Hello All,
I have found DataPlugins which read a variety of binary files that Hioki devices create, in particular ASCII and HiCORDER files. I was wondering if a DataPlugin exist or could one be made to read the *.IVT “Time Plot Data File” extension which Hioki Power Quality Analyzer such as Model 3193, 3196 and 3197 creates.
With Dataplugins, after installation could I just load the associated files into Labview or must I load them into DIAdem? I have tried to use the HIOKI_ASCII DataPlugin unsuccessfully. I have installed the DataPlugin.

Hi Fro,
You can use all DataPlugins in LabVIEW, DIAdem, and the DataFinder. In order to use the DataPlugin in LabVIEW, you need to use the Storage VIs with a special "Open with Store.vi" that ships with LabVIEW but is not on the palette. There are examples of this that you can download and use directly from the www.ni.com/dataplugins web site:
http://zone.ni.com/devzone/cda/epd/p/id/4181
For these examples, you need to know the correct programming name of the DataPlugin to use-- typically this is the same as the name of the DataPlugin listed at www.ni.com/dataplugins. You can find the programming name of the DataPlugin for sure in the DataPlugin dialog in DIAdem, if you have doubts.
I will forward your request for additional Hioki DataPlugins on to R&D,

Being that I currently do not have DIAdem installed. Is there a way to verify the DataPlugin name via Labview?
The example code is interesting I am still having trouble getting it to work but I will figure it out, espcially if the name of the plugin is wrong. There is no error prompt to tell you this.
What about my request for the *.ivt file extension?

Hi Fro,
I installed that DataPlugin and looked in the DIAdem DataPlugins dialog for you-- the programming name is "HIOKI_ASCII". If you continue to have difficulty reading your data files into LabVIEW with the example program and this DataPlugin name, please post an example file, and I will take a look at it.
Regarding the *.IVT DataPlugin request, as I mentioned, I forwarded that on to R&D. Normally customers make requests at the bottom of the www.ni.com/datplugins web site, which has the advantage that a support engineer doesn't have to manually ferry the request to R&D. I just heard back from R&D on this request, and they requested that you send in several example data files for them to assess the level of difficulty to create the DataPlugin. If the file is an ASCII file, this is all they need. If the file is a binary file, you will also need to provide us with a detailed file format description, probably from Hioki.
If the DataPlugin turns out to be pretty simple, R&D will probably just create it themselves with no further ado. If it turns out to be hard, your options are then to program it yourself, hire an Alliace Member to program it for you, or put pressure on your local NI sales engineer to convince us to write it for you anyway. Hopefully it will be simple.

Thank you for your prompt reply. I am currently in contact with Hioki to ask about the binary file format. Upon receipt of their reply I will forward it to you and also post some example code.
Thanks,

Attached ye shall find an example ITV file. I could not upload a *.IVT extension so I changed it to a *.TXT note it is not a text file. Hopefully this wll help. I am not able to get a detailed file format description from Hioki.

Hi Fro,
I downloaded your posted IVT file. The only information that is human readable is the following:
"This is HIOKI 3196 TIME_PLOT DATA FILE"
The rest of the file is a binary black box of bits. There's no way to decode it without some clues as to how the information is stored.

Hioki themselves has contacted me and said they will get me the detail description providing I sign a non disclosure agreement. If this is done I guess I would have to make the DataPlugin myself. Me creating a DataPlugin….. I have never even successfully used a DataPlugin. But I guess I will try.
Thanks for all your help again….
