rename historical data

[Paolo_Squillari]

I'm using LabVIEW DSC 7.1. I'd like to rename traces in my Citadel database. By default trace's name is: \\<computername>\<databasename>\<tagname>. I'd like to rename to tagname only.

So for example: \\pc1\db\dummy_IO I'd like to rename as dummy_IO. One possible solution is to rename it using HDV (Historical Data Viewer). I'd like to know if it is possible to rename a trace (or a group of traces) programmatically. I've already tried to use the: rename historical data.vi, but without success. I got only errors. Is there somebody who knows how to use the rename vi?

Thank you,

Paolo.

Hi, I don't think that it is possible because citadel needs to save also the URL to preserve his network functionality. In attach I send you an image of a diagram that shows how you can use the "Rename historical Data.vi". Best ragrds AmbuA

It is not possible to modify a Citadel trace URL to be shorter than three elements. The first two URL elements are required by the internal organization scheme of the database. If you are not actively logging data, you are free to rename the first two URL elements to whatever you like. The first element does not need to be a machine name, for example. Newly logged data will always use the \\machine\process\tag format, however.
