Error reading more than 200 samples

I get an error trying to read more than 200 samples using the DAQ Assist express VI in case 2 of the attached VI,
The error reads:
DAQmx Read (Analog 1D Wfm NChan NSamp).vi:1<append>
Property: RelativeTo
Corresponding Value: Current Read Position
Property: Offset
Corresponding Value: 
Task Name: _unnamedTask<4>
Kinda new so not really sure were to start.
Thanks for the help.

Ok, there is some math here. You are sampling at 20Hz. 200 Samples at 20Hz gives us 10 seconds. If you go to the Advanced Timing tab of the DAQ Assistant, you will see a timeout setting. It is currently 10 seconds. So if you try to sample more than 200 samples (10 seconds worth), you will timeout. If you want 400 samples, you need the timeout to be at least 20 seconds or sample faster.

How do I do to read more than 200 emails of Microsoft Exchange Server ?

Dear All,
I need to read lots exchange emails more than 200 in iPhone.
Could tell me how I can do?
Best Regards.
Pike.Chiang

If there are more than 200 messages in a mailbox, there is or should be a load more messages selection available at the bottom of the mailbox to load more messages that are available on the server.

I am running a strain gage test and can't get more than 1000 samples

A formor employee left a strain gage VI that I am attempting to reuse but no matter what I do I can,t get more than 1000 samples before needing to restart the loop. In the task timing (of NI-DAQmx) I have set the acquisition mode to N Samples and the clock settings to read 65000 samples at 25 Hz. There is a DAQmx timing(sample clock) VI that resets to finite samples and 1000 per channel when I close it but I have reset it to 65500 continious samples and left it open to no avail. There is a rate input to this sample clock on the front window that I have tried setting to several different rates to no avail. The Vi will run about 15 seconds, collect 1000 samples and then ask to verify the file location to save the data to. Upon verifying the file location the VI will run another 15 sec. loop before stopping for verification again.
If the loop is stopped rather thanhaving the file verified an error is listed:
Error-200278 occurred at DAQmx Read (Analog 1d WFm NChan NSamp).vi:1
The given possible reason given is: attempted to read a sample beyond the final sample acquired.
When I stop attempting to run the VI the block diagram opens with a dark block around file creation block. I need this VI to run for 10 min. collecting samples at about 25/sec. Can someone help me figure out what I am doing wrong?
I have made screen shots of the VI and the error code to assist finding the incorrect programing.
Thank you for your help.

strain test error.doc ‏493 KB

Thank you,
I was just thinking about being able to increse the size of the doc. for better visability. I have tried working with the rate input for the DaQmx for the sample clock and it does change the frequency of sampling, but I still get just the 1000 samples. I have included Jpegs this time. I have tried to exppand the two DAQ assistants that arn't expanded but am unable to, I also am unable to find a "propertys" command to open them up and see what exactly they do. The nested while loop for output also seems strange to me. Maybe I would be better to attempt a new program but being new to the language I thought using an existing program might be best.

SP01: More than 200 downloads of SP01 - great! Please give feedback here:

Hello,
2005A SP01 PL02 has been downloaded by more than 200 different SAP Business One partners. That's great and proves the high demand for allowing early hands-on across the partner community!
However, feedback is rare. Usually this means that no major issues occured and that the information given (e.g. in the documentation of DB and UI changes + potential compatibility issues) is OK as well.
That would be great!
Could you confirm - or reject that interpretation?
Thanks in advance,
Frank

I have been studying SBO 2005 A SP1 for a while. I have come to terms with the License Server issue.
However, I now have a new problem.
All the add-ons (for different databases) cannot start anymore.
When I tried Outlook Integration, I will a series of error messages, including
1. Resource error (no title)
2. Initialization failed (no title)
I am given a choice to
a. Restart Add-on
b. Log off the company
c. Continue without the Add-on
I chose the last option and I get a dialog box that says
BO_Outlook.exe - Application Error (Title)
The instruction at "0x016cf850" referenced memory at "0x02de2f48". The memory could not be "read".
Click on OK to terminate the program.
When I tried XL Reporter, the error messages are slightly diferent.
1. Unable to connect to DI. Resource Error (title = XL Reporter)
I was given the System Message with the 3 options. I chose 3. No further messages.
Any advice? These add-on modules were working fine.

Way to acquire more than one sample at a time into Labview from cFP?

In reading data from my cFP into Labview I see that I can use the FP Read.vi but it only grabs one sample per call (loop iteration). In other devices, I could just use the AI Acquire Waveform.vi to grab multiple samples per call. Can I use this for cFP? Is there another way to grab more than one sample per call from my cFP? I'm just running it from a host computer, not using RT.
My specific problem is that I have two things I want to do with the same signal, one slow (PID control loop) and one fast (data logging). If I put the FP Read.vi in the same loop as the PID control, I can only get one sample in the time it takes the PID loop to run which is too slow. I'm trying to think of ways around this problem.
Thanks,
Hosehead

Hello Hosehead,
With FieldPoint there is no way to acquire more than one same at a time like
you can with NI-DAQ. With the FieldPoint read and write VIs
you can only read or write a single point at a time.
Please see the Sampling
Speed of FieldPoint Modules document for more information on cFP
acquisition rates. This document explains how channels are updated, how
often the data is updated, and what happens if you miss samples. Please
note that you will be able to acquire more samples if you are running your
application on the RT controller and not on your host computer.
If this does not answer your question, can you please post more data about the rate
you want your PID loop and your data logging loop to run at.

CONVERT_OTFSPOOLJOB_2_PDF is not working with more than 200 pages

HI all,
i am trying to print out Inspection Results (OTFs generated by QGA3 Transaction) via the CONVERT_OTFSPOOLJOB_2_PDF funtion module.
But if the Inspection Results have more than 200 pages the FM only creates a PDF without content.
The PDF is there but it has 0 bytes.
This is how i fill the FM:
CALL FUNCTION 'CONVERT_OTFSPOOLJOB_2_PDF'
 EXPORTING
 src_spoolid = i_spool
 no_dialog = 'X'
 IMPORTING
 pdf_bytecount = wl_numbytes
 pdf_spoolid = wl_pdfspoolid
 btc_jobname = wl_jobname
 btc_jobcount = wl_jobcount
 TABLES
 pdf = tl_pdf
 EXCEPTIONS
 err_no_otf_spooljob = 1
 err_no_spooljob = 2
 err_no_permission = 3
 err_conv_not_possible = 4
 err_bad_dstdevice = 5

 err_spoolerror = 7
 err_temseerror = 8
 err_btcjob_open_failed = 9
 err_btcjob_submit_failed = 10
 err_btcjob_close_failed = 11.
Does anyone have an idea ?
Thanks and Regards
Volker

That's because the function reverts to background processing when the page size is over 99 pages (see the code). I posted how to handle this a while back but basically you can either use RSPO_RETURN_SPOOLJOB directly or you can continue to use your current function but you have to poll for the completion of the job (BP_JOB_STATUS_GET) and then get the resulting spool in RAW format with RSPO_RETURN_SPOOLJOB then convert it:
FIELD-SYMBOLS: <fs_line> TYPE x.
DATA: gv_pdf TYPE xstring.
CALL FUNCTION 'RSPO_RETURN_SPOOLJOB'
EXPORTING
 rqident = p_spono
 desired_type = 'RAW'
TABLES
 buffer = gt_buffer
EXCEPTIONS
 no_such_job = 1
 job_contains_no_data = 2
 selection_empty = 3
 no_permission = 4
 can_not_access = 5
 read_error = 6
 type_no_match = 7
 OTHERS = 8.
LOOP AT gt_buffer INTO gs_buffer.
ASSIGN gs_buffer TO <fs_line> CASTING TYPE x.
CONCATENATE gv_pdf <fs_line> INTO gv_pdf IN BYTE MODE.
ENDLOOP.

Case structure with more than 200 cases, slower lab view app

Problem Description :
i am currently making a vi which compose of a simple case structures, a case structure with more than 200 cases, what i noticed is that the more i added cases the slower the labview reacts, it takes time for me to route wire on each of the cases.
i dont know if there are any setting in the labview environment that i can increase the buffer size? i dont know... but its getting slow (only on the
vi with more cases in a case structure)
mytestautomation.com
...unleashed the power, explore and share ideas on power supply testing
nissanskyline.org
...your alternative nissan skyline information site

Can you clarify what you mean by "slow". Does it run more slowly or does it feel sluggish during editing?
Could you attach the actual VI?
Overall, I agree with the notion of local variable overuse. For example, you read the same local variable twice in the same case. Is there a need for this? Is there a chance that it varies between the two reads? Typically, you would place the terminal in front of the case structure and wire to all the locations where you need the value. This ensures that the data is consistent. Still, this should not cause any slowdown problem.
(On a sidenote, the code in the upper left corner is inefficient. You convert the same data to lower case with each iteration, so you might want to place this before the loop and do it only once (well, if you are lucky, LabVIEW will fold the operation, but still....). Also your "index array" operation can be replaced by autoidenxing of the 2D array on the outer loop boundary.)
LabVIEW Champion . Do more with less code and in less time .

Help! We have a form with more than 200 entries and when I looked at it yesterday it had one! When you download the form to excel they all show up. However, when I added another record today it disappeared. Can you tell me what's happening? I've been using adobe forms for 2 years with mass response feedback and have never had this problem.

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

Can more than 200 recent messages be pushed through?

Can more than 200 recent messages be pushed through?

I think the 200 'limit' is just what will be fetched initially - if you have more than 200 then if you scroll down to the bottom of them there should be a 'load more messages' option.

More than 200 users per org unit

Hi Experts,
We are implementing SRM 5.0 and replicating org structure from HR systems. We have some org units which have more than 200 users. Please advise if there is any issue with it.
Regards,
Kamal

Hi,
The 200 limit is for users generated through trasnc USERS_GEN.
If an organizational structure with a large number of dependent nodes is displayed in the overview area, access to the transaction can take a very long time.
Please refer to the following SAP OSS Notes ->
Note 503915 - PPOMA_BBP: performance improvement overview area
Note 389869 - Organizational unit with many employees
Note 405806 - Transaction PPOMA_BBP for new material group attributes

Query results more than 200 rows.

Hi all:
I have a problem with a query that results more than 200 rows.
Only show in a table 201 rows and warning about this message: "Query has exceeded 200 rows. Potentially more rows exist, please restrict your query."
Is possible that the query show all results ???
thanks!

Its still a warning. You can continue with work but definitely you can increase the value through the profile value. Anything within 500 wouldn't cause much performance issue.

Is there any way to have more than 200 messages in your inbox?

My iPhone 3gs only allows 200 messages in my inbox per email account. On the contrary, my girlfriends blackberry will hold 1500+ emails.
Does anyone know how to change the settings to allow more messages to be kept in the inbox or if the new iPhone 4 will allow more messages to be kept in the inbox?
Thanks for the help!

What you see in regards to the Show Recent Messages settings is the only thing available.
If a mailbox has more than 200 messages and you want to view more than the 200 most recent messages in the mailbox, there is a load more messages selection at the bottom of the mailbox or below the 200th most recent message.
Don't know if iOS4 will have different options available for the show most recent messages setting for a mailbox. iOS4 for existing 3G and 3GS iPhone will be released on 6/21. iPhone 4 will have iOS4 pre-installed.

Can someone confirm that "Sent" and "Trash" can hold more than 200 email?

Can some confirm that Mail on iPad/iPhone
can hold more than 200 email in the "Sent" and "Trash" folders, and that
setting "Show 200 Most Recent Msgs" affects only the size of "Inbox" ?
Thanks in advance.

Check the bit rate for your songs. If 200 songs use up 7GB, they must be in a large bit rate format.
In iTunes, highlight a song and click on File/Get Info/Summary and check the Kind, Size and Bit Rate. Apple's figures for the number of songs on an iPod is based on a four minute song at 128Kbps.
I have a song in three different formats in my iTunes Library. Notice the difference is Size for the different formats. The song is 3 minutes 55 seconds long.
Kind is AAC audio file. Size is 7.5MB. Bit Rate is 256Kbps
Kind is Apple Losslesss audio file. Size is 20.8MB. Bit Rate is 738Kbps.
Kind is AAC audio file. Size is 3.8MB. Bit Rate is 128Kbps
Notice the enormous difference. I believe the iTunes Store now sells MP3s in 256KBps format, wheras they used to be in 128Kbps MP3 format. For a given Bit Rate, the MP3 format is about the same size as Apple's AAC format.
So you will need to check several songs, because there will be a variety, I'm sure.

Is there any issues if we planning to have more than 200 concurrent users

Is there any issues if we planning to have more than 200 concurrent users in BPS ?
Thanks,

Depends a great deal on what type of users they are. Simply running reports? Should be manageable. All performing complex modelling - more of a problem.
And of course it depends a large deal on your supporting infrastructure as well! How many interactive processes can your server handle?
But back to planning, if these are all planning users - not just reporters - perhaps the biggest issue will be planning level design such that so many users are not locking each other constantly.
Be aware that locks are defined by the package definition that a user executes a layout or function against, and locks stay in place until the users ends his/her planning session - which means exiting a planning FOLDER or correctly existing the web application.....
