Communicating with an Ethernet Controlled Instrument in LabVIEW

Hardware: PXI/CompactPCI>>Controllers

Problem:
Using LabVIEW, how do I read data from an instrument with an Ethernet connection?

Solution:
There are two ways to reference an Ethernet instrument in LabVIEW: 

• Create a VISA resource constant.  The instrument reference is TCPIP::xxx.xxx.xxx.xxx::INSTR, where the x's refer to the instrument's IP address.  This method does not require configuration in Measurement & Automation Explorer (MAX).  

  

• Create a new TCP/IP VISA resource in MAX.  Then reference the VISA Alias in LabVIEW instead of using the constant created in the previous step.  To setup the TCP/IP VISA resource, refer to the Ethernet Instrument Control Tutorial referenced below.
