Current Value Table (CVT)

[chrisosw]

I have some errors in the wiring scheme. The Type-Definition FileFormat.ctl has no Field "Group Listings" which I need for Create 'Tags.vi, in this way it's not running. And the TypeDefinition CCC-Tag-config.ctl has no field direction - but I get no error, I don't know how important it is.

Does someone knows what I can doing.

Thanks,

Christian

I'm not sure I understand the problem. Could you take a few screenshots to better illustrate the point?

Hello,

(happy new year)

I have build a test VI and get the error from the unbundle by name vi.

Hey Christian,

It just looks like you just need to change the indicator on the top right side into a constant, then you should be able to populate the cluster.

Thanks,

Oh yes thats correct, but also in this case the CreateTags.vi don't work, because there is no "group listing" in the unbundle by name from the CVT-Tags input".

Is there a special format of the tag-list.csv?

Thanks

It looks like something modified that cluster on disk. Try using VI package manager to reinstall CVT.

The reinstallation gives the same cluster. On the disk (LabView 2011:vi.lib:NI:Current Value Table:TypeDefs:File Format.ctl) has the same content and gives the same error. Where can I found the correct cluster with the Group Listings?

When I open the file you attached, I see group clusters show up. Try the following:

1. Open the create function and try to change the unbundle to access the value. Sometimes if an element gets removed and added back, the unbundle nodes will not be linked to the correct data.

2. If that doesn't work, close LabVIEW entirely, uninstall CVT, and reinstall from the tools network. Make sure you are installing 3.3.0.13 (vipm://ni_lib_cvt?repo_url=http://ftp.ni.com/evaluation/labview/lvtn/vipm). If you left anything open last time you uninstalled VIPM may not have been able to reinstall correctly.

3. Worst case scenario, you can go to this location C:\ProgramData\JKI\VIPM\cache and look for the file "ni_lib_cvt-3.3.0.13.vip". Rename this file to ni_lib_cvt-3.3.0.13.zip (VIP files are actually zip files) and extract it on disk.  Then copy the files in ni_lib_cvt-3.3.0.13.zip\File Group 0\ to your LabVIEW directory, overwriting any files that are there. This is basically what the install does.

Thanks,

Daniel

Ok, after reinstallation it works.

Thank you

I have another question for this scheme. From the vi "Scan from string" I get an error - "scan failed,  input string does not contain the information expected by the Scan String". What is the correct scan string for this table?

Thanks
