hardware for these changes to take effect. However, unlike virtual
channels, you can set device parameters or accessory configuration
information programmatically inside a VI without running MAX.
Therefore, you can programmatically change these parameters in your VI
without resetting the hardware.
Refer to your NI-DAQ documentation and the DAQ section of the
LabVIEW Help, available by selecting Help»Contents and Index,
for more information about configuration.
RT Series DAQ VIs
RT Series DAQ VIs are available on the Functions»RT»RT Series DAQ
palette. Refer to the LabVIEW Real-Time Help, available by selecting
Help»LabVIEW Real-Time Help, for more information about the
LabVIEW RT VIs.
In addition to the RT Series DAQ VIs, LabVIEW RT includes the PID
Control Toolset, which includes functions for PID and Fuzzy Logic control.
The Fuzzy Controller VI requires information for a specific designed fuzzy
controller loaded from its corresponding data file (
*.fc ). Because the RT
Engine does not support file I/O, you must save this information as the
default values of the front panel controls of the Fuzzy Controller VI before
attempting to use it on the RT Series DAQ device. Refer to the PID Control
for G Reference Manual for more information about the PID Control and
Fuzzy Logic VIs.
