MAC Address
when the configuration option for LLDP MAC address generation is enabled, MAC addresses for ports are calculated from the base MAC address
this option is enabled by default and can be disabled by (goal_pnioCfgLldpGenMacSet)
calculation of MAC addresses
============================
MAC (device) = 0x02:0x00:0x00:0x00:0x00:0x01
MAC (port-001) = 0x02:0x00:0x00:0x00:0x00:0x02
MAC (port-002) = 0x02:0x00:0x00:0x00:0x00:0x03NVS Storage
via PROFINET (DCP) values can be set in the device which optionally need to be stored permanently
to be conform to the PROFINET standard, this process needs to be executed timely and should not block normal device operation for more than 200ms
BACKGROUND: in the conformance test it is checked if a DCP set request is processed and answered within a time window of 500ms
Firewall Settings
GOAL PROFINET uses the following Ethertypes.
Ethertype | Description | Note |
|---|---|---|
0x0800 | Internet Protocol version 4 (IPv4) | only for GOAL managed TCP/IP Stacks |
0x0806 | Address Resolution Protocol (ARP) | only for GOAL managed TCP/IP Stacks |
0x8100 | VLAN-tagged frame (IEEE 802.1Q) | only if not removed by receive logic |
0x8892 | PROFINET Protocol |
|
0x88cc | Link Layer Discovery Protocol (LLDP) |
|

Additionally GOAL PROFINET uses the following UDP ports.
UDP Port | Description |
|---|---|
0x8894 | RPC port (34964, according to IANA) |
0xc000 | RPC responder port (49152, according to IANA) |

Certification Notes
Documentation
During the Conformance Test the behavior of the cyclic data is checked in the
following situations:
PLC enters state 'stop'
AR is closed
This behavior must be defined in the device manual. If not changed, the GOAL
PROFINET stack handles the situations in this way:
PLC enters state 'stop'
Input data values don't change.
AR is closed
Input data values are not longer available in memory, zeroed values are
reported.
