Data missing in datalog type files when logging on Compact field point

Hi,

 

I have a datalogging application running on CFP 2220 which logs data every 10sec to a *.dat file continuously for 2days. The logging method is as follows:

 

1. Open *.dat file connection once in the beginning of the application.

2. log data continuously to the file every 10 secs 

3. Close connection when the application is stopped.

 

Data fields logged to the file are : Datetime, SensorName, Sensorvalue1, Sensorvalue2, SensorErrordetail.

 

The problem I am facing is that, when I try to read the data in Labview (on PC) from the *.dat file then it contains valid data only for approx. 1 day and the data for other days is not logged to the file but instead there are empty fields displayed. Also when I checked the file last update datetime I could see thats its latest and updated..

 

Can someone please help me to figure out the possibilty of the problem.  

 

Thanks,

Alifiya
