|NI-SCOPE (English | Japanese)|
ViStatus niScope_InitWithOptions (ViRsrc resourceName, ViBoolean IDQuery, ViBoolean resetDevice, ViString optionString, ViSession* newVi);
Performs the following initialization actions:
|resourceName||ViRsrc||Specifies the resource name of the device to initialize
For Traditional NI-DAQ devices, the syntax is DAQ::n, where n is the device number assigned by MAX, as shown in Example 1.
For NI-DAQmx devices, the syntax is just the device name specified in MAX, as shown in Example 2. Typical default names for NI-DAQmx devices in MAX are Dev1 or PXI1Slot1. You can rename an NI-DAQmx device by right-clicking on the name in MAX and entering a new name.
An alternate syntax for NI-DAQmx devices consists of DAQ::NI-DAQmx device name, as shown in Example 3. This naming convention allows for the use of an NI-DAQmx device in an application that was originally designed for a Traditional NI-DAQ device. For example, if the application expects DAQ::1, you can rename the NI-DAQmx device to 1 in MAX and pass in DAQ::1 for the resource name, as shown in Example 4.
If you use the DAQ::n syntax and an NI-DAQmx device name already exists with that same name, the NI-DAQmx device is matched first.
You can also pass in the name of an IVI logical name or an IVI virtual name configured with the IVI Configuration utility, as shown in Example 5. A logical name identifies a particular virtual instrument. A virtual name identifies a specific device and specifies the initial settings for the session.
|idQuery||ViBoolean||Specify whether to perform an ID query.
When you set this parameter to VI_TRUE, NI-SCOPE verifies that the device you initialize is a type that it supports.
When you set this parameter to VI_FALSE, the function initializes the device without performing an ID query.
VI_TRUE—Perform ID query
Default Value: VI_TRUE
|resetDevice||ViBoolean||Specify whether to reset the device during the initialization
Default Value: VI_TRUE
VI_TRUE (1)—Reset device
VI_FALSE (0)—Do not reset device
|optionString||Specifies initialization commands. The following table
lists the attributes and the name you use in the optionString
to identify the attribute.|
Default Values: "Simulate=0,RangeCheck=1,QueryInstrStatus=1,Cache=1"
You can use the option string to simulate a device. The DriverSetup flag specifies the model that is to be simulated and the type of the model. One example to simulate an NI PXI-5102 would be as follows:
Option String: Simulate = 1, DriverSetup = Model:5102; BoardType:PXI
Refer to the example niScope EX Simulated Acquisition for more information on simulation.
You can also use the option string to attach an accessory such as the NI 5900 to your digitizer session to allow the seamless use of the accessory:
Option String: DriverSetup = Accessory:Dev1
Refer to the example niScope EX External Amplifier for more information.
|vi||ViSession*||Returns a session handle that you can use to identify the device in all subsequent NI-SCOPE function calls.|
|Status||ViStatus||Reports the status of this operation. To obtain a text description of the status code,
To obtain additional information concerning the error
condition, use niScope_GetError
The general meaning of the status code is as follows:|
