Import Existing Module

Hello,

I have several signal characterizer function block curves to update.  I have the new values in a spreadsheet, but I do not see a method for importing the values.  As a test, I wanted to see if I could export the module to an FHX file, change the file, and then import.  In DeltaV Explorer, I selected the module, then clicked File > Export > Selected Object...  I selected a folder and clicked Save.  In a text editor, I changed a couple of the curve values in the FHX file, saved, and closed the text editor.  Back in DeltaV Explorer, I made sure I selected the module that I had just exported, then clicked File > Import > Standard DeltaV Format...  I selected the FHX, made sure "Include the license information" was checked, then clicked Open.  We use version control, so I clicked "Yes" to automatically check out modules as necessary.  The import dialog indicates that "the entire import content has been skipped with no update to the database".  When I open the module in Control Studio, the values that I changed in the FHX file are not changed, so it truly did not import.

I read this topic, and there is mention of being prompted for duplicate items when importing, but I have a feeling that pertains to database imports within Database Administration, and not the import utility within DeltaV Explorer.

Anyway, I was wondering how to import an existing module?  Alternatively, is there a method to updating the curves in a signal characterizer function block, besides doing it one item at a time in Control Studio?

We are using DeltaV Explorer v 14.3.1 Build 7288.

    The import function checks to see if the object's time stamp has changed. If the item time stamp is identical to that in the database, it skips the item (module, composite) as it cannot possibly be different. When editing an FHX like this, you have to either alter the time stamp in the FHX, or you can edit the Module to be imported, so that the database assigns a new time stamp. This will allow the FHX to import.

    If you edit the curve through the HMI, then you can upload the changes into the database.

    A bulk import for the curve would be useful. I have not looked at whether this is doable. I have a spreadsheet for updating SGCR curves in run time. Since I manipulate the curves via OPCDA, the server does not record an upload record for the changes. I did a quick look but I cannot find where to turn on the OPC DA upload records. I'm not sure if this option only enables Event Chronicle records of changes by the OPC Server or if Upload records are also done. But I can't find where to enable this anyway.

    If I get a chance, I'll look at creating the Bulk import file for the array. That would be the best way to move data into the database without editing FHX files.
