Hello,
I don't think there is a VI that already does that, but LabVIEW does offer ways to communicate with PLCs. I noticed you have this other thread in which it seems that Daniel already pointed you the right way (I would have most probably pointed you to the same articles).
In fact, the LabVIEW Datalogging and Supervisorty Control module (DSC) used in both articles includes a template and examples about how to establish this type of communication.
Please review the information provided by Daniel and let us know if you still have questions.
Regards,
Camilo V.
