DRAFT The FAIR facility will present unique challenges for the ACS which are well beyond the capacity of the existing system. From the very beginning, the design of the ACS has to consider all aspects of the expected functionality needed to operate the FAIR facility. The existing GSI control system will be modernized, with obsolete technology replaced, and will be integrated into the new FAIR control system. The ACS substantially builds on proven principles and solutions of the existing system and is based on a strictly modular design with well defined interfaces. In the design of the system, industrial and widely available commercial hardware and open software components will be used as much as possible. In addition, proven solutions and complete building blocks from other control systems (e.g. collaboration with CERN) will be used in order to reduce development effort. The ACS will be validated and tested already at the existing GSI machines in order to avoid parallel commissioning of a new control system and new FAIR machines. 2.4.A2.1 General System architecture The architecture of the common FAIR accelerator control system is illustrated in Figure 2.4.139. This architecture foresees three tiers: - The Presentation Tier consists of applications for operators and end-users. Typically, these are GUI applications, but can also be web applications or command-line scripting tools. - The Business Tier provides services to the control system. Services are provided both to presentation tier (e.g. name service, archive data) and to the resource tier. The services are responsible for managing almost orthogonal aspects of a control system across the entire facility. All applications reside upon this common layer to befit from the common software infrastructure. - The Resource Tier is closest to the devices that the control system manages. Components of the resource tier map device-specific protocols (e.g. reading/writing of process variables, alarm detection, etc.) to the device-independent protocols standardized across the facility (abstraction). Also, some resource tier components might perform low-level closed-loop control of devices. 160
DRAFT Figure 2.4.139: Architecture of the accelerator control system. The FAIR control system will be implemented as an object-oriented decentralized distributed system. It will be based on a strictly modular design with well defined interfaces. This allows breaking down the project in interconnected work packages that can be implemented independently. 2.4.A2.2 Hardware for Equipment Interfacing The ACS will support several ways of connecting equipment of different types. However, the number of interfaces to the ACS must be kept limited as a large variety of different interfaces cannot be supported and maintained with limited personal resources. At the resource tier, the various actuators, sensors and data acquisition devices are interfaced to the ACS through the following types of front-end controllers: - VME, PCI and emerging PCI-express single board computers are dealing with high-performance real-time processing and data acquisitions. Such systems can employ a large variety of standardized and custom I/O modules (ADC, DAC, binary I/O, Counters, etc.). Typically, the accelerator timing systems, beam diagnostic systems, and interlocks are implemented in this technology. - Most accelerator devices (e.g. all power supplies, rf-systems, kickers, etc.) are interfaced by a dedicated and cost-effective front-end controller (FEC) instead of being connected via a field-bus. This FEC is defined as the “FAIR standard controller”. It is a network node, connected to the timing network (wherever necessary), and provides local CPU-power for real-time control, fast data acquisition as well as any specific functionality needed (e.g. 161
