Data transfer fpga

Hello,
How can I transfer two values, one FxP and one timer value, from the fpga to the RT host simultaneously so I know which timer value corresponds to which FxP value on the RT host. With DMA FIFO it is not possible to select "custom control" as the data type.
Thanks in advance,
Dries

Hello Dries,
There are 2 interesting conversion function that can be used in LabVIEW and in LabVIEW FPGA.
These would simplify the code even further:

This should do the trick.

How To transfer Data From FPGA to Host?

Hi, I am using Crio 9025 Other Input card for my project.
I am acquiring current input using 9203, and incoder input using 9411 differencial DI module.
I am getting encoder pulse count perfectally in both the direction.
Now What i have to do is. i want to store current input at each encoder pulse.
for example
Pulse number AI1       Al2
     1                30.50    30.89
     2                26.78    26.98
till last pulse.
1024                35.89    31.45
Thats It. Test Over.
What is the best why to do this.

Hi Brijesh,
Kindly have a look at the NI example finder, I am sure you will find DMA or IRQ methods of data transfer.

MyRIO memory, data transfer and clock rate

Hi
I am trying to do some computations on a previously obtained file sampled at 100Msps using myRIO module. I have some doubts regarding the same. There are mainly two doubts, one regarding data transfer and other regarding clock rate.
1. Currently, I access my file (size 50 MB) from my development computer hard drive in FPGA through DMA FIFO, taking one block consisting of around 5500 points at a time. I have been running the VI in emulation mode for the time being. I was able to transfer through DMA from host, but it is very slow (i can see each point being transferred!!). The timer connected in while loop in FPGA says 2 ticks for each loop, but the data transfer is taking long. There could be two reasons for this, one being that the serial cable used is the problem, the DMA happens fast but the update as seen to the user is slower, the second being that the timer is not recording the time for data trasfer. Which one could be the reason?
If I put the file in the myRIO module, I will have to compile it each and every time, but does it behave the same way as I did before with dev PC(will the DMA transfer be faster)? And here too, do I need to put the file in the USB stick? My MAX says that there is 293 MB of primary disk free space in the module. I am not able to see this space at all. If I put my file in this memory, will the data transfer be faster? That is, can I use any static memory in the board (>50MB) to put my file? or can I use any data transfer method other than FIFO? This forum (http://forums.ni.com/t5/Academic-Hardware-Products-ELVIS/myRIO-Compile-Error/td-p/2709721/highlight/... discusses this issue, but I would like to know the speed of the transfer too.
2. The data in the file is sampled at 100Msps. The filter blocks inside FPGA ask to specify the FPGA clock rate and sampling rate, i created a 200MHz derived clock and mentioned the same, gave sampling rate as 100Msps, but the filter is giving zero results. Do these blocks work with derived clock rates? or is it the property of SCTL alone?
Thanks a lot

Hi Sam
Thanks for the quick reply. I will keep the terminology in mind. I am trying analyse the data file (each of the 5500 samples corresponds to a single frame of data) by doing some intensive signal processing algorithms on each frame, then average the results and disply it.
I tried putting the file on the RT target, both using a USB stick and using the RT target internal memory. I thought I will write back the delay time for each loop after the transfer has occured completely, to a text tile in the system. I ran the code my making an exe for both the USB stick and RT target internal memory methods; and compiling using the FPGA emulater in the dev PC VI. (A screenshot of the last method is attached, the same is used for both the other methods with minor modifications. )To my surprise, all three of them gave 13 ms as the delay. I certainly expect the transfer from RT internal memory faster than USB and the one from the dev PC to be the slowest. I will work more on the same and try to figure out why this is happening so.
When I transferred the data file (50MB) into the RT flash memory, the MAX shows 50MB decrease in the free physical memory but only 20MB decrease in the primary disk free space. Why is this so? Could you please tell me the differences between them? I did not get any useful online resources when I searched.
Meanwhile, the other doubt still persists, is it possible to run filter blocks with the derived clock rates? Can we specify clock rates like 200MHz and sampling rates like 100Msps in the filter configuration window? I tried, but obtained zero results.
Thanks and regards
Arya

RT - How can I make data transfer to host faster?

Hi
I have created a program that acquires data on FPGA then transfers them to RT so RT can send them up to the windows host once UI is connected.
The program is based on message type structure as in NI's examples.
However, I have one problem the data to windows host is not transferred fast enough.
Pic1 shows the offending bit of code and FPGA.png what's hiding in the subVi.
FPGA is meant to acquire to cycles of a sine wave. In this case it approximately 40 ms of data at 25us sampling rate (40kS/s 8 channels). Later the data is sent to the host. As you can see I have a dedicated stream for data only and a different one for message passing.
If I disable the code in the case structure this loop executes in 39-40 ms, however when I start sending the data to the host the rate drops to 57-60 ms per iteration and that sooner or later leads to buffer overflow.
I have experimented with passing the acquired data to a different loop using a queue but that wasn't faster. I have also tried pipelining but that did not speed it up either. Would you have any suggestions how I could improve my transfer rates?
Thank you.

Hi barteklul,
There are 2 main methods of achieving fast data transfer between RT and Host PC:
1. Using the "Shared Variables", they allow you to transfer data deterministically from
RT to Host PC, usually are used to monitor data.
Please have a look at this article:
http://zone.ni.com/reference/en-XX/help/370622J-01/lvrtconcepts/rt_projectvariable/
This is the example code:
https://decibel.ni.com/content/docs/DOC-15928
The only disadvantage of such method is that if for example RT gets data really fast
your Host PC can miss some samples.
2. In order to receive all data from RT
(guaranteed 100% data transfer without missing any samples) "Network Streams" should be used.
It is a little bit more complex to implement, but if you want to store data to the file "Network Streams"
are strongly suggested. In addition "Network Streams" are not deterministic.
For more details about network streams please read this article:
http://www.ni.com/white-paper/12267/en/
At the moment I see that you are using "Network Streams" to transfer data and also I can see that you have some timing on RT
which can slow down the data transfer rate. I suggest you to transfer data to Host PC as soon as it comes into the FIFO.
Also if you transfer data just to monitor it, I suggest you to try Shared Variables method.
I hope that you will this information useful!

I just checked my BIOS and my current setting is set at IDE although it also mentions that the default should be AHCI. Currently I have a dual boot of Windows 7 (need it for Tax software) and Arch
So I guess, when I get the new HDD, I will first set it to AHCI and then install the OSes on it. See if NCQ helps any, and if not I will turn it back and re-install (if I have to). I am planning to have Windows only in virtualbox in the new drive.
Anyhoo, while I was in the BIOS I found two things which I had questions about :
1) Under Onboard Devices --> Integrated NIC , my setting is currently set at "On w/PXE" and it says the default should be just "On". Would it be ok to change it back to On since its a single machine and its not booting an OS on any server. I just don't want to have to re-install anything now since I will be doing that in the new HDD.
2) How would I know whether my BIOS would support a 64 bit OS in Virtualbox? I checked some setting under Virtualization, but they weren't very clear.
I will edit this post and let you know exactly what settings were present under the Virtualization sub-section.

ISSUE:regarding production version tab of MRP4 of data transfer using BD10

Hi all,
This is regarding production version tab of MRP4 of data transfer using ALE idoc (BD10).
When i transfer the data using BD10 the production version is received at receiving end through segment
but not created in MRP4 view tab.An error is coming as-
"You wanted to maintain the master record of the material AB_06.04.09(2). However, it is already being processed by the user EBGABAP and is therefore locked."
I logged in as-EBGABAP
Please help me resolve the issue.

Bottleneck in Data Transfer

We run a small network in our office consisting mainly of Intel iMacs we purchased several months ago. The server computer is a brand new Intel Mac Pro server with 4 500 gig drives raided together, two 2.66GHz dual core intel processors, all the other bells and whistles we could think of, etc. We added in two fiber-optic switches: one in the server room, one in the office. The switches connect to each other and the server with fiber optic cables, but the iMacs connect with ethernet cables.
We had the iMacs for a while but we just recently got the new server and upgraded our old 100 base switches. Afterwards we wanted to test out the data transfer speeds, as we plan to back up to the server frequently. We were dismayed to find that transfer rates capped out at 60 MegaBytes/sec according to the Activity Monitor's Network Activity tab. In fact, it would range mostly from 40-45MB/sec. None of us here have much experience with networking, but that seemed a tad too slow. My basic math tells me that a byte is 8 bits, and from that a Gigabit network should transfer data at 120 MegaBytes/sec, which is three times the speeds we were actually seeing.
We sent data both to and from the server in order to test this. Thinking it was perhaps a problem with the ethernet itself, we grabbed an external FireWire hard drive and transferred data from one of the iMacs directly to it and noticed exactly the same transfer rates. We plugged two iMacs directly into each other and transferred at the same rate, ~45MB/sec.
Well this was highly frustrating. All Macs supposedly ship with Gigabit ethernet since, what, 2002? Earlier? Why are our speeds so slow? We thought the hard drives might be slow, so we got info on the drives and googled them for their tech specs. The iMacs' Western Digital drives are capable of much much faster speeds according to everything we've read.
We started reading anything we could online that addressed this issue. Some information read the problem might be that the optical DVD-R/CD-R drive was only capable of slower transfer speeds. Since the optical drive and the hard drive are on the same bus it would slow down the hard drive's maximum transfer rate, much like having a Gigabit hub with a 10 base computer plugged into it would slow the entire network down (which is of course why we use switches instead of hubs). Is there any truth to this? If this is, in fact, the case, can we bypass this bottleneck somehow? I'm not talking about opening the computer and manually disabling the optical drive, as that's a waste of a perfectly good DVD-R/CD-R drive.
Also, if this is true, why in blue blazes is Apple flaunting Gigabit ethernet if the computer can only take advantage of 1/3 the speeds Gigabit ethernet has to offer?! I'll happily provide any more information that's relevant to the problem at hand.
Thank you
Mac OS X (10.4.8)

Here's the specs for the default Hard Drive that Apple put in here:
http://www.westerndigital.com/en/products/Products.asp?DriveID=137
From that page
Buffer To Host (Serial ATA) 300 MB/s (Max)
Buffer To Disk 748 Mbits/s (Max)
I have no idea what signaling overhead for my data transfer protocol means.
The ethernet cords are no longer than 20 feet, are all Cat5E, and are well shielded. There is little to no ElectroMagnetic interference in any area they run. The longest cable is the Fiber Optic one, which runs about... oh... 40 yards? These were all installed by professionals.
I feel it's important to stress the fact that we tested an isolated direct computer to computer transfer with a single 6 foot Cat5E Ethernet cable and still experienced the same speeds that we experienced over the network. We tested multiple computers, multiple cables, multiple files.

Issues with data transfer / connectivity

Hi,
I bought a Curve 8320 last week and activated BIS. The issue that I am facing is:
- Mails do not get delivered and connectivity to the internet is lost even though the data signal (EDGE) is available. I can see an upload arrow flashing on the right top corner
- What I have noticed is that the connectivity gets resumed when I do any of the following:
a. Switch on WiFi (immediately the data connection starts receiving and sending messages and internet connectivity is resumed). Even after switching off the WiFi, it works fine
b. Switch off the device and restart
Can someone help me? Please let me know if you need any more details.
Thanks

You can try using FExplorer and using it to delete the file C:\system\shareddata\101ff93b.ini from the phone. It should reset the Data Transfer app.
FExplorer you can find here:

Init w/o data transfer shows Added/Transfrd - 1/1

Hi ,
Init w/o data transfer load was successful after having applied Note 689964 - ODS object: Switching from a full to delta upload !
I have two weird ( nt sure ) issues below :
Issue 1
On Manage screen I see Added - 1 & Transferred - 1, however I dont see this record in the DSO ( Display data ).
Why is that so ?

Issue 2
All seems green excepting when I go check the Details Tab - I see some reds
DataStore Activation (Change Log) : Errors occurred
No data targets selected for update. Action terminated.
InfoPackage ZPAK_*** could not be started by Bapi_ipak_start
Errors in InfoPackage check for DataStore 0CCA_O09 ; no update possible
Please comment SDNer's

Dear Jr.Roberto,
Issue 1
On Manage screen I see Added - 1 & Transferred - 1, however I dont see this record in the DSO ( Display data ).
Why is that so ?

--> When you do a init with out data transfer, system transfers one record that is not corresponding to the data, but is a control record corresponding to the init selections.
Issue 2
All seems green excepting when I go check the Details Tab - I see some reds
DataStore Activation (Change Log) : Errors occurred
No data targets selected for update. Action terminated.
InfoPackage ZPAK_*** could not be started by Bapi_ipak_start
Errors in InfoPackage check for DataStore 0CCA_O09 ; no update possible
---> It is because you dont have a active update rules maintained for the infosource to the data target, or you have not selected any data target in the infopackage , it can also be the case that the infopackage which generates a program to start the load is having some errors, if possbile create another infopackage and start the load with active Update rules to data target.
Cheers!!!!

Time Capsule only runs with 1,1Mbit up/down during data transfer, internet speed is ok, TC is used to extend an existing network

Hello Everyone,
I have a new 2TB Time Capsule running with a MacBook Air. I want to use the TC to access data (Aperture library, iTunes library, other Files) and to backup my MacBook Air via Time Machine. I set it up, integrated the TC in my Network (FritzBox) by choosing "extend existing network" and it works. BUT only with 1.1Mbit/second while writing or reading Data to/from it. Internet speed is very good, like it was before. While the 1.1Mbit/second seem to be ok with Aperture and iTunes (streaming music and movies) it is still painfully slow and I'm not realy happy with that
I've read that:
The 1.1Mbit problem is pretty common when Time Capsule is integrated and used to extend a network (bridge modus), it also looses all ethernet connectivity then (that woul explain why connecting it by ethernet didn't help during initial setup and data transfer)
Is there a solution besides ditching the Fritzbox and using the TC to build the network? Because basicly I still need the Fritzbox for its DECT features.
Thank you for any help in advance and have a nice day,
Olli

You have double hop wireless with this setup..
You should bridge the TC.. that is router bridge not wireless bridge, and plug the TC into the Frizyboy by ethernet.
Then you can setup the TC wireless to reinforce the fritzy..
Same wireless name as SSID.
Same security settings... really should be WPA2 AES or in TC personal.
Same password..
Just different wireless channel.
Then you can use 5ghz on the TC if you are up close and personal.

Data transfer b/w SAP to Java using IDOC and Interface SAP Jco

Dear Experts,
The challenging requirement we are having is, we need to create the interface for data transfer between SAP system and the Java system. The data will be transferred from SAP to java and similarly once some processing done in Java again the details needs to be transferred from Java to SAP.
For this data transferred we are planning to use IDOC process and for interface "SAP Java connector (Version 3.0.5)" we are planning to use. As per our understanding, from Java side one program needs to be written to connect with SAP as "Registered program". This registered program will appear in SAP GATEWAY automatically and using tRFC, TCP/IP connection both SAP and Java system will be connected.
In this case we are having some doubts.
1. The data from SAP is going to be transfered from one Custom transaction (Z tcode). Once "Outbound IDOC" will get triggered and will carry the details. Now the doubt is, whether the data / details will get transfered to JAVA system automatically or we need to perform any other steps from SAP ABAP coding...(like converting in to flat file, XML file and etc) ??
2. We are planning to install "SAP Jco" in Java server. Is this correct...??
3. Other than SAP Jco any other softwares needs to be installed or not..??
4. Since we are going to trigger the "outbound IDOC" from custom transaction, we are planning to develope one program in SE37. Other than this any other program we need to develop or not..??
5. Any sample Java program for the SAP Jco version 3.0.5 to create the "Registered program" with SAP..? (e.g. SAP Listener program).?
If anybody has detailed steps or explanation please share it with us.
Thanks in advance
Warm Regards,
VEL

Hi All,
For the above mentioned issue, we implemented JCo software in JAVA system and created the JAVA program including SAP logon credential details like Client, User name, password and Language details.
When this JAVA program was compiled successfully then, that non SAP system will appear in SAP gateway Tcode.
Once non SAP system started appearing in SAP gateway that means, both SAP & Non SAP are connected automatically.

Velmurugan P

Need to build communication redundancy using serial RS-232 for Data Transfer b/w Host and RT irrespective of TCP/IP Data Transfer

Hi - I would like to build the logic in which it should accomodate the communication redundancy using serial RS-232 for Data Transfer b/w Host and RT irrespective of TCP/IP Data Transfer.
I want to do data transfer b/w host and RT through RS232 VISA portal whenever TCP/IP ethernet cable has been unplugged from the controller continuosly , it should keep on checking for TCP/IP link re-establishing also , when ever the tcp/ip link established again that time the communication should be using in that link only. This is accomplished by deploying the RT vi as execuatbale file. I made some logic regards to the above said logic , bur it was not working as much I expected.
I request you to go through the attached two VI's and let me know , what I did wrong in that,
Please do the needful.

Problems with Photoshop performance and data transfer speed on iMac

Two months ago, I started noticing slow performances using Photoshop (above all using clone stamp tool) on my 27" iMac (late 2012). I did the AHT and I found that 8GB of 32GB RAM were broken.
I removed them but the problem didn't disappered, I also noticed that data transfer speed (both copy and paste from/to internal HD and from CF card/external HD) was really slow.
I tried many solutions suggested by Apple support, none of them worked out. At the end, I tried uninstalling and re-installing Photoshop: no more problems!!!
10 days ago, I received a new 8GB RAM module and so I installed it back... suddenly, the problem came back, I tried re-installing again Photoshop but the problem, this time, still persist!
Does anyone had the same experience? All other CC programs work well (LR, AE, Premiere...)

yes, it does!
what seems to be very strange to me is how data trasnfer speed could be affected!
(just to say, I've already tried reset of SMC and PRAM, I've tried with different accounts and I've also re-installed the OS, next step would be formatting the disk and installing the OS from zero)

What is the difference between copy requirement and data transfer routines

Hi Experts,
I am writing a copy control routine for maintainence quote
from sales quote.Where do i have to write it in VOFM?
Is it in copying requirements or data transfer.
Actually according to the business all the line items from the sales quote are copied
into the maintainence quote and additional line items are added into maintainence quote
and the line items copied from the source document are linked to the two newly added
line items.
Please advise.
And is it possible to add the 2 new line items to the new document into VBAP at the runtime?
Regards,
Chitrasen

First of all you have to have a link between the sales documents. You can check it in Tcode: VTAA. if not, talk to your functional people. Try to make this equal to quote to order but instead make it quote to quote.
You need to put break point in copy requirement as well as in data transfers and check for your requirement.
Well, the code you want to put in will be the requirement
I am not sure if you can add 2 line items runtime into quote. this has to go through different checks and i dont think it is possible.
Good luck
