How to use labjack U12 to control solenoid directional valve with Labview in hydraulic system

Hi,
I need to control a solenoid operated direactional valve in hydraulic system with Labjack U12. I am using three relays but need some help on the vi. like which instrument drive I need to use etc....
The coil voltage for the solenoid valve is : AC120V, 60Hz; AC110V, 50Hz
My goal is to control this solenoid valve open/close at certin time, am using Labview 2011. Any advise would be helpful.
Thank you!

Have you got the relays working yet. Do some initial testing with LJlogger to make sure hardware is controlling the relays as expected. If you need further help with this step, provide a link to electrical details for the relays and describe how you have the relays connected to the U12.
As for your programming in LabVIEW, I suspect you are using digital I/O, so the simplest thing to do is call EDigitalOut() to set a particular line to output-high or output-low, or if you need to set a line to input (for open-collector style control) use a call to EDigitalIn(). Perhaps look at "e function example.vi" to get started, and for general information about using the LabJack U12 with LabVIEW see topic #84 from the LabJack forums.

How to use preprocessor directives (#define) in C++ header file with LabVIEW 8.2

I have a C++ header file that contains around 2000 preprocessor directives:
#define MEM_1   0xC
#define MEM_2   0xD
#define MEM_3   0x18
I want to be able to "access" these memory offsets by identifier name (MEM_1) in my LabVIEW program like I would in a C++ program. I do not want the overhead of parsing through the header file and storing all the offsets into an array or similar structure.
I've written a simple Win32 console program to return the memory offset given the identifier (see code below), and created a DLL to use with my LabVIEW program. In the console program, you notice that I can call a function and pass in the identifer name, and get the offset back correctly:
getOffset(MEM_1);
In LabVIEW, I was hoping to be able to pass in the identifier (MEM_1) but was unsure what datatype to use. In my C++ code, I defined the parameter as an int. But in LabVIEW, I can't enter in MEM_1 as an int.   Can someone advise on how to do this? Or if there is an alternate way to use #define's from external code inside LabVIEW?
#include "stdafx.h"
#include "scrmem.h"
#include "stdio.h"
void getOffset (int var);
int _tmain(int argc, _TCHAR* argv[])
getOffset(MEM_1);
canf("%d");
return 0;
void getOffset (int var)
printf("The address of MEM_1 is %x", var);

Hi,
Where do you think I should use the string?
The way that getOffset is currently defined in the DLL, I have to connect an integer input into the LabVIEW function. This prevents me from entering in: MEM_1 as the input to the LabVIEW function.
Are you suggesting that I change getOffset to receive a String parameter ("MEM_1")? Does that mean I need to do a string compare (line by line) through the header file to get the offset? It seems like doing this search through the header file would degrade performance, but if that's the only work around, then I'll do it.
Please advise.
Well, what you want to do is indeed entering a string and getting back the assigned integer. That is what the C preprocessor is doing too although there it is done only once at the preprocessor stage of course and not at runtime anymore. But LabVIEW is not a C preprocessor.
What you did so far seems to be to define getOffset() that accepts an enum that needs to be created from the C source code to then return the assigned constant. That's of course not very helpful.
And writing a VI that could parse the C header file and create a name/constant array is really a lot easier than doing the same in C. You don't even need to parse the file each time again, but can instead cache them in an uninitialized shift register (LV2 style global).
Even more easy would be to create from that data a ring control using property nodes and save it as custom control and voila you have the most direct lookup you can get in LabVIEW and it works just as comfortable as using the define in C code. It would mean that you need to seperate your header file possibly into several different files to only get related constants into the same ring control, but that is easily done.

Most of us in this forum are users who volunteer on technical issues, and not Adobe employees although they do drop in from time to time. As users we simply have no control over activation and that's why you are not getting responses.
If you havn't done so,you might try the Muse forums and see if you can get a staff member to look into it. Have your case numbers and phone transcripts handy.
Last option is to keep calling customer service until you get someone who will help or ask for a supervisor.
Hope this get resolved,

TM does not work like that.
If you want files to use later.. do not use TM.
Or do not use TM to the same location. Plug a USB drive into the computer and use that as the target for the permanent backup.

How come you can not use more than 126GB of a 1.5TB diskdrive with LabVIEW Real Time?

How come you can not use more than 126GB of a 1.5TB diskdrive with LabVIEW Real Time?
This is only 8.3% of the available disk drive space!
http://digital.ni.com/public.nsf/allkb/E7E2F5657B6026358625750B007201A6?OpenDocument
National Instrument's solution is either reformat you drive to less than 126GB or replace the drive with one less than that size.
Please NI, tell me you are going to fix your LabVIEW Real Time soon, and that we won't have to wait for LabVIEW RT 9.2.1 in 2011 for this one to be fixed.
http://upload.wikimedia.org/wikipedia/commons/9/90/Hard_drive_capacity_over_time.svg
Drives as large as 126GB or more have been around since about mid 2002. That's about 7 Years now and LabVIEW Real Time STILL can't use drives larger that 126GB! Please NI. Do something.
We deserve fixes to the old versions of LabVIEW RT. How about updates to LabVIEW RT. Such as 7.0.2, 7.1.2, 7.6.2, 8.0.2, 8.2.2, 8.6.2.
We don't need new features or versions of LabVIEW RT such as 9.0 until we have some of bugs fixed in the existing versions.

The RealTime OS is an NI Product that is purchased from NI.
NI may or may not outsource design, developement, or manufacturing of the products that it sells under its own Company name.
For this reason I would be concerned if I were a PXI Embedded Controller designer/developer in the United States.
Yes, 126GB is some space. I see that there are now 2TB drives available. 126GB would be 6.3% of a new 2TB drive. Should we all be happy with being able to use 6.3% of the available drive space. Moore's Law seams to be alive and well. Drives larger than 126GB have been readily available for 5 or 6 Years. This should not be a surprise to NI. Why don't they do something about it.
Thanks for the trivia on Bill Gates. I must have missed that one since I don't try to keep up with Microsoft. I believe that he is a wonderful person and he and his family are doing wonders for the world in their "retirement". The world needs more like him.
What I do remember is Steve Jobs telling us that we would never need more that 128MB and that we would never to need to do anymore software development because everything was already in the "ToolBox".

I need to control a Ransco temperature chamber with LabVIEW

I need to
control a Ransco temperature chamber with LabVIEW. The temperature chamber requires four BCD digits
plus a – /+ bit and some control lines. I have a piece of hardware attached to my PC
called LabJack. LabJack has 16 digital
input/outputs, 8 analog inputs and 2 analog outputs. What I would like to do is control the
temperature chamber with LabVIEW using the LabJack as an interface. Has anyone in the group done this or something
close to it before? Also has anyone used
LabVIEW to control a LabJack for any purpose?
I would be interested in looking at what you did and what drivers and VIs you used.
Thanks,
Gary

Try reading this thread. It might not be terribly helpful to your application, but it might answer some questions. Also look at the Labjack site to look for the LabVIEW VIs that they have written.

The Call Library Function Node will allow you to call a DLL. To do so, you need the documentation on the DLL. This documentation would list the functions as well as the arguments for those functions (i.e., inputs and outputs). There does not seem to be any documentation in what you uploaded. Actually, I have no idea what you uploaded, aside from the fact that one of those files was the actual DLL.

How to use HTML in JavaFX controls?

Does JavaFX support using HTML in JavaFX controls' text? For example, in Swing components:
button = new JButton("<html><center>Enable "
+ "middle button</html>");
If no, could we find a workaround?

Embedding a WebView in a Labeled for HTML Rendering
A WebView is a node which displays HTML.
Most controls implement Labeled, or have elements that are Labeled.
A Labeled has a setGraphic(node) method which allows you to set the graphic attached to the labeled to any given node (including a WebView).
For instance:
WebView webview = new WebView();
webview.getEngine().loadContent("<html><center>Enable middle button</html>");
webview.setPrefSize(150, 50);
Button buttonWithHTML = new Button("", webview);
should create a button with html in it (I didn't actually try running the above example).
Apart from the relatively slow startup time on first use and the overhead (which I can't quantify) of using WebView in this way, there are a couple of jira requests outstanding which make it a little bit of a nuisance.
RT-25004 Allow for transparent backgrounds in WebView
RT-25005 Automatic preferred sizing for WebView
You can vote for the above jira requests or comment on them if such functionality is important to you.
TextFlow/FXML/CSS Alternative
Rather than using html in the Labeled, support for the TextFlow control was introduced in Java 8, so that could be used instead.
TextFlow also works well with FXML and css if you prefer to have the stuff in the TextFlow managed via markup and a declarative styling language.
Open Feature Request
There is an open feature request RT-2160 HTML support for text which is currently scheduled for implementation in the initial Java 8 release. I think the likelihood of it actually being included there is zero percent, though it may be considered for a future release. You can vote for the issue or add comments to it, or provide an implementation if you are so inclined.
Implementation Considerations
A possible implementation would be something which parses the HTML then constructs a TextFlow the parsed HTML according to processing rules which are laid out in laborious mind-numbing detail in the HTML5 spec.
You could use a relaxed HTML parser such as the validator.nu parser (though there may be others which would be a better fit).
A simple implementation would just be to use the parser in the jdk which is used for the swing controls, but that is hopelessly outdated.
Perhaps, even simpler would to only accept strict html input and just use SAX to parse it out, though things like validator.nu are too difficult to work with.
Then, for the limited number of parsed tags that you want to support (and you really don't want to support all of HTML5 for something like this - otherwise you would just use WebView), create your TextFlow from the DOM model that your parser has created.
I wouldn't even both trying to handle most of the stuff in your html string in your implementation, stuff to do with styling, fonts, colors, etc. Those things were never any good in html anyway, and css is better for handling them, so just support stuff commonly used in usual modern day html (take a look at bootstrap html source as an example to see what that might be - if bootstrap doesn't use it, I don't think you should support it). The stuff you will be supporting are things around document structure like lists, headings, etc. div blocks and span nodes - so only implement that important stuff and delegate everything else to css where it belongs.
Also make sure your implementation fits in with FXML so that you can easily embed your html subset in an FXML doc.
