Acquisition / VI

bonjour
Je travaille sur l'acquisition des signaux à travers le cRIO. J'ai réalisé un VI pour chaque signal et un VI principal dans le quel j'ai mis un bouton pour Chaque VI mon problème est que je veux que le Vi s'exécute méme s'il n'est pas ouvert , j'ai essayé avec ce programme mais le VI s'initialise a chaque fois que j l'apelle .
voila ce que j'ai essayé de faire mais ça ne marche pas

Bonjour,
Je pense que tu pourrais lancer dynamiquement ton sous vi, il pourra alors s executer en parallele je t'invite a regarder ce lien qui t explique :

FA Acquisition - 21151: error while posting asset document: '100000006'

Hi All,
When I was performing the FA Acquisition for a fixed asset code, the above error message prompt. I am using SAP B1 8.8 PL 15. Before this error appear, I was able to perform all other transactions like FA Acq, Credit Note, Retirement and depreciation run.
After this error prompt, subsequently FA acquisition and other FA transactions will have the similar error. Even though the subsequent FA acquisition involved FA code that was able to post acquisition before.
Realized that it seems that if 2 users are performing the FA Acquisition and happen to press on 'Add' button at the same time, this error will prompt. Then you can't proceed with any FA transactions later even though another user is log off. Anyone have idea on this error?
Regards,
MH

Hi Too Mui Hwee,
What we did is to put letters on the number so the series will continue example there is already 100333, 100334, 100335 since the error is encountered from 100333. We add 100333A, 100334A, 100335A.
Thanks

Fixed asset acquisition report by month?

Hi,
We're using the fixed asset acquisition report thru tcode 'S_ALR_87012050 '.
but there is only the report date input with the last day of the fiscal year concerned.
Is there any standard report to see acquisition amount with month-end or specific date?
Thanks for your help.

Chris,
I have just one more suggestion. Even though you have to use a yearend Report date for a closed prior-year, you could define a range in the Posting date selection criteria. In other words, if you would like to see the acquisitions for a given month or range of months in a closed prior-year, then give a 12/31/PY for the Report date and a specified date range in the Posting date selection criteria.
Hope this helps.
Thanks,
Chad

Is there anyone who have tried these things?

How do I use bidirectional buffered acquisition with handshaking on the 6533

I would like to use the 6533 board to generate digital patterns from a spreadsheet file (transfered to a buffer) with handshaking on ports A and B. At the same time, I need to acquire digital patterns on ports C and D, also with handshaking, and transfer it to a separate buffer. I already have the two tasks working separately. However, when I put them togheter in the same Labview program, the acquisition seems to work, but the pattern generation doesn't. I also get the "Error - 10409 occured at Digital Group Config", saying that the specified group is in use.
Is there something special we need to do to use the same board for two seperate handshaking tasks? I read somewh
ere that the 6533 can do two simultaneous handshaking tasks, but how?
Thank you for your help,
Benoit

In the DIO Config.vi you must explicitly set the 'Group' parameter for both processes (Input and output) to different values, otherwise the defaut 'group 0' will be found in use by the second DIO config executed.

How do I substract an image at the time t with an image at t-1 to detect move in a grab acquisition

After the VI acquire in a grab acquisition, how do I substract an image at the time t with an image at t-1 to detect the movement in the scene?

Hello,
One way of doing that is to do a ring acquisition with two buffers. At anytime one of your buffers will be the most current frame and the other will be one before the most current. Having both buffers available at anytime in your code you can call IMAQ Subtract.
Hope this helps!

i have problem while running the depreciation for asset sub sequent acquisition
my asst master is 4000
first acquisition on 01.04.2011 for rs 100000/-
we calculated depreciationwdv method for april month it's working fine
my client had done second acquisition for the same asset master on 01.07.2011 for rs 50000/-
while running depreciation for july month it's calculating dep for first acquisition as is same , the problem is for second acquisition also it;s is calculating dep from 01.04.2011
for this in period control method where we have to change the settings

Creating a PR for acquisition of an asset

Hi everyone,
This week some friend were talking about the process to buy an asset and we're a little bit concerned about the situation below.
A user created at IMA11 a request to buy some laptops and then he created an internal investment order related the IM request made before. So far everything is fine.
He called our asset sector and asked it to create an asset number related to the internal order that he has been created. With the asset number the user gone to the ME51N transaction to create the PR using the asset number provided by the asset sector.
At this time, for some reason, he didn't notice and instead of buy some notebooks he bought some chairs and the system didn't alert him telling that the asset number are for laptops not chairs.
Is this correct, or the system really doesn't provide that kind of information and an asset number created for some particular demand can be used to buy everything that the user wants?
Another thing, we've noticed that the asset number can be used for more than once, is this correct as well?
PS.: In our company IM management isn't turned on, I mean, Investment acquisitions doesn't check budget .
Thanks a lot for your answers.

Hi AP,
When the user is creating the request via IMA11, there is a tab called Variant.
In this tab, there is an option called Plan Values. In this option the user can assign that the request is related to a Material by inputing the material code. But, based on you've said before, I realized that there isn't any constraint between the material code choosen in IMA11 transaction and the material code choosen in ME51N.
Thanks.
Best Regards,
Rodrigo

Report for acquisition account and vendor account

hello
does anybody know whether it's possible to create a report for Financials to have a certain Acquisition account situation FOR A FIXED VENDOR?
i.e. the amount of acquisition for VENDOR X (I need in Balance Sheet for a group)
Thanks a lot in advance!!
Chiara

Hi
For the GL accounts where you need Vendor Number to be displayed,
Edit their master data field sort key to "012"
The you would get the vendor number in the "assignment" field.
(May not work for the existing invoices, but should work for new invoices)

Fixed Assets Report on Acquisitions & Disposals

Hi,
Dear Friends could you please advise as to how can we generate the Fixed Assets Report for acquisitions and disposals of assets? Also we need to generate a report on Fixed Assets giving the complete details on opening balance, depreciation, acquisitions, disposals and closing balances.
Your help would be much appreciated.
Thanks in advance.
Regards

Hi,
The following reports should meet your needs:
Asset History Sheet - Tcode AR02 - opening balance, depreciation, acquisitions, disposals and closing balances
Asset Acquisitions - Tcode AR05 - acquisitions
Asset Retirements - Tcode AR06 - disposals
Thanks,
Chad

Driver missing - PCIe Data Acquisition and Signal .....

Hello, i recently used Boot Camp to install Windows XP on my 2010 15" Macbook Pro.
All the drivers are working (so far) and i haven't encountered many problems.
However, there is one thing bugging me:
When i go into Device Manager in Windows, and look down the list of installed/uninstalled devices, there is a device called "PCIe Data Acquisition and Signal Processing Controller" which has no driver installed.
I'm PC savvy, but i have never seen this before. My guess is that one of the motherboard drivers is missing, and Boot Camp installer doesn't include that driver?
Has anyone seen/resolved this, and if so, how?
Thanks.
Kaj.

Okay, will do.
Thanks.
Also i wonder if you could help with another problem?

Data acquisition from SR 530 lockin

Hello,
I need to read the output of the sr530 vector lockin and store them in a file.
I was wondering if there is any driver which will let me read frequency, output amplitudes & relative phase between the input & output signal!
Any help will be much appreciated!
Thanks a lot,
Ashutosh.

Thanks a lot for the help Matt.
I can connect the device via GPIB. Let me tell you a bit more about the problem. As of now I was using a single channel lockin, EG & G 5209, to read the data(so I am kindda familiar wtih data acquisition... not much though). And the only thing I was reading was the output amplitude of the lockin.
Now I have to use the vector lockin, SR 530, and I will need to read both the output amplitudes, the phase & the frequency (all four of them)at the same time. And I am looking for a driver which can do this, i.e. which can read all four data simultaneously & store the result in a *.txt or *.dat file.
Do we have something like that?
Thanks,
Ashutosh.

Data acquisition in a state machine

I've recently learned how to implement state machines, but I have a question that I haven't been able to find an aswer to.
Question:
How do I record uninterupted data (presently i'm using the DAQ assistant to record a single channel at 10kS/s at 1kS intervals) without interfering with my state machine?
Background:
I have a time sensitive test setup (measuring pressure in a rocket chamber), and I'm using labview to both record a single pressure transducer as well as operate the valves (O2, N2, igniter, etc). I'm using a state machine Labview architecture (just learned how). Presently, the DAQ assistant sits in the "Idle" state, and timers (valves need to be turned on at specific times) and manual buttons control when the other states are activated. I have a 10ms timer controlling how often each state is run, and this is the root of my concern.
Main concerns:
I'm worried that:
1) I'm forced to change my data recording to 10ms intervals to match the 10ms timer, and
2) The 10ms timer will interrupt my data recording when it's in another state.
It's very important that the pressure data is recorded without interruption but that I have high time resolution in controlling my valves as well.
Thoughts:
1) Maybe I put the 10ms timer in the "Idle" state only, and this way the other states won't interrupt the data acqusition
2) Maybe there is a way to completely isolate the state machine for controlling the valves and the data acqusition. I'm not sure how to do this.
3) People on the forums have been talking about Queuing their data acqusition, but I'm not sure how this would benefit my situation.
Thanks to everyone for their feedback!

The data acquisition and state machine timer do not have to be equal, you should however have the same data write rate as you have data read rate, otherwise over the course of long running programs you can build up a large buffer of data to be written using a lot of memory, or lose data.
Your data acquisition should be continuous, the most common way of doing this is every time you receive data write it to a queue, then when you are in other states except your data write stage you simply build up data in the queue that is to be written when you enter the write state again.
Think of it as traffic reaching a set of lights:
The traffic represents the data acquisition, there is a constant flow of it always coming through, the state of your state machine is the lights, green is the data write state clearing the queue, red is when in any other state, letting the traffic build up behind the lights.
It is just important that the light is green long enough to let the traffic not build up too much, otherwise you have a jam.
EDIT: For the basics of how queues work, look at the Queue basics example from the example finder.
