5,000 to 100,000 point values. Presentation capabilities include  data queries, historical trending and SOE Reports. A bundled  reporting package allows for scheduled and triggered reports  to operators, engineers and maintenance personnel.

•  Connectivity Servers – Open system interfaces (ODBC,  NetDDE, OPC) provide innovative technology for securely  transporting real-time or historical process data directly to a  user desktop for critical analysis of plant performance data.  Data link interfaces to third-party devices and protocols such  as Modbus, Allen-Bradley, GE Mark V/VI, RTP I/O, Toshiba  and MHI are also supported.

•  Application Server – Redundant application servers execute  complex calculations and monitoring from a robust Nuclear  Applications Programs (NAP) library and data link interfaces  with external plant systems. Standard, pre-tested function  blocks based on IEC 61499/61131 standards significantly lower  development and testing time. Custom sub-applications can  also be created. 

•  Cyber Security – Westinghouse is leading the cyber security  assessment and compliance activities in the industry in  conjunction with the new AP1000TM plants, advanced  boiling water reactor (ABWR) and existing plants worldwide.  Using cyber security assessments, communication-isolation  techniques, physical security, cyber-secure networks and  operating systems, and the Ovation product security,  Westinghouse’s cyber security team provides practical, cybersecure solutions. 

•  Advant Ovation Interface (AOI) – A Gateway server connects  each safety division data network to the non-safety real-time  data network, providing strict one-way flow of real-time safety  system data for display and control. Data flow is strictly one  way from the safety to the non-safety subsystem.
