4.4 USING THE DRIVER FUNCTIONS
The interactive example uses various driver functions of the LabView G driver. The following
two paragraphs details the inputs and outputs of two of typical VI’s used in the interactive exam-
ple: KepcoDCPwr Configure Voltage Level.vi (PAR. 4.4.1) and KepcoDCPwr Measure [MSR].vi
(PAR. 4.4.2). An overall block is provided for each function which shows inputs and outputs, fol-
lowed by detailed descriptions of inputs and outputs. A detailed block diagram with associated
text is also provided to show how the function is implemented.
4.4.1 KepcoDCPwr Configure Voltage Level.vi
This VI configures the DC voltage level the power supply is expected to generate.

See Table 4-2.
TABLE 4-2. KepcoDCPwr Configure Voltage Level.vi INPUT/OUTPUT DESCRIPTIONS
DESCRIPTION SYMBOL
channel name - ("") Passes the name of the channel on which to configure the voltage level. It is not required for
most supplies and is provided for compatibility.
Valid Channel Names: 1 - 27
Default Value: ""
level (0.0 volts) - Passes the DC voltage the power supply is to generate. The driver uses this value to set the
Voltage Level. The level is not checked by the driver function but is checked by the KLP or power supply.
Default Value: 0.0 volts
error in (no error) - The error in cluster can accept error information wired from VI’s previously called. Use this
information to decide if any functionality should be bypassed in the event of errors from other VI’s. The pop-up
option Error (or Explain Warning) gives more information about the error displayed (see Table 4-3).
VISA Session - The ViSession handle is obtained from the KepcoDCPwr Init or KepcoDCPwr InitWithOptions
function. The handle identifies a particular instrument session. Default Value: None
Model In - Model In is the type of Kepco power supply. This defines the capabilities and requirements in other
Kepco functions to insure proper operation of the command. This function works on All Kepco power Supplies:
BOP-HP, BOP-LP, KLP, STANDARD, MULTI and MULTI_PLUS. The MULTI type power supplies require a chan-
nel number to operate correctly. The constant is created by the Recognize Kepco model utility.
error out - The error out cluster passes error or warning information out of a VI to be used by other VI’s. The pop-
up option Explain Error (or Explain Warning) gives more information about the error displayed (see Table 4-3).
VISA Session Out - The ViSession handle is obtained from the KepcoDCPwr Init or KepcoDCPwr InitWithOp-
tions function. The handle identifies a particular instrument session. Default Value: None
Model Out - The Model Out handle is obtained from the KepcoDCPwr Init or KepcoDCPwr InitWithOptions func-
tion. The handle identifies a particular instrument. Default Value: None
channel name out - ("") Passes the name of the channel on which to configure the OVP limit.
Valid Channel Names: 1-27; Default Value: ""
