controller connection

hamed71200 — Sat, 17 Mar 2012 22:32:15 GMT

Hi,

I have bought a stepper motor(http://www.newmarksystems.com/linear-positioners/nls4-series/)

and a controller (http://www.newmarksystems.com/motion-controllers/nsc-a1/).

How can I connect my controller to the labview???

I used find instrumentation driver in the software bt it cannot find controller driver. The stepper motor's company just gave me a .dll file and they said you can connect it to lsbview.

I would be gratefull if anyone can answer my question.

Regards,

Hamed

Their example programs provide LabVIEW examples. Did you look at them?

Thank you for your answer.

I don't know what is this .dll file for?

where is theses labview examples that you are talking about?

Right on the page for which you provided the link there is a link called "Libraries, Sample Code". If you download that file and uncompress it, you will find a "Sample Source Code" folder. In there are numerous examples. For instance, the "Serial" folder contains examples on communicating with the controller over a serial port, and has LabVIEW examples. The "USB" folder contains examples on communicating over a USB port. That example uses the DLL.

I 'm sorry, I made a mistake.

The file extension is .llb not .dll

what is this file for?

do I need the .dll file?

An .llb file is a library of LabVIEW vi's "zipped up" into a single file. LabVIEW can open it directly.

No you don't need a .dll. You were the one who brought that up.

Thank you a lot for your attention and I am sorry, that I am bothering you again.

If I understand you correctly, for connecting stepper motor and its controller to labVIEW, the .llb file is enough and we don't need the .DLL file.

That's what the 2nd line of my message said.

Ok, I got it.

I want to program the stepper motor to move for specific distance with spercific speed and logging the position in every second.

Can you tell me waht should I do? I mean that can you explain me the process step by step?

Thank you

Should I do the same thing as this video?

I tried to do this, but I the labview cannot find the driver for controller.

The llb that you downloaded only has a few basic functions. It looks like you need to send individual raw commands (with the 'Write Cmd' button) and the commands you need to send would appear to be listed in the manual. Unless someone has used the exact same controller as you and posts here, you will be pretty much on your own since you have the controller and no one else can test the code without the actual controller. I would suggest experimenting with the user provided program and then try to replicate the same thing with the LabVIEW code.

I have no idea where you placed the llb but doing exactly what is in the video is a bit silly. You do not have anything like a normal instrument/driver. That is something that you can create from the basic communication interface that the vendor has provided.

Note: There is a dll required. That is what the functions in the llb are connecting to.

hello, I met the same problem. That Llb file cannot be opened using labview, however, it can be opened using pspicem perhaps it's not a labview file

What .llb file are you trying to open, and what version of LabVIEW do you have?

Re: controller connection

zyb1003 — Wed, 09 May 2018 15:34:52 GMT

I have labview 2015, and I find that the file in the folder is not a .llb file but a lib file. Also, I didn't find out any labview sample code or VI library in the folder I installed.

By the way, the motion controller I use is NSC M series. I attached its installation file.

It doesn't appear that your model (which is discontinued) has any sample LabVIEW source code available.
