    Opis:
    One of the most important features of the Advanced Telecommunications Computing Architecture (ATCA) contributing to its exceptional reliability and availability is its hot-swap functionality. In order for the user to be able to add and remove the components of an ATCA shelf without the necessity of switching the power on and off the PCI Industrial Computer Manufacturers Group (PICMG) specification clearly enumerates the stages a Field Replaceable Unit (FRU) has to go through upon insertion into and extraction from the shelf. These stages form the activation and deactivation processes that occur every time an element is changed in the ATCA system. This paper focuses on these processes placing the emphasis on the Electronic Keying (EK) implementation in the Intelligent Platform Management Controller (IPMC) software developed for the self-designed ATCA Carrier Board (CB). This CB is considered to be used in the Low Level RF (LLRF) control system of the X-Ray Free Electron Laser (XFEL). It utilizes the standard-defined PCI Express (PCIe) interface as well as introduces proprietary protocols in form of Low Latency Links (LLL).

    Opis:
    Modern Advanced/Micro Telecommunications Computing Architecture (ATCA/žTCA) standards gain popularity, not only in telecommunication industry, but also in High Energy Physics (HEP) area. These platforms are considered as the future platform for the Low Level RF (LLRF) control system of the X-ray Free Electron Laser (XFEL) project realized at Deutsches Elektronen-Synchrotron (DESY) facility. One of the most important features of an ATCA/žTCA based control system is its high reliability, which can be decreased by negative influence of neutron and gamma radiation produced during normal operation of linear accelerators. The XFEL laser will be built in a single tunnel to decrease costs of the project. Therefore, the LLRF system will be exposed to harmful radiation. It is recommended to monitor doses absorbed by electronic equipment. The gathered data could help to estimate lifetime of electronic devices and to schedule essential equipment replacement. The radiation detector should be integrated with the ATCA/žTCA system to allow measurements in close proximity to the electronisc, which helps to increase the accuracy of measurements. The paper describes a radiation monitoring module capable of monitoring gamma radiation and neutron fluence in real-time which fulfills the mentioned requirements and is designed in accordance with the AMC specification.

    Opis:
    The Advanced Telecommunications Computing Architecture (ATCA) standard describes a powerful, high performance platform. Its implementation has been considered among candidates for a base of the control system of the X-ray Free Electron Laser (X-FEL), which is being built at Deutsches Electronen-Synchrotron (DESY) in Hamburg, Germany. The Low Level Radio Frequency (LLRF) control system is designed as a set of ATCA Carrier Boards. Each Carrier Board hosts an Intelligent Platform Management Controller (IPMC), which is developed in compliance with the PICMG specifications. IPMC is responsible for management and monitoring of components installed on Carrier Boards and pluggable Advanced Mezzanine Card (AMC) modules. The ATCA Shelf Manager is the main control unit of a single ATCA shelf, responsible for power management, fan modules and Carrier Boards installed in ATCA shelf. It provides a set of control and diagnostic capabilities regarding the shelf and its sub-modules. These capabilities are available for operators and can be used by higher level applications. This publication presents a software component intended to support management and supervision of the ATCA shelf and its sub-modules, including Carrier Boards with AMC modules. The application provides enhanced mechanisms of control and allows to acquire detailed information regarding status and parameters of crucial devices (e.g. power supply voltages, temperatures, presence of reference clocks). The information supplied from Shelf Manager combined with graphical user interface of the application provides visual representation of selected system components and contributes towards efficient control and supervision of Carrier Boards and entire ATCA-based platform.

    Opis:
    The Advanced Telecommunications Computing Architecture (ATCA) specification allows to meet the newest trends in high speed communication technologies. Furthermore, it provides manageability, availability and exceptional reliability at 99.999% level. Therefore, this architecture is perfect to use in control systems of complex projects like the Free-Electron Laser in Hamburg (FLASH) or the X-ray Free Electron Laser (X-FEL) that work with high-frequency signal processing, use high-speed communication protocols such as PCIe, Gigabit Ethernet or RocketIO and require continuous stable operation. Modular construction allows for flexible system configuration. What is worth emphasizing, in contrast to previous solutions like, VME (Versa Module Eurocard), it is possible to change the system configuration without the need for power shutdown. Hot-plug functionality is delivered by Intelligent Platform Management Interface (IPMI) system. For this reason, all ATCA units, which can be replaced in the field should have Intelligent Platform Management Controller (IPMC) that provides IPMI functionality. The IPMC is responsible for management and control of module on which it is placed. Due to the fact that the IPMC operates independently of another components, it allows to activation and deactivation other functional blocks of the module. For this purpose if has to communicate with the Shelf Manager according to IPMI standard. The IPMC monitors also vital operational parameters such as temperature, voltage, current and reports all abnormalities to the Shelf Manager. This paper presents the IPMC for ATCA Carrier Board with three AMC Bays. All IPMC functionalities required by ATCA specification are in this case fulfilled by microcontroller dedicated for IPMI management in xTCA systems.

    Opis:
    As a result of a growing interest in the xTCA systems by research centers conducting High Energy Physics (HEP) experiments, the PICMG xTCA for Physics Coordinating Committee is developing a new, attractive standards. They are specifically dedicated to control and data acquisition systems of HEP applications. These new specifications define a number of extensions to the Advanced Telecommunications Computing Architecture (ATCA) and Micro Telecommunications Computing Architecture ( μ TCA) standards. The MicroTCA for Physics specification, named MTCA.4, defines some new solutions in order to simplify an application of μ TCA specification in HEP facilities. The most important of them is μ RTM module which can be connected to the Advanced Mezzanine Card (AMC) and provides more usable area and additional I/O connectors at the rear of the shelf. The MTCA.4 also introduces additional channels dedicated for timing and synchronization signals that are available on backplane. Due to the fact that xTCA for Physics is a new specification which has not been officially published, both the AMC and μ RTM modules and the software for the MMC with possibility of μ RTM handling are not yet available. For this reason the preparation of firmware for the Module Management Controller (MMC) for AMC modules compatible with MicroTCA for Physics specification is required. This paper presents a structure of the MMC for the μ TC (MicroTCA-based Controller) board. It also describes the microcontroller software which fulfills the role of the MMC.

    Opis:
    The Advanced Telecommunications Computing Architecture (ATCA) standard describes a powerful and efficient platform. With multiple integrated solutions like redundancies and intelligent control mechanisms this technology is characterized with reliability estimated at the level of 99.99999 percent. These features make the standard perfect for use in projects like the Free Electron Laser in Hamburg (FLASH) and the X-ray Free Electron Laser (X-FEL) in order to help them meet the requirements of high availability and reliability. The ATCA standard incorporates advanced control systems defined in the Intelligent Platform Management Interface (IPMI) specification as one of the key elements. The entire ATCA implementation retains its functionality as long as the IPMI remains operational. The complexity level of the application increases, which results in preparing it to run and debugging being more difficult to perform. At the same time, only scrupulous elimination of any kind of possible deficiencies can enable the ATCA implementation to offer the desired level of reliability. Thus, diagnostics become crucial, which creates a need for additional tools performing these tasks during the preparations of both hardware and software for the ATCA application. The paper presents application aiding in development of the prototype Carrier Board by enabling the user of external PC station to perform diagnostic and control activities over the Board. It helps in examining all its components at the stage of running the Board, as well as in further operation analysis.
