The cryogenic installations on the DESY campus are widely distributed. The liquid Helium (LHE) is produced in a central building. Three cryogenic plants are installed. One is in operation for FLASH the other two are currently in the commissioning phase and will be used for the European XFEL. Thousands of I/O channels are spread over the campus this way. The majority of the I/O devices are standard devices used in process control. The de facto standard for distributed I/O in process controls in Germany is Profibus. So it is obvious to use this bus also for cryogenic controls. Subsequently we developed also special electronics to attach temperature and level readouts to this field bus. Special diagnostic tools are available and permanently attached to the bus. Condition monitoring tools provide diagnostics which enable preventative maintenance planning. Specific tools were developed in Control System Studio (CSS) which is -the- standard tool for configuration, diagnostic and controls for all cryogenic plants. We will describe our experience over the last years with this infrastructure.

The cryogenic systems at DESY are controlled by the process control system EPICS. New cryogenic plants and new test facilities for the European XFEL are currently beginning their routine operations. Other components of the XFEL are under construction or currently in the commissioning phase. Diagnostic analysis of events in the system is getting more difficult due to the complex environment. Current post mortem analysis is typically carried out by retrieving archived data and plotting the results in a trend plot. The disadvantage of this approach is that you only see those channels which are configured as potential candidates for a good analysis. Channels which might actually explain the root cause of the event stay out of sight. We have developed mechanisms to play back the archived data directly into the data stream of the operator console. This way the data get displayed into the synoptic displays in the same manner the operator is used to. This way the analysis of events is eased. Within a given time period it is possible to run forward or backward with a time-slider. First results will be shown.
The work is carried out as a master thesis at the university of Hamburg.
