• What pins to use to receive the data from the PDS ELITE RS485 with the PXI-8431/2?

  Hello!

  I use the PXI-8431/2 to read data from the flow meter PDS ELITE (Modbus RTU). Receiving data, the RS485 protocol request to terminals 4 and 5, but this configuration does not seem to work. When I connect the RS-485 converter USB of Microflex I get the data correctly, so somehow between the PIN lay and PXI this problem there.

  Can someone help me?

  See you soon,.

  Hello Steven,

  I think that what was Hossein trying to send you is the following:

  How to connect and configure a device with RS-485 2-wire

  Can you also tell me a little more what you use to read the data? What environment. You have 2-wire or 4-wire Modbus RTU?

  Kind regards

• CanI set programmatically PXI-8431 half duplex ports (two sons)?

  Hello

  I use an NI PXI-8431/8 RS485 card for half duplex comms. I use configuration of the serial port baud rate usual VISA, etc., but I also want to set the port to two sons, no handshake.

  Currently I can do this from Windows, using the Device Manager, but it depends on someone who knows and not to forget to do. I want to automate so that it still occupies my entry into force, without worrying about who used it do.

  Can anyone suggest how I can achieve this?

  Thank you

  Hi Malcolm,

  You can set the thread mode and the type of control (handshaking) flow in LabVIEW using nodes of property.

  The article in the link below shows how to do this at the end to set the thread mode. If you duplicate the property node, you can choose Flow Control as property instead of the thread Mode.

• Read the PXI-8431 channels using LabVIEW

  
  

  Hi Marc,

  The examples provided with LabVIEW and DAQmx drivers are very detailed and comprehensive to demonstrate how you can use cards. To join the Finder of the example, start LabVIEW and select help > find examples.

  When you load the example Finder, make sure you browse by task.

  For the programming of DIO:
  Navigate to hardware input and output > DAQmx > digital measurement. There is a few screws. Make sure you look in the list of requirements to see the example works with the PXI-6515.

  You can also visit the following links to learn more about programming DAQmx:

  For series programming:
  Navigate to hardware input and output > Serial
  You will find most of the screw example it can be used with the PXI-8431.

  I hope that helps you to get off the ground!

• PXI-8431, without going into fashion with VB6 reception

  I use a PXI-1045 chassis with a PXI-8431 RS422/485 card and communicating via a VB6 program

  Send the output of the PXI-8431 RS485 module works well when it is in mode, the signal levels are approximately 1v and 3v for high and low, but when it is in fashion, that the outputs remain to 1v and 3v instead of going in passive mode and the two floating lines at approximately 2v with approximately 300mV differential as it should receive. This means that when remote devices send, the amplitude of the signal is about half as they compete with the PXI module and the center point of the two signals are 1v and 3v respectively. Our software does not receive the signals of the PXI module that is compatible with my theory, that it is always in the mode of sending and taking control lines, or maybe he's changed 4-wire.

  I swapped the PXI card and cards remotely with our good system and the problem will not move.

  I have eliminated ALL the material on the new ring by replacing it with a 67 on the way pin 9 connector plugged D directly Ohm resistor on the PXI card. With a scope, I can see that the new system will not in passive mode, but with the same connector the old system works OK.

  The only difference I can see between the 6 platforms old we who work and the new 2 that don't work is the new ones use the the NOR-XNET-PXI-8513 and the 'old' use the card CAN PXI_8464. This software would be in conflict? Are there any other updates to the software OR which could be causing it?

  Philip,

  3.5.1 series had some issues related to the read/write mode series 2 wires, I would recommend corresponding versions of driver with your working system or upgrade to the latest driver of series.

  Kind regards

• Resource name unique for each serial port 8431/8?

  Hi all

  I develop test applications using the NI PXI-8431/8 serial interface card.  Because I do not have the hardware, I'm not sure how it will recognize in NOR-MAX, and given that (probably), it will use the generic functions of the series VISA, I can predict no special configuration option (no special driver).  Each of the 8 ports on the map series will appear in NOR-MAX as it is the name of the own resource of individual VISAS, or I have to find another way to tell the difference between channels/ports?  Please notify. Thank you.

  They will appear as COM ports normal series.  Nothing special.

  Hi Alec,.

• I need estimated MTBF for a list of products

  Our system customer asked about MTBF.  So I need MTBF estimated for the following of PXI products: PXI-6509, PXI-6542, PXI-7813R, PXI-8431/8, PXI-8432/4, PXI-7953R.

  It is understood they are only estimates and will be accompanied by the creation.  A full calculation 217 is not intended or desired.  I got estimates of other systems of component suppliers.  How can I get these estimates of NOR?

  I did some more research on the calculation of MTBF numbers. In general, including this map, our MTBF is based on design, not fail rate field. The method used to determine this particular card MTBF was Bellcore question level II.

• RS422 PPS signal generation

  I am trying to generate a RS-422 PPS signal using the PXI OR PXI-8431/8, LabWindows/CVI and CVI standard library functions, but I can't find a way to produce a signal that remains HI with persistence for X number of ms.  I realize that use the PXI-6602 would be an ideal solution, but in my case, I am relying on the RT OS to maintain determinism.  Do you know a white paper or a thread that could describe a reliable way to do this with the functions of the ICB boards of series I have?

  This message has been copied since the LabView discussion Forum.  Sorry for the inconvenience.

  Sean,

  I've updated the functions of generation of pulse with those of the DAQmx library and am now running.

  Thank you a lot for the input.

• County to return read VISA does not match number of bytes

  I encounter an error with a VISA reading.  I ask 8 bytes (in number of bytes), but get only 7 return (return number), which causes errors in my code downstream.  Curiously, the VISA Read block does not return an error.  Any ideas on how to debug this?

  Data sheet:

  LabVIEW RT 8.2

  VISA 4.3

  Series OR 3.3.0

  PXI-8431/4

  Parameters: 1843200 Baud, 8N1.

  Is VISA reading set to put an end to the reception of a termination character?  I think that it does not have the stop in the output string character, which could make your short back counter.

• PXI unrecognized 8431

  I'm running a PXI Rack 1000 b with the Visa 5.0.2 version and version 4.6.1 MAX MAX in the PXI basket and DAQ cards are present, but in the Comms menu drop-down I can't see the 2 Port RS485 card and windows only gives a message on startup it is trying to find the "PCI Simple Communications controller" driver probably reason whuy is not present in the list of the Comms.

  I tried to remove the VISA and re - install also tried to reinstall MAX but no joy.

  Anyone have any idea?

  Thank you

  The card comes with NOR-Serial. You have installed that?

• Get information about the physical location (serial) Visa (slot) in PXI time real (Pharlab)

  Hello

  I PXI system with controller time real (OS Pharlab) and many maps series (about 6 cards).

  The maps in the series are two different models, which each contain several (8431/8 and 8421/8) serial ports.

  And the COM Port enumeration mix and I would like to know the link between COM numbering where it is linked.

  I have already dealt with a few methods:

  1. I've tried using the node property of Visa but he cannot know which card port COM belong

  2. I tried to use the Configuration Library system and don't manage to get general information of the card and not what ports have this card.

  3 try to fill you with the VisaConf.ini, but discovers that ASRL and COM Auto-enumeration is the same.

  4. I tried to look in NISerial.ini, NISerial.dbs and NOR - RT.ini and did not find any help here.

  Application engineer or support suggest to look in the registry of the operating system Pharlab because it is windows based and material information must be stored in the registry

  Further explanation on the problem of PXI enumeration:

  PXI produce enumeration auto for the ports series (COM3, COM4, COM5...) according to the card slot, but when there is a mix of the two models of the system would then list a model (8431) from 3 to 50 (6 cards and 8 ports) and the other model (8421) 51 to 98. so if I have 8421 in 2 and 8431 slot number in the slot number 3 it would list 2nd slot COM59 to COM68 and 3rd slot COM11 to COM19.

  Why not just use NOR-MAX to manually configure the ports?

  The system is essential and can not be stopped for a long time and he operated by people who are not very technical, so the customer who wishes to be able to exchange business cards without futher configuration.

  Thank you

  Hello

  I pxi-1044 with some pxi cards (pxi-4065 / 6509 / 2529 / 8431 / 8432 / 2576 (3 borads))

  and the pxi-8310 controller.

  When the system has been configured for the first time, it works well.

  but 2 of the borads (pxi-8432 / pxi-2576) must slot interchange (due to problems of space with their own, conectors)

  When the system power, both led (on pxi chassis) and together (led controller), but windows xp does not start,

  Led CONTROL switch to and restart the computer. over and over again.

  I remove all the advice and check that all are recognized through MAX except the two planks of switching.

  Change to a different location (never used) and the look of system work ok, pxi-8232

  this Council is recognized.

  What is the correct procedure to exchange some tips when MAX has a previos configuration?

  I would use the slot machines that I have problems with, is it possible?

  Thank you

• Using SMU 6612 to measure PXI-6528 pulsewidth channel - channel is not available.

  Hi all

  I use SMU 6612 card counter to measure the pulse width of the signals to PXI 6528 DIO card. These two cards are in the same chassis PXI (NI-SMU-1065). I could measure the pulse widths using the example LabVIEW 2013 Counter - pulse width of reading and (over) frequency example of .vi. However not all channels of the PXI-6528 map appear in the drop-down list of channels on the pulse width can be measured. Try to connect any other channel that those which are available in the drop-down list returns the error. On the PXI card port 6528 0,1 and 2 are entered ports and port 3-5 are output ports. I can measure the pulse on port 0, 3 width and line 0 port 1 and 4.

  Can someone explain to me why don't see port 1 or port 2 channels in the drop-down list or force the VI to measure the width of pulse on these channels?

  I can plug PXI-6528 external input channels SMU 6612 counter input channels and measure the pulse width, but if possible I'd like to avoid the external wiring between the 2 cards.

  Probably not.  Unless the routing plan is in fact reversed as it seems a bit sorta that.  As stated on my system, you can route * of * a port of entry * to * RTSI, or you can route * of * RTSI * to * one output port.  This does not make much sense to me, but that's what I see:

  

  If the routing card * is * reversed, your only likely workaround without physical wire would be to generate impulses in question of port 3.  It's pretty clear that 1,2,4,5-tetrachlorobenzene ports have no ability to interact with the bus timing, physical wiring would be the only option.

• PXI-1033 not detected until the pc is rebooted

  We have a chassis NI PXI-1033 with a PXI-5114 and PXI-4072-PXI-6221, fist, that he had failed to recognize and install drivers for motherboards. The search in the knowledge base, I tried workaround by disabling the PCIe mode ' bcdedit/set pciexpress forcedisable' command and rebooted the pc. Then the system recognized and installed the drivers for all the hardware.

  Disabled the PXI system at the end of the day. The next day, after activating the system, he did not recognize the hardware, returned changes to aid 'bcdedit/set pciexpress by default', then restarted the pc. Once again the material have been recognized.

  I tried to change the configuration on the PC BIOS, without success. The PC is an ACP-4000 of Advantech. We need to restart PC after a cold start so he could recognize the hardware and load drivers.

  Is this normal?

  Concerning

  The PC is under Windows 7 Pro. I searched on google for similar problems, where I found one where someone said that the culprit is that the chipset of the motherboard not give not the PCIe card delay what he needs on a start cold in order to be recognized. A reboot gives the time required and the card works.
