According to PROFINET standard a device must have the following types of MAC addresses:
- One unique MAC address for each port (Port MAC address)
- One unique MAC address for the interface itself (Interface MAC address)
Note
The interface MAC address may also be displayed as a Port MAC address in case the device has one port.
Port MAC addresses
For Siemens products, EPS provides the reserved addresses as input
parameter in EPS_APP_GET_MAC_ADDR function.
You can overwrite these addresses with your own MAC addresses for non-Siemens hardware products (e.g. Standard PC products based on Npcap driver or embedded hardware-specific products based on Intel I210 ("Springville") or Intel 82574L ("Hartwell")).
Interface MAC addresses
The Ethernet driver of the device provides interface MAC address as
input parameter in EPS_APP_GET_MAC_ADDR function.
You can overwrite this MAC address.
