stNum
— State number. The most recently received value in GOOSE message field stNum. The publisher increments stNum
each time that the state of one or more of the GOOSE message members is sent with a revised value.
sqNum
— Sequence number. The most recently received value in GOOSE message field sqNum. The publisher sets sqNum
to zero each time the state of one or more of the GOOSE message members is sent with a new value, and it increments it
whenever a GOOSE message is resent without any member value change.
IGMP
— Multicast (SSM and ASM) modes of R-GOOSE reception require that the N60 device subscribe to a multicast group
over the Internet Group Management Protocol (IGMP) enabled network. R-RxGOOSE## IGMP status On indicates that IGMP
negotiation with a network device (for example a router) was successful. In the case where setting R-RxGOOSE1 DST IP is
configured to a multicast address and this status indicates Off, R-GOOSE reception cannot be successful, and therefore
communication network diagnosis needs to be carried out. 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.
