General Integration Hints

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) = 0x02:0x00:0x00:0x00:0x00:0x03

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.

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.
