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No we do not publish the source code of the drivers.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

PCIe |  |
CPCI |  |
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.
