On the block diagram, wire the iteration counter to the numeric indicator icon The structure tunnel appears as a solid block on the border of the while loop. The block is the color of the data type wired to the tunnel. Data passes out of a loop after the loop terminates. In...

The NI Timestamp VIs, located in the vi.lib/ addons/rt/_RTUtility.llb, read the Time Stamp Counter register from the Pentium processor of RT targets for every loop iteration. Refer to the NI Timestamp Code Timer VI located in the examples/Real-Time/ RT Timing.llb for an example using...
Variable Client Support 1.0.0 Broadcom 57xx Gigabit Ethernet driver 1.0.1.3.0 T5 and T6 Methodology and Considerations In test T5 and T6, NI used nonbuffered, network-published shared variables of the Waveform of Double datatype. T5 and T6 Hardware/Software Configuration ...
For the network-published shared variable case, an NPL runs on the host system and reads from the variable in a free-running while loop. For the real-time FIFO VI test, the NPL runs on the real-time system, checking the state of the FIFO at a given rate, reading all available data,...
You should putWrite Delimited Spreadsheet.viout of the loop (Figure 38). Putting the VI inside the loop is not the good way of using it. Because LabVIEW at every iteration would open-write-close the file if it is inside the loop. This is not good in terms of VI efficiency. ...
