What pins to use to receive the data from the PDS ELITE RS485 with the PXI-8431/2?

Hello!

I use the PXI-8431/2 to read data from the flow meter PDS ELITE (Modbus RTU). Receiving data, the RS485 protocol request to terminals 4 and 5, but this configuration does not seem to work. When I connect the RS-485 converter USB of Microflex I get the data correctly, so somehow between the PIN lay and PXI this problem there.

Can someone help me?

See you soon,.

Steven

Hello Steven,

I think that what was Hossein trying to send you is the following:

How to connect and configure a device with RS-485 2-wire

Can you also tell me a little more what you use to read the data? What environment. You have 2-wire or 4-wire Modbus RTU?

Kind regards

    Most likely, what you found, is that the iTunes version is the latest available for your operating system.

    The latest version of iTunes is 12.4.3.  This version requires at least OS X 10.8.5 or later version, or Windows 7 or later version.

    If your iTunes version is earlier than 12.4.3, it will probably not recognize your 6s performance iPhone iOS 9.

    If you do not have the required operating system, get first.  Then download from iTunes

  • How can I use notifications to send data from different sources for the same chart?

    Hello

    I use the model of 'Continuous measurement and logging' project comes with LV 2013.

    It is extremenly helpful in understanding the messaging between the acquisition, graphic and loops of newspaper. (Thank you NEITHER!)

    I ran into a snag though.

    I want to change so that my graphic loop receives notifications of data from two sources of acquisition by the declarant.

    I have trouble getting the data from the two sources to display on one graph.

    I've isolated the problem in the attached vi.

    Here's what happens:

    1. I create 2 parallel loops data and send the data to a third parallel loop with the notifiers.

    2. the third loop receives data from one of the loops because one of the authors of just receiving notifications is to expire instead of receive data.

    Can anyone suggest how can I fix?

    Thank you.

    -Matt

    Here's my modification of your VI. I put notes on the block diagram to explain the changes. He uses a queue for data transfer to avoid data loss. It uses a notifier to stop loops. All local variables and value property nodes have been eliminated.

    The way loops are arrested probably let some data in the queue. No more of one or two iterations of each of the loops of data acquisition. If you need ensure that all data has been displayed (or recorded in a real application), then you must stop acquiring loop first and read the queue until you know it's empty and both other loops stopped. Then stop the render loop and release the queue and the notifier.

  • Should what product I use to replace the measure?

    Hello

    I have a client that was used to communicate with GPIB and, possibly, hardware DAQ measurement in Excel. He knows failover with able and interested in moving away from another product. What products would provide the simplest transition? I'm interested in any comments/ideas that you might have.

    A large part of what is today can be done fairly easily to in Excel using the macro editor, even if it does not require you to write code to do rather than use the interactivity that measure provides.  Measure includes a conversion utility that allows to convert a measurement task to VBA Excel based on some of the ActiveX of Measurement Studio controls.  You could also use VBA Excel (or new versions of Excel, .NET) directly with our language DAQ and GPIB interfaces.  Yet once, this would require an amount of programming in Excel.  We also have examples that show how to acquire data with LabVIEW and then send these data in a worksheet.

  • Receive octal data from InputStream - hexadecimal instead

    Hello

    I'm creating a Java SE 7 desktop application that should copy what makes an already implemented a PHP. To make sure that everything works as expected in the application Java, I've got this method:

    + public static void printValues (String string) {+
    System.out.println ("\nPRINTVALUES :");
    System.out.println ("length:"String.Length;) +
    for (int i = 0; i < string.length ();+) {+
    System.out.print ("x" ((int) string.charAt (i))); +.
    +}+
    System.out.Print("\n");
    System.Exit (-1);
    +}+

    which I use for debugging purposes. I have a similar method in PHP that does exactly the same thing, so I can use it as well for the outputs to compare and decide if all went well until methods are called. This method has been perfect since I started: I get the octal bytes in Java and PHP, and I can compare them. But there is a moment in the application where it sends data to a server and has in the process she responded. Using this method, I already checked that data sent in Java is exactly equal to one sent in PHP, but they may not receive the same response, and I can't even use the method above to make a comparison, because the Java application is printing the values hexadecimal ones rather octal. This is the method that I use to get the answer:

    private String readData() {}
    Buff of String = "", data;
    ubyte bytes [] = new byte [1024];
    InputStream input = null;

    try {}
    entry = this.socketChannel.socket () .getInputStream ();
    } catch (IOException ex) {}
    Exception handling unnecessary code
    }

    int howManyRead = - 1;
    try {}
    howManyRead = input.read (bytes);
    System.out.println (howManyRead);
    }
    } catch (IOException ex) {}
    Exception handling unnecessary code
    }

    Byte [] newBytes = new ubyte [howManyRead];
    System.arraycopy (bytes, 0, newBytes, 0, howManyRead);

    String ret = new String (newBytes));
    org. Main.printValues (ret);

    return ret; Currently unreachable stated, the output for the comparison is performed in the sentence above, which includes a call to System.exit(-1).

    Could someone help me please to retrieve data in the form of bytes actually octal if I get the data in the same format as in PHP (octal)?

    Thanks in advance.

    You receive a stream of bytes and you want to dispay their values. You expect to show that 0, 1, etc. up to 255. These bytes are not text. The conversion to string is useless and dangereous. Work with byte [] all the way. Converion of bytes to a string can lead to random, values that are represented by characters whose values exceed 255. This can also cause a loss of data if a received "character" is not mapped to a real character into your encoding platform.

  • Can someone tell me what software to use to print and scan from my MacBook pro

    I have Mac OSX Mountain Lion and I am trying to print and scan my 5510 Photosmartt wireless. I tried to use the full suite of HP and Apple software for the printer. The HP software does not find my printer on my network only when it is connected through USB. I used the option "wireless via USB" when I installed the software, but the process never went through a process of Wi - Fi as soon as I unplugged the USB cable it was impossible to find the printer. I also tried to add a printer manually using the host name of Bonjour that works but loses connectivity on occasions, but I am then unable to use the extras like the Apps that come with the HP software.

    I have an iPad which I can connect using HP Printer Control app but I was under the impression with the last update Apple what airprint totheirs device should work without the need for an application.

    I read all the advice of experts in many forums like this one and have tried everything, but I was unable to connect to my network without problem. I can scan, eprint printers EWS etc so I must be connected to the router and the Internet, so I really don't understand why I'm having these annoying problem. I know that I am not alone so concerned manufacturers should get it sorted and soon.

    I should also mention that I have a laptop win7 I have installed on the same netwrk and had printing and scanning works very quickly without any problem of connection at all.

    I'll be very happy to receive a solution from an expert very soon.

    Your suggestion is exactly how I installed the printer before but still had problems of connectivity with my MacBook. However I seem to have found the solution and it's, once the printer and MacBook on the same network I put then a static IP by allowing the software page to recommend a static address. Previously, I had chosen the static address manually by following the instructions provided.

    The difference now is that when I look at my page of router software the printer is more listed under DHCP DEVICE INFO, but I am still able to find the printers web page by inserting its ip address into Safari, as well as the EWS page

    This seems really healed my problems. Thanks for all your help.
