Can I parse an ASCII charater variable that is included in the data string from my device?

Here is the RS232 data from the device.
“R,2.306 MPa a,0.011 MPa/s,97.000 kPa a”
OR
“NR,2.306 MPa a,0.011 MPa/s,97.000 kPa a”
Channels 0,1, and 2 take care of the 3 numerical values and write them to a file no prob..
The R and NR represent the Ready Status of the device, is there a way to write these characters into the same file?
Any help is appreciated, I'm fairly green when it comes to DASYLab.

Here are a couple screen shots of trying to read just the one channel using the a\x2c measurement data format.
As shown in the RS232 monitor, it looks like its ignoring the text characters i need, and picking up the values that are already being written to a file in my original worksheet.
I also messed around with your suggestion to store it as a global string and use the action module to write it to my txt file. I'm not too sure I was doing this correctly, how are the RS232 Input, action, and write modules linked to each other in order to get this accomplished?
I was able to write the string to the header of my file, but thats just a one-time write..
Thanks for your reply cj

How can i use an ao card (pci 6723) to output data and to trigger an ai o acquire the data coming from the ao card?card (pci 6254) t

Hello
I am trying to perform AO (pci 6723) and to trigger my AO card (pci
6254) to read the data coming from the AO card. I am using LV7,1,
win2000.
Is an RTSI cable necessary or I can connect the trigger signals externally ?
I am using the LV example " multi function - synch ai-ao.vi" but i can't for some reason configure the trigger lines.
thank you in advance for your time.
Yiannis

Hello Yiannis,
If I understand you correctly, you want to synchronize your analog input and analog output that are started by a trigger on the analog input board. If you don't want to use the RTSI lines, your best bet is to export the AI Sample Clock and then read it in to the AO board. There is an example on ni.com called DAQmx - Synchronized AIAO Shared Clock. It appears to be having techincal issues so I have attached the example below. To export ai/sampleclock, use DAQmx Export Signal.vi after Get Terminal Name with Device Prefix.vi. Export Sample Clock to PFI3 (There are only connections between the sample clock and PCI3/4/8/9). Connect PFI3 on your AI board to PFI0 on your AO board (with a wire). Then change the source for the AO Timing.vi to Devx/PFI0. If you want to do triggering, stick the DAQmx Trigger.vi between the Timing property node and the DAQmx Start.vi on the AI task. I have shown how to do this in the modified version below. Please take a look at it and let me know if you have any questions. If you still get an error please take a screenshot of it and post to the forum. Have a great day!
Sincerely,
Marni S.

Sending AT command from xbee pro to read the data from device

I am new to serial communications using Labview.
I am having trouble with starting up the project, where I have to design the software that involves XBee pro module.
I need to send the READ command to read the data from a device. Then the software should go to the AT command mode (we enter the AT command mode by entering +++)
Then I need to read the energy level of the device by entering the command: ATED. The software should continuously read the energy level every 30 seconds, which will be displayed on the front panel.
I am not sure where to start the software from. i.e. how to enter the Read command and then the AT command.
I am hoping someone can suggest how to start this.
Thanks in advance.

Hello Manny,
You could also review the discussion from the link below which may also guide you in a good direction with your project.

Can I use LabVIEW to load data directly into system memory? The serial card I'm using isn't supported by NI nor does VISA recognize it. I'm using a Win32 function to read the data from the card and now I want it to go directly to system memory.

Can I use LabVIEW to load data directly into system memory from a VI? The serial card I'm using isn't supported by NI nor does VISA recognize it. I'm using a Call Library function to read the data from the card and now I want it to go directly to system memory.
The data is being received at 1Mbps.
Thanks

Two questions:
One, if it's a serial card, then presumably it gives you more serial ports, like COM3, COM4, etc. If so, VISA would see the COM ports, and not the card directly. The drivers for the card should make it so that you see the extra serial ports from the OS. If you don't see the extra COM ports from VISA, then it sounds like the drivers for the card are not installed properly. Do the extra COM ports show up in Device Manager?
Two, you said that you're using a Call Library function to get the data and you want to put it into system memory. Errr.... you just read the data and you have it in memory by definition. Are you saying you need a way to parse the data so it shows up on a graph or something?

I have a VI and an attched .txt data file. Now I want to read the data from the .txt file and display it as an array in the front panel. But the result is not right. Any help?

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

How to read the data from an internal table,when column names are known

Hi All
I have a specific requirement. I got an internal table with many fields (let it be my_tab). Some of the fieldnames (column names in internal table my_tab) are stored in separate internal table(let it be my_fields).
I need to store/read data corresponding to the fields (whose name is stored in my_fields) from my_tab.
I am able to build dynamic table (referred by field-symbol) with respect to the given field names in my_fields.
But i am unable to read the data corresponding to the fieldnames from my_tab.
Please provide me some pointer in this regard.

How to read the data from a column that is in clob data type (but XMLdata)

Hi ,
I have a table XYZ which has a column RESPONSE_XML in clob datatype format.we can convert it to XMLTYPE(RESPONSE_XML) to read the data in XML format.
Now this is the DynamicXML schema file. Here I want to see all the COMMONNAME, ResourceDescribedby_VALUE into column_A, ResourceDescribedby_ResourceSpecCharacteristic_Name tags into column_B
How can I do that .. any suggestions please ..

you don't appear to have posted valid XML, so I can't reproduce using your example, but you will need to look at something like this:
select xtab.common_name
from your_table yt
      ,xmltable('/SearchResourceResponse'
          passing xmltype(yt.response_xml)
          columns
              common_name varchar2(20) path 'SearchResponseDetails/CommonName'
      ) xtab

Reading the data from one component view into another component view

Hi All,
I have requirement to read the data from one component into another component while creating the service order. Here are the details.
Main View for Service order: BT116H_SRVO in that we have two assignment blocks like Organizational data(BTORGSET) and amount allocation(BTAMNTALL).This two blocks are two different component which are associated with main component(BT116H_SRVO).
I need to read the sales org data from component/View(BTORGSET/Orgsetdata) into Component/View(BTAMNTALL(HdrBillPlanDet) method DO_VALIDATE_INPUT.
I searched in SDN but all the posts are related to the data exchange between two views in same component. But My scenario is different as explained above.
Refer the attachments for the component link..
Please let me know how we can achieve this one..
Thanks,
Sapsar.

Finally I was able to fix my code...My Mistakes were need to read the parent node above three levels and need to use the relation entity name while reading the data..
Below is the correction code

     lr_current ?= lr_iterator->get_by_index( iv_index ).
     lr_entity ?= lr_iterator->get_by_index( iv_index ).
   ELSE.
     lr_current = collection_wrapper->get_current( ).

         WHILE lr_entity->get_name( ) NE 'BTAdminH'.
           lr_entity = lr_entity->get_parent( ).
         ENDWHILE.
*Get the related entity
         IF lr_entity IS BOUND.
           lr_collection ?= lr_entity->get_related_entities( iv_relation_name = 'BTHeaderOrgmanSet' ) .
           IF lr_collection IS BOUND.
             lr_orgset_m = lr_collection->get_current( ).
