• Can I remotely from a computer that does not have control with LabVIEW?

  Hi, I have a PC at work that has LabVIEW (LV) installed, and I order several machines using a GPIB/USB interface. I would like to be able to control them remotely, at home, so I can start new experiences without having to enter in my lab. However, my PC at home isn't LV what are my options to achieve this?

  The most obvious solution is to use a software that allows me to remotely control the PC of my work, and then do that. However, it would be nice if there is an easy way to interface directly with LV. For example, something where he would create the VI as a Web page, and then I could see it in my browser to home or something. Is there something like this?

  What are my options to control everything from home, without LV on my PC at home?

  If "at work" is a reasonable society, there will be a firewall and it would be difficult to do anything without their approval. Connections to the internal network from external random places are usually blocked for good reasons. Talk to your first COMPUTER service.

  Assuming that you can connect to the remote computer, you can start reading here. Be aware that several modern browser (e.g. Chrome) is no longer support or allow NPAPI plugins, then your choice of browser style are limited.

  A better choice is direct on the remote control. This allows you to fully control the LabVIEW application, start it even if it is not active, loading/saving files, etc.

  I generally use Chrome remote desktop. I can connect to one of my computers from anywhere, even if both computers are located on networks private behind a NAT or firewall. Works great!

• Control with Labview instead of MAX PCI-1422

  Hello Experts,

  I need your help in one of my problem. I have a camera of sensors unlimited that is SU - 640 1.7 RT - D and a card parallel NI PCI-1422. I can use and acquire data with power MAXI of the camera, but I want to exploit, use and acquire images from the camera by using LabView. Is it possible to export or using the camera with Labview instead to write fresh code in LabView?

  LabView offers it all support or bed automatically PCI-1422 or any possible solution that I get the code for the use of this device block diagram in LabView.

  Please let me know, answer.

  For any help or suggestion will be highly appreciated.

  Thanks in advance!

  Hi David,

  You can use the function IMAQ write file to record the images to the disc. Please see the link for an example below.

• Maxon motor control with LabView

  Hello everyone, I'm new here and I tried to find out how this process of work for some time and I ran out of options. LabView is very difficult to understand.

  I'm about to order a controller epos Maxon motor 24/5. I have a vi that does what I do, but I need to find a way to make the process faster. Basically will control a wing that goes forward and backward at very high speeds. I'm not sure what I should do, I would also like to generalize the process by a power enter a function or a wave of the position of my choice. If any of you all can help me it will be greatly appreciated. Thanks in advance.

  CarlosUT,

  Without the subVIs Epos, it is difficult to say where downturns could be.

  Take into account:

  1. the mathscript node is probably much slower than native LabVIEW, special code for what looks like a logic very simple.  Replace with the range of comparison functions.  Also consider the feedback node initialization so that you know where it starts when the VI is called.

  2. learn a few basics of data flow. Your delay (ms) and judgment is read only once at the beginning of the VI and these original values are passed to the loop. Any subsequent changes to these values will not see inside the loop. Move the terminals in the loop.

  3. double code: you have the same Subvi in each case in the structure of the case. Move the Subvi outside the structure of the case and simply use the box structure to choose which set of values will be used.

  4. given that the minimum value of the delay (ms) is 150, the loop cannot run more than about 6 times per second.  You don't specify what you mean by high speeds for the control of the wing, but this may be a factor.

• VisualAnalog control with labview

  Hi all

  We bought an AD9643 that came with an FPGA based FIFO capture Board of Analog Devices, since they are just called VisualAnalog software to read the data and the control of the Board of CDA. Can I manage control this software under Labview?

  We just need to make easy control as start, stop and get the data.

  I tried the ActiveX method, but when I try to insert the ActiveX object, may not find all related objects.

  Hey Martin,

  I'm not particularly familiar with similar Visual but LabVIEW is usually good enough to communicate with third-party software. You said you tried to make calls through ActiveX (which was also my first try) and that doesn't seem to work. Below, I have included a link to an article that should be helpful when trying to interface with other software using LabVIEW.

• Agilent 8648C control with Labview

  I download the driver 8648A http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=533 and use it to control Agilent 8648 C. When I put initialize.vi to the application, the erroe 1223 meassage is shown and if I didn't put the initialize.vi in the program, it works. I think it's because the intitialize.vi's 8648, how do I change to make work for 8648 C. thank you

  Change of the cable to the string constant model function of correspondence for 8648 just or the test for A 8648 or 8648 C. Also, you realize that you don't have to do the query ID, you?

• Solenoid control with LabVIEW

  
  
  

• PID control with big delay in the process variable

  Hello

  My goal is to control the temperature via a valve and heat exchanger. I proceeded variable (temperature) measured from a hose. This temperature should be raised a few degrees with a heat exchanger. So basically I need to order a valve that allows the water to flow through the heat exchanger to raise the temperature to the desired level.

  My original plan was to use a base PID regulation to operate the dispenser. However, it is about 0.5 to 1 minute of delay time in the temperature probe after I opened the valve, which increases the temperature. This leads to a situation where the PID regulation valve fully open during this period (trying to get the temperature rise). Then once the temperature begins to rise it fires quite quickly. PID begins turning the tap off almost immediately, but because of the time delay in the sensor, the temperature exceeds seriously. This led to severe oscillation and at worst unstable processes. I tried to adjust the PID control to "predict" the timer to close the valve in advance to minimize the excess, but failed.

  I would appreciate if anyone has any ideas how to make this type of control with Labview PID functions. I also wonder if there is a better type of control procedure for this scenario as a PID control?

  -Lars

  This is a very common situation in the heating control, and generally PID can be adjusted to make it work. How do you do the tuning? If you do it by trial and errors, you have little chance to succeed. For a slow process with time delay, I like to use the method Cohen Coons, or similar open Ziegler-Nichols-loop method. The idea is that you temporarily remove or disable the PID. Set the valve in a fixed position and wait for the temperature to stabilize. Then, change the setting of the valve and record temperature at regular intervals data until the temperature is stable again to a new value. Use these data to get the initial values of PID using the equations provided by the tuning method you choose.

• With LabVIEW how to control an instrument with a RS232 output, using a USB RS232 converter cable.

  With LabVIEW how to control an instrument with a RS232 output, using a USB RS232 converter cable, since I do not have rs232 ports. I have two instruments I want for the control in this way. One is a guarantee of strength Imada SPAS with RS232 output. The other is a micrometer Panasonic HL-G103-S-J laser sensor which is RS422. I have done significant programming LabVIEW using GPIB, but I have no experience with devices such as these. No matter what tutorial or examples would be greatly appreciated.

  Thank you.

  When you plug the USB-RS-232 converter, it installs a driver under Windows which makes it look like any other RS-232 port.  You may need to install the driver of everything that came on the CD with the converter.  It will get a Com as Com5 port number according to what is the next available number.

• Robotics/control system with LabView real-time + OR DAQ

  Hello

  I am building this real time application in which you can try control methods for a particular system (construction of the algorithm of control in LabView on Windows) and then with a DAQ board (I have the E-Series SCB-68) communicate with the hardware (actuators).

  Is this DAQ card enough or should I try with any other advice? For the application considered, it is important that the price of the freq is at least 1 kHz.

  Thanks in advance

  The 6220's card perfectly fine for your current application.  It is true that windows is not deterministic and cannot compete with the hardware/software in real time, but your DAQ will be responsible for the management of timing and synchronization you will be fine.  If the advance until you need a very quick response in real time of your application, you can always buy a RT LV system.

• Possible GPIB communication through interactive control of Visa, not with Labview

  Hello

  I have a communication problem with Labview with GPIB instruments (with functions of visa).

  I get:

  "Error 1073807298 occurred at the VISA opening

  Possible reasons:

  "VISA: (Hex 0xBFFF003E) failed to perform operation due to i/o error."

  However, it works with an interactive control visa and this is where I am confused!

  Here is my setup:

  -Labview 2011 assessment

  -VISA 5.1.2

  KUSB - 488B with the associated drivers (adapter USB to GPIB of Keithley)

  Because I can speak with my instruments in visaic, I guess the installation of drivers for the Keithley interface is ok.

  Trace IO NOR I see beeing of commands passed through Labview to VISA so that they "see" between them.

  I found a thread where someone had the same problem and its solution was downgrade to Labview 8.5.1, which is not possible for me.

  http://forums.NI.com/T5/instrument-control-GPIB-serial/Keithley-2700-driver-problems/TD-p/1474212/PA...

  You have an idea to solve this problem?

  Kind regards

  Baptist

  Here's a follow-up on this issue.

  I tried with Labview 32-bit on main machine: it works.

  The pleasure is that I have to use Labview 64-bit.

  So the ultimate solution is now to run a client and a server of visa on the machine: Labview 32 bit can directly access my resources GPIB, Labview 64-bit must go through the closure of the network.
