Development, implementation and remote operation of twin source vacuum system through TS-DACS

Twin Source (TS) experimental setup is a stepping stone towards ITER based Diagnostic Neutral Beam (DNB) source from existing single driver based ROBIN experimental setup in IPR, India. The control system consists of (i) Master control system (S7 400PLC) (ii) Remote I/O (ET200S) for vacuum and cryogenics. Depending upon the need of isolation to avoid ground loop and noise immunity, fiber optics PROFINET communication is used between Master control system and remote I/O station. For the development of control core program, Siemens step 7 tools and for SCADA function(Supervision, Alarm and Archiving) CODAC core system 4.0 is used. For the data acquisition, National Instruments (NI) PXIe system and NI 6259 digitizer cards have been considered. The LabView real time software has been used for real time data acquisition application. This paper discusses in detail about development, successful implementation and remote operation of vacuum system through a twin source data acquisition and control system (TSDACS)
