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)

Code Block
calculation of MAC addresses ============================ MAC (device) = 0x02:0x00:0x00:0x00:0x00:0x01 MAC (port-001) = 0x02:0x00:0x00:0x00:0x00:0x02 MAC (port-002) = 0x02:0x00:0x00:0x00:0x00:0x03

NVS 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)

Table: Firewall Ethertypes

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.
