The Cryogenic Data Acquisition and Control system (CRYO-DACS) at IUAC was commissioned successfully in the year 2002 and has been continuously in operation since then with uptime better than 95%. The aim of CRYO-DACS is to control and acquire many analog and digital cryogenic parameters of super conducting LINAC and related equipments like beam-line cryostats, helium compressors, cryogenic distribution etc. The complete system is implemented using two VME crates, housing I/O modules, placed far apart and interconnected using Ethernet. The software implementation and maintenance have also been trouble-free which used IOWORKS as the development tool for embedded CPUs running VxWORKS. The OPC Client was developed using VB6 & MSACCESS RDBMS for data logging, viewing and trending under Windows 2000 stable server. In summary, this paper will elaborate the implementation, use and related failures faced for last 10 years and the subsequent corrective actions taken to keep the system running for such a long time round the clock along with some future plans.
