FIRST EXPERIENCES WITH CENTRAL WEB BASED FAULT INFORMATION SYSTEM
B. S. K. Srivastava · 2007
Indus Control System, which controls the Indus-1 and Indus-2 Synchrotron Radiation Sources at RRCAT, Indore, is a distributed computer system. It employs 8 VME Controllers, 300 interface modules, 7 Operator Computers for Indus-1 and approximately 100 Equipment Control VME stations, 10 Supervisory Controllers, 11 Operator Computers and 6 Server Machines for Indus-2. The machine is 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 in the system for logging, e-mailing, acknowledging, exploring and analysing the fault information of various sub systems. This paper briefly describes experience, implementation aspects and functionalities provided by the system.
