LabVIEW - IO Controls and Indicators 

LabVIEW - I/O Controls and Indicators
We can use the I/O controls on the I/O and Classic I/O palettes with the functions for acquiring data, sharing data between applications, and controlling instruments. We can use the I/O controls to specify the instrument or device resource we want to communicate with.
We can use the waveform control to hold acquired data for analysis and display.
We can use the controls located on the DAQmx Name Controls palette to access the tasks, global channels, physical channels, terminals, scales, devices, and switch resources we configure using Measurement & Automation Explorer (MAX) and the DAQ Assistant.
Note (Windows) LabVIEW supports NI-DAQmx and the DAQ Assistant.
(Linux) LabVIEW supports NI-DAQmx but not the DAQ Assistant.
(macOS) LabVIEW supports NI-DAQmx Base but not the DAQ Assistant.
We can use the VISA resource name and IVI logical name controls to access the VISA aliases or logical names we configure using MAX.
We can use the FieldPoint I/O point control to access the FieldPoint items we create and configure using MAX.
We can use the IMAQ session with image acquisition boards.
We can use the Motion resource I/O control to access a motion resource we configure using MAX. Any items we configure in MAX appear as options in the I/O control pull-down menu.
We can use the shared variable control to select, browse to, or enter shared variables for use in VIs.
We can use any of the other controls in the palette to access names or resources associated with them.
After we select an I/O control, configure it for use with the I/O VIs that communicate with the device or instrument.
Note Many I/O name controls are available on all platforms. We can develop I/O VIs on any platform that can communicate with devices that are platform-specific. However, if we try to run a VI with a platform-specific I/O control on a platform that does not support that device, we will receive an error.
Some of the controls allow us to select multiple defined names. We can use the Operating tool to click the control, select Browse from the pull-down menu, and press the Ctrl key.
Refer to the respective toolkit, module, or driver documentation for more information about LabVIEW add-ons.
