Need recommendation for hardware and software

[ossoo]

Hi all,

I am doing a project related to current control.

The purpose is to keep the current at constant. So I measure the current and get the value; and send a analog signal to tell our machine to discharge or to charge in order to keep the current at constant. I need to write the program to give analog signal to machine based on the current input.

Also, the machine can communicate with user. User can monitor the machine operation statuse and current level, etc.

I want to use LabView to program, since it doesn't cost a lot of time. I saw there is LabView RT LabView FPGA, etc. I am confused whether all of these are just diffrent function for LabView or different software. Which one I should use?

For hardware, I have no idea what is compactible with LabVeiw. What I should use?

I am totally new to this. I'll appreciate a lot if anyone can give suggestions.

Thanks

I would recommend having a look at the C-Series Modules. You can then either use the USB Single Module Carrier, Wi-Fi Single Module Carrier, the CompactDAQ platform or the CompactRIO platform. Here is a page that gives a detailed explanation:

C Series Hardware

For your application, you will definitely need LabVIEW. If you decide to go with the cRIO platform, then you will need LabVIEW RT. If you have any questions after reading through, please ask.

Hi Adnan,

Actually, what I need is like embeded. All the function, like get current signal and then send out corresponding signal to control another unit, will goes to the whole system.

What the user need to do is turn on the circuit breaker, the system will run itself and no computer is needed. The computer is just optional if the user want to monitor, the signal can send via Ethernet or RS232, etc.

Do you have any suggestions?

Thanks

Hi ossoo,

What you will probably want in that case is a CompactRIO or a Single-Board RIO.  These systems will require at least the Real-Time Module, which is an add-on to LabVIEW.  You may also want the FPGA module if you're looking at doing higher speed control.  They both are capable of running without a computer as well as communicating back to a computer via Ethernet or RS232.
