233 +The DAQ writes into a file (in .raw format) up to a configurable value. If the limit is reached the file will be closed and a new file will be started. Thus a run can contain tens to hundreds of files.
238 238  
239 -=== Assigning the DAQ to the beamline in jddd ===
235 +The size can be configured to be 100 MB, 350 MB or 1000 MB (default)

241 -To assign which DAQ is used at what beamline one has to use the dropdown menu in the {{code language="none"}}parameter monitor{{/code}}. In each Beamline overview tab (BL1,2,3) there is a button (upper right) that starts the {{code language="none"}}parameter monitor{{/code}} panel. In the upper middle is a DAQ field in which the appropriate DAQ can be assigned to the Beamline.
237 +Few things to consider (in case of doubt talk to the expert (Erland ...)):
242 242  
239 +* 1000 MB: This is the standard setting which is best for archiving (few large files are preferred). However mainly for images that are saved with less than 10 Hz the HDF5 converter has problems with the large files. And for low data rates it may take upto half an hour to fill one 1GB file. Then smaller ones are also preferable.
240 +* 350 MB: Often a good compromise ...
241 +* 100 MB: It is not preferred to have many "small" files for storing the data. For very small data rates this is an option to not wait too long till the next file is created.
242 +
243 +To choose the desired filesize one has to choose a run mode configuration in the RunControlGUI

387 +=== Re-read the data base ===
388 +
389 +If there are new Properties included by Vladimir et al one has to reread the data base.
390 +
391 +This can be done easiest by going to the run modes and choose a different "stored setting" (changing e.g. from filesize 100 MB to 350 MB) and going back to subsystems. At this point the new database entries are read in. then one can do the same backwards to switch back to the initial file size. Doing this the configured list of subsystems is lost and one has to reload the whitelist and start a run to get the loaded whitelist in the configuration.
