How to set the name of resource VISA as a constant?

I'm properly communicates with a device series using ModBus. The drop-down list on the front displays correctly COM3. I would like to remove from the drop-down list and set default COM3 on the block diagram. Can someone tell me how to do it please? Thank you very much

Hello

Right click on this drop-down list and select replace by, constant...

So you can see the name of constant of Visa on the block diagram and no need to pull down...

  • get the name of resource VISA

    I connect serial port COM3 to a digital multimeter, I can sure that COM3 is displayed in Device Manager. but I don't know if COM3 is in the name of resource VISA list. If COM3 is not in the list, I want to update resource VISA name.

    So my question is how to program can get the entire list of the name of resource VISA, so that the program can compare resource VISA with COM3 automatically name? How the program can update the name of resource VISA, if COM3 is not in the list?

    Thank you

    Control of resources VISA automatically displays the available visa resources. If it isn't then looks like there was an error in the installation of NI-VISA.

    An alternative is to use your own control, as suggested here: http://forums.ni.com/t5/LabVIEW/VISA-resource-name-control-want-to-refresh-list-of-COM-ports/td-p/13...

  • Can not find the name of resource VISA

    I am trying to run the example code, provided by the manufacturer with a 3a Keithley 2420 SourceMeter.  It is turned on and put in place for 488,1 protocol GPIB.  It is connected to my computer via a GPIB KUSB - 488A cable.  On the front panel of the example program, there is a menu drop down titled "VISA resource name."  The two options at my disposal are LPT1 and COM1, but I don't think one of this is the name of the resource on the right.  Does anyone know what the name of resource VISA should I use with the Keithley, or how I can find this? If it helps, I have provided the example program I use. Thanks in advance!

    As a general rule, only the material NOR will be recognized in MAX and you wouldn't get any VISA resource for Auditors not - NOR. If there is a VISA for the Keithley driver, you can try to install as secondary visa driver and enable Tulip MAX. Keithley support support is the best place to ask questions about the installation of their hardware to LabVIEW.

    The author information is located in the bar - descriptor.xml in the tab "General". But the information must be defined automatically. In addition, you must install the token debug on your device.

    If everything is configured properly there is only one problem that happened to me. I had several chips debugging Momentics. I had to remove all chips debugging and leave alone the I want to use. Perhaps, you have also several debugging chips installed in Momentics. This seems to be a bug in Momentics who can't handle several chips debugging.

  • How to use USB with the name of resource VISA?

    Hello

    I am new to LabVIEW and I'm working on a code that must acquire data from a measuring device. This unit has only a USB output, so I have to work with it. As far as know the block that is used to refer to an external port is VISA resource name. I installed a driver that recognizes the serial ports, and they appear in the list of VISA resource file to the front panel. So I thought that installing the DEVICE driver so that the USB ports would appear. I installed and nothing of USB ports. I don't know it's as simple as that, or work with USB ports is a little more difficult. I tried many things and nothing worked I am here.

    PS: I noticed that the version of the driver is 64-bit (my pc is 64-bit) and my LabVIEW version is 32-bit, what could be the problem?

    The device incidentally is Digital Analyzer WT500, Yokogawa.

    Thank you.

    Victor,

    the suggestion driver instruments is to make it easier by using the instrument.

    Normally, you need to install a player from the manufacturer (if it is not installed, the instrument appears as a USB in Device Manager) and the driver NI-VISA. But for some instruments, manufacturers have APIs that uses NI VISA to communicate with your equipment.

    In order to check whether your instrument appears correctly in Device Manager (as indicated by Yokogawa). If this is not the case, check whether Yokogawa has a suitable driver for this tool and install it.

    Is this clear?

  • How to pragmatically set the name of the user event?

    In LabVIEW 2010, I register a user event during execution by using the function of events Reg, but I want to put the name of the user event, according to the runtime. LV said "If wire you a cluster at the entrance to the data type of the user events , LabVIEW uses the type name of the cluster in the event user name." But I need set the name of the event based on the data that is generated during execution.

    How can I pragmatically set the name of a user with data from cluster event at run time?

    I can do this by changing the text of the label of the bunch before I use Reg events function?

    How will I know what name the user never received?

    Thank you.

    I found a viable solution. I can create a user with a name known event. The event that is sent with the event data will include a Source DN string that identifies the sender of the event. The event handler can then handle each event based on the name of the Source. This is equivalent to have several unique named events, is only right they all share a common event data format, which is OK in my case.

    It works very well.

    THANKS for all the suggestions.

  • How to set the properties of the individual parcels programmatically?

    Hi all

    I develop a XY chart that can have between one and six serial data.  How can I programttically set the properties of the series individually?  I can create a property node for things such as 'Name', but when I do it's only the name of the last data series is changed.  How can I set the value of 'Name' for different series?

    Thank you!

    You must set the field property Active before you set the Name property of draw.  The plot Active area must be on the index of the series you want to change.

  • How to set the value of a variable in a cluster in LabVIEW to c#?

    Hi guys, I'm working on a small c# program, which by using the interface provided by LabVIEW.  And I know that, with the help of lv. SetControlValue (name, value) can set a variable just on the front panel. But in my case, there are several groups on the front panel. Then it confused me how to set the variables in these groups. For example, there is a cluster named clusterA and a variable named a., I tried something like this:

    lv.SetControlValue("clusterA.valueA",1);
    

    but it totally inoperable. Everyone has some experience with this sort of thing? Thank you very much!!

    Hey guys, thanks a lot for all your response. I just found a simple way to solve this problem. For example, there is a cluster named "ClusterA", and there are only two witnesses, who are: an int value named "IntA" (default = 10 IntA value) and a string value named "StringA" (by default the StringA = 'abc'). In c#, if you call the method:

    var clusterA is vi (Array). GetControlValue ("ClusterA");

    you will get a table looks like: clusterA = {10, 'abc'}; So if you want to change IntA 123, you simply do:

    clusterA.SetValue (123, 0); 123 the value, 0 is the index of IntA in clusterA, after this clusterA table = {123, 'abc'}

    After that, simply to make the table in LabVIEW using:

    VI. SetControlValue ("ClusterA", clusterA);

    and now you see the LabVIEW, IntA is changed.
