INTEGRATION OF THE LHC POWER CONVERTERS WITHIN THE HIGH-LEVEL LHC CONTROL SYSTEM
S. Page · Prepared for · 2005
The LHC will use some 1700 power converters, each of which will be locally controlled by an embedded Function Generator/Controller (FGC) connected to one of ~70 WorldFIP fieldbuses. To operate the LHC, all power converters must be controlled and co-ordinated in a synchronised manner within the high-level LHC control system. This paper describes the architecture and systems involved in integrating the control of the power converters into the high-level LHC control system, including: (i) management of the FGCs on the WorldFIP bus, (ii) reception of commands and delivery of status data via the Controls Middleware (CMW), (iii) integration into the LHC Java client API, (iv) monitoring and reporting of failures and warnings via the LHC alarm system and (v) extraction of post-mortem data in the event of beam-loss or equipment failure. The paper also provides an overview of the XML-based development system that supports and documents all parts of the LHC power converter control system.
