How to interface with NI PCI-7344

Hi,
First off,i have to say im a newbie with labview so if tis is some stupid qns,my apologies.I nid to work out a program using LabView 8.0 to control a stepper motor thru NI PXI-7344 and the NI UMI-7764. The program is ready with the output as a 32-bit integer, However i am clueless to wad should i connect it to. can some1 kindly plz help me thanks

Nova,
Since you have a PXI-7344, it should have come with the NI-Motion
driver. Is that something that you have installed currently? If not,
you can find the latest version here.
To learn how to programmatically control a stepper motor, you might
want to start off by taking a look at some of the examples that come
with LabVIEW. To access them, open up LabVIEW, then go to Help >>
Find Examples...
Using the Browse by Task option, expand the Hardware Input and Output
folder, and then the Motion Control folder. Here you will find many
examples that you can examine to learn her to program your motion
control application.

TrueTime Card and how to interface with dll file!?

I am trying to interface with a PCI-SG 2U (IRIG) timing card (Used to made by TrueTime, now Symmetricom). Does anyone have a solution for this card in LV 2009?
If not, can anyone give advice on writing code to interface with .dll file? I am not sure how to pass through the "GENERIC_READ | GENERIC_WRITE" into the function to open the device. The function says to open it is:
TT_OpenDevice(boardID, GENERIC_READ | GENERIC_WRITE, &hDevice)
No clue on how to pass this in. Can anyone help?
Thanks -
Tom

Thanks Mike. I do have the .h file and the sdk information. I went through and used the Import>Shared Library Tool and was able to find all the header information that way. I guess that my problem/question is, the documentation says that it is a DWORD to pass as an input, but LabVIEW says it is a uint32. I guess the real question is, what the heck do I pass in to the dll function? Should it be the string "GENERIC_READ | GENERIC_WRITE" or something else?
Thanks -

How to interface with ROWID column in DB2?

I'm using DB2 version 7.1.
I have a column in a table called ROWID, and the Data Type is ROWID. However, I don't know how to interface with it in Java. For example, for CHAR and VARCHAR, I use the String class. For SMALLINT, I use int, etc. But what do I use for ROWID? It's not in the java.sql.Types list. The DB2 manual says it is stored as a VARCHAR(17), but I didn't just want to assume I could use String.
Any thoughts?

try getObject() and see what kind of object you get:
ResultSet rs = statement.executeQuery("...");
while(rs.next()) {
Object o = rs.getObject(1); // the rowid column
System.out.println(o + " class: " + o.getClass().getName());
}

Windows 2000 upgrade from win98--will i have problems with my pci-7344, pci 6110e & ni5411?

I am running win98 with my Labview 5.1. It running fine, but I would like to upgrade the os to windows 2000.
When I was running a check of the hardware, win2k said that the following hardware may not run:
pci-7344, pci-6110 & ni-5411.
will i need new drivers?
will i run into any problems?
any suggestions?
thanks!

Byron,
You should not have any problems when you upgrade your OS. Depending on what driver versions you have for that hardware, you may want to go ahead an upgrade your drivers anyway, though. The drivers for these devices are all available for free from our website at:

LabVIEW 3.1 SE: how to interface with Centronics

I would to interface my serial ADC (ADS7822) via
Centronics so I was wondering how I can do it
by usinf LabVIEW 3.1 Student Version.
Thanks in advance.

The printer port (Centronics) is parallel communication and you'll need a converter. The ones in my Black Box catalog (www.blackbox.com) are not cheap - ~U$100. Cheaper to buy another serial port card for the computer. You'd then have the problem of how to communicate with the parallel port. Version 3.1 is extremely old. With a newer LabVIEW version you'd have more options.

CPU-Usage during control of a DC Motor with the PCI-7344 board?

Hello!
I want do control a DC-motor (no stepper motor). Now i´m using the PCI-6527 board and simulating the delay between "high" and "low" on the Simulate-signal-vi. This works fine while no other process on the PC is running. The CPU-usage rises up to 100%. Is it possible to use the PCI-7344 board for controlling my DC-motor and having enough CPU resources to do other things like capturing pictures with a cam at the same time? The CPU is a Pentium 3 1Ghz.

The PCI-7344 is a perfect solution for your problem. This board is designed for motion control applications and it's running everything on its own DSP and CPU:
Trajectory Generation, PID control, limit switch monitoring and so on.
Thus the PC's CPU is free for other tasks. Please note that you need a position feedback signal from a quadrature encoder.

Problems with a PCI-7344 motion controller

Hi all,
I've run into a weird problem with a NI PCI-7344 motion controller, where I
have a program that provides the motion control for my program that works
reasonably well, but when I make minor changes gets motion errors. The changes
are not specifically to the motion parts, just changing a couple of globals
that provide communication with another part of the program (and another piece
of hardware). The errors I get indicate that I am trying to enable limits
switches at the wrong time in my program. I will add that I do not get any
errors when I go through the program in debug mode
Tnx,
P.W.Monroe

The portion of my program that gets the errors uses the "Flexmotion" Find Home
and Find Index routines, which are built into the 7344 controller. In the
exampes for using these VIs, they are followed by a loop that has a VI that
monitors the status of these VIs for completion, both move complete and Home or
Index Found. The globals that I mentioned are being used to terminate the loops
if an error condition occurs elsewhere, and do not cause the program to do
anything other than terminate looking at the status and then go into a wait
loop. It crashes when it goes into the loop when I substitute a different
global, which is baffling to me, as they aren't triggering something that would
result in a race condition.

How LV interfaces with a microcontroller (serial communication).

I am starting to design a system that uses an RFIC, a microcontroller and a VI to act as a user interface. The microcontroller outputs in RS232 to a Lantronix device which packages up the information and sends it over a network. I plan on using LV's VISA to locate the device. I have not worked with a system like this before and I would like to know how LV sees the data that is being sent over the network and how I can unpackage the data and make sense of it in LV, then output data to be sent to the uC. I would appreciate any suggestions anyone may have.

The Lantronix device will install a device driver to the PC that creates a virtual com port. LabVIEW will communicate with that com port (Let's say Com8) through VISA. The device driver will handle the communication with the Lantronix device over the network.
The Lantronix device I used is pretty sophisticated, and was not that easy to set up. It may also have other methods of communication such as talking to it TCP/IP. If I remember correctly, it also had a local terminal mode and a remote terminal mode.
In the end, once I figured out the trick to getting the device driver to work (the instructions were just not that obvious on how you had to set up the ports and open up the firewall to make it work), I was able to use it just like I said at the beginning as a Virtual com port. I've used other remote serial devices that were truly much more plug and play.

How to interface with Chameleon camera

Hi everyone,
I am trying to use Labview to control Chameleon camera, which is from Point Grey Research. I am using the ActiveX control interface and I have encounter a problem of using "Call Library Function" node. I am using that node to get the image array from a pointer and trying to display. However, the "Call Library Function" node doen't work.
I am wondering how can I get the image array from a pointer that is used by the FlyCapture?
Was there anyone experience the same thing?
Thanks.
Carson

CarsonZ,
Please check to see if your camera is supported by the Industrial Camera Advisor. Also, when you say that the Call Library Function node does not work, does it return a specific error message or just not return any data?
Lastly, is the FlyCapture application an ActiveX enabled application? If so you should be able to register for events and also pull the information from the application by running through this help document.

How to Interface with IP in Kernel

I have a unique problem regd solaris network stack.
I want to add a new protocol over solaris IP, say RIP.
How can it be done ?? Does Solaris IP use the published NPI interface ??
or does it use some other published interface ??
Can we write a streams module and push it over IP driver to get particular protocols packets from IP??
If i want to replace IPSec module of Solaris because of some proprietary feature enhancement, is it possible to do that ??

Limit Switches interfacing with PCI-7344

I am trying to figure out the best way to calibrate encoders with the PCI-7344 interface card. Should I setup my limit switches to stop the axis at the limit and then reset encoders there or what? Or should I have a home switch somewhere in the center of travel and let Labview reset the encoders at that point? The 7344 card has digital I/O but they are not configured as anything at the moment. I assume there is a vi to do this? What is the accepted way to do this?
Perry

Hi Perry,
What sort of behavior is your motion system going to have? Typically, you would want for one end (if linear) to be the home. So, I would probably approach it that way. But, what is your system going to be like? As for the digital I/O, there is a palette of VIs to handle this within the NI 73XX functions palette. See the pic.

Position Control of compumotor linear servo table and GV-U6E with PCI-7344

I'm referring PCI-7344 (not 7334).
I have the GV-U6E which is a drive only and does not possess control functionality. the drive only version does not store or use programs. So, serial commands can not be sent through COM port by LabVIEW even though A few basic commands can be emulated.
I am trying to do position control as I mentioned. For example, the motor should move A point to B point exactly with a certain speed. The points must be aboulte position.
I would like you to see the reference comment that I have been contacting with in your website forum.

Yes, we used an NI PXI-7344 motion control card with an NI UMI-7764 box connected to a Gemini GV-U12E servo drive. (which is a drive only.)
We did positional control in absolute position mode.
I can send you an AutoCAD schematic detailing how to connect the UMI-7764 to the Gemini GV servo drive.
In regard to the Rs232 interface to the GV servo drive,
the GV drive only model is "configurable" not "programmable". You can create unique GV configuration files with Compumotor's Motion planner then download the configuration via Rs232 using LabVIEW as desired. Or, using LabVIEW via Rs232 you can change individual GV drive parameters on demand,
or use the GV's two analog outputs back to LabVIEW's analog inputs to measure commanded motor current or torque, etc.etc.etc

How to achieve image using digital camera of USB-type interface through IMAQ PCI-1424 board.

1.Is it doable?
2.How to connect USB-type interface with IMAQ PCI-1424 board.
Thanks!

See the Developer's Zone (www.ni.com/zone) for specifics on USB (search for "USB").
"1.Is it doable?"
- In short "no".
- USB is similar to FireWire (IEEE 1394), and no framegrabber is required. We offer an IEEE 1394 IMAQ driver to interface FireWire cameras with LabVIEW & CVI.
"2.How to connect USB-type interface with IMAQ PCI-1424 board."
- You will need a USB driver for the camera. The 1424 is not required.
