• SCXI-1160 with 'DAQmx switches Open Relays.vi' list of syntax of relay.

  Hello

  I re - write a request for a RT PXI controller that handles of many SCXI-1160 relay cards. We want to abandon traditional DAQ to DAQmx. I don't have the controller with me and I would like to know the syntax to use in the list of relays for the 'DAQmx switches Open Relays.vi". I want to use this VI as a command "several relays. I did a lot of research without success.

  I need the syntax that take into account several chassis, several cards, relay and individual relay range.

  Any help?

  Thanks in advance.

  Hello Michel,

  Sorry for this confusion.

  You can find some general examples for switches of programming under help > find examples in LabVIEW.  I would go to the output material & > DAQmx > switches and check out some examples below to see if any programs already exist for your goals.

  As for your specific question, at the beginning of each program, you must DAQmx switch topology Set and Reset.  This allows the users to define the topology of the switch for each individual switch card in a chassis.  A good community it shows a simple, you will find a complete example of using these two screws, we discussed here.

  Finally, the SCXI-1160 is an electromechanical lock change, so in the case of a power outtage, the switch will retain its State.  However, switching on, all default relay to their States normally connected.

  Thank you!

• How to synchronize the start of IT and relaxation the Scan list (DAQmx Switch)

  Hello

  I want to measure samples of N to the AI0 of Council NI PXI 4461. The measurement starts on a rising edge of a digital triggering provided to the PFI0 of the same Board. The measure is configured with samples of N/2 pretrigged. So far, everything is under control...

  Using an NI PXI 2567 Board, the signal applied at the entrance the 4461 (AI0) switches between a V2 and V1 signal. I would like to synchronize the switch between the two signals with the trigger signal applied to the input of the PFI0 Governing Council 4461. In order to obtain samples of N/2 of V1 and V2 samples N/2. Synchronization of 1 to 5 ms would suffice!

  My question is how to synchronize the start of acquisition of AI pretrigged of 4461 with the switch control given by the Council of 2567?

  Thank you in advance for your help...

  PS: the configuration of the system is:

  -LabView 8.5

  -Chassis PXI-1044

  PXI-4461 on slot 2

  Module 4-slot PXI-2567

  Hi Frederic,.

  I came back to this recently and used the following examples to run the desired synchronization.

  PXI-4461: Acq & graph tension-Int Clk - dig Start & Ref .vi

  Samples per channel = 1000

  Rate (Hz) = 10000.00

  Start the trigger Source = / [name of the instrument DAQmx] / PXI_Trig0

  Onboard start = fall

  Reference Source Trigger = DAQmx Device Name] / PXI_Trig0

  Reference edge = fall

  Trigger samples = Variable (100, 500, 900)

  PXI-2567: Switch Scaning-SW Trigger.vi

  Advance the output terminal full = / [name of the instrument DAQmx] / PXI_Trig0

  Scan list = / [name of the instrument DAQmx] / ch0-> com0.

  Scan list = / [name of the instrument DAQmx] / ch1-> com1;

  Hardware configuration:

  The PXI-2567 module controls an external relay that switches between the voltage of 5 V on ch0 and ch1 0 V.

  The PXI-4461 connects to the COM of the external relay and therefore reads 5V when ch0 is connected; 0 v when ch1 is connected.

  Procedure: The above examples are used in the following procedure.

  1. run the PXI-4461 VI.  A start trigger (falling edge) is necessary to start collecting samples before firing.

  2. launch the module, PXI - 2567 VI.  When ch0 is initially (and immediately) on com0, a trigger is sent to PXI_Trig0.  The PXI-4461 will begin to acquire samples before firing.

  3. - click on the "Connect to the next" button on the front of the PXI - 2567 VI module.  This sends a trigger to entry software for the PXI-2567 module and the transitions of the scan for ch1-> com1 list.  Once the PXI-2567 module remains (debounced), advanced complete relaxation is sent on PXI_Trig0 for the PXI-4461.  The PXI-4461 will begin to acquire samples after outbreak.

  Note: Instead of the trigger of the software entry, an external input trigger can be used (e.g. PXI_Trig1).

  Results:

  > Before instant release of samples = 100

  Delay is caused by the time of actuation of external relay.

  

  > Before instant release of samples = 500

  Delay is caused by the time of actuation of external relay.

  

  > Before instant release of samples = 900

  Delay is caused by the time of actuation of external relay.

  

  I hope that the attached screws and the explanation above helps you and/or other customers who have this problem.

  Best regards

• Handshaking DMM with multiple switching devices - DAQmx error

  Hello.
  I am trying to create a loop of the handshake with DMM (PXI-4071), SWITCH (PXI-2569) and MUX (PXI-2575). The three instruments are in segment 2 chassis PXI-1045 (locations, 8, 9 and 10) and I use the ways of PXI trigger in the triggers of the route.
  I followed the article NOR 'Multimodule Scanning with National Instruments switches' - I modified the example NI SWITCH "niSwitchDMMSwitchHandshaking" to set up another SWITCH, but when I tried to run the example, I got an error:
  
  0xbffa6b9a - no lines recorded could be found between the device in the road. (screenshot pop up is in the attachment). It is the function of niSwitch_InitiateScan to the second switch that returned an error.

  PIX trigger change has no effect.
  I tried the CVI and LabVIEW examples with the same result.
  I even tried to use two 2575 MUXes - same result.

  Can someone tell me what I am doing wrong?

  Hi Pavel,

  I checked that the component that controls the routing of the TTL for the PXI is included in NOR-DMM 3.0.2 (latest version as of 06/14/2010).  NOR-DMM 3.0.1 contains an older version of the TTL routing code and will therefore place several comprehensive lines scanning advanced on the same trigger.

  Unfortunately, the component which controls TTL routing is one of the constituent elements of the software installed OR lower, and thus we do not expose it to the user.  For that to work, we would need to uninstall almost all the software components of NOR, which is a major undertaking.  Here's what I recommend instead:

  For now, we will Garland triggers one switch to another.  This will allow us to start development in OR-Switch; as soon as OR distributes a program, you simply change the triggers as they all point to the same TTL line.  This will allow switches to operate in parallel rather than in series, and the passage of the switch of your project can run faster.

  If we have to absolutely exploit the switches at the same time, I would recommend either uninstall all software of OR or get a machine with a fresh install of XP and then install not newer than 8.9.5, OR DMM 3.0.1 DAQmx software and NI - Switch3.8.

  As I mentioned earlier, NEITHER is aware of breaking backward compatibility and we are committed to reintroduce the old features in a future release of the pilot.

  Keep this thread bookmark and post back in a month or two and I'll let you know if we have any updates.

  Have a great day!

• How is it that a computer which works very well with a direct Ethernet connection won't work with a switch, however any other computer using the same port, cable, ect, and so on, can?

  Switch issues. Help, please.

  How is it that a computer which works very well with a direct Ethernet connection won't work with a switch, however any other computer using the same port, cable, ect, and so on, can? We already checked the firewall as a question, that it was not, and now, we are puzzled.

  Well, I know that the issue is long-term... believe me, it's a long, but as they say, the devil is in the details. Anywho, the question is, my grandfather has a HP laptop, which for two years has been able to run through a Linksys switch to his router and connect its printers to his laptop. About two months ago it suddenly doesn't work like that. Now, it works fine if it plugs directly into the router/Ethernet. My uncle suggested that the switch was bad, but after testing the same port, cable and all, the switch worked well for him. ' GRAMPS really needs this answered, but someone else, it is called can not understand and now I, in turn, ask you all for what you can offer. Here are the ideas that we have already discredited.

  -Switch bad: as above, is that this particular laptop, even under identical conditions, the works of my uncle very well.
  -Bad NIC: debunked through the fact we connected to the computer directly to the router and it worked fine.
  -Bad configuration of the firewall: we have disabled the firewall (please do not notice, he wasn't the smartest idea, we already know) and even if she recorded the switch exists, the internet is always triggered when you are connected with the switch.

  Thanks in advance for any assistance that you can provide and Merry Christmas to you all.

  It would be useful to consult the results of the ipconfig/all command both when it is connected to the switch and when it is connected directly to the router.  In addition, what is the model of the switch?

  To save the manual copy and the new hits of the ipconfig/all command output-

  First connect through switch.
  Open a command prompt window (start > run > cmd > OK)
  Type the following lines in the black command prompt window and press ENTER after each line

  echo "Connected via the button" > "% UserProfile%\Desktop\ipinfo.txt".
  ipconfig/all > "% UserProfile%\Desktop\ipinfo.txt".

  Now connect directly to the router, type the following lines in the command prompt window and press ENTER after each line

  echo "Connected to the router" > "% UserProfile%\Desktop\ipinfo.txt".
  ipconfig/all > "% UserProfile%\Desktop\ipinfo.txt".
  Notepad '% UserProfile%\Desktop\ipinfo.txt '.
  output

  Copy the contents of the Notepad window in your response (if you use the laptop when it is connected directly to the router) or close the Notepad window, and then copy ipinfo.txt of the laptop to the Gramps in a USB FlashDrive you can connect to any computer allows you to answer.

  You can delete ipinfo.txt on the desktop when you are finished.

  Get the message "This Mac cannot connect to iCloud due to a problem with my Id, open Preferences to solve iCloud iCloud" after entering my password which is accepted and then after a minute or two messages is.

  I'm your pain ptapp!

  Through my research for an answer that solves this problem, I have found that not even Apple knows how to solve this problem of password to iCloud.

  All 4 of my devices constantly ask my password because of some problems with xyz account.

  Then I enter the password only to be told that iCloud cannot check my password.

  Then after several repetitions of this I get locked and have to go to the site apple id to change my password.

  I didn't spend $6 000 on these beautiful devices so I could spend countless hours dealing with support (with no positive result) and find themselves just beyond myself in frustration. I have a Mac Pro, 2 iPads, 2 iPhones and an iPod touch. All are behaving this way, no matter what it is I'm doing at the time.

  Apple needs to fix this problem, if they have any idea how to.

• cRIO-9074 ethercat with a switch/hub between the cRIO and slaves

  Hi, I have a cRIO9074 I'll use 7 JVL EtherCat Mac800 motor control.  Engines are fairly spaced, so I use a switch of CU2005 EtherCat Beckhoff 5 ports between the readers and the cRIO with 2 motors in series on three legs and a motor on a port by itself.  My problem is that labview will not find all engines unless one of the ports on the switch motor is plugged, or a line of engine is connected directly to the port ethercat cRIO.  He has no problem see two engines on the same line, it just will not see one of them if more than one line of motor is connected to the switch ethercat.

  Thus, HALP!
