How can I do Telnet communication in modern versions of LabVIEW?


Telnet VI's are no longer included in any version of LabVIEW past 2014. Telnet support for newer versions of LabVIEW  has been depreciated by NI, see the following article. If you need Telnet support in newer versions of LabVIEW (for example when upgrading legacy code), there is a workaround, but it is not officially supported by NI.

Workaround for accessing Telnet VI's in LabVIEW 2015 and higher

1. Download LabVIEW 2014 or lower to get access to the Telnet VIs. 2014 is recommended as it contains the latest released version of the Telnet VIs

2. Find the location of the Telnet VI's and save it to a custom location that will not be tampered with.

3. Add the aforementioned path to the VI search paths under tools.
