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.

236 236  
237 -Few things to consider (in case of doubt talk to the expert (Erland ...)):
260 +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.
238 238  
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.

243 -To choose the desired filesize one has to choose a run mode configuration in the RunControlGUI
