The NBI Control System for the EAST

In this paper, a description of the control system’s software and hardware architecture for the Experimental Advanced Superconducting Tokamak neutral beam injector (NBI) is introduced. The chosen platform is a CPCI-based and PXI-based computerized network system. Three PXI/CPCI crates house several boards for performing analogue signal acquisition, analogue voltage generation, signal conditioning, digital input detection and digital output generation. Two server computers running CentOS 6.3 operating system act as control server and data server respectively. A virtual instrument for the timing system is developed with LabVIEW 2010 on the PXI-based platform. Graphical user interfaces for monitoring and programming purposes are developed with LabVIEW and WinCC integrated development environments by using TCP/IP network protocol under the Windows operating system. Experimental results demonstrate that the visualization and automation of NBI experimental operations are successfully implemented by using the functions of remote monitoring, interlock protection, and data processing.
