CHAPTER 6: ACTUAL VALUES

6.3.18 Parallel Redundancy Protocol (PRP)

The Parallel Redundancy Protocol (PRP) defines a redundancy protocol for high availability in substation automation
networks.

is a counter for total messages received (either from DANPs or from SANs) on Port A.
Total Received Port A
is a counter for total messages received (either from DANPs or from SANs) on Port B.
Total Received Port B
is a counter for total messages received with an error (bad port code, frame length too short).
Total Errors
is a counter for total messages received with an error on Port A (PRP frame, but port received through
Mismatches Port A
and LAN ID in the frame do not match).
is a counter for total messages received with an error on Port B (PRP frame, but port received through
Mismatches Port B
and LAN ID in the frame do not match).

6.3.19 TxGOOSE status

ACTUAL VALUES  STATUS  TxGOOSE STATUS
 TxGOOSE STATUS

The L90 is provided with optional IEC 61850 capability. This feature is specified as a software option at the time
of ordering. See the Order Codes section of chapter 2 for details.
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.
— The unicast mode of R-GOOSE transmission requires Address Resolution Protocol (ARP) for the resolution of the
ARP
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.
