HP34401A output Data to float

Currently using HP34401A driver and use the example code to display the result of the reading.
Data Type declaration of the variables according to the sample
ViReal64 reading;
ViChar msgStr[256];
checkErr( hp34401a_Read (hp34401a, 5000, &reading));
sprintf (msgStr, "%f", reading);
so for it to display on the panel, i created
SetCtrlVal(panel,PANEL_STRING, msgStr);
not it shows the reading on the Panel as a string(correct me if I am wrong),
because I want to do a calculation first on the reading like I want to display it on float, how can i convert it as such, something like
floatvariable = reading/somevalue;
SetCtrlVal(panel,PANEL_STRING, floatvariable);
thanks
edit: can someone move this to Labwindows/CVI Area?

How do I make a VI that contols a 6534 card take less time to load 1Mbyte and output data ?

Hello-
I'm developing a pattern generation burst mode type VI that reads byte characters from a text file, manipulates the bytes that it reads and then outputs the data from a 6534 card. The REQ1 pin is pulled high which makes the card continually output data until the internal buffer is empty. An internal clock is used. The problem is that the size of the file that is read by the VI can be relatively large, in the 1MByte range. After the VI manipulation, the output array is 16 times larger than the input string. So, when the VI reads a 1MByte text file, the output array contains 16 million entries (each array entry is 3 bits by the way). It takes about 20 seco
nds to run and output data from the 6534 even when reading files that are 200kbyte or so. I'm outputting the data at 5Mbps. I'm not sure where all the delay is coming from. Using the 'Profile VI" function under the 'Tools' menu shows a snapshot of time that really doesn't help me since it only shows that the time is spent in my VI. Is this just the result of loading large files ? Or, is there a way to preload the 1MByte file into the 32MB of RAM on the 6534 card before the VI is actually run. What I mean is that I do have the option in my system to have a time when all text files will somehow be loaded into the 6534 memory, during some initialization period, and then the VI would be run with the text file already loaded. This of course assumes that the delay is loading the file from the harddrive, but since the harddrive transfer speed is fast, I have no idea where to speed things up. Any ideas ? Thanks !

Your question actually belongs to the Measurement Devices >> Digital IO section since it concerns operating the 653x family of digital boards. You will see other related questions and answers there. In the future, please direct your digital questions to that forum.
If you are trying to profile your VI, you can break it into different pieces. For instance, you can make a subVI out of the file data manipulation.
Now, are you doing pattern generation or burst mode handshaking output? From your description of the signal connections, it looks like burst mode. You can double-check in the 653x User Manual at the http://www.ni.com/manuals pages. Still, it looks like you could accomplish your task with pattern generation. There are example VIs for both operations that
I suggest you start with. They are located in the LabVIEW >> Examples >> Daq >> Digital >> 653x.llb directory.
It also sounds like you are doing a single buffered operation, where you have a set amount of data that you want to output, and once done, the VI will stop. You are preloading the data to the buffer at DIO Write.vi before the 6534 actually outputs the data with DIO Start.vi when you program like the examples.
Thus, start with the appropriate example and then add the File I/O to it. You can even test with a smaller file to see the effects. You will also find useful information concerning the 6534 in the KnowledgeBase, particularly KnowledgeBase 298CGF9M "How Many Samples of Data Can I Store in the Onboard Memory of the NI 6534?". You can find this online by going to the http://www.ni.com/support and choosing KnowledgeBase from the Technical Resources pull-down menu. Then, type in keywords to search for, such as "6534".

How can I convert output data (string?) from GPIB-read to an 1D array?

Hello all,
I am reading a displayed waveform from my Tektronix Oscilloscope (TDS3032) via the GPIB Read VI. The format of the waveform data is: positive integer data-point representation with the most significant byte transferred first (2 bytes per data point).
The output data of GPIB-Read looks like a string(?) where the integer numbers and a sign like the euro-currency sign are seperated by spaces e.g. #5200004C3 4 4 4 4 3C3C3........ (C represents the euro-currency sign).
How can I convert this waveform data into a 1D/2D array of real double floatingpoint numbers (DBL) so I can handle the waveform data for data-analysis?
It would be very nice if someone know the solution for this.
t
hanks

Hi,
First of all, I'm assuming you are using LabVIEW.
The first you need to do is parse the string returned by the instrument. In this case you need to search for the known symbols in the string (like the euro sign) and chop the string to get the numeric strings. Here are some examples on parsing from www.ni.com:
Keyword Search: parsing
Once you parse the numeric strings you can use the "String/number conversion VIs" in the String pallette.
Hope this helps.

Output data to txt file with full length of the field as in database

Hi
I have a problem related to output data I ntxt file on server
for eg
CONCATENATE
wa_sagadr_outtab-seqno
wa_sagadr_outtab-bpext
wa_sagadr_outtab-name_org1
wa_sagadr_outtab-country INTO wa_sagadr_text SEPARATED BY ''.
the output is separated by single space irrespective of database length of the field , I want to display all the lenth of the database field eventhough the remaining space is blank ie if a field is 20 char in dtabase and only filled with 6 char the whole 20 char lenth should be displayed in the output file
ouput as below
required format ie space equvalent to as in database lenght
000001       700006               C4 Plant AMD Export Sdn.Bhd.so on.
my format as coming single space in between only
000001 700006 C4 Plant AMD Export Sdn.Bhd
pls suggest

For this maintain an work area with the fields and structure same as the one which you want.
ten populate the work are and write to file.
concatenate will not work.
e.g.
DATA: begin of wa_sagadr_text,
          seqno like wa_sagadr_outtab-seqno,
          bpext like wa_sagadr_outtab-bpext,
          name_org1 like wa_sagadr_outtab-name_org1,
          country like wa_sagadr_outtab-country
          end of wa_sagadr_text,
clear wa_sagadr_text.
wa_sagadr_text-seqno = wa_sagadr_outtab-seqno.
wa_sagadr_text-bpext= wa_sagadr_outtab-bpext.
wa_sagadr_text-name_org1 = wa_sagadr_outtab-name_org1.
wa_sagadr_text-country = wa_sagadr_outtab-country INTO wa_sagadr_text.
transfer wa_sagadr_text to outputfile
or write:/ your fields.

How to output data to a file in SCC-SG04?

I am using SCC-2345 with SCC-SG04 connected to NI-6221 in Windows 2000 in VC6.
How to output data to a file like data1.dat in VC6 or in Labwindows/CVI?

Hello mwibm,
If you just want to do file input/output in LabWindows/CVI, I would take a look at the Formatting and I/O CVI library or the ANSI File I/O functions. For example, if you just want to write an array of data to a file, I would look at the ArrayToFile function or the fwrite/fputs/fprintf ANSI C functions included in stdio.h. The ANSI C functions will also work in Visual Studio. More information on the LabWindows/CVI File I/O functions can be found in CVI help, and more information on ANSI C functions can be found in CVI Help and online at various websites.
Maybe you could further clarify what problems you are having and what kind of data you want to write to a file.
Thanks.

      But, Here the report consists 3 alv outputs. when double clicking function happens, it will direct to another alv output.
    Those, all the outputs of report i want to get into z-program.
PLease , give reply as early as possible.
Thank u in advance,

HI,
When i download,only one output i will get.
But,if i double-click the particular record it will show another output. I want that output also.
Like that,when i double-click particular record, it will show some other alv ouput based on record,
i wanted all those outputs.
If i copy the code, whether i face any problems?

Filter output data according to portal current user name in omni portlet

We have created an omniportlet that connects to a database, and retrives some values into a defined HTML layout.
We want to filter output data according to our portal current user name
When we try to use portal.wwctx_api.get_user inside of omni portlet select statement fallowing error occurs.
Error in executing Query : [ORA-06510: PL/SQL: unhandled user-defined exception ORA-06512: at "PORTAL.WWCTX_SSO", line 1803 ORA-06510: PL/SQL: unhandled user-defined exception ORA-06512: at "PORTAL.WWCTX_SSO", line 1637 ORA-06502: PL/SQL: numeric or value error ORA-06512: at "PORTAL.WWCTX_SSO", line 1865 ORA-06512: at "PORTAL.WWCTX_API", line 183 ]
Thanks a lot

hello
i think you cannot use the portal built-in packages inside omni portlets. Omni portlets is designed to connect to other data source (not only oracle) and Portal API might not be available at these data sources. Therefore, you should not be using these Packages at all!. i tried very hard, but to no avail.. Omni portlet has its own repository!! if you cannot pass the infomration as a parameter, then find a different approach

This is because the Omniportlet is actually operating within a different context--a separate database connection from the Portal connection. We have similar issues with Java portlets. You might try creating a public parameter on the portlet, then mapping that to the system variable USER (done on the Parameters tab of the page where you deploy it--if you don't see a parameters tab, you must enable Parameters and Events at the page group properties level). I haven't tested any of this, but it should get you going in the right direction.

How to output data outtside a for loop every 10 iterations?

Hi friends,
does any body help me to sort out this problem?
please check the attchement for my vi.
all i want is output data from inside for loop to outside for loop every 10 iterations. please do not use local variable.
Many thanks

Hi Dan,
I am not sure what you want to do every 10 iterations with the value outside, but If you want to update your graph every 10 iterations use the following way:
If you want to handle the specific value every x iterations outside the loop you could either use queues or notifieres.

Hi,
You can store the Query output data into DSO through the APD process.

How to handle Output Data Association when no row returned?

In BPM 11g, I'm using a Service to select a row from an external database passing a parameter using a Database Adapter. Works fine when a row is returned. But if no row is returned (which can happen because no match is found on the Select based on the parameter value), I'm getting an error on the composite because the Output Data Association has the return values, including integers, mapped to a Data Object I defined in the process. Well if no row is found, the integer value is empty, and errors out trying to save it.
How do I handle this situation?
The specific message is this:
The expression bpmn:getDataOutput('wm91AInterfaceMainCollection')/ns:Wm91AInterfaceMain[1]/ns:board is empty. An attempt to read or copy data referenced or computed by the XPath expression either had invalid data, according to the XML schema, or did not contain certain optional data. Ensure that the variable or expression result named in the error message is not empty. Enable XML schema validation of related data elements to ensure the run-time data is valid.
I must be missing something obvious here, but cannot find a way to handle this. Thanks in advance!

Dan - Never mind about my request for an example. I figured it out. My problem was that the destination variable was a primitive process variable of type Integer, thus not allowing the creation of an XSLT. Once I created a Complex process data object containing that Integer, I could create an XSLT with an If statement. Thanks again.
