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.
