If I set number of records to 255 in DataLogCreate block, the system create's the csv file and datalogger is working. If I set number of records more then 255 (I want't 3000 samples) the system does not create the csv file. Why is this? Best regards

Best regards Your strings, are they the default string length (255) or have they been reduced to a realistic size to hold the max content size? @ 255 records with the default string length, that is 1.3 MB per dataset. Are you removing the old dataset before creating a new dataset at the larger size? What error is returned for the create instruction when it fails?
