Owning Palette: Data Communication VIs and Functions
Requires: Base Development System. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the DataSocket VI and functions to pass data between VIs programmatically.
The VI and functions on this palette can return networking error codes.
| Note LabVIEW 64-bit does not support using DataSocket connections to an OPC server. |
