Text Based ADEs
You can use text based ADEs such as LabWindows/CVI, Measurement
Studio, Visual Basic, .NET, and C# to create code for using the
SCXI-1125.
LabWindows/CVI
LabWindows/CVI works with the
DAQ Assistant
in MAX to generate
code for a task. You can then use the appropriate function call to modify
the task. To create a configurable channel or task in LabWindows/CVI,
complete the following steps:
1.
Launch LabWindows/CVI.
2.
Open a new or existing project.
3.
From the menu bar, select
Tools»Create/Edit DAQmx Tasks
.
4.
Choose
Create New Task In MAX
or
Create New Task In Project
to load the DAQ Assistant.
5.
Configure the NI-DAQmx task following the instructions in the
Creating a Voltage Global Channel or Task
6.
The DAQ Assistant creates the code for the task based on the
parameters you define in MAX and the device defaults. To change
a property of the channel programmatically, use the
DAQmxSetChanAttribute
function.
Note
Refer to the
NI LabWindows/CVI Help
for more information on creating NI-DAQmx
tasks in LabWindows/CVI and NI-DAQmx property information.
Measurement Studio (Visual Basic, .NET, and C#)
When creating a task in Visual Basic .NET and C#, follow the general
programming flow in Figure 5-1. You can then use the appropriate function
calls to modify the task. This example creates a new task and configures an
NI-DAQmx channel on the SCXI-112511251125. You can use the same
functions for Visual Basic .NET and C#.
Programmable NI-DAQmx Properties
All of the different ADEs that configure the SCXI-1125 access an
underlying set of NI-DAQmx properties. Table 5-5 provides a list of some
of the properties that configure the SCXI-1125. You can use this list to
determine what kind of properties you need to set to configure the device
for your application. For a complete list of NI-DAQmx properties, refer to
your ADE help file.
