Control System Interoperability, an Extreme Case: Merging DOOCS and TINE

In controlling large facilities one is rarely able to manage all controllable elements via a common control system framework. When the standard framework must deal with numerous 'foreign' elements it is often worthwhile to adopt a new framework, rather than 'disguising' such components with a wrapper. The DOOCS[1] and TINE[2] control system frameworks fall into this scenario. Both systems have a device server oriented view, which made early mapping attempts (~2001) immediately successful. Transparent communication, however, is but a small (albeit important) part of the control system merger currently taking place. Both systems have well-established central services (e.g. archiving and alarms), and possess a general 'culture' which might dictate to a large extent how something is actually 'done'. The long term goal of the DOOCS/TINE merger is to be able to make use of any tool, from either the DOOCS or TINE toolbox, on any control system element. We report here on our progress to date, concentrating on the REGAE accelerator, and plans for the XFEL accelerator (to begin commissioning in 2015).

Controls Architecture for the Diagnostic Devices at the European XFEL

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.
