ITER CODAC Core System at FTU: State of the art and new perspectives

Abstract

Recently the slow control of the MFG1 motor flywheel generator powering FTU toroidal magnet has been redesigned within the framework of the ITER CODAC I&C architecture [1] using the software package CODAC Core System (CCS).In this paper the progress made towards the final commissioning will be detailed, focusing on the system integration in the FTU control system supervisor through a software bridge and a multithreaded channel access interface to the Plant System Host, emphasizing the problems found so far and their solutions. The development and implementation of the alarm handler, the logging system and the data archiving system will also be illustrated, as well as the relevant monitoring and visualization interfaces developed on the Mini-CODAC node with the standard EPICS tools BEAST, BOY and BEAUTY. Furthermore, the tests run on FTU that finally led to a successful commissioning will be thoroughly discussed.Due to the satisfactory outcome of the project, and taking advantage of the release of the new CCS v 3.0 introducing the management of fast controllers, an account on a possible application of the CODAC ITER fast control architecture at FTU will also be given, taking the FTU real time feedback system as the first test case, to be further extended to newly implemented fast controllers.
