No. of Channels in a PXI Embedded Controller

How many DMA channels are present in the NI PXI 8105 controller ? I have read that in NI PXI 7831 r, there are a total of 3 DMA channels, So if I am using 3 such cards I need to have 9 DMA channels in my controller for sending the data to these cards simultaneously.

I would rank your options this way (with #1 being the least demanding on your controller's memory):
1. FTP from the PC to the controller's hard drive, copy over the data, and then delete it. This way, the PC is doing all the work, and the controller is left to just gather data and do its own processing. The catch is that your network capabilities will determine how fast you can do this. Also, you'd have to make sure you aren't deleting data the controller hasn't processed yet.
2. Store the data in Shared Variables, so that both the controller and the PC can see and use the variables in real-time as they are updated. However, lots of shared variables = very messy code.
3. TCP/IP is your last option for transferring data. It will be the most demanding on the controller since it will need to open and close ports and handshake.
With all of these, you shouldn't lose any data if it's programmed properly.

ADLINK PXIe-3985 Controller - NI PXIe-1062Q Chassis Compatibility

Hello forum members!
we recently purchased a PXIe-3985 ADLINK PXIe Embedded controller to be installed in a NI PXIe-1062Q PXIe chassis. In our system is also present a NI PXIe-6672 Timing Module, installed in the chassis timing slot (4). Windows 7 installation, NI MAX toolsuite and NI PXIe-6672 Timing Module driver installation worked fine, but we discovered that the CPU is not able to recognize the TIMING SLOT. We cannot generate any PXI STAR signal with our NI PXIe-6672 Timing Module because it appears that the TIMING SLOT is recognized as normal peripheral slot. The PXI trigger lines and clocks are working well and usable, but not the PXI STAR signals.
I also tried to install the PXIe Chassis in the NIMAX toolsuite as explained in the PXIPLATFORM _50-17049-100_200.pdf document from ADLINK.
basically in the NIMAX device and interface tab I right click and try to add the pxie chassis.
First it is not understandable how can I find the bus identifier root of the chassis. There is a PXI bus tree, but no evidence of the PXI bus related to the chassis.
Furthermore even if I select one PXI bus, the NI PXIe-1062Q PXIe chassis is not listed and trying to load the corresponding .ini file from C://programs/nationl instruments/PXI/PXIe Chassis/ returns the error “Could not import Chassis information. Error Code 0xFFFB380E”
is the ini file working at all for my PXIe chassis? is there another procedure that I must follow to have my timing controller working or the chassis installed?
We definitely need this capability to test our equipment and I would like to know if there are known incompatibility issues between these three devices:
PXIe-3985 ADLINK PXIe Embedded controller
NI PXIe-1062Q PXIe chassis
NI PXIe-6672 Timing Module
And in case if there is an update or workaround which solves the issue.
The system has Win7 32bit installed.
Many thanks to every answering user

Hi emanuele83,
which version of PXI Platform Service do you use?
Can you please upgrade to a current version?
Here is a download link:

Problems directly connecting Windows 7 HP EliteBook to NI PXIe-8135 Embedded Controller

For some reason my computer cannot connect to the NI PXIe-8135 Embedded Controller in my PXIe-1082 chassis. My computer recognizes that there is something there, but it cannot communicate with it (no packets recieved back, but packets sent). I've already checked my firewall settings, network settings, and anything else I could think of that might be preventing me from connecting to it but I have not found a single thing that tells me why I cannot connect.
Any ideas on troubleshooting this problem, or if someone has run into the same problem please let me know - any help is greatly appreciated!
-flynneva

Hi flynneva,
Are you using an ethernet cable to connect to your PC? It sounds like you just want to add this chassis to your network just like any other computer (with the embedded controller is a computer). Here is a link to Microsoft's page on this type of connection in case you haven't tried these options:
http://support.microsoft.com/kb/305621
Also, is this embedded computer running Windows or is it a RT controller? What does your computer do to recognize the connection and what are you using to read the data? Can you ping the IP address of the controller and receive a response?
Thanks!

Video Output for PXI Embedded Real-Time Controller ?

I plan to purchase a PXI Embedded Real-Time Controller for security monitoring.
Is it possible to use the video output of a PXI Controller running RTOS to display messages from a LabVIEW RT application ? According to the documentation, it seems that the use of the video output is only possible for PXI Controllers running Windows XP.
Does it exist a specific application to do this with LabVIEW RT ?
Thanx.
H.L.
Solved!

Hi Yann,
The situation seems a bit confusing as in the link you've given above using the local monitor from a pxi labview rt system as the HMI without a pc attached, two messages (here and here) say that it is possible to display an image on the video output of a PXI RT controller using a function of the NI-IMAQ librarey (namely, the IMAQ RT Video Out VI) !
I have the NI-IMAQ library but no PXI controller to test if this solution should work or not
Does anyone have the answer ?
Thanx,

T43p Embedded Controller Upgrade

Dear All,
I upgraded the embedded Controller to 1.06 without pay more attention to BIOS version so the BIOS version was 1.22 and this is uncompatible version between 2 system software.
So now I have a big problem on running, sometimes the Laptop stop on the IBM Screen (Click Blue Button) and can't continue I foreced to turn it off manually then re-run it many times to let it run.
After that I upgraded the BIOS to 1.29 version but I am still getting this problem.
When I am working into Windows XP, 70% of the time the system doesn't work efficently and freeze a little bit but the big Problem when I am trying to run it I rerun it many times to work nice.
My question is; How to uninstall the BIOS and the Embedded Controller?
Regards and thanks

Hello,
The PXI controller can have one of two operating systems:
Windows OS
Real-Time OS (deterministic)
Ultimately, the architecture of your program will determine the deterministic rate.

Convert PXIe-8135 controller to dual-boot Windows 7 and LabVIEW RT

Hello. I have a PXIe-8135 controller that originally was just running Windows 7. We are trying to convert it to a dual boot system to also run LabView Real Time. (There is host computer that will run LabVIEW 2014 with the RT module, and the controller will become a target).
I have created a FAT32 partition on the hard drive of the controller. Now, I’m trying to install the real-time OS with a USB flash drive made using the MAX utility, but I cannot boot using the USB drive for some reason. I keep getting the message “waiting for USB device to initialize”.
In BIOS, legacy USB support is [ENABLED] and boot configuration is set to [Windows/other OS]. I’ve tried removing the drive, waiting, and reinserting. I’ve tried two different USB drives (both 8 GB, different brands).
I’m not sure what to do next. Apart from the USB boot issue, is converting the PXIe-8135 even possible? I read about SATA/PATA hard drive issues with older controllers, but I don't know about this one.
Thanks, in advance, for your help!

Per Siana's licensing comment, more information on purchasing a deployment license if you do not have one for this target can be found here.
The RT Utility USB key is used to set up non-NI hardware with LabVIEW Real-Time, but you should not need it in this situation to convert to dual-boot (*). Try this:
1. Since you already have a FAT32 partion created, go into BIOS setup and change to booting 'LabVIEW RT'.
2. The system will attempt to boot LabVIEW RT, see that the partition is empty, and switch over into LabVIEW RT Safe Mode. (this safemode is built into the firmware, which is why you don't really need the USB key).
3. The system should come up correctly and be detectable from MAX, and you can proceed with installing software.
4. To switch back to Windows, go back to BIOS setup and choose 'Windows/Other OS'
(*) One area where the USB key is helpful on a dual boot system is with formatting the disk. If you want to convert from FAT32 to Reliance on the partition designated for LabVIEW RT, the USB key lets you attempt to format a single parition and leave the rest of the disk untouched. If you format from MAX, the standard behavior is to format only one RT partition if found, but if not found, it will format the entire disk. Formatting from MAX on a dual boot system is consequently riskier and you could lose your Windows partition.

Memory upgrade on PXI-8105 and PXI-8106 controllers

Hi,
I've recently upgraded the memory of three PXIs; one with a PXI-8105 controller and two with PXI-8106 controllers. Both the 8105 and 8105 can take a maximum of 4GB (2x2GB) of DDR2-677 (PC2-5300) memory (see links below). However, on all three systems, both the BIOS and the O/S only see 3.3GB. Any idea why this might be the case?
I've tried flashing the BIOS (v1.4 on both PXIs), but with no success.
We're using COTS memory (i.e. not bought from NI) but I'd be hard pushed to believe that that is the cause of the problem.
Thanks.

Are these controllers running Windows? If so, this is normal expected behavior. I think it might have something to do with the fact that Windows reserves the rest of the memory for driver addressing (could be totally wrong there). The same thing happens on my Dell desktop PC with 4GB of memory in it.

How to use TRG pine in PXI-8176 controller

Dear All,
        I have Thermocouple data acquisition system. In which there are 2 chassis, (1) PXI 1002 with
PXI8176 controller with RT, PXI 6071E DAQ card (2) SCXI 1001 with SCXI 1125 card and SCXI1327 block.
PXI 6071E connected to SCXI 1125 with SH1006868 cable and adapter SCXI1349.
I am using Labview 8.6 , DAQmx9.0
I have develop program for continuous thermocouple acquisition. Now i want to make program on trigger based data acquisition. When trigger pulse comes system starts to acquire data ( and log in file) for userdefine time and stop acquisition. Again when trigger pulse comes   system again starts to acquire and stop at define time.
There is one TRG pin on PXI-8176 controller, Can i use that one and how i can use it? Or i have to use separate DIO line for trigger?
Can you guide me how i can develop such system.
Thank you.

Thanks Shreyas,
Once again you help me to solve my problem.
   As i have already mention you i have develop temperature measurement system with-out trigger. Here i am attaching my project. Now, how i can make it trigger based, means when trigger pulse comes acquisition start and target send data after some time for example 5minutes stop acquisition and restart acquisition again when next trigger pulse comes and so on.
Thanks

Problem with PXI-8145RT Controller.

Hi All,
I am preetam.
I am using PXI-8145RT controller in PXI-1011 Chassis.
My controller is having 64MB of Compact Flash and 128MB of SDRAM.
I configured the Chassis through host PC using MAX.
But if i restart the controller the configuration is going off and we have to reconfigure the controller again.
How can i store the configuration permenently?
thanks in advance and awaiting for ur reply
Preetam

line 16 on the Access List refers to allow ICMP Pakets on the whole network.
Line 16 does not cause the DHCP Problem. When we remove line 16 from the ACL the DHCP problem persists.
It doesen´t matter what changes we apply on the ACL. We have the DHCP Problem since from the start when we added the ACL.
When the ACL is removed, we don´t have any DHCP Problems.
Thank you

Correct procedure to update Embedded Controller Programme - T43

Dear Forum,
Could somebody please describe the best way to safely update 'Embedded Controller Programme' in a T43?
- The computer is a Thinkpad T43 1871 PM1 machine
- BIOS Version is 1.29
- Embedded Controller Version is 1.03
- Apparently this is the correct current Embedded Controller Version http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-59439
- Should I boot the machine into safe mode rather than regular startup?
- Should I deactivate my firewall (PCTools), my anti-virus (Avast) and Malwarebytes from running at startup before I shut my machine down?
- Are there any other specific programmes I need to shut down? (eg. IBM Access or any of the IBM updates?)
- Does the controller update require internet access? Or should I also disconnect the computer from the web?
Thank you!! :-)
Harryredknapp

Hi Harry,
There is no need to boot the machine in Safe Mode, and yes it would be good idea to deactivate your firewall and antivirus products for the time being while the controller program is being updated.
When I run BIOS update, I don't turn off any Thinkvantage tools so in my experience they don't interfere with the update process, and as far as I know the controller program doesn't require internet access (if you're doing manual update from the setup saved on your thinkpad).
Hope it helps.

ACPIEC Embedded Controller error in Event Viewer on XP Partition

So, when in my XP (SP2) partittion I recently started to get hangs when I try to put the system to stand by/hybernation at the blue "preparing to go into Stand by..." screen. It just sits there, locks up and I end up having to reboot. In the XP's Event Viewer I see this ACPIEC error and that seems to be related to the BIOS. But, as we know, I am on a Mac so there is no "BIOS".
It says "The embedded controller (EC) hardware didn't respond within the timeout period. This may indicate an error in the EC hardware or firmware, or possibly a poorly designed BIOS which accesses the EC in an unsafe manner. The EC driver will retry the failed transaction if possible."
So, that is the only error I consistently see in the Event Viewer so I assume it is related, but if I am on a Mac and have no "BIOS" or "EC" how can I source this issue out in XP given it is a partition on my Mac?

Motion control: PXI 7350 controller and UMI 7774 to interface with third-party driver UDK5114NW2

Dear community,
This is about Motion control in Labview: I try to control a step motor by using a PXI 7350 controller and UMI 7774 to interface with third-party driver UDK5114NW2. The problem is 5 Disable LEDS on UMI 7774 board always lit even when I check "enable" on "Motion I/O setting" in configuration of PXI 7350 motion controller. Furthermore, when I start to control step motor, it is not working and I found disable LED on UMI board still lit. I don't know how to solve this problem. Can someone help me to figure out? Thank you in advance!
Hau Nguyen.

Dear Community,
I said wrong, 4 disable LEDS on UMI 7774 Board instead of 5 as my previous post. Why nobody help me to solve this problem. I can not turn off disable LEDs on UMI 7774 Board so I can not start the strp motor. Please help me!

Pxi-8176 controller to read data from an instrument controlled by another controller

can i use pxi-8176 controller to read instrument data on the gpib bus from an instrument controlled by another pc gpib controller?

Thanks.
I understand what you're saying, but I'm also trying to understand why the following is not possible or is not more readily available:... Just as NI IO Trace (NI Spy) listens/eavesdrops to the GPIB real time, one would think that Labview would be able to do it also. One would think that just as NI IO Trace (NI Spy) publishes to a window/file/memory it shouldn't be impossible to publish to a string so that it can be processed real-time by some VI algorithm. If I think about NI IO Trace as a VI, I would think that it is already in a string format before it is published to the NI IO Trace window... why isn't that string available to Labview VIs block diagram?

How to configure Intel Pro/100 ethernet in PXI-8176 controller for RedHat Linux kickstart installation?

Not with Linux but...
I had trouble setting it up for RT.
There is an issue with the chipsets used and the firmware of the 8176 when sizing the bus.
There was a KB article.
