Problem of discovery of the cDAQ-9191 in MAX

Similar Questions

• My NOR cDAQ-9191 is over the display of the module installed in MAX.

  I just bought a 9191 cDAQ chassis with the NI 9219 AI module.  MAX initially showed the long-9191 9219 under network devices.  However, after several hours of messing around with the wireless settings and by pressing the reset button several times, MAX no longer displays the 9219.  Nothing dramatic happened to the hardware (that is, it was not dropped or mishandling), so I suspect a problem of self-inflicted free software.  The technician OR I have recommended 'Reset Configuration data' Max, I did, but that didn't fix it.  Has anyone else had this kind of problem?  Any suggestions?

  problem solved... several network services OR were stopped.  The module will appear once I restarted the service.

• buffer size and sync with the cDAQ 9188 problems and Visual Basic

  Hi all, I have a cDAQ-9188 with 9235 for quarter bridge straing caliber acquisition module.

  I would appreciate help to understand how synchronization and buffer.

  I do not use LabView: I'm developing in Visual Basic, Visual Studio 2010.

  I developed my app of the NI AcqStrainSample example. What I found in the order is:

  -CreateStrainGageChannel

  -ConfigureSampleClock

  -create an AnalogMultiChannelReader

  and

  -Start the task

  There is a timer in the VB application, once the task begun, that triggers the playback feature. This function uses:

  -AnalogMultiChannelReader.ReadWaveform (- 1).

  I have no problem with CreateStrainGageChannel, I put 8 channels and other settings.

  Regarding the ConfigureSampleClock, I have some doubts. I want a continuous acquisition, then I put the internal rate, signal source 1000, continuous sample mode, I set the size buffer using the parameter "sampled by channel.

  What I wonder is:

  (1) can I put any kind of buffer size? That the limited hardware of the module (9235) or DAQ (9188)?

  (2) can I read the buffer, let's say, once per second and read all samples stored in it?

  (3) do I have to implement my own buffer for playback of data acquisition, or it is not necessary?

  (4) because I don't want to lose packets: y at - it a timestamp index or a package, I can use to check for this?

  Thank you very much for the help

  Hi Roberto-

  I will address each of your questions:

  (1) can I put any kind of buffer size? That the limited hardware of the module (9235) or DAQ (9188)?

  The samplesPerChannel parameter has different features according to the synchronization mode, you choose.  If you choose finished samples the parameter samplesPerChannel determines how many sample clocks to generate and also determines the exact size to use.  But if you use streaming samples, the samplesPerChannel and speed settings are used together to determine the size of the buffer, according to this excerpt from the reference help C DAQmx:

  

  Note that this buffer is a buffer software host-side.  There can be no impact on the material available on the cDAQ-9188 or NI 9235 buffers.  These devices each have relatively small equipment pads and their firmware and the Driver NOR-DAQmx driver software transfer data device to automatically host and the most effective way possible.  The buffer on the host side then holds the data until you call DAQmx Read or otherwise the input stream of service.

  (2) can I read the buffer, let's say, once per second and read all samples stored in it?

  Yes.  You would achieve this by choosing a DAQmx Read size equal to the inverse of the sampling frequency (during 1 second data) or a multiple of that of the other playback times.

  (3) do I have to implement my own buffer for playback of data acquisition, or it is not necessary?

  No, you should not need to implement your own stamp.  The DAQmx buffer on the host side will contain the data until you call the DAQmx Read function.  If you want to read from this buffer less frequently you should consider increasing its size to avoid the overflow of this buffer.  Which brings me to your next question...

  (4) because I don't want to lose packets: y at - it a timestamp index or a package, I can use to check for this?

  DAQmx will meet you if all packets are lost.  The default behavior is to stop the flow of data and present an error if the buffer of the side host DAQmx overflows (if, for example, your application does not pick up samples of this buffer at a rate equal or faster than they are acquired, on average).

  If, for any reason, you want to let DAQmx to ignore the conditions of saturation (perhaps, for example, if you want to sample continuously at a high rate but want only interested in retrieving the most recent subset of samples), you can use the DAQmxSetReadOverWrite property and set it to DAQmx_Val_OverwriteUnreadSamps.

  I hope this helps.

• the cDAQ-9188 discovery method?

  I have a cDAQ-9188 I prepare for use by customers in the area.  These customers tend to forget IP addresses, and I would like to add something to my request to help.  Something installed "NI Network Browser" on my development machine.  I suspect it was DAQmx 9.2.2.  This browser appears to be a shortcut to a web page of Silverlight being served off port 59648.  The browser does a good job to list the chassis on the network, and I would like to know if there is a way to make this work in LabVIEW.  It uses UDP or something?

  I know that the standard method would be to ask clients to use the network browser, but I'll try match the SCXI-1600 user experience where you just plug in and it appears.  I try to avoid making them run MAX or a browser or anything but my request.  I know that I can avoid the MAC with the VI DAQmx step add network device, but he wants an IP address for an entry.

  Thank you

  Hi Dan,.

  The API for the system setup OR was released earlier this year and aims to provide developers the ability to integrate MAX features into their distributed LabVIEW applications.  The following code uses the API and should be a good starting point for what you need to do:

  

  If you have any questions or encounter any problems do not hesitate to post back!

• Difference between the cDAQ-9174 and cDAQ-9178

  I have several cRIO-9081.  Each cRIO-9081 running NOR-DAQmx 15.5.  On four of the cRIO-9018 we show you cDAQ - 9178 with 8 modules.  Everything just worked.  On the fifth cRIO-9018, we tried to connect a cDAQ-9174.  The aircraft appeared in the Windows Device Manager and MAX, but MAX has indicated that the aircraft was missing (error-88705) and that Windows can't find a driver for the instrument.

  We then plugged a cDAQ-9178 in the fifth cRIO and everything just worked.

  What is the difference between a cDAQ-9174 and cDAQ-9178 other than the number of the module support?

  Hi Paul,.

  It seems it could be a driver problem! What DAQmx version you have installed on two computers? Reinstall the latest version may be worth it because it looks like there may be corruption. You can find the latest version here: http://www.ni.com/download/ni-daqmx-15.5/5901/en/

  You can manually associate the device driver, here: http://digital.ni.com/public.nsf/allkb/5B80CAAA64413B4C86256C5E0000C1A7

  There are modules connected to the cDAQ chassis?

  Also, sometimes, this can happen if you do not restart your computer after the installation of the NOR-DAQmx driver. Restart your computer after the driver installation will allow you to reserve the device successfully. Here are a few others not to try:

  • Check the charger to device OR to see if it is running
  
  
  • Reset the service OR charger
  
  
  • Reset the MAX Configuration database
  
  
  • The system power cycle

• The transition of the cDAQ to cDAQ ENET USB

  Hello community,

  For some reason, I'd probably change some of the cDAQ USB chassis that I use for the Ethernet frame cDAQ base. I already have some applications developed on the platform of the USB and I was wondering how painful (or even at all) migration from USB to Ethernet. I guess also assign an IP address to the chassis and set it up in MAX, it should be relatively easy.

  It would be nice to know about problems I can cope.

  Thank you.

  As far as I saw, just that everything is set up in MAX, and then it is homogeneous in all of your applications.  You may need to remove all instances of your USB cDAQ located in MAX in order to reuse the virtual name.

• Networking the cDAQ-9188 - no 'network devices' Max

  Hi all:

  I have problems connecting my NI 9188 cDAQ via ethernet to my computer. MAX does not display it in his repertoire, or it displays "network devices". Based on the guide NOR offer, I don't know what else to do (I can't access the modules in a LabVIEW project which is my problem).

  I used the tool online browser that seems to be the equivalent of MAX and works very well - I can see the IP address of the controller and it shows what chassis slots are used by what the map.

  I tried manually inputing this IP in a remote system to the MAX, but that hasn't worked.

  Any ideas on how I can networks controller on my computer so I can actually use in a LabVIEW project.

  I have LabVIEW 2012 32 Bit. Would a student version be the cause of the problem?

  Thank you very much.

  I am familiar with the method you describe, but I agree with all the power cycling to get some of these products to work. I had to do this several times with the cRIO. Any chance you could give a little more than a description step by step explcit of your approach? Thank you!

  Good so here's what I did to try to reproduce and to have a step by step of what I had to do.

  Firstly I have reset my cDAQ so that it would be if all goes well in the mode that yours is.  To do this, I pressed the button to reset for 5 seconds then.  I have also all my network devices defined to "Obtain an IP address automatically" in the IPv4 settings in my network connections.

  After that, I start MAX.

  Go to devices and Interfaces > network devices, then I right click and choose Find devices.  It took a lot of time and the list was empty, but then I noticed that while he was always looking in this window, the MAX window showed my cDAQ-9188, who was a white device.  There, he registered the IP address as 169.254.93.149.  At this point if I went to the device to the MAX I saw where he sometimes States under network settings that no network adapters found.

  So I closed MAX and open my "view network connections" in Windows, I just searched that term in the start menu.  Then for my device properties, went to the IPv4 properties, set the IP address of 169.254.93.0 with 255.255.0.0 default gateway.  It is, so I'm on the same subnet as the appliance.

  I then restarted MAX now when I go to the device under devices, network and network settings I can set static IP and subnet is 255.255.0.0 10.10.10.100 then save.  Then closed MAX.

  Then I went back to my view network connections, the static value of what I really wanted is 10.10.10.0

  MAX then launched.  Find my device that is always white, click Add the device.  And then all is good.  I don't know if all these steps are necessary, and I don't know if there is an easier way, but it worked for me.

• cDAQ 9191 and neither 9215

  CDAQ 9191 or NI 9215 there a fpga module that we can program?

  Is it possible to perform mathematical operations with the signals that we gain by using cdaq 9191 and NI 9215?

  Once the 9191 is set up in MAX, you can read the channels on the 9215 and do what you want with the data.  The 9191 is used only to transmit data from the 9215 on a computer that is running LabVIEW, where you can perform mathematical operations.

  If you want or need FPGA, you get a compact chassis of RIO, not a compactDAQ chassis.

• Cannot delete the cDaq MAX devices

  I got a new device cDaq today and plugged into pc.

  It appears in MAX as cDAQ4 as I have already had 3 more before all shipped to a customer.

  The question is how can I delete the old ones on MAX.

  If I choose to remove by a right click or button on a panel of MAX, he asked me if I would like to remove it but nothing happened after that.

  I could remove devices in a chassis in this way, but not the frame itself.

  I tried to restart MAX after that and the devoces are still there. Did not attempt to restart the PC again, but don't think it would help.

  What is the solution of this problem.

  Hi Sergey,

  Is - this never happened to you before? What version of MAX, DAQmx and which OS are you using? If it's Windows XP, have you recently installed a Service Pack? Here are a few steps you can try:

  (1) open the Task Manager and ensure that there are no running LabVIEW or VI applications, that is sure to try to communicate with the device (although you would your cDAQ unplugged from your PC in any case)

  2) go to add/remove programs in the Control Panel, down to National Instruments software, click on edit, select the DAQmx driver and click on repair.

  (3) then try to remove the cDAQ, it can work.

  Otherwise, it could be a corrupted Max database, in this case you can follow the steps described in the following KB that you will guide them in creating a database MAX: How can I clean corrupted MAX Database and start with a new One?

  Please let me know if one of these help to solve the problem.

• Automating discovery of the network in Windows 7

  Hello

  I use Windows 7 Ultimate. The problem is when I go to network it keep ask me ' network discovery and file sharing is disabled. " Click here to change. " 

  It is so annoying to always click on that and select Public or private profile.

  I put the SSDP Discovery service to start automatically, but it is not affected Network Discovery Service.

  It is in the firewall exceptions.

  How to set or configure the network discovery so it starts automatically when the PC starts every time?

  Also

  I want to stop computer remotely.

  When he does it disables the network discovery because of Security Issues (Sounds like IP-Sec or something totally unaware of it). I want to turn it off or want to add Exception since it is linked only in the private network.

  Add Exception or lower security on off the computer remotely?

  Hello Chetan,

  I'll be happy to help you with the problem you have with the computer. I understand the frustration when things do not work as it should.

  I created:

  1. policy - network discovery - network - here I added networks, area and actions (see the user host application)

  2. policy - network discovery - users - here to add all protocols

  Created:

  3. policy - access - rules (only default discovery use) control

  How I understand for the first time that all the. But the system cannot find the users (is to find only the users that use the FTP)

  Maybe it's need to use NetFlow devices? What I am doing wrong? Thank you!

  Hello

  Network discovery discover hosts and applications, but this cannot be used in the strategy of access control for the rules of the user in function.

  The primary use of the network discovery is for IPS recommendation firesight political and awareness on user data in firesifght.

  For access control strategies, power of fire must have mapping user ip based on which it can apply the rules.

  You need user agent, who can get the IP of the user mapping, and then this whole config on the firepower that will work parallel to that.
