If anyone has vi which can be used for this or any vi which can be modified to be used then it would be of grate help..

Your subject says DSC. Are you planning on using that or the LabVIEW library? I don't know about DSC but the LabVIEW code comes with some examples.

i will be using modview library itself..

Are you sure you are supposed to be using modbus?  The .pdf you attached doesn't mention modbus at all.

It does define a serial protocol that tells what bytes to send and receive.

Is this device something that was made in another country such as China?  Reading the .pdf, it is a poor translation to English, but actually not the worst documentation I have ever seen.

 I am sure about using modbus protocol.

Actually i got the documents from someone else so i dnt have any idea where the device was made.

Ask for more documentation, because what you have attached has nothing to do with Modbus.

In order to use modbus, you'll need some document that lists the address numbers for the various registers you want to access.

As for examples, the Modbus Library includes a few examples such as "MB Serial Master Query" for how to communicate with a Modbus slave device.
