Functionality
PRP IEC 62439-3 redundant communication
Redundant communication according to IEC 62439-3 PRP-0 and IEC 62439-3 PRP-1
parallel redundancy protocol (PRP) is available as an option when ordering IEDs. PRP
according to IEC 62439-3 uses two optical Ethernet ports.
IEC 62439-3 High-availabillity Seamless Redundancy (HSR)
Redundant station bus communication according to IEC 62439-3 Edition 1 and IEC
62439-3 Edition 2 High-availability seamless redundancy (HSR) is available as an
option when ordering IEDs. Redundant station bus communication according to
62439-3 uses two optical Ethernet ports.
Operation principle
PRP IEC 62439-3 redundant communication
The communication is performed in parallel, that is the same data package is
transmitted on both channels simultaneously. The received package identity from one
channel is compared with data package identity from the other channel, if they are the
same, the last package is discarded.
The RCHLCCH function block supervise the redundant communication on the two
channels. If no data package has been received on one (or both) channels within the
last 10 s, the output LinkAUp and/or LinkBUp is set to 0 which indicates an error.
