METERING CHAPTER 6: ACTUAL VALUES
6
This status is relevant to R-GOOSE reception when configured for SSM or ASM reception modes. It is not relevant for GOOSE
or for R-GOOSE in unicast reception mode.
ARP — The unicast mode of R-GOOSE transmission requires Address Resolution Protocol (ARP) for the resolution of the
network layer address into the MAC layer address. R-TxGOOSE## ARP status On indicates that ARP responses are being
received and the destination MAC address for R-GOOSE transmissions has been obtained. This status remains Off if
TxGOOSE## is not configured for R-GOOSE. It also remains Off if setting R-TxGOOSE1 DST IP is set to a multicast address. In
the case where setting R-TxGOOSE1 DST IP is configured with a unicast address and this status indicates Off, TxGOOSE##
transmission will be off, and therefore communication network diagnosis needs to be carried out.
This status is only applicable for R-GOOSE transmission with setting R-TxGOOSE1 DST IP set to a unicast IP address. It is not
applicable for GOOSE or for R-GOOSE when setting R-TxGOOSE1 DST IP is multicast.
