The IED supports SNTPv4 (RFC2030).

Precision time protocol PTP
PTP according to IEEE 1588-2008 and specifically its profile
IEC/IEEE 61850-9-3 for power utility automation is a
synchronization method that can be used to maintain a
common time within a station. This time can be
synchronized to the global time using, for instance, a GPS
receiver. If PTP is enabled on the IEDs and the switches
that connect the station are compatible with IEEE 1588, the
station will become synchronized to one common time with
an accuracy of under 1us. Using an IED as a boundary
clock between several networks will keep 1us accuracy on
three levels or when using an HSR, 15 IEDs can be
connected in a ring without losing a single microsecond in
accuracy.

Access points
GUID-6E5D2696-A8EE-43E7-A94B-69C3D0612127 v3
An access point is an Ethernet communication interface for
single or redundant station communication. Each access
point is allocated with one physical Ethernet port, two
physical Ethernet ports (marked A and B) are allocated if
redundant communication is activated for the access point.

Access points diagnostics
GUID-20F64A6D-AA8C-47D7-AA7D-4810996B2FF2 v3
The access point diagnostics function blocks (RCHLCCH,
SCHLCCH and FRONTSTATUS) supervise communication.
SCHLCCH is used for communication over the rear Ethernet
ports, RCHLCCH is used for redundant communications
over the rear Ethernet ports and FRONTSTATUS is used for
communication over the front port. All access point function
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
GUID-A90FDBA7-D4D7-4CBD-9F05-13DCC9971779 v9
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.
GUID-D87005A3-826E-4EB4-9B3D-9C6222CFEF6C v1
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
GUID-95F9C7BA-92F8-489F-AD0A-047410B5E66F v1
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
6 .
