Indus Control System operating the Indus-1 and Indus-2 Synchrotron Radiation Sources facilities at RRCAT, Indore is a widely distributed system. It employs, for Indus-1 8 VME Controllers, 300 interface modules, 7 Operator Computers and for Indus-2 approximately 100 Layer-3 VME stations, 10 Layer-2 Supervisory Controllers, 11 Operator Computers and 6 Server Machines. The whole control system is being operated in shifts to provide synchrotron radiation from Indus-1 to users as well as carrying out commissioning experiments of Indus-2. To keep it up and running the faults encountered during its operation are rectified at site and complete observations and rectifications of the faults are recorded electronically by the shift crewmembers in a central web based fault information system. This System is based on three tiers software architecture and has been developed using Java Servlets, HTML, JavaScript and SQL Database. Using relational database, facilities have been provided by the system for logging, e-mailing, acknowledging, exploring and analyzing the faults of various sub systems. This paper briefly describes experience implementations and functionalities provided by the system.
