• Problems to use two scb-68 has the NI PXI-6225

  Dear nor Forum,.

  I have a chassis NI SMU-1078, with embended OR PXIe8135 controller. One of the slot is busy with a PXI-6225. I for a long time successfully using 1 connection SCB-68 block a with the PXI-6225. Now, I need another channel to analog output on top of OD uses two that I am current. I plugged another SCB-68 connector Panel at the PXI6225, but I could not see analog outputs on this second bedroom. I could not see more channels to DAQmx AO create channel VI

  The PXI-6225 has only 2 analog outputs.  The second connector only has analog inputs.

  If you need more than output analog, you can take a look at the SMU-6738, which includes 32 analog outputs.

• I can't read thermocouples on the PXI-6225-series M 1 connector.

  I'm reading 30 measures by thermocouple in differential mode.  I use AI0 as the CCM.  Attached are the connections that I use.  Negative contributions all relate directly to the GND AI.

  I have no problem to read the thermocouples in slot 0 (AI1 by AI 7).  I have install Connector 1 direct feed by mode (switch 1 & 2 right and switch 3 upwards).  In MAX, I get a normal reading, but it does not vary by heating the thermocouple.  In my real program, it is as if there is nothing connected. Any ideas as to what I can hurt?

  Thank you

  Mark

  Mark,

  Thanks for posting. I think the question might be to see you about the how the SCB-68 must be configured in mode of direct crossing to be used with the connector 1 on the PXI-6225. When the switches on the block are defined for a direct crossing, the Council is not connected to the CJC. Do not have a connection to a CCM on this connector could cause this problem.

  A potential solution, you can try is to connect a temperature probe to AI16 and follow the steps in this KB, using that channel instead of the CJC channel. Let me know if it helps!

  Kind regards

• programming for PXI-6071e with SCXI1125

  Dear all,

  I connected the SCXI-1001 chassis with card Conditioning SCXI-1125 and SCXI-1327 block with PXI-6071E PXI-8176 with SH1006868 cable controller card. I chose the SCB-100 for PXI-6071 accessories, as there is no option to select SH1006868. I connected the Thermocouple on the SCXI-1327 block terminals.

  I am new to LabView, can someone guide me how to program. If anyone have example program, it will be useful to start learning

  Thanking you

  Concerning

  -Vishnu

  I don't think that you can select your accessory cables. Only the blocks for DAQ cards will be available on your list. Instead of the SCB-100, you can select the terminal box 1327? For starters, labview has a number of application examples. Go to the Help menu and select 'Search examples' then search for thermocouple. There should be examples on how to acquire tension of a thermocouple, graphic of your data readings, etc..

• Generation of signals (c) FIFO PXI-6225

  Hello.

  My user requests an upgrade a system existing.

  I'm an analog input I need to convert to a digital waveform. As the analog input varies, I need to be able to vary the frequency of the digital wave to match. Just recently, I discovered that I should probably use a line in Port 0 on my PXI-6225. I tried using digital model Generator.VI and writes the result to a Write.VI DAQmx. I wish that some checks before I'll and rewire my material that I'm on the right track.

  Thanx.

  Hi Bill,

  So it seems that you need to output a pulse train that changes frequency proportional to the voltage of your analog input (or proportional to an input of pulse train).  If this is the case then the best way to do it is actually NOT with correlated digital i/o but rather with one edge counters.  He would use the PFI lines rather than port 0.

  I would like to start by this example that shows how to change the frequency of an output of TTL meter on the fly:

  Output frequency of meter to change on the fly

  You can read your task of entry in the same line as the generation (or you can try instead an architecture of producer/consumer ).  I hope this helps, let me know if you have any questions!

  Best regards

• Many DAQ cards synchronize hardware for PXI

  I recently went through the process of getting several PCI DAQ cards in a computer and synchronize them together using a RTSI cable.  I just bought two similar cards in PXI.  I had to add a RTSI cable DAQmx devices manually in the measurement and automation software, and connect the cable with the PCI cards.  I want to just make sure that I don't have to do the same with the PXI cards because there is no necessary RTSI cable for PXI.

  Thanks for any help,

  Mike

  The PXI chassis has backplane triggering and clock lines so that you don't need the RTSI cable.

• Example rule for WebMonitor on Foglight 5

  Hello dear members,

  I'm looking for an example rule for WebMonitor agent.

  Kind regards

  David

  Could you not make a copy of the default rule and then select only the DEADLY condition and set the behavior through the tab behavior, such as the alarm goes off only if three consecutive samples fail?  Looks like that fits your use case.

• Remote access for PXI with DAQmx

  I have a PXI chassis with a real-time embedded (PXI-8186) controller and some modules DAQ (PXI-6259) x 2. I've been programming this via LabWindows with a kind of client-server of RT - UI thing by using network variables and others. For some applications, it would be enough and more convenient to be able to interact with the PXI hardware directly from a connected PC network DAQ.

  The controller running a VISA server, it seems that I could connect to a remote machine with a kind of viOpen ("visa://pxi.somewhere.com//PXI0::15:INSTR"); ") and then contact a particular data acquisition card. But I can't find any information on the programming of the 6259 in any way other than DAQmx or similar.

  First question then: is the interface PXI - 6259 VISA described anywhere?

  More practical would be to continue to use DAQmx, through something like DAQmxCreateDOChan (taskHandle,"pxi.somewhere.com//Dev1/port0/line0:4",...)

  I found references to what we call 'Remote access appliance', for example:

  http://digital.NI.com/public.nsf/allkb/5CC9792C6CD4A34C862565BC0072D5DF

  that seems to put in place something equivalent, but I don't find it to watch it in MAX:

  Start-> all programs-> National Instruments-> NI - DAQ-> the remote device access server

  and I've seen suggestions that maybe it isn't that for traditional DAQ or only pre 7.0, or in any other way was no longer applicable.

  Second question: "Remote device access" are always and how to I install/activate it on my PXI controller?

  Someone at - it clues as to the foregoing, or any other way to get the same kind of features?

  Thank you

  Hello Mike,.

  Remote device access was a feature in NOR-DAQ traditional long just now.  This feature was not worn on OR-DAQmx because the framework it was built on does not really correspond with the need of modern times for network security.

  Unfortunately, there is no functionality you describe by saying to DAQmx.  Currently, this type of control is limited to deploying applications to the target of RT.  While the VISA is used for some parts of the DAQmx interaction, these function calls are not documented.  Someone else on the forums may be able to help if they tried to implement something like this in the past.

  Good luck!

• How to synchronize a DSA Board (4496) with several S-series (6143) tips for PXI?

• External clock for PXI-6143

  Hello

  I'm trying to configure the PXI-6143 to use an external clock exported from a generator of arbitrary signals (PXI-5412). I followed the code example (Fgen DAQmx Synchronization.vi) and use one of the RTSI trigger for the export of the clock line, but could not make it work. When I run the attached code, it returned an error not saying not enough samples were taken by the task to HAVE it, but samples are returned correctly if I left PXI-6143 use its internal clock. Could someone point out what's not in this code, please?

  Thank you!!

  I think that I finally understand what has gone wrong...

  I did not indicate the event marker by the niFgen property node. Once I put in, the code works.

  Thanks for the one who never stopped!

• Point me to the example make a pulse 6225 Board + daqmx

  Looking for a book white/examples defining the terms of DAQmx digital signals for a trivial vi which runs by hand at MAX. All I want to do is use the terminal PFI4 on a pci-6225 map to generate a pulse of 100us. There are a variety of choices to generate a pulse of PFI4, but my choices keep getting rejected at compile or run time as inappropriate for the selected mode. There must be some examples like that, right? I shouldn't be looking the correct terms.

  TIA

  Alex

  Hi Alex,

  The following link has some general info on configuring DAQmx applications: http://www.ni.com/white-paper/5468/en/

  There is also useful information contained in the help for the DAQmx writing VI: http://zone.ni.com/reference/en-XX/help/370469AA-01/lvdaqmx/mxwrite/

• Current minimum for pxi-2529

  Hi all! I have the PXI-2529 matrix, and I intend to use it this way: I have a set of magnetoresistifs sensors connected via matrix switches to DVMs (see photo). I need a few times (such as 1 - 100 times a day) to change these connections. Here's the question: one of the parameters of the matrix is common minimum and it is 10uA. I want to understand what is the reason for this setting? (is this leak or something else), and what is that means that the matrix will not work if DVM internal resistance will be large enough, and current jet matrix mixers will be less than 10uA?

  

  Hi store,.

  To answer your questions, yes the minimum current is very similar to current humidification, this is the current that is needed to systematically knock the junk of the relay to check that it continues to work properly.  Using switches OR defines the minimum current as "the current minimum" which can flow reliably through the switch  So, while you will probably be able to measure a signal, even if you're not fulfills the minimum requirement, we cannot guarantee behavior of your switch if you operate out of specifications.  If you're running the specification current minumum for long periods of time, the resistance of the relay contacts will increase over time, and your relay will eventually become unusable.  Essentially, by non-compliant to the specification, you will shorten the life of your relay.

  As for your question, "is to say that after a few years of this matrix using the conductive oxide become big enough and I'll lose the connection?"  The answer is Yes.

  I hope it's a bit more clear, let me know if you still have questions about that though.  Have a good!

• Pinout for PXI-2535

  I have to build an advice for the PXI-2535 connect signals instead of using the terminal blocks. I can't find the correct manual however. Can someone you will find descriptions of stitching of connectors 68 pins for the PXI-2535 switching matrix.

  Thank you

  Walter

  Hi Walter,

  I believe that the desired pinout is in aid of switches of NOR.  This manual is copied to your machine if / when you install the driver OR-SWITCH.  It can also be downloaded from the following page: http://digital.ni.com/manuals.nsf/websearch/B133DDD29F0DFCC28625746E00564E56

  

  Let me know if you have any other questions!
