A VI initialization for 2 connected GPIB instruments

[keng]

I have two GPIB instruments connected to my PC.One is a TSX3510P supply unit and the other is a digital multimeter, Fluke 8842A. How do I create a VI initialization so that it can search and detect my two GPIB instrument address and display it on the Front Panel?

The attached VI does what you want. It works just like MAX's "scan for instruments" feature.

You could also use the VISA Find Resource function (Instrument I/O>VISA>VISA Advanced palette) and use the expression "GPIB?*INSTR". Also, if you VISA aliases like I tend to do, you can read the Visaconf.ini file as per the attached LabVIEW 6.1 example.
