reading online data via another software or .log file

[jftak01]

Hey:

I am running an experiment to measure motor (AC 3 phase Induction)during the test.

motor speed is controlled by a VFD.

Actually I can read all of needed parameters using a software(DriveView) for this VFD.

my problem is this:

I need to do some calculations on monitored parameters (such as voltage , Current, frequency,..) in DriveView. 

Is there any way that I can read online monitored data (in DriveView) using Labview???

Please contact me at jftak01@gmail.com , if you need more details.

waiting for your reply.

Hey jftak01,

The first step in reading data into LabVIEW is knowing where the data is coming from. Are you looking to read the data from a webpage, from a file, from another program, from an instrument, etc. These are all valid ways of bringing data into LabVIEW; and all require different means of doing so. If you have your data in a text file, you could do a simple read from text file, extract your data, and do your calculations. There are plenty of examples that demonstrate file i/o. If you are reading from a website, you could use the internet toolkit. If you are interested in reading from this third party program, you would likely want to use ActiveX (you would need to make sure this third party software has the appropriate ActiveX controls). So, where is this data that you are looking to bring into LabVIEW?

Thanks...

I have posted the same problem and have a great response on following link:

See you there.

One of the features listed for this motor controller is:

RS485 ModBus-RTU Communication Interface for Remote Control by PLC or Other Devices

Why not just read the values directy into LabView via ModBus using an RS-232/RS-485 converter and the MODBUS Library for LabVIEW?

BTW: They don't like it when you start two threads that are basically asking the same question...

thanks Ben..it's a great Idea if it works.!!

I just don't know how to analysis its data in Labview!!!  you know... in DriveView software I can see the voltage, current, power and other motor parameters easily ... every thing is readyin Driveview

Is it easy to get motor parameters by your procedure????

Would you please reply your answer on following link: http://forums.ni.com/ni/board/message?board.id=170&message.id=478020#M478020

because i like other guys see your idea , too...

I have uploaded some files and pictures overthere too

thank you so much.

sorry i made a mistake

I meant RTSLVU 

would you please comment on that link??

thanks

I used MODBUS.

Now, it works well.

Thank you all.
