Upgrade brings nuclear power HMIs up to
date
Invensys Eurotherm has successfully upgraded an obsolete DEC VAX based HMI platform at a nuclear power station belonging to the British Nuclear Group.
Invensys Eurotherm has successfully upgraded an obsolete DEC VAX based human machine interface (HMI) platform at a nuclear power station belonging to the British Nuclear Group The Remote Emergency Indication Centre (REIC) project had two main objectives: the replacement an obsolete DEC VAX computer system with the EurothermSuite HMI, and the retention of the plant's many Solartron isolated measurement pods (IMPs)

Japanese approval for custody transfer system

Solartron IMP modules are in use in many conventional and nuclear power stations throughout the UK.
They are popular because they eliminate one of the most significant Scada implementation costs: signal cabling from the sensor to the measurement system and are environmentally hardened.
This project marks the first time that an IMP-based installation has had its life extended using Eurotherm HMI technology.

Control system takes an enterprise view
Invensys has introduced the world's first industrial system that goes beyond the plant or other industrial operations to provide a true enterprise view.
Enterprise control system shows its power
Invensys provided 100 journalists, industry analysts, customers and partners with a dramatic demonstration of the power of the new InFusion enterprise control system.
In terms of the overall REIC upgrade, the Eurotherm HMI communicates to the existing 3591C Solartron IMP modules via the existing S-Net system.
No modifications were made either to the Solartron IMP modules or Input channels, or the existing S-Net network.
The project consists of installations within three distributed plant areas, the REIC, the emergency control room (ECR) and the main control room (MCR).
Within the REIC building, the new system includes two EurothermSuite Operation Servers running Wonderware InTouch software, plus two printers.
The EurothermSuite system communicates to the original Solartron IMP modules using a Eurotherm software driver compatible with S-Net protocol.
One EurothermSuite client workstation, plus printer and communication module, is located in the remote ECR.
The TFT screen is mounted in the existing desk.
Meanwhile, two additional EurothermSuite clients, together with one printer and communication module, are mounted in the remote MCR.
These remote system workstations communicate over existing spare twisted pair cores via Ethernet.
This was achieved using remote mini bridge module pairs, which avoided the high cost of running new communication cables.
The system includes watchdog timer software to provide an alarm in the event communications to any PC Client is lost.
The Watchdog timer initiates alarms contact to the station alarm analyser to reflect this status.
All the new EurothermSuite servers and associated hardware are powered by existing UPS systems.
The server PC workstations and client PC workstations provide the visualisation of plant data via EurothermSuite Operations Server software.
Based on Wonderware InTouch Scada software the presentation of real time data via tabular and process mimic displays is intuitive and provides engineers and operators with a modern HMI.
Historical data is also collected by the system, and used to provide report displays.
Logs are produced from Excel Workbooks.
To date, engineers at British Nuclear Group are delighted with their new cost effective modern system, which is an addition to other similar systems already supplied to the site.
