Diagnostic Use Case Examples for ITER Plant Instrumentation and Control | 85 |
|
||
ITER requires extensive diagnostics to meet the requirements for machine operation, protection, plasma control and physics studies. The realization of these systems is a major challenge not only because of the harsh environment and the nuclear requirements but also with respect to plant system Instrumentation and Control (I&C) of all the 45 diagnostics systems since the procurement arrangements of the ITER diagnostics with the domestic agencies require a large number of high performance fast controllers whose choice is based on guidelines and catalogues published by the ITER Organization (IO). The goal is to simplify acceptance testing and commissioning for both domestic agencies and the IO. For this purpose several diagnostic use case examples for plant system I&C documentation and implementation are provided by IO to the domestic agencies. Their implementations cover major parts of the diagnostic plant system I&C such as multi-channel high performance data and image acquisition, data processing as well as real-time and data archiving aspects. In this paper, the current status and achievements in implementation and documentation for the use case examples are presented. | ||

CODAC Core System, the ITER Software Distribution for I&C | 281 |
|
||
In order to support the adoption of the ITER standards for the Instrumentation & Control (I&C) and to prepare for the integration of the plant systems I&C developed by many distributed suppliers, the ITER Organization is providing the I&C developers with a software distribution named CODAC Core System. This software has been released as incremental versions since 2010, starting from preliminary releases and with stable versions since 2012. It includes the operating system, the EPICS control framework and the tools required to develop and test the software for the controllers, central servers and operator terminals. Some components have been adopted from the EPICS community and adapted to the ITER needs, in collaboration with the other users. This is the case for the CODAC services for operation, such as operator HMI, alarms or archives. Other components have been developed specifically for the ITER project. This applies to the Self-Description Data configuration tools. This paper describes the current version (4.0) of the software as released in February 2013 with details on the components and on the process for its development, distribution and support. | ||

Approaching the Final Design of ITER Control System | 490 |
|
||
The control system of ITER (CODAC) is subject to a final design review early 2014, with a second final design review covering high-level applications scheduled for 2015. The system architecture has been established and all plant systems required for first plasma have been identified. Interfaces are being detailed, which is a key activity to prepare for integration. A built to print design of the network infrastructure covering the full site is in place and installation is expected to start next year. The common software deployed in the local plant systems as well as the central system, called CODAC Core System and based on EPICS, has reached maturity providing most of the required functions. It is currently used by 55 organizations throughout the world involved in the development of plant systems and ITER controls. The first plant systems are expected to arrive on site in 2015 starting a five-year integration phase to prepare for first plasma operation. In this paper, we report on the progress made on ITER control system over the last two years and outline the plans and strategies allowing us to integrate hundreds of plant systems procured in-kind by the seven ITER members. | ||

SDD toolkit : ITER CODAC Platform for Configuration and Development | 550 |
|
||
ITER will consist of roughly 200 plant systems I&C (in total millions of variables) delivered in kind which need to be integrated into the ITER control infrastructure. To integrate them in a smooth way, CODAC team releases every year the Core Software environment which consists of many applications. This paper focuses on the self description data toolkit implementation, a fully home-made ITER product. The SDD model has been designed with Hibernate/Spring to provide required information to generate configuration files for CODAC services such as archiving, EPICS, alarm, SDN, basic HMIs, etc. Users enter their configuration data via GUIs based on web application and Eclipse. Snapshots of I&C projects can be dumped to XML. Different levels of validation corresponding to various stages of development have been implemented: it enables during integration, verification that I&C projects are compliant with our standards. The development of I&C projects continues with Maven utilities. In 2012, a new Eclipse perspective has been developed to allow user to develop codes, to start their projects, to develop new HMIs, to retrofit their data in SDD database and to checkout/commit from/to SVN. | ||
