Lan to GPIB Controller software impact

[id]

I wrote a Labview program on a PC wiht an inernal GPIB Controller card to control a GPIB Electronic Load using NI VISA and vendor supplied Labview VIs that use NI VISA.  I now have to implement the same program on a laptop using a LAN to GPIB Converter from NI to talk to the Electronic Load. 

What is the difference in how this LAN to GPIB device gets programmed verses a direct gpib controller for the same instrument?  Is the code that I have written already not usable?  Do I have to write direct TCP/IP Commands now out of my Labview program?

Hi there,

The only difference between using a standard GPIB port and the ENET-GPIB is how you set it up and configure it within MAX. From there, it will behave exactly the same. All of the TCP/IP routing is done automatically.

So I can use the VISA Library for the instrument in labview and it will work for both GPIB or this Ethernet.  I just have to redefine the interface to switch between the two?

Sounds great.

You would change the resource only if you change the gpib address of the instrument or the controller number. If you use aliases, you wouldn't change your code at all.

I am also facing similar problem, Can you suggest the address / visa resource name used?

There was no real problem with the original question. Your question sounds off-topic so please start a new thread with some details.

I have written a LABVIEW progam to control a device using GPIB interface.Now I ned to modify it for using it though a GPIB- ENET 100 device. How should I do that? What Address format to use in Visa Rsource?

As already said, you don't change a thing.
