  This paper describes the alarm system developed at Alba Synchrotron, built on Tango Control System. It describes the tools used for configuration and visualization, its integration in user interfaces and its approach to alarm specification; either assigning discrete Alarm/Warning levels or allowing versatile logic rules in Python. This paper also covers the life cycle of the alarm (triggering, logging, notification, explanation and acknowledge) and the automatic control actions that can be triggered by the alarms.

  In modern scientific instruments like ALBA, ELETTRA or Synchrotron Soleil the monitoring and tuning of thousands of parameters is essential to drive high-performing accelerators and beamlines. To keep tracks of these parameters and to manage easily large volumes of technical data, an archiving service is a key component of a modern control system like Tango [1]. To do so, a high-availability archiving service is provided as a feature of the Tango control system. This archiving service stores data coming from the Tango control system into MySQL [2] or Oracle [3] databases. Tree sub-services are provided: An historical service with an archiving period up to 10 seconds; a short term service providing a few weeks retention with a period up to 100 milliseconds; a snapshot service which takes "pictures" of Tango parameters and can reapply them to the control system on user demand. This paper presents how to obtain a high-performance and scalable service based on our feedback after years of operation. Then, the deployment architecture in the different Tango institutes will be detailed. The paper conclusion is a description of the next steps and incoming features which will be available in the next future.
MOPMN003 A Bottom-up Approach to Automatically Configured Tango Control Systems. 239

  Alba maintains a central repository, so called "Cabling and Controls database" (CCDB), which keeps the inventory of equipment, cables, connections and their configuration and technical specifications. The valuable information kept in this MySQL database enables some tools to automatically create and configure Tango devices and other software components of the control systems of Accelerators, beamlines and laboratories. This paper describes the process involved in this automatic setup.

  Alba is a third generation synchrotron located near Barcelona in Spain. The final commissioning of all accelerators and beamlines started the 8th of March 2011. The Alba control system is based on the middle layer and tools provided by TANGO. It extensively uses the Sardana Framework, including the Taurus graphical toolkit, based on Python and Qt. The control system of Alba is highly distributed. The design choices made five years ago, have been validated during the commissioning. Alba uses extensively Ethernet as a Fieldbus, and combines diskless machines running Tango on Linux and Windows, with specific hardware based in FPGA and fiber optics for fast real time transmissions and synchronizations. B&R PLCs, robust, reliable and cost-effective are widely used in the different components of the machine protection system. In order to match the requirements in terms of speed, these PLCs are sometimes combined with the MRF Timing for the fast interlocks. This paper describes the design, requirements, challenges and the lessons learnt in the installation and commissioning of the control system.

WEPMS024 ALBA High Voltage Splitter - Power Distribution to Ion Pumps 1028

  High Voltage Splitter (HVS) is an equipment designed in Alba that allows a high voltage (HV) distribution (up to +7kV) from one ion pump controller up to eight ion pumps. Using it, the total number of high voltage power supplies needed in Alba's vacuum installation has decreased significantly. The current drawn by each splitter channel is measured independently inside a range from 10nA up to 10mA with 5% accuracy, those measurements are a base for vacuum pressure calculations. A relation, current-pressure depends mostly on the ion pump type, so different tools providing the full calibration flexibility have been implemented. Splitter settings, status and recorded data are accessible over a 10/100 Base-T Ethernet network, none the less a local (manual) control was implemented mostly for service purposes. The device supports also additional functions as a HV cable interlock, pressure interlock output cooperating with the facility's Equipment Protection System (EPS), programmable pressure warnings/alarms and automatic calibration process based on an external current source. This paper describes the project, functionality, implementation, installation and operation as a part of the vacuum system at Alba.

WEPMU005 Personnel Protection, Equipment Protection and Fast Interlock Systems: Three Different Technologies to Provide Protection at Three Different Levels 1055

  The Personnel Safety System is based on PILZ PLCs, SIL3 compatible following the norm IEC 61508. It is independent from other subsystems and relies on a dedicated certification by PILZ first and then by TÜV. The Equipment Protection System uses B&R hardware and comprises more than 50 PLCs and more than 100 distributed I/0 modules installed inside the tunnel. The CPUs of the PLCs are interconnected by a deterministic network, supervising more than 7000 signals. Each Beamline has an independent system. The fast interlocks use the bidirectional fibers of the MRF timing system for distributing the interlocks in the microsecond range. Events are distributed by fiber optics for synchronizing more than 280 elements.

  The control system of Alba is highly distributed from both hardware and software points of view. The hardware infrastructure for the control system includes in the order of 350 racks, 20000 cables and 6200 equipments. More than 150 diskless industrial computers, distributed in the service area and 30 multicore servers in the data center, manage several thousands of process variables. The software is, of course, as distributed as the hardware. It is also a success story of the Tango Collaboration where a complete software infrastructure is available "off the shelf". In addition Tango has been productively complemented with the powerful Sardana framework, a great effort in terms of development, which nowadays, several institutes benefit from. The whole installation has been coordinated from the beginning with a complete cabling and equipment database, where all the equipment, cables, connectors are described and inventoried. The so called "cabling database" is core of the installation. The equipments and cables are defined there. The basic configurations of the hardware like MAC and IP addresses, DNS names, etc. are also gathered in this database, allowing the network communication files and declaration of variables in the PLCs to be created automatically. This paper explains the design and the architecture of the control system, describes the tools and justifies the choices made. Furthermore, it presents and analyzes the figures regarding cost and performances.
