	An accelerator has various subsystems like Magnet Power Supply, Beam Diagnostics and Vacuum etc. that are required to work in a stable manner to ensure required machine performance. Logging of system parameters at a faster rate plays a crucial role in analysing and understanding machine behaviour. Logging all the machine parameters consistently at the rate of typically more than 1 Hz has been the aim of a recent data logging system upgrade. Nearly ten thousand parameters are being logged at varying intervals of one second to one minute in Indus accelerator complex. The present logging scheme is augmented to log all these parameters at a rate equal to or more than 1 Hz. The database schema is designed according to data type of the parameter. The data is distributed into historical table and intermediate table comprising of recent data. Machine control applications read the parameter values from the control system and store them into the text-files of finite time duration for each sub-system. The logging application of each subsystem passes these text files to database for bulk insertion. The detail design of database, logging scheme and its architecture is presented in the paper.

	G. Verma, B.B. Biswas, S.K. Jain, M. Kalra, D.A. Roy BARC, Mumbai, India
	An embedded PC based Controller module, named System Controller Module (SCM), has been developed at Reactor Control Division(RCnD), BARC. This module uses standard PC-104 bus based CPU module integrated with a protocol translator card to provide an interface between the CPU module and VME bus. The signal interface between PC-104 bus of CPU module and translator card is achieved through stackable connectors. SCM can be interfaced with 16-bit slave I/O modules on VME bus for Data Acquisition and Control. This development provides low cost PC based platform for developing I/O intensive embedded system requiring high processing power. SCM module is fully compatible with PC architecture and is available in Double Euro modular form factor. Module has self diagnostics features to test software integrity using onboard watchdog timer. The module provides dual Ethernet link for communication. The SCM has been assembled, integrated and successfully tested along with VME based high speed data acquisition system (Machinery Protection System), which has been developed in RCnD for condition monitoring of rotating machines. SCM acts as a configuration controller and data manager for this system.

THCC02	Controls Architecture for the Diagnostic Devices at the European XFEL	controls, monitoring, site, electron	121
	O. Hensler DESY, Hamburg, Germany
	The X-ray laser is an 3.4-km-long facility which runs essentially underground and comprises three sites above ground. For controlling all diagnostic devices like toroids, BPMs or BLMs, it is planned to use the new MTCA.4 crate standard instead of VME. ATCA is an emerging standard from the Telecom Industry and adapted with the PICMG MTCA.4 branch for physics usage. The communication on the backplane utilizes the high speed serial PCIe communication plus precise clock lines and SATA interface. The MTCA.4 hardware supports hot-plug mechanism and remote monitoring and control via IPMI over Ethernet. Some of the diagnostics will be connected to 16Bit ADCs with up to 125Mhz sampling rate from Struck company or to an internal DESY development call DAMC2. The software architecture is based on the DOOCS control system known from the FLASH accelerator. The raw data from the ADCs will be read via DMA transfer by one server process. Then this raw data will distributed locally on the CPU using a message passing system based on the ØMQ project. The receiving server processes are calculating these data into engineering units then. Everything works in an event driven way.

THPD10	Modular Beam Diagnostics Instrument Design for Cyclotrons	controls, cyclotron, EPICS, extraction	154
	N. Chaddha, R.B. Bhole, P.P. Nandy, S. Pal, S. Sahoo VECC, Kolkata, India
	The Cyclotrons at VECC, Kolkata i.e. Room Temperature Cyclotron (RTC) and Superconducting Cyclotron (SCC) comprise of internal and external beam diagnostic systems. These systems provide the beam developer with position, intensity, beam profile, a visual impression of the size & shape of ion beam, and operational control over diagnostic components like 3-finger probe, Beam Viewer probe, Deflector probe, Faraday cup, X-Y slit, Beam viewer etc. Automation of these components was initially done using customized modules for individual sub-system. An expansion of this facility and various levels of complexity demand modular design to cater easy modification and upgradation. The overall requirements are analysed and modular cards are developed based on basic functionalities like valve operation, probe/ slit/ viewer control, position read-out, interlock, aperture control of beam line and communication. A 32-bit Advanced RISC Machine (ARM) based card with embedded EPICS is chosen as the master controller and FPGA/ microcontroller is used for functional modules. The paper gives a comprehensive description of all modules and their integration with the control system.

THPD13	SocketCAN Device Support for EPICS IOCs	EPICS, controls, status, site	163
	C. Burandt, U. Bonnes, J. Enders, M. Konrad, N. Pietralla TU Darmstadt, Darmstadt, Germany
	Funding: Supported by DFG through CRC 634. A large number of devices used at the S-DALINAC are controlled by IOCs running on standard personal computers via CAN bus (Controller Area Network). CAN interface controllers for PCs are commercially available from different manufacturers but although they all share the same basic functionality, most of them have a vendor-specific API. Moreover, traditional CAN drivers can usually be accessed by only one process at a time which avoids the use of sniffer programs for debugging. In contrast to that the SocketCAN network stack [1], included in recent Linux kernels, provides access to the CAN bus via network devices (BSD sockets) which can be accessed by multiple applications at the same time via a vendor independent interface. A set of open source CAN drivers provides access to controllers of different vendors. This contribution describes an EPICS device support that makes use of the SocketCAN framework and thereby is independent from the API of a specific vendor. The device support has been used successfully in a production environment at the S-DALINAC since almost two years. [1] http://developer.berlios.de/projects/socketcan/

THPD14	Status of the Migration of the S-DALINAC Accelerator Control System to EPICS	controls, EPICS, electron, status	166
	C. Burandt, U. Bonnes, J. Enders, F. Hug, M. Konrad, N. Pietralla TU Darmstadt, Darmstadt, Germany
	Funding: Supported by DFG through CRC 634. The S-DALINAC is a recirculating superconducting electron LINAC which has been in operation for twenty years. The control system had been developed in-house and, while being moderately reliable, has become very hard to maintain and nearly impossible to adapt to new requirements. The replacement of the old analog low-level RF control system by a modern digital solution in 2010 became a primer for the introduction of an EPICS-based control system. Several important subsystems have been migrated since then, but the process has not been completed yet. This contribution overviews the current status of the new control system and developments planned for the future. Basic hardware aspects are described as well as client software and operator interfaces. The general network infrastructure has been restructured in context of the ongoing migration and is also presented.

THPD17	API Manager Implementation and its Use for Indus Accelerator Control	controls, status, power-supply, monitoring	175
	B.N. Merh, R.K. Agrawal, K.G. Barpande, P. Fatnani, C.P. Navathe RRCAT, Indore (M.P.), India
	The control system software needed for operation of Indus accelerators is interfaced to the underlying firmware and hardware of the control system by the Application Programming Interface (API) manager. PVSS-II SCADA is being used at the layer-1 (L1) for control and monitoring of various sub-systems in the three-layered architecture of Indus control system. The layer-2 (L2) consists of VME bus based system. The API manager plays a crucial role in interfacing the L1 and L2 of the control system. It has to interact with both the PVSS database and the L2. It uses the PVSS API, a C++ class library, to access the PVSS database, whereas in order to access the L2, custom functions have been built. Several other custom functionalities have also been implemented. This paper presents the important aspects of the API manager like its implementation, its interface mechanism to the lower layer and features like configurability, reusable classes, multithreading capability etc.

	H.D. Mandaliya, P.V. Edappala, R. Jha, R. Rajpal, M. Shah IPR, Bhat, Gandhinagar, India
	We have developed special instrumentation for spectroscopy diagnostics of the SST-1 Tokamak. Light output in the visible spectrum is guided through fiber optics from the Tokamak ports to the diagnostics Hall, where photo multipliers tubes and other instrumentation electronics are kept. High Voltage(0 - 1500 V) bias generation electronics is required to bias these PMTs. Total 14 PMTs to be biased for overall requirements of the diagnostics. We have developed modular electronics for HV bias generation, which consist of one controller and seven HV modules. We have designed and developed FPGA based controller card which controls seven HV modules. The Slot-0 card is having Spartan 3E FPGA and Standalone Controller Area Networking (CAN) controller. 32-bit RISC processor Microblaze has been deployed into the FPGA. We have used Hitek make HV supply modules which is programmable. In the HV modules, Analog Device Inc. make iCoupler, digital isolators are used to break the ground loops and to avoid ground-lifting problem. Various features like Manual mode/Remote mode operation, HV ON/OFF, HV Value setting through remote GUI have been developed on LabVIEW software.
