"NPSV" communication

Shared variables icons in LabVIEW project

Create a network-published shared variable (NPSV)
RT procedure PC procedure

The network-published shared variable (NPSV) behaves like a global variable to link targets through the network.

Front-panel indicator LED with green bound variable indicator

Bind a PC VI front-panel indicator to a network-published shared variable (NPSV)
RT procedure PC procedure

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.

LabVIEW RT block diagram snippet: RT and PC read and write the same network-published shared variables

Network-published shared variable (NPSV)
RT code PC code

A network-published shared variable (NPSV) behaves like a global variable that links process loops residing in two or more network-connected targets.
