The file DeviceIds.json represents a dictionary of Profinet Vendor- and DeviceIDs, collected from different sources.
The key represents either the GSDML filename or the SIEMENS ordernumber of the device. The value is a 32-bit hex value (0xAAAABBBB), representing the VendorID (A) and DeviceID (B) of the device.
The dictionary is used by the TcPnScanner to obtain the corresponding Vendor- and DeviceIDs when running a Profinet scan. Further devices may be added over time.
