Can I reset the network parameters using DCP and LabVIEW of the DF Profinet IO card?
A reset is possible. The Profinet protocol implements the DCP protocol.
A RESET is done by SET of constants "" as name and 0.0.0.0 as IP. See here: https://profinetuniversity.com/naming-addressing/profinet-dcp/
This command is only used by controllers to assign the devices in the network, so it is the task of the engineering tool or the controller to send these messages to identify the devices in the network.
If you use the card as a device it does not work.
If you use the card as a controller you can use LabVIEW to generate the reset in DCP.
In our LabVIEW driver under "5.1 PROFINET VISA Driver Menu" the DCP methods are listed, on page 14 of the PDF in the CD.

With the help of this function and the knowledge about the reset in DCP, you can generate a reset methode.
A reset in DCP is nothing else than a SET with a supplied empty string as name and 0.0.0.0 as IP address.
You can call this function at the desired place.
For example at startup.
So you need "Set Name" + constant and "Set IP" + constant to build a reset function. Done!
Why can't I recognise the Profinet IO device with my controller?
