Displaying output data to a DAQ

Hi, I'm writing data (8 bits) to a DAQ, but at the moment it's in a unlikeable format. I need to write individual bits as in binary, but can only work out how to do this in decimal, e.g 127 instead of the preferred 0111111. I would also like to arrange this in a bank of 8 toggle switchs, where on represents a 1, and off a 0. Does any one have any ideas on how to accomplish this?
many thanks, tom

Your numeric display is just a matter of formatting. As long as the representation of the number is an integer, you just have to right click on it and select Format & Precision and change it to binary (or hex or octal). You can use Number to Boolean Array to convert the number to an array of toggel switches. This is on the Boolean palette. There is also the reverse function called Numeric Array to Number.

Is it possible to display a date as (DD-MON-YYYY) in excel output using excel template in xml publisher

Is it possible to display a date as (DD-MON-YYYY) in excel output using excel template in xml publisher where date should be displayed as date only not string.

I've tried to use hierarchy node variables, but it seems like you can't specify a attribute of the hierarchy such as level. So with the WBS hierarchy, if you create a hierarchy node variable, you specify the WBS value to select (If I understand this correctly). I wish I could instead specify "give me all the WBS nodes that happen to have the value of the level attribute greater or equal to 3. If I understand Juergens post, he is saying make security access so that only certain WBS levels can be returned in the query. I suppose we can try that, but that would then preclude getting the level 1 and 2 in the future if the authorization is global.

Applet Displaying Program Data(output)

Hi,
I have an Applet with a TextArea and a Button. Clicking on the Button starts a shell program. I want to
display the output of the shell program in the TextArea
as the shell program runs. How do I capture this data, or, how do I assign the output to the TextArea?
Any help will be greatly appreciated. Thank you.

Research Institute of America, Inc.

If you call the shellprogram per Runtime.getRuntime().exec()
you get a instance of class Process.
There is a method in the class Process to get the error- and the normal-output of the program.
Process p = Runtime.getRuntime().exec("myCommand");
InputStream input = p.getInputStream();
InputStream error = p.getErrorStream();
//Here should be the code for reading from one of the inputstreams
//and displaying the data in the textareaHope it helps,

Display output based on oldest date

I am developing picking list report. I have fetched the data into final internal table consisting of the fields material number, batchno, shelf life expr date, pick qty, actual qty and bin number based on some conditions from different tables. Now, my requirement is to display the data based on following condition
Using the Material Code, locate the Material master record on SAP. Determine if the material is stored by shelf life. If it is, find the batch with the oldest shelf life with available stock for the material and get the bin number in which it is stored. Write the bin number, shelf life, batch and quantity picked details to the record and write the record. If there is insufficient stock in the batch to satisfy the requirement in full, find the next batch with the next oldest shelf life and write those details to a second record and so on until the requirement is met in full.
Can anyone pls help me to write the logic ?

hi,
tell me first that japanese data is coming from table in japanese text ?
or u just needed to hardcode japanese text ?
if so u can write a format trigger .
Take taht particular column in a seperate frame and on that frame write a format trigger based on the user input for language selection.
try with this.
is it ok?r give me ur requirement clearly once.

Why replay history data from NI-DAQ buffer?

LabVIEW 8.6.1f1, NI-DAQ 8.8, Win Vista, two cDAQ chassis. (I can't move to LV09 or LV10 for this, not yet anyway).
I have a client with two cDAQ banks, each with 16 TC channels (on 4 modules) and 16 voltage channels (on 1 module), 64 channels all told.
The config operation is like this:
This is called twice, with TC CHANNELS and V CHANNELS describing the channel arrangement. Both channel descriptors are the same except for device number. The Sample rate works out to 1000 / 100 = 10 Hz. I am using CONTINUOUS SAMPLES, with no need for a buffer, but I understand that one is created anyway.
One loop of my main program is waiting on the READ function:
You can see the explanation of why the loops are there.
After reading the data (at 10 Hz), each frame is sent via UDP to somewhere, and every 5th frame is displayed, via another loop.
This program runs 24/7 on the same computer as another program.
All this works fine in normal circumstances.
However, occasionally, a weirdness creeps in:
In the mornings, after waking the screensaver (or the CPU itself, I'm not sure), we sometimes (not every time) get a very rapid display - the displays are changing much faster than the expected 2 Hz.
I've been wondering whether the data shown was historical, or simply faster updates of live data.
Today, it so happened that a blower was turned on just before waking the computer. The device takes 15 seconds to ramp from zero up to operating pressure normally, and then it stays there.
The readings on screen were frozen (unchanging). When the computer was awakened, what my client saw was the reading for the blower pressure ramp from zero to running pressure in 2-3 seconds, stay there for 2-3 seconds, drop quickly to zero for 4-5 seconds, and start the ramp again.
Over and over and over it replayed this data, way faster than 2 Hz. At least 40 times it replayed this same data, while the real pressure was just variations around the operating pressure. As time went on, instead of dropping to zero, it would drop to some point on the ramp up and repeat from there.
I don't know if it would eventually straighten itself out - the client gives up and restarts the program. All is well after that.
I've gone over my code several times, and I can't see a mechanism for me to store this data and re-play it.
Here's my best guess as to what's happening:
Since I am not explicitly setting the buffer size, it defaults to 1000 samples.
Since I'm running at 10 Hz, 1000 samples = 100 sec.
At some point, because of the screensaver, or because of CPU sleepage, or because of integer rollover, or because of zombie infiltration during the night, NI-DAQ has become confused.
When the mouse was wiggled, the gates were opened. After that, whenever I ask for a sample, it gives me one, without regard to read/write position. It continually gives me the next sample from the buffer and wraps around, again and again, and again, as fast as I can read / process / display.
It is also putting new data into the buffer, so that the historical data eventually gets wiped out.
That fits the facts:
  It shows only recent (last 100 sec) data, not ancient data, and not live data too fast, as I had considered.
  The data changes with time - oldest data gets wiped out.
  It plays the SAME data over and over and over.
But that means a bug in NI-DAQ, I think.
QUESTIONS:
Any flaws in my thinking?
Any previous sightings of this symptom?
Any ideas for workarounds?

The rapidly changing data, is that on the viewing machine or on a display on the device acquiring the data?
The "device acquiring the data" is a pair of cDAQ chassis. There is no display there. It's the LabVIEW program that is reading and displaying the data.
Does your computer go into any sort of power saving mode where the USB controllers are disabled during hibernation/standby?
on MY machine, I have tried this with CPU sleepage and such. Didn't know you could sleep the USB, but on MY machine, that's disabled.
But I haven't made it happen on MY machine.
My CLIENT's machine is actually running XP, and is set to turn off monitor NEVER, turn off hard disk NEVER, and system standby NEVER.
What version of DAQmx do you have installed?
On MY machine, it's 8.8 - I haven't found out from my client yet what his is, but it won't be far away from what came with LV 8.6.
Can you post your code?
Well, OK:
Here's two of the loops running (the third loop deals with TCP/UDP and is not relevant, I think).
The TCM DAQ manager 's READ function is pictured in the original post.
Here we wait on a sample, scale it (volts into EU), and feed it to the PROCESS TCM DATA vi (which does averaging).
Here's the NEW DATA function for PROCESS TCM DATA:
The ST (short-term) HISTORY is set up as an N channel by 5-sample array, and ST HISTORY SAMPLES is set to 5.
The DAQ loop, after processing this data, triggers a DISPLAY event, which triggers a DISPLAY action, which lands here:
The GET DISPLAY function retrieves the latest averages:
That data (64 channels worth) is split into two banks and displayed:
The display process simply distributes the array data into clusters (channels can be user-configured to be in various locations on the screen):
The UPDATE TIP action causes a TIP STRIP string to be updated:
The TIP STRIP shows the average and min and max values (which might be hidden from the display itself), based on which display cell the mouse is in.
A MOUSE ENTER event on any display cell sets the CLUSTER CONTAINING MOUSE variable to the CTL REF of the event, a MOUSE LEAVE event for the overall display bank (containing 32 cells) sets the CLUSTER CONTAINING MOUSE variable to Not-A-RefNum.
the DISPLAY looks like this (only a few cells shown). The display for this program occupies an entire 1680x1050 LCD display, another program runs on the main monitor.
As you can see, the only storage in this process is the AVERAGER, and that is limited to 5 samples (0.5 sec). It cannot store any more than that.
I've thought about the possibility of the mouse oscillating between two cells (as mice are sometimes known to do) when it is parked, and causing a flood of MOUSE ENTER events.
But 1) it happens more often than the odds would dictate (a random location is not likely to be on a cell border), and
2) When that cleared up, the queue would be processed, but it would display CURRENT data more rapidly than 2 Hz. NOT historical data.
Given that it seems to be about 100 sec of history (judging by my client's recap of what he saw, and how it operates), that points to the 1000-sample buffer within NI-DAQ. That's the only place that I see to store that data.
I'll admit that I'm not watching the ERROR output from the NIDAQ READ function. Perhaps I should.
The only scenario I can come up with is that NI-DAQ's READ pointer is confused.
When I ask for a sample it tells me that there is ONE and only ONE available. So I deal with it.
When I ask again, it tells me the same thing.
When I ask again, it tells me the same thing.
It goes round and round the READ buffer. At the same time, new data is coming in, replacing the oldest stuff.
But it (apparently) never gets back to the "normal" condition, where it WAITS on a sample at the RAD function.
Nobody has waited long enough to see if it would do that eventually, after a few minutes (50+ replays), they give up and restart.
Restarting the program resets the cDAQ drivers, among other things, so the problem goes away.
If there's another scenario to cause these symptoms, I'm all ears. But I cannot think of it.
If it was a USB SLEEP problem, I wouldn't think the data would replay from BEFORE the wake-up. But that's what happened.

Outputting data using an NI breakout box

For some reason in LabVIEW 7, when trying to setup a VI to output data through an analogue channel, the channel selection only lets me select input channels. Has anybody any idea why this is? Or more importantly how to get round this simple but annoying problem. (Note my VIs work in LabVIEW 6).

A common factor people miss when getting this type of error is in the properties of the Daq channel name control. If it lists only the inputs, right click on the control, and select I/O name filtering. From here you will see that the analog input channels are only being displayed. depending on the type you want, select the correct type from the drop down box. The reason for this, is because of the VI type you would connect this control to. if it were an analog input VI (aquire n samples) you dont want the end user being able to select output channels to it.

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 display the data of a structure in a report

i want to display the data of a structure resbd.
i know it does not have data.
but it contains data at runtime
plz help
thanx

Hi,
For displaying the data of a structure you can use the write statement.
WRITE : structurename - fieldname.
eg : write : resbd-rsnum.
Before that you need to declare the structure name inside the report.
Please refer the following code for your querry
REPORT ZSTRUCTDATA .
Table Declaration
tables : resbd.
Assigning Values to Structure Fields
resbd-rsnum = 1234.
resbd-rspos = 12.
Displaying Values
write : / resbd-rsnum.
write : / resbd-rspos.
This report will give the output like this.
0000001234

Go thru the guide for OOPs based ALV.
Use SET_TABLE_FOR_FIRST_DISPLAY to display the table:
CALL METHOD grid->set_table_for_first_display
EXPORTING
I_STRUCTURE_NAME = 'SFLIGHT' Structure data
CHANGING
IT_OUTTAB = gt_sflight. Output table
You can also implement
Full Screen ALV, its quite easy. Just pass the output table to FM REUSE_ALV_GRID_DISPLAY.
For controlling and implementing the FS-ALV we have to concentrate on few of the components as follows :
1. Selection of data.
2. Prepare Layout of display list.
3. Event handling.
4. Export all the prepared data to REUSE_ALV_GRID_DISPLAY.

How to Output data in vertically from a horizontal format.

Hello
I have some difficulties how to display my data in my output table. I am greatful for
every tips provided. The data in my it_tab is in a horizontal format but I want to
display this data vertically in my output_tab.
My it_tab looks like this:
table: it_tab
id   date   amnt
011 2007   1200
011 2008   1400
011 2009   6700

014 2007   1200
014 2008   ---
014 2009   9000
015 2007   2500
I would like my output_tab should look like this:
table: t_output
id name date amnt date1 amnt1 date2 amnt2 date3 amnt3
011 jx    2007 1200 2008   1400 2009   6700 2010   3500

015 hx    2007 2500
t_output already has some data init like id and name.
This is what I have done but I don't output all the data as I want.
clear w_output.
loop at t_output into w_output.
clear w_itab.
loop at it_tab into w_itab where id = w_output-id.
case sy-tabix.
WHEN '1'.
w_output-date = w_itab-date.
w_output-amnt = w_itab-amnt.
WHEN '2'.
w_output-date1 = w_itab-date.
w_output-amnt1 = w_itab-amnt.
WHEN '3'.
w_output-date2 = w_itab-date.
w_output-amnt2 = w_itab-amnt.
WHEN '4'.
w_output-date3 = w_itab-date.
w_output-amnt3 = w_itab-amnt.
endcase.
endloop.
modify t_output from w_output.
endloop.
Could some body please tell me how to do this? I think many people in here have come
across this type of problem before.
Thank you all for helping out.
Nadin

Hi, Nadin!
I suggest you to create a dynamic internal table with variable number of columns. You can do as follows:
1. Create basic fieldcatalog for ALV list (or object) output
CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
          EXPORTING i_structure_name       = 'ZYOUR_BASIC_STRUC'
          CHANGING ct_fieldcat = lt_fcat.
2. Determine max number of columns (that is, max number of dates for each ID)
SORT it_tab BY id.
LOOP AT it_tab INTO is_tab.
AT NEW id.
    ADD 1 TO l_count.
ENDAT.
AT END OF id.
    IF l_count > l_max_count.
      l_max_count = l_count.
    ENDIF.
    CLEAR l_count.
ENDAT.
ENDLOOP.
3. Add one entry to fieldcat for each column
DO l_max_count TIMES.
l_index_char = sy-index.
CONCATENATE 'DATE' l_index_char INTO ls_fcat-fieldname.
*... other fieldcat fields, like texts etc.
APPEND ls_fcat TO lt_fcat.
CONCATENATE 'AMNT' l_index_char INTO ls_fcat-fieldname.
*... other fieldcat fields, like texts etc.
APPEND ls_fcat TO lt_fcat.
ENDDO.
4. Create dynamic table from fieldcat using:
DATA: dt_outtab TYPE REF TO data. "IMPORTANT: make this declaration global, otherwise error
FIELD-SYMBOLS: <table> TYPE STANDARD TABLE.
CALL METHOD cl_alv_table_create=>create_dynamic_table
       EXPORTING it_fieldcatalog = lt_fcat
       IMPORTING ep_table        = dt_outtab.
ASSIGN dt_outtab->* TO <table>.
5. Fill this table. To do this you need special techniques since you have a generic table with no static structure. For example:
FIELD-SYMBOLS: <line> TYPE ANY,
               <field> TYPE ANY.
DATA: l_field_inex TYPE i.
LOOP AT it_tab INTO is_tab.
AT NEW id.
    APPEND INITIAL LINE TO <table>.
    READ TABLE <table> INDEX sy-tfill ASSIGNING <line>.
    l_field_index = 3. "you start from 3rd field - #1 is ID, #2 is NAME
ENDAT.
ASSIGN COMPONENT l_field_index OF STRUCUTRE <line> TO <field>.
<field> = is_tab-date.
ADD 1 TO l_field_index.
ASSIGN COMPONENT l_field_index OF STRUCUTRE <line> TO <field>.
<field> = is_tab-amnt.
ADD 1 TO l_field_index.
ENDLOOP.
6. Display your report in alv. You have valid fieldcat and output table which is created dynamically.
CALL METHOD o_alv->set_table_for_first_display
          CHANGING it_outtab       = <table>
                    it_fieldcatalog = lt_fcat.
If you don't use ALV object but rather ALV list, it's similar. Just use corresponding functions for ALV creation and list display.
Note that this is not a tested code. Just an idea to help you procede.
