LV 8.2 DSC Multiple Variable Editor - Import/Export bug?

[andysibley]

Hi,

Has anyone used the export/import feature in the Multiple Variable Editor in LV DSC 8.2?  I'm having problems importing a Comma Separated Variable (CSV) file and it fails to include the "Bind to Source" parameters.

You can test this by simply exporting a bound variable and then importing it into a new library.  Not all the features are imported.

Is this a bug or have I simply not read the documentation or is it not meant to work like this!?

Andy,

Thank you very much for contacting National Instruments. I apologize for the delay in my response. I am currently doing some further checking on this issue. I will get back with you as soon as I have some conclusive information. Thank you very much for your patience.

Rudi,

Apparently this has been identified by Doug Mumford (NI) in an email to our consultant (ThinkG):

"There is a bug in the importing/exporting of CSV files using the Multiple Variable Editor. This will be addressed in the next maintence release of LabVIEW. Attached is a VI that should fix this -- make a backup of the original and replace it with the attached VI. The path to this VI is <labview>\resource\dialog\variable."

See Doug, he'll have the VI.

The bug omitted a ":" e.g. "Network Buffsize" instead of "Network:Buffsize" so that when items were imported back in the items were loaded incorrectly.

I have attached the vi you were referring to in your previous post. Please let me know if this helps.

I tried the attached "SCT Variable to Table" vi, but I still can not get items I exported before.

Rudi,

The fix does work ok.  It correctly exports the SVs and I was able to import them ok.  (Just did a straight export and import into new library.)  I was further able to construct elements to read 2000 tags from the ControlLogix in order to stress-test my system and get some idea of data rates over the network.

Thanks for your assistance in this.

To "Hongling",

Examine the CSV file produced by the Multiple Variable Editor to see if the first line structure is ok and tags, sorry SVs, are correctly listed on line 2 etc.  Try the above export/import into a new library.  I'm sorry to say it worked for me after I replaced the VI with the updated one.

Regards...Andy

Thanks for all information,

I tried again, it worked with new export csv file. Last time I tried to import a previous export csv file, which it did not work.
