controlling one pc/CVI application with another pc using GPIB

Dear all,

 

I have the following situation:

- Computer A having two NI-DAQ cards (6703 PCI type, each with 16 DA converters) and a CVI application controlling these cards. This computer also has a GPIB board installed.

- Computer B having also a GPIB board and is running a CVI application that is used in our lab to control various current/voltage sources and can read data from various measurement equipment.

 

What I would like to do is change the CVI application on computer A so it behaves as a virtual multi-channel voltage source that can be controlled by sending it (custom?) GPIB commands from computer B.

 

I guess the GPIB board in computer A must first be configured to be a listener, but then how do you process the commands sent to it?

 

Can anyone help me with some example programs that have a similar functionality? I'm a bit lost in all the info available on the net.

 

Hopefully there is someone out there that can give me a hint!

A much cleaner solution is to use the networked variable function library to communicate between applicaitons.

I've looked into it and the Network Variables can do the job indeed.

 

Thank you Layosh!
