"RT-PC" communication

Use the "Set Time" function to adjust the RT system time to match the (assumed accurate) PC system time. Restart the RT target to save the current RT time to be reloaded on each reboot of the Academic RIO Device.
Transfer data, commands, and status between the RT target and a host system.
The network-published shared variable (NPSV) behaves like a global variable to link targets through the network.
A quick and easy way for a PC HMI (human-machine interface) VI to observe the state of an RT-hosted network-published shared variable (NPSV) without creating any block diagram code; an alternative to programmatically accessing the NPSV value.
A network-published shared variable (NPSV) behaves like a global variable that links process loops residing in two or more network-connected targets.
Use the NPSV programmatic API (application programmer's interface) VIs as an alternative method to a shared variable node.
Send command and status messages through a low-latency lossless network-based data communication channel between the RT target and PC host system.
Efficiently transfer blocks of data between the RT and PC by network streams.
