A.2 LABVIEW LIBRARY
A.2.1 LABVIEW LIBRARY OVERVIEW
The LabView Library provides functions to be used under National Instruments LabView 5.0
control software package for windows. The functions provide a means of controlling Kepco
power supplies.
Most functions contain the following parameters in addition to any function specific parameters:
•
Instrument handle In
• Instrument handle out
• Error in
• Error out
A.2.1.1 Instr handle in
This is a unique instrument identifier, which is required by most functions. Its value is obtained
from the AutoCon or Initialize function, at the Instr handle out terminal
A.2.1.2 Instr handle out
This is a unique instrument identifier returned by the initialize or AutoCon function, and is used
by other functions as the Instr handle in
A.2.1.3 Error in
This is the input error cluster, which passes error information to a function. It is usually wired to
the error out terminal of a preceding function.
A.2.1.4 Error out
This is the output error cluster, which passes error information after a function call. It can be
used to pass the information from a function to the error in terminal of the next function called.
