[parthipan]

Hi,

  I need to develop a code which will control  any DMM instrument using IVI driver. does any one know how to write the wrapper for this

Do you want to write the IVI Driver itself in LV or just the wrapper alone?

Your wordings are not clear.

Hi,

 only wrapper but the same code should work for different model of iDMM(ex agilent and NI)

that is if my wrapper is open input to my wrapper is model no. It should open the particular model DMM.

I mean to say OPEN wrapper is generic to all DMM instrument.based on the input (Model no or something) provided to

the open wrapper it should call the particular model DLL

Maybe you can use an Enum consisting of all the available instrument model numbers.

Then, accordingly you can have different CS inside each of these will be the respective DLL.

This way, you can go on creating your wrapper for the generic iDMM Open function.

hi,

 I dont get it. what is CS .do u have any sample for it

[parthabe]

CS means Case Structure, ES means Event Structure, SR means Shift Register & so on...

You read this for more details.

I don't understand why you think you have to write anything. If you are familiar with IVI, you should know that all that you have to do is use the class driver that is on your palette. When you want to change to a different instrument, you change it in MAX.

The assignment of logical names, etc. is all done in MAX. open MAX and right click on "IVI Drivers". The window on the right side has help such as 'Logically name a driver session'. Follow the directions. You can also see this tutorial.
