LabVIEW communication with S7 300 using PROFINET

[Mando_25]

I am communicating S7 300 PLC with LabVIEW software. I need to communicate with the PLC using the PROFINET communication. I know that we can communicate external devices with PLC using Profinet communication with the help of GSD file of the specific device. But here I need to communicate PLC with PC using Profinet communication for reading data from PLC registers. Please find me a solution.

You need a Profibus hardware interface to comminicate with Profibus devices. There are a few out there that come with limited LabVIEW support such as from Hilscher. We normally use the one from Kunbus which comes with a full LabVIEW interface library and is basically the same as resold by NI

Kunbus has other variants than PCI to sell but the status of those cards was always kind of not fully released in the past.
