using SCPI command in labview

[Pimi810]

Hi.

I've found an instrument driver for keithley 6221 on keithley.com.

Here is a question: I wana to control this model directly by using SCPI command instead of instrument driver. But,  I don't know how can I do this in Labview 8.0.

Tnx.

An  instrument driver written in Labview, is not the same as a instrument driver used by say Windows. A Labview instrument driver uses standard Labview functions to send SCPI commands to the instrument. You can learn a lot about the instrument by looking into the Labview instrument driver, and how it sends the commands to the instrument. But having the instrument programming manual at hands is also important.

Since you don't know how to send commands in LabVIEW, I question your decision to not use the driver but in any case, you just wire the command to the 'Write Buffer' input of a VISA Write function.

On your instrument driver palette is a native LabVIEW driver (not IVI like the Keithley) for the 34401. Look at the block diagrams of the functions and look at the examples on how to build a driver at the Instrument Driver Network.
