integrate Motion control with LabVIEW RT and Ardence RTX - need a simple and cost effective solution

[CODE WARRIOR]

Hi, we like to control servo / stepper motor drives (10 or more)

We already have a motor drive, controller and interface software through windows.

To ensure reliability, robustness and stability of the system now we are planning to move to LabVIEW RT based software running under

Ardence RTX along with windows.

 

Now we have to integrate the hardware to run with Ardence RTX and LabVIEW RT.

We require a suitable and simple approach to solve this problem.

Thanks

CODE WARRIOR Hello,

What programming language did you develop the current software in, LabVIEW? There are two different flavors of Real-Time that National Instruments offers, ETS and RTX. I will explain both and you will let me know which works for you.

ETS: This converts a dedicated PC or National Instruments Hardware target into a DEDICATED Real-Time Target. This means the target will run only LabVIEW Real-Time. 
RTX: RTX allows users run a Real-Time Operating System in parallel with Windows. It gives you the ability to do your deterministic operations while viewing the User Interface of your application on the same computer, at the same time. You can find more information on that here as well.

After you take a look at both, you will see that it generally depends on which platform you want to develop on that will determine the way forward. If going the RTX route, there might not be much change required besides making sure your computer can run RTX, installing the software, and running your application. However, if going the ETS route, you will have to make sure your application can run on one of the dedicated real-time targets before purchase.

Please keep us posted.

Thanks. I have chosen RTx. I'm using LabVIEW RT and LabVIEW FPGA.

The GUI is windows based. The motion control and FPGA  are RTx based.

Is there any way to develop device drivers for the custom hardware in RTx. For example motion controller hardware, FPGA hardware, PCI hardware.

Is there a possibility to use custom FPGA boards to use with LabVIEW FPGA.

Please send me some links

Thanks

CODE WARRIOR Hello.

You are able to develop device drivers for your custom hardware using the NI Measurement Hardware Driver Development Kit.

However, it is not possible to use custom FPGA boards with LabVIEW FPGA. The FPGA boards have to be one of our R Series boards. Here are some links that should shed some light on the Measurement Hardware DDK.

Please post if you have further questios.

Thanks. I have the windows DLL for the custom harware board. I want to access it from the LabVIEW RT environment.

Please let mw know if this is possible.

Thanks
