Background: Institute of Plasma Physics

Chinese Academy of Sciences (ASIPP) is cooperating with India's Tata Consultancy Services (TCS) and International Thermonuclear Experimental (ITER) to build a new measurement and control system engineering for high temperature superconducting current lead (HTSCL) under the framework of CODAC (Control

Data Access and Communication). Purpose: This study aims to design a data acquisition and control system for this project that was implemented according to the requirements of CODAC system. Methods: It contains the fast controller

the conventional Programmable Logic Controller (PLC) system

i.e. the Siemens 300 series and 400 series PLC

is applied for slow controller and data acquisition sub-system

interlock sub-system using the integrated module of CODAC. Fast controller and quench detection sub-system were implemented by using National Instruments (NI)’s NI PXIe-6259

NI 9219

etc. modules and the LabVIEW programming with embedded Experimental Physics and Industrial Control System (EPICS) interface. Each subsystem is developed and applied by following the framework standard of ITER CODAC. Results: This proposed system has passed the second round of testing

showing that it full fills the experimental requirements of HTSCL test. Conclusion: The measurement and control system of HTSCL was designed completely in accordance with of ITER CODAC standard

it follows strictly the CODAC specification of ASIPP and ITER international organization. Most importantly

it’s the first time to combine CODAC and interlock protection system of ITER for real physical performance test

it can be used as a model of CODAC norms in the future. Abstract
