Hi Thais Christina,

It sounds like you want to convert existing TDMS data files into some sort of RPC file, is that correct?  Is the DataPlugin you said you downloaded from the NI website the "RPC III" DataPlugin?  If both of those interpretations of your post are correct, then I can explain the problem-- the "RPC III" DataPlugin is read-only, so it can not be used to create an "RPC" data file.

Or were you wanting to load an existing RPC data file and save it into TDMS format?  That should work.  In that case, what exactly is the problem you are encountering?  What have you tried so far?

Please specify more exactly what you need,

Hi Brad Turpin,

Actually I did download a DataPlugin RPCIII for reading data in Diadem.
However I used the version Diadem10 and with it we could read and write in the format RPCIII. In the current version Diadem11, after the download of the DataPlugin, I can not write to the PRC format, only reads.

So I need the version Diadem11 reads and write in the format RPCIII, and possible?

Hi Thais Christina,

OK, yes we can get that behavior in all versions of DIAdem.  What you're referring to is functionality from a so-called "GPI DLL", of which about a dozen install with DIAdem.  DIAdem used to automatically register many of those GPI DLLs, but now you need to explicitly register the GPI DLL you want yourself.  You also need to save that configuration change to your Desktop.DDD file (DIAdem's initialization file) in order for the registration change to still be active each time you start DIAdem thereafter.

1)  Choose the DIAdem menu "Settings >> Options >> Extensions >> GPI Extensions..."

2)  Click on the <Add> button in the "GPI Extensions" dialog that pops up

3)  Select the file "GfSRpc3.dll" from the file browser and click on the <Open> button

4)  Click on the <Close> button in the "GPI Extensions" dialog

5)  Click onn the <Yes> button in the "DIAdem" dialog that pops up

6)  Take the default "Desktop.DDD" file and click on the <Save> button in the new dialog

7)  Click on the <Yes> button to confirm overwriting the Desktop.DDD file

😎  DIAdem will now shut down automatically and restart with the RPCIII functionality

9)  Choose the NAVIGATOR menu "File >> Save As..." to test the RPCIII functionality

10) Change the "Save as type" field to "RPC3-Files (*.rsp)" in the "Save As" dialog

11) Click on the "Save" button in the "Save As" dialog

12) Select the time base or time channel number in the final dialog

Hi Brad Turpin,

Thanks for RPC suport.

Now I have new question: the same procedure to export in TDF format by LMS don't work. can you help-me?

Hi Thais,

My experience with LMS has been that their file formats are designed to be closed to non-LMS applications.  Is this TDF file format an open file format?  Is there a document you can point us to that describes the file format and how to load it?  Is there a posted API that one can download for free and use to read/write data from/to a TDF file?

I am not aware of any capability DIAdem has to either read or write TDF data files, am I missing something that you're aware of?
