VI Logger data - only hypertrend can display data

Hi,

I am trying to restore data created with VI Logger. I can only display the data with the Active X component HyperTrend. I am wondering why I can't view them with MAX. Because I have lost my vilogger.dat file I can't restore my vi-logger tasks. I have exported the citadel-data to a new citadel database. Now I need to export the data from the Hypertrend to a simple text file. But my problem is that the export feature is only supported in MAX - not in the Hypertrend control.

An example-path in the hypertrend-control is: \\localhost\f__data\\/Waveforms\DB_06\/0x6B7B3F58A518DF75\M1

Has anybody an idea how I can export the data?

Hi Joachim,

If you have the DSC Module from National Instruments, you can try to use the ReadTrace.vi from historical (see Attachement) of this module and get the data to save it to an text file.

Let me know if this work correctly.

Best Regards.

Hi,

Thanks for your reply. I've already tried to get the data with the Read Trace.vi function. The problem is the shared variable name (for example \\localhost\f__data\\/Waveforms\DB_06\/0x6B7B3F58A518DF75\M1). In the meantime I found out that I can get the data with Diadem. In MAX the time-information is lost and therefore I can't view the data directly.

Hi Joachim,

Now you get the data with DIADEM, and are you satisfied with this option or you search about another solution??

I've thought that the recover with Diadem is ok but with another vilogger task (another database) I can't view the data with Diadem. I also can attach the database in MAX but with no values. Isn't there a recovery tool?

Hi Joachim,

Perhaps it's a stupid question but have you try to use the DataReader.vi from the logger exemple??
I think that can help you, don't it?

hi,

I have also a problem with my vilogger.dat. I can only use the DataReader.vi function on a remote computer because only there I have a developer version. I have copied the database data and the vilogger.dat exactly to the same location on the remote computer and used there the rtask command. The task ID of the database I've got from the rtask -dir command. Unfortunately the command rtask -r failed.

Has anybody an hint for me?

Hi,

I think that you have these problems because you lost your vilogger.dat, right?

You can use the SystemRecovering fonction of your computer to restore your computer in the state before you lost your vilogger.dat, that can be a solution, but take care that all what you made for this time (Recover) until yet will be erased.

Best Regards.

Here you find how to export data (take care that's possible but unsupported):

Title:
Can I Transport My VI Logger Data from One Computer to Another?

Problem
I am trying to move all of my VI Logger acquired data from one computer to another. I do not want to export all of the data to text files, but rather to just export all of the data from one installation of the Measurement and Automation Explorer (MAX) and import it all back on another computer using MAX. Can I move the data in this manner?

Solution:
This is unsupported, but possible. You will first need to locate the directory that contains the database information. This is usually located in C:\Program Files\National Instruments\VI Logger\data. If the data is not located there, you can find it by starting MAX and going to Tools»V Logger»Database. The location of the database files should be listed under the location heading.

Once you have located the database, you can copy all of the files located in the database directory to the other computer. They must be copied to the exact same location on the other computer for this to work. After these files have been copied, copy the config.mxs file located in the MAX directory (usually located in C:\Program Files\National Instruments\MAX) to the MAX directory on the other computer. It is important to note that for this procedure to work, you must copy the files to the exact same location on the target computer.

The .mxs file contains the configuration settings for the environment in MAX, so copying this file to another computer overwrites those settings. This may lead to undesired results, and that is why this procedure is not officially supported. It is recommended that this is done on fresh installations of MAX, right before the system has been configured, so that the system can be properly configured once the data is imported.

Note: Make sure you look at the MAX.ini file located in the C:\Program Files\National Instruments\MAX\Data folder to see which is the current configuration file. Normally it should be config.mxs. However, it could be different if there are multiple configuration files located in the folder.

Remember, you have to copy the C:\Program Files\National Instruments\VI Logger\data folder to the target computer to make this all work.
