I can perform a tag read, but not a writing of the tag

Hello

I'm relatively new to Labview.  I recently bought the EthernetIP for Labview 2014 library and try to establish communication with a Contrologix 5561 with an ENBT ethernet module back.  I did so far, some programs of barebones namely, a few blocks from Tag Read to read to bool, ints, deformations and real numbers.  Which works very well.  I have change the label on the side of plc, and the change reflects my LabVIEW VI.  I am now on the written tag part and will not have the same success.  My current VI consists simply of an EthernetIP write tag (INT), the IP (and bottom position of basket and slot) to the path network, an existing tag name and a constant (tried control earlier) in the data port.  It is almost identical to my readings of tag configuration, except that I have an input rather than output.

I know that I do nothing to establish a correct connection, but since tag reading working well enough, I have not focused on that.  Maybe I am missing here.

Anyone has any advice on what I can do to fix this problem?

Thank you

Nick

Hi Nick,

Welcome to the forums and congratulations to be a new user of LabVIEW!

I checked the attached vi. And I found the data you have provided to the Write.vi of the tag must be rectified. Data table 1 d of U16. you have specified that the index of the element that is 12 and you don't have any value of it. You can see that the value field is always gray, which means, you have not provided any value that you want to write in PLC. So I hope that you won't see any value next PLC.

It is also recommended that such read/write function in a loop to happen without interruption to a read or write rate.

In fact all National Instruments products come with example a need screws to help customers get started with their applications. "If you open LabVIEW, you can enter in the Help" find examples.  This will open the Finder of example of OR.  Here, you will be able to find examples on many best practices with NI LabVIEW and our material. "" "In NEITHER example Finder, open material input and output" NOR-Industrial Communications "EtherNet/IP" EtherNetIP Adapter.lvproj. You can refer to write and read Tag.vi for the service you need.

I hope this helps you!

  • Equium L20-264: CD/DVD player can read but not burn discs

    Hi all

    I need help. My laptop cd/dvd driver does not recognize the discs inside. It only happens when I try to burn a disc. She can read but not burn the discs. What could be the solution? I tried different brands, the last time it was Maxell. The manual suggests Mitsubishi discs, but I'm not sure that it only works with the Mitsubishi discs. It can read any kind of disc.

    So I'm in trouble, please help.

    Hello

    In the manual, you will find a list of media recommended because this media has been tested and were working properly.
    However, I use TDK CDs and DVDs and it works as well.
    Juan suggested in another ad that sometimes 3rd applications or DVD copy locks are responsible for some driver problems:
    http://forums.computers.Toshiba-Europe.com/forums/thread.jspa?threadID=12497

    What I mean is that it is not easy to give a generally the solution of these problems.
    You should try different media, burning software and if it doesn t work so it s is a malfunction of the equipment. In this case, you will need to replace the drive.

  • MKS 925 transducer - able to read but not write.

    I have labview code running that communicates with the two transducers MKS 925 regularly pulling their transcripts once per second.  He has stopped communicating recently and I was at a loss to identify the breakdown in communication.

    I opened NOR-MAX to test the separately from the program's communication and checked it is a failure of communication there as well.  I plugged in a PRD900-12 and confirmed the transducers can communicate with other devices, but not with the computer I'm on.

    With the help of the PRD900 I tried to send a signal to test for labview and with success has received it, but still have the error message: "error reading VISA operation: (Hex 0xBFFF0015) timeout expired before the operation is complete."

    I confirmed that I use the right address for the PRD controller and transducers.  I also checked and made sure that the right com ports.  The "write" command I send must change the address on the transducer or the controllers and it doesn't.  I am able to change the address from other devices via a serial line, but not through communication NIMAX and not through my labview code.

    Because writing orders do not work, the transducers/controller never taken trouble to answer and I get timeouts on my reading.  I am new to both labview and NEITHER so I don't know if there is an obvious mistake, I do and would love your feedback.

    I have searched several times for problems to be able to read but not able to write and everyone seems to have the opposite problem, but in advance I apologize if this is a repeat problem answered elsewhere.  I'll be happy to provide more information if I left something that is necessary to solve the problem.

  • Can print from other applications but not PS

    I'm trying to print from my Macbook Pro 2011 to a brother 2240 laser printer. I can print from other applications, but not of Socialist Party (CC 2014). In the preferences system, the printer shows as online, but in the PS print dialog box, when I click on the printer icon bit to the right of the selected printer, something of utility Brother appears and displays offlilne. But if I go to TextEdit I can print to the printer. Any ideas?

  • Smart card reader does not correctly connect once the virtual machine is restored from sleep using the vmrum controls

    Smart card reader does not correctly connect once the virtual machine is restored from sleep using the vmrum controls

    Scenario is,

    1. smart card reader is connected to the VM with card inserted in

    2 initiate a prompt suspension of the VM toolbar

    3. now to resume the virtual machine by using vmrun command into the host machine

    WS t vmrun start xxx.vmx

    Now, the recovery of VM but the smart card reader that was previously connected does not work properly in VM that is to say, sometimes after CV chip card reader driver is uninstalling and a few other times, chip connected to the drive is not available on a virtual computer

    My requirement is after power, smart card reader can stay connected to the virtual computer with the already installed driver and the smart card.

    Kindly help with this problem.

    Host operating system: Victoire 2012 R2

    The VM OS: win 10 x 64

    Thank you!!

    Dear all,

    I had a work around for this problem. By adding "usb.autoConnect.device0 ="0xVID:0xPID"" this statement to the VMX file, solves this problem, that is, whenever the VM is wake-up by clicking on the link CV or using vmrun commands, it connects the unit in question automatically and it is charging correctly with his driver. Obtaining smart card detected after sleep\hibernate with no problems.

    VID & PID is respective ID of the device that can be seen in the properties of the Device Manager "Device Instance path".
