• Questions about the work in real-time

  Hello.  Just a few questions on usage in real time, in fact on the swf file.

  First of all, I want to create something of a drag and drop interface.  Is it possible to have a stage act as two separate steps?  I mean, is it possible to have the left side of my step hold all the components, they are moved to the right side of the scene and placed anywhere, the user can then click on save, and only the right side of the scene is saved?

  Secondly, I'm testing a few things.  What I would do to get a type of free transform on an image on the stage in real time, in the swf file?  So once the movie is played, the user can resize any image then how they like by dragging a corner of the image...

  Cheers for any advice.

  You can use 2 container (Sprite or MovieClip) objects one on left on the right.  All display list container objects have their own scene

  jou can so easily the steps as much as you want each independently controlled placed anywhere you want.

• Controller time real-time FieldPoint or Ethernet interface

  Good afternoon

  The first feature listed on the PS-2000 product page is:

• Stand-alone embedded real-time controller or on PC distributed i/o Ethernet interface.

Everyone was able incorporate a PS-2000 as an Ethernet on PC distributed i/o interface?  In other words, have the PS-2000 as a FP-1600 Act?

There are some discussions forum discussions that dance around the subject, but I found no really one who responds to her.

Thank you

Ed

Hi edlad,

After playing with a FP-2010 for a while, I think you need to install LabVIEW Real-time on the controller to make it work, even though you are technically not to use it because you are not running a VI/executable on the controller. Regarding your problem with the installation of LabVIEW 8.5.1 on a PS-2000, it is disturbing because it should not be a problem that at all. In fact, I have personally been able to install LabVIEW 8.5.1 on many FP of the 2000s. For that matter, I suggest reformatting of the PS-2000 of MAX and try again.

ThinkG: Regarding your question on the use of a PSC-2220 to connect with belvedere, I don't know because the support of Lookout is managed by our subsidiary in Shanghai by e-mail only. However, I don't know that you can use this second ethernet port to connect with another network (cFP-180 x) FieldPoint module using the FieldPoint drivers. Here are some good articles about this configuration knowledge base. I hope they are useful.

  Hi emc2006

  I'll answer your questions separated by your topics:

  1 - What is the factor that you want to compare between these two products? In the link below, you will find the performance of the NI PXI-5660 RF Signal Analyzer system.
  2. you can develop this feature of programming in software Application development, i.e. of LabVIEW.
  3. Yes, NI´s vector signal Analyzer could run preconformite or EMC compliance analyses. In the same link below, you will find in the subdivision of Applications.

• Need information about memory in real time

  Hello

  I use sbRIO 9633. I save data in the memory of the sbRIO (via ftp), as well as on the C drive of my computer (via an executable).

  My questions are,

  1. when the RAM is emptied (in other words, I take the target), the details logged on the sbrio via Server ftp does not get emptied. Therefore, when you connect via ftp, which part of memory are stored data? What happens if the memory is full? (as the application should work for years)

  2. that the application runs continuously, the bytes available on the real-time target decreases permanently (I guess) and finally RAM is full. So, do we not have to empty the RAM from time to time?

  3. If I do not add the loop of the newspaper on the RT vi, will decrease the "available bytes" on RT target? If not, then how?

  Hope that my questions are clear.

  (1) NEITHER sbRIO 9633 has 256 MB of memory persistent which is used by the ftp... should be easy to fill, so check the case 'out of memory '.

  (2) NEITHER sbRIO 9633 has 128 MB of RAM and you should read the FreePhysMem property when your application is loaded and determine a threshold to know when it's time to free the memory.

  (3) this can be done by the host (PC), by logging system (ip target) required.

  In my case, the memory used by the network flow increases over time, and I trigger to reset the stream to release the RAM.

• Rotary decoder in real-time and 'pulse shifter '.

  Hello world

  I'm putting in place a rotating decoder for use as a shifter of pulsation by labview real-time.

  Basically, this means I have two input channels (ttl-legumes, ~ high 20us) rotary engine. A channel contains a pulse at each CA (angle cranc) ° up to 12 kHz (increment). The other channel contains a pulse every 720 ° CA (the charge cycle, BDC_cc low break-even point). With this information a pulse to be generated on an output also channel ttl (high), which triggers my setup of measurement. This impulse must be moved in a programmable relationship to the entrance of BDC_cc, which aims at a table of regular measure.

  I got it running by streaming the channel of BDC_cc until a rising edge is detected, then count the edges of increment to the designated trigger point and then generate a pulse on the output channel. The problem is that the late 70-120us exit trigger. In short it's too; a maximum error of ~ 20 is acceptable. Digital channels appear to work faster, so I put discarded Counter-based acquisition.

  I'm quite new to LabView, so I'm sorry if the answer is obvious...

  My purchase setup consists of:

  PCI-MIO-16-1

  BNC-2120

  LabView 12.0
  Max 5.3.1f0

  Widows XP

  This configuration seems to exclude some options Labview offer, such as the external digital acquisition sampled or externally triggered by the acquisition in the base. A manual interpretation of analog inputs is way to slow.

  I have attached my working version.

  Any input appreciated woud...

  John,

  I only have a minute right now, but think I can play with a device simulated tonight or tomorrow.

  I'm quite sure that there would be a clean solution clocked by material if you use a series M or X-series

  Council MIO, but the older generation counters timers on the set of the E series do support everything which

  You need.  It's been a while since I had to rely on this generation of hardware.

  I think the basic approach is to use the lunatics of angle as the clock pulse train that defines the

  delay time of the pulse you want to generate.   You could be "Timer" the pulse based on the real

  angular position, helping you synchronize to a specific angle of crank.  The question is whether and how E-series

  counters of takes to support the generation of pulses triggered (or redeclenchables).  If they are not, I would say that you consider

  get new hardware DAQ which support this kind of trigger and you give a very precise pulse

  implementation.

• Continuous data acquisition and real-time analysis

  

  Hi all

  It is a VI for the continuous acquisition of an ECG signal. As far as I understand that the analog read DAQmx VI must be placed inside a while loop so it can acquire the data permanently, I need perform filtering and analysis of the wave in real time. How I implemented the block schema means that data stays int the while loop, and AFAIK the data will be transferred on through the tunnels of data once the loop ends the execution, it clearly isn't real-time data processing.

  The only way I can think to fixing this problem is by placing another loop that covers the screw scene filtering and using some sort of registeing shift to transmit the data in the second while loop. My question is whether or not it would introduce some sort of delay, and weather or not it would be supposed to be the treatment in real time. Wouldn't be better to place all the screws (aquicition and filtering) inside a while loop? or it is a bad programming practice. Other features I need to do is back up the data I na file, but only when the user wants to do.

  Any advice would be appreciated.

  You have two options:

  • A. as you said, you can place the code inside your current while loop to perform the treatment.  If you're smart, you won't need to put one another while loop inside your existing (nested loops).  But it totally depends on the type of treatment that you do.
  • B. create a second parallel loop to perform the treatment.  This would be separate processes to ensure that the treatment is not obstacle to your purchase.  For more information, see here .

  Your choice really depends on the transformation that you plan to perform.  If it's much the processor, this could introduce delays as you said.

  I would recommend that you start at any place in the first loop and see if your DAQ buffer overruns (you can monitor the rear of the buffer during operation).  If so, you should decouple the process in separate loops.

  In what concerns or not ' it would be considered as real time processing ' is a trick question.  Most of the people on these forums say that your system is NEVER in real time because you're using a desktop PC to perform processing (note: I guess it's the code that runs on a laptop or desktop?).  It is not a deterministic systemand your data is already "old" by the time wherever he leaves your DAQ buffer.  But the answer to your question really depends on how you define "real time processing".  Many lay it will set as the treatment of 'live' data... but what is "actual data"?

• Starting process in real time

  I have 2 questions related to LabVIEW Real-time. I'm using LabVIEW 2010 Service Pack 1. We have a PXI-8186 controller running the embedded real-time.

  (1) I have my software written to communicate using TCP/IP. The real time software runs the listener 'TCP create' then the 'wait on TCP listener"to look for the connections of the computer. This works well in the LabVIEW project. I then build the executable and deploy it in the system in real time, set up to run during startup. I put the target name to be my program name "Test program.rtexe" rather than "startup.rtexe". I don't know if that makes a difference. I saw the other files in the startup folder of the system in real time that have been named something else. My questions are: the name possible no matter what name we want and the system in real time all programs contained in the startup folder is running or is there another method to specify the programs to be executed?

  (2) is there a way to monitor or to see what programs are running on the system in real time? As the the Task Manager on a windows system. The reason I ask, is that after I restart the PXI system and without using the program of project, I can't connect to my test program running on the system in real time. I don't know if the software is running on the system in real time, is it established that the network interface which it was assumed, etc. to determine why I can not connect with him. Any help on various methods to determine if the software actually runs would be useful.

  Thanks for any help you can give.

  Bill

  Finally found the problem.

  It would seem that, at least in the 2 controllers shipped we have there, controllers have a flag in the BIOS that allows you to disable the file to begin execution on the system in real time. Once I put the flag on the 'NO', everything works. The flag is named:

  'Disable the boot VI' tab 'LabVIEW RT"in the BIOS.

  It is a good option if the boot VI is damaged or was not debugged prior to deployment.

• Control of data using multiple thermocouples via indicators and the waveform in real-time

  I apologize in advance for this question is probably a bit simple but I'm all new to labview and the forum and could use some advice. I have a CompaqDAQ with two 9213 16 modules of track and I'm trying to read in 30 thermocouples in a waveform, but also display 30 indicators so I can mark each indicator with the thermocouple for real-time tracking. Each thermocouple corresponds to a specific location and it is essential that the interface has an accurate indication or a label for each of them. I wonder if there is an easy way to do this in addition to split the signal and have 30 thermometers on my diagram? Perhaps a table any? If I use a table to create 30 thermometers, the DAQ assistant automatically sorts the thermocouples according to ascending numerical order. For example, would be the indicators of first and second on my interface automatically assigned to channels a0 and a1 of the first module, or should I do it manually? Even for the waveform?  Thank you very much!

  PS - Do not know if this message had need of more details, but let me know if more information is needed, and I'll give you!

  I see that you use the DAQ Assistant to create your task.  Now I understand why you may have about labelling.  It is easy of the seller NOR spiel booting...  But in any case, you already have a task to the MAX instead of use the DAQ Assistant?  The interface is similar and there may be a step or two, but your end application will be more effective and you will have more options with your data and properties.  For example, I tried to update the names of physical channel in the DAQ Assistant installation program, that it let you do, but it propagates that change forward to waveform chart legend.  Also, I don't know any property for this dynamic data type node, although I never use it either.  I suggest the setting up of your task and channels, Max if you'd give it a go.

  Since I thought I didn't really takes you all the way with you help, I wrote another one.  It uses a cluster, even if it's a bit barbaric.  I thought that there was a more eloquent way to do by changing labels, but I could not it works as I had expected.

• Convert a desktop PC to a target of VeriStand real-time

  Hello

  I have to convert a desktop PC to a target of VeriStand real-time.

  What are the PC requirements to convert the PC to a target of VeriStand real-time? They are the same as the requirements to convert a PC to a time target real LabVIEW?

  http://www.NI.com/white-paper/8239/en

  What is the procedure to install the engine time real Veristand to the RT PC? Is this the same as the procedure to install LabVIEW Real-time to a RT PC?

  http://www.NI.com/white-paper/2733/en/#toc4

  And what I have to install engine LabVIEW Real-time before installing engine VeriStand real-time?

  Last question: can I install the engine time real VeriStand on a PXI controller - 8115 Windows by creating a dual boot on my own? (PXI-8115 can be purchased with Windows or LabVIEW RT or the dual boot Windows/LabVIEW RT.)

  Thanks for your replies.

  Best regards.

  David

  (1) Yes
  2) kind of. Neither veristand engine is just an application that runs on the RT or windows. So once you follow this guide to make the target RT desktop computer you can install the NIVS motor application through MAX
  (3) Yes. Remember that the nivs engine can run on windows or RT so if the 8115 runs windows, you can run NIVS targeted toward you. If the 8115 runs RT you would need a separate windows PC and target the 8115 from that. Or you could put the hypervisor (if the 8115 supports) to simultaneously run windows and RT on the 8115 and so to run the client side NIVS windows targeting the engine on the side of the RT veristand... About a penalty of 50% of the performance

• Using FTPClient on a real time with system Exec.vi

  How can I tell FTPClient.exe address target when I start this executable with system Exec.vi in Labview?  I don't want to reinvent the file FTP utility used by MAX with targets in real time. I want to run this executable to a labview support utility without using MAX to do.

  Is this possible?

  Danny

  Thanks for the info.  Your "bad mood" response "suggests" a response to my question.  However, the full answer to my original question is that it is not possible to use FTPClient.exe outside MAX.  It is therefore not possible to spend in the address target at run time if the FTPClient.exe runs external to MAX.  FileZilla is a good choice - there are also other FTP clients out there, but you pointed out a solid choice.  Thank you.
