  We are now operating a web-based monitoring system of PAL control system with MAC Power PC. In order to expand the IOC’s web-based monitoring system, we are trying to use the X86/Linux platform. With the experience which we got in developing the web-based monitoring of EPICS-IOC based on MAC Power PC, a web-based monitoring system with an X86 Intel PC based on a new concept has been developed for lower costs, easier access and use. Its operating system employs Linux Fedora Cor·104. In order to drive the web-based monitoring system, EPICS Base 3.14.8 and MySQL 4.0 have been installed in the Linux Fedora Core 4. Archive engine with C language and EPICS channel access library are programmed to store the data. As a result of using the web-based monitoring system based on the X86 Intel PC, we have achieved its easier access and use, more convenient maintenance. Performance of the web-based monitoring system with an X86 Intel PC will be discussed.

  The former control system of the bending MPS (Magnet Power Supply) has a three-layered architecture. It was developed by in-house members in early 1993. It is upgraded based on EPICS as the protocol for the full upgrade of the PLS control system. We have replaced the former VME 68K CPU boards with OS-9 to new Power CPU boards operated by VxWorks as IOC in the linac klystron gallery. The upgraded bending MPS control system consists of a MVME5100 EPICS IOC core in the lower level control. It is implemented with the MEDM tool of EPICS to provide friendly Graphical User Interfaces. This paper describes the VME IOC and OPI and embedded local controller in MPS cabinet used for the bending MPS control in the PLS linac
