DF PROFINET IO

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?

The device only becomes active when, for example, the Kunbus example project is executed.

Have a look at this article:

DF PROFINET IO | Quick Start - LabVIEW Driver

I need the source code for the driver for my application. Is it possible?

No we do not publish the source code of the drivers.

Which is the controller port and which is the device port?

GSDML file provided by Kunbus Configurator III only has Port1 configured. Is there any reason why we can't utilize both ports?

There is nothing wrong with the GSDML file. The hardware can be used both as a controller and as a device. There is no GSDML file for the master. The master must only be configured via KUNBUS CONFIGURATOR III.
