  How to create connectio between labview and welder ultrasound for implicit Messaging.

  Hi Emily,.

  I'm afraid that you can't create implicit I/O communication between labview and ultrasonic welder.

  This is because the driver of the National Instrument is not a scanner, but an adapter (slave) and therefore the position to solder ultrasonic.

  This means that we cannot launch an instance of IO.  This does not mean the National Instrument driver cannot communicate via e-mail, just that it cannot start this communication.

  I know explicit message is not as fast as implicit messaging, but if you are not running transfer limits you can always use explicit messaging.

  Explicit messaging speed can reach up to 100 Hz.

• Connect LabVIEW to Schneider Electric M258 Logic Controller (TM258LF42DT4L) error - 1967353901

  I was wondering if someone has never connected this particular PLC before LabVIEW. I'm trying to control instruments connected to this API. These instruments aren't NEITHER, therefore they that I could not directly connected to the device via USB, GPIB or VISA. Whenever I have try t connect following this tutorial OR (http://www.ni.com/tutorial/13911/en/), I have an error message to my shared variable.

  The possible reasons: LabVIEW DSC: (Hex 0X8ABC8FD3) the I/O modbus server cannot connect to the Modbus Ethernet slave device. Make sure that the slave Modbus Ethernet device working properly and that the connection between the master devices and Modbus slave is configured correctly.

  Any help on this approach or suggestion for others would be greatly appreciated.

  NOTE: This controller communicates with the CPU I use via a RS485 / RS232 serial port.

  SAM

  Right, but if the unit will not pass a review of the communication of its native software so it is not really a chance that LabVIEW will be able to communicate with him. I could contact Schneider and see if they can help you make contact with their software, we can worry about communicate using LabVIEW.

• Exit via LabVIEW tension control

  Hello

  I'm trying to control an AC output voltage of 0 ~ 250V using LabVIEW, but I could not find any device that makes this kind of operation and can communicate with LabVIEW. All available NEITHER Renault only operate in low-voltage (-10/10V) for the generation of signals. Nobody knows everything power or the method could make this function?

  Thank you!

  Really, you have not used your Google-fu if you do not find a programmable power of ca. Keysight and California Instruments are just two of several suppliers.

• LabVIEW and Spider8, school project

  Heey everyone.

  I have a little problem and I hope that one of you could help me with this problem.

  I try to get the data of a Spider8 with a laptop equipped with LabVIEW, I do this by using a USB cable to series, instead of a parallel cable.

  I have defined this USB to serial as a COM port cable:

  [URL =http://img59.imageshack.us/i/devicemanager.png/] [IMG] http://img59.imageshack.us/img59/4613/devicemanager.PNG [LINE] [URL]

  Then, I installed the spider8 software. After I tested the communication between the laptop and the spider8 using an altitude sensor, this sensor has an output of 0V to 10V. Communication was perfect between the Spider8 and portable, as you can see below, (I put the probe in channel 0)

  [URL =http://img14.imageshack.us/i/spider8setup.png/] [IMG] http://img14.imageshack.us/img14/6200/spider8setup.PNG [LINE] [URL]

  Now, I copied the Spider32.dll file and copied in the "WINDOWS\system" and "WINDOWS\system32" directory so that labview can see these .dll files.

  [URL =http://img25.imageshack.us/i/spiderdll.png/] [IMG] http://img25.imageshack.us/img25/7715/spiderdll.PNG [LINE] [URL]

  [URL =http://img17.imageshack.us/i/spiderdll2.png/] [IMG] http://img17.imageshack.us/img17/7489/spiderdll2.PNG [LINE] [URL]

  Now, I used the example of www.hbm.com .vi for attempting to communicate between LabVIEW 8.2 and Spider8. But WHENEVER I try to run this example, I get the following error:

  [URL =http://img134.imageshack.us/i/fehler1.png/] [IMG] http://img134.imageshack.us/img134/198/fehler1.PNG [LINE] [URL]

  The vi called S8_InitAll is at the very beginning of the program, take a look at the example of HBM blockdiagram:

  [URL =http://img269.imageshack.us/i/blokdiagram1.png/] [IMG] http://img269.imageshack.us/img269/2316/blokdiagram1.PNG [LINE] [URL]

  When the case structure is false, this vi gives the error:

  [URL =http://img143.imageshack.us/i/blokdiagram2.png/] [IMG] http://img143.imageshack.us/img143/6060/blokdiagram2.PNG [LINE] [URL]

  It's the S8_InitAll vi: (frontpanel, blockdiagram and "call library" function)

  [URL =http://img12.imageshack.us/i/s8initall.png/] [IMG] http://img12.imageshack.us/img12/8415/s8initall.PNG [LINE] [URL]

  I seriously have no idea how to solve this problem, whenever I run the example program, I get the same error. I did something wrong with the DLLs from the East - it something else? Please help, thanks!

  
  

• How to control and monitor labview omron plc

  Hello

  I am able to do to communicate with labview 2009 using plc NOR a CPB and Module DSC server via ethernet, but I don ' t now to control and monitor data Boolean plc from labview.

  the machine I use is CPU11 CJ1M Omron CJ1W-ETN21 with. I'm still very new to labview and I hope someone can help me with this and give me some advice on how to proceed. It should also be noted that I can't change the status of the labels directly from NI OPC server itself.

  Here is the simple circuit that I would use as a starting point for the control and monitoring of the data of the PLC from labview:

  

  Thanks in advance for the help.

  You can read from the entry, impossible to write.

  For output, you can read or write.

  However, if you have a scale controlling this line out.

  There will be a conflict.

• Problem of Windows vs Mac OS with socket read/write and LabView

  Hello
  
  I inherited, multithreaded code, with a singleton that communicates with LabView via few ports/sockets. I don't know (but don't think) mention it in this case multithreading issues, but in case you think there could be a problem. All communications to the LabView through LabView class (instance) singleton.
  
  When we run the code on the same box of MS Windows XP as the LabView so, it works properly; This means that LabView receives orders and the java receives the results. When we run it on a Windows XP box in another room with another subnet it works fine as well. When we run a Mac OS in the same room/network reader.ready () is not true in the time-out period. (see the line of reader.ready () in the original code).
  
  Does anyone know why it would work for Windows but not Mac OS?
  
  A current "guess" what is bad on my part, is that code below (taken out of context, otherwise the position would be really long) needs of some rethinking. Any help/comments/advice on how it is encoded is greatly appreciated.
  
  Here are the existing code.

      }
  
      public synchronized float potlistener() {
  
          String message = null;
          t0 = System.currentTimeMillis();
          t1 = System.currentTimeMillis();
          boolean donereading = false;
          while ((t1 - t0) < (waittime) & donereading != true) {
              t1 = System.currentTimeMillis();
              try {
  
                  while (reader.ready()) {
                      message = reader.readLine();
                      logwriter("LabV: [received] " + message);

              }
          } // close timeout while loop
  
          return potvalue;
      }

  In particular, I have readLine() in a loop where I catch the exception if it is not read and just keep trying? What is the "best way" to do?
  
  Here's what I thought, something like:

          while ( ((t1 - t0) < waittime) && !donereading ) {
              t1 = System.currentTimeMillis();
              try {
                  message = reader.readLine();
                  logwriter("LabV: [received] " + message);
                  if (message.contains(".")) {
                      potvalue = Float.parseFloat(message);
                      donereading = true;
                  }
              } catch (Exception ex) {
                  System.err.println("Exeption in potlistener() "+ex.getLocalizedMessage());
              }
          } // close timeout while loop

  (a) No, but I would look into the configuration of the network itself rather than the Java code.

  (b) the correct way to enforce a timeout of read is through Socket.setSoTimeout ().

• Analog value read with DSC Module Modbus

  Hi, I have a Delta PLC with an AD converter module. I use the four analog channels and in one of them, I have a thermocouple which displays temperature data on a microprocessor thermocouple meter. However, I want to display the data in Labview. The controller communicates with labview through the DSC Module of labview with success, but I am not able to read the data. Looking forward to your help.

  Found the solution. addressing to the modbus master was different for this model of plc, so I looked up the address for delta plc Modbus and the analog read list has been a success on labview.

• Screenshot on tps2000 series oscilloscopes

  Hello

  I've been trying to solve this problem for the last days. I have a Tektronixs TPS2024B oscilliscope that uses RS232 to communicate with Labview 8.0 and 2012 (both have the same result). The goal is to get a screenshot using commands on PAPER of Tek. I can reicive a bitmap image, but it's only part of the bitmap and the rest is black. See photo and code below.

  You can see the oscilliscope take the paper and there is of course the bytes written to the bitmap of the read buffer. I tried to place delays everywhere to see if that was the problem but nothing helped.

  Someone at - it suggestions? Thank you.

  

  

  Instead of reading 1 million bytes, read a few hundred at a time in a tight loop.

• Naming of the third-party devices

  Hello

  I'm quite familiar with the basics of coding Labvew and the handling of the device, but until recently, I've always used decives of National Instruments. I recently installed a computer (USB-202) of the measurement data acquisition and their Labview drivers installed successfully. When I run a question, is that I run 5 different hardware, and I would give them every meaningful IDs, instead of Dev0, Dev1, etc.. I know it's simple enough using MAX, but the Measurment devices are not picked up by Max I tried to rename the devices by using the software provided by Measurement Computing, but it does not seem to communicate to Labview. Is it possible to appoint the devices in a way that recognizes Labview?

  Kind regards

  A quick update. I implimented the above code and found that it reads the device number (for example Dev0), but does not provide a way of naming the unit of something meaningful. A subsequent appeal found that such an operation was not possible,

• Error 66: TCP Read

  Hi all

  I need to communicate with a machine to send a unique information. This unique information is to provide different sensors that communicate with Labview. My problem is when I start my VI, he stopped 30 seconds with the error code 66. You can see attached a screenshot of the error and my VI. This error that when I use a while loop, if I use the term continually touch the error does not appear.

  As a beginner I don't really know the origin of this error. I only know that it can be linked to the respons of time between my computer and the controller.

  Thanks in advance for your help

  Concerning

  Baptist

  The model of the automaton is a pro-deal LM 4301

  Looks like something is to be constantly opened and closed.  You really shouldn't do.  You must initialize once before the loop and close once after the loop.

  Specifically, this error indicates that the instrument has closed its connection.  You make something for him say to unplug?

• NI-VISA takes a unique I.D. number for each USB device?

  Hi all

  I'm relatively new to LabVIEW and VISA Toolbox.

  When you communicate with LabVIEW and a USB via VISA, VISA shoots a D.I. unique number for the USB device for each connection established?

  I have reference: http://www.ni.com/white-paper/4713/en

  Kind regards

  Bryan

  Bryan,

  I don't understand what you're saying, so let me rephrase my answer and see that if this may help you - IF your device properly implements the USB standard and has a serial number, VISA uses this serial number.  If your device does not implement the USB standard correctly or if it does not have a serial number, VISA will do for you.

  If your device has a serial number, the VISA can be used to communicate with it.  There are routines that detect and identify VISA devices connected to your PC.

• PCAN USB with NI-CAN adapter

  Hello

  I intend to communicate that LabVIEW with a controller to motor through the CAN network by using an adapter USB-PCAN system Peak. I wanted to know if NI-CAN be able to send and receive commands through devices that are not National Instrument (in this case, it will be the USB PCAN-adapter of the system Peak). Can anyone who knows something about this topic help out me please?

  We used the PCAN USB with the LabVIEW RIDGE driver provide. I don't think you can use NI-CAN or NOR-XNET to talk directly to the network using the PCAN USB CAN but we use the conversion functions of NI-XNET to convert between the CAN messages and signal/data value and vice versa, and then use the driver PCAN LabVIEW for read/write messages.

• PEUT

  I have three loops that operate independently control the separate devices. I want to their poll continuously for about five seconds at a time. The reason for each device to mark, is I want to communicate to Labview, through a device CAN (8473). Y at - it an easy way to accomplish this question / multiplexing by distribution of task and maintain each independence loops?

  Thank you.

  Here is a sketch of what I mean.  I don't know if there is an example of the expedition which shows this exactly, but certainly there are examples on the use of queues for communication between the loops.
