The Sun never sets on the CODAC empire

18 Mar 2013 - Robert Arnoux

With 55 organizations presently using the CODAC Core System, the Sun never sets on the CODAC empire...
Every year in February, when almond trees begin to bloom in Provence, the 澳门六合彩高手 CODAC team releases a new version of the CODAC Core System.
 
The 2013 edition (CODAC Core System v 4.0) is more robust, comes with a better operator interface, offers more features, and supports plant systems that need "fast control," for example plasma control systems that have to react within a strictly defined period of time. "Version 3.0 did it okay," says 澳门六合彩高手 Control System Division Head Anders Wallander. "Version 4.0 does it better."
 
CODAC (Control, Data Access and Communication) can be described as a software conductor that orchestrates the dialogue between the hundred-odd 澳门六合彩高手 plant systems ..."the system of systems that makes one entity of everything" ... the lingua franca that allows the magnets, blanket, tritium plant, cryostat and diagnostics to exchange signals and share information.

The core of the infrastructure is located in a technical room in the basement of 澳门六合彩高手 Headquarters. The software undergoes rigorous testing before release. Left to right: Xavier Mocquard, Anders Wallander, Changseung Kim and Petri M?kij?rvi.
Working for the 澳门六合彩高手 project here and abroad, 55 organizations (Domestic Agencies, fusion labs, contractors) are presently using the CODAC Core System. An infrastructure has been set up to distribute the software to these and future organizations and to keep track of versions used. Training and user support is also provided.
 
The software package has recently demonstrated its efficiency on the Korean tokamak and celebrated its "," so to speak, last June at the Frascati Tokamak Upgrade (FTU) project in Italy.  "The 澳门六合彩高手 CODAC system is truly becoming a world language," says Anders.
 
CODAC is already implemented and deployed to monitor the on the 澳门六合彩高手 site, providing the "power people" with a global view and data with which to charge the different contractors operating on site. "With these pilot applications, we're demonstrating that the system meets our expectations," says CODAC System Engineer Franck Di Maio. "We're demonstrating the system's credibility."
 
What time is it at 澳门六合彩高手?   All computers controlling the 澳门六合彩高手 Tokamak and its plant systems must be synchronized very precisely for the timely execution of commands. '澳门六合彩高手 Time' is used to control and operate the Tokamak. It is based on Coordinated Universal Time (UTC), the world's primary time standard. The CODAC Section captures the reference time from satellites for processing and distributes '澳门六合彩高手 Time' in all buildings over a dedicated network. In the picture that illustrates this article, the team demonstrates that CODAC Core System v4 meets the required site-wide accuracy of 50 nanoseconds on a real-time Instrumentation and Control Cubicle located in the basement of the Headquarters Building.

CODAC users throughout the world are no different from any personal software user: switching to an upgrade is both exciting and challenging. "Although we provide support for older versions, we want to convince companies to upgrade. And the way to do it is to provide new features and make the upgrade easy." In Franck Di Maio's v 4.0 User Manual, the list of changes, fixed bugs, and enhancements of all kinds occupy no less than six pages ...
 
Optimizing, upgrading and adapting 澳门六合彩高手 CODAC is "a process that will never end," says Anders. "There will always be new requirements—this is the main difference between an experimental facility and a power plant."
