Abstract

This paper presents the improvement of RF control system for PEFP (Proton Engineering Frontier Project). The upgrade design is based on the use of VME based MODBUS/TCP Multi-function board connected to the specific low level RF Controllers (LLRF) via distributed I/O modules and Serial communication modules. The control system was based on EPICS (Experimental Physics and Industrial Control System) from the end of 2004. Starting from release 3.14, it is possible to run the EPICS database on VMEBUS hardware with UNIX operating system. Installation and commissioning of the RF module is scheduled on 2005. Control system to integrated the RF System to the PEFP control system is implemented. Hardware, software and various applications are upgrade to support the operation of RF Control system [1]. In this paper, we describe control structure and scheme of the current RF Control System and upgraded one.
