Version 2.2
blocks include output signal for denial of service. To get this
denial of service, that is reported on the communication, the
DOSALARM output from these blocks must be connected to
a communication function.
For RSTP, the frame error rate on an
individual link cannot be extrapolated
accurately to that of which is received by
the IED. Hence, the frame error rate on link
A (LCCH.FerCh) and the frame error rate
on link B (LCCH.RedFerCh) cannot be
calculated and are 0 always.
Redundant communication
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/Galvanic (RJ45)
Ethernet ports.
HSR IEC 62439-3 High-availability seamless redundancy
Redundant station bus communication according to IEC
62439-3 Edition 2 High-availability seamless redundancy
(HSR) is available as an option when ordering IEDs.
Redundant station bus communication according to IEC
62439-3 uses two optical/Galvanic (RJ45) Ethernet ports.
The HSR ring supports the connection of up to 30 relays. If
more than 30 relays are to be connected, it is recommended
to split the network into several rings to guarantee the
performance for real-time applications.
RSTP Rapid spanning tree protocol
Rapid Spanning Tree Protocol (RSTP) is a network protocol
built for loop-free network topology and redundancy/backup
connections between switches.
• Support for RSTP is available on the Station level network
communication.
• RSTP is only available on the Access Point (AP) 1 or
Access Point (AP) 3. AP1 uses port 1 and port 2; AP3
uses port 3 and port 4.
• RSTP can be configured using Ethernet configuration
Tool (ECT) and PST in PCM600.
Routes
A route is a specified path for data to travel between the
source device in a subnetwork to the destination device in a
different subnetwork. A route consists of a destination
address and the address of the gateway to be used when
sending data to the destination device, see Figure 14.

Communication protocols
Each IED is provided with several communication interfaces
enabling it to connect to one or many substation level
systems or equipment, either on the Substation Automation
(SA) bus or Substation Monitoring (SM) bus.
Available communication protocols are:
• IEC 61850-8-1 communication protocol
• IEC/UCA 61850-9-2LE communication protocol
• LON communication protocol
• SPA communication protocol
• IEC 60870-5-103 communication protocol
• DNP 3.0 communication protocol
Several protocols can be combined in the same IED.
The LPHD.PhyHealth reflects the physical
health of the IED. The status is set to Alarm
when there is an internal failure in the IED
or Warning if any active communication link
fails.
IEC 61850-8-1 communication protocol
IEC 61850 Ed.1 or Ed.2 can be chosen by a setting in
PCM600. The IED is equipped with up to six (order
dependent) optical Ethernet rear ports for IEC 61850-8-1
station bus communication. The IEC 61850-8-1
communication is also possible from the electrical Ethernet
front port. IEC 61850-8-1 protocol allows intelligent
electrical devices (IEDs) from different vendors to exchange
information and simplifies system engineering. IED-to-IED
communication using GOOSE and client-server
communication over MMS are supported. Disturbance
recording file (COMTRADE) uploading can be done over
MMS or FTP.
