Ethernet; Station Communication - ABB RES670 Product Manual

Phasor measurement unit RES670 2.2
Product version: 2.2
Only GPS and IRIG-B (Optical IRIG-B 00X is recommended),
with IEEE1344 support, are the acceptable time
synchronization sources for synchrophasor measurement
applications and RES670 supports both.
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.

17. Ethernet

Access points
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 are allocated if redundant
communication is activated for the access point.

Access points diagnostics
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.
Redundant communication
IEC 62439-3 redundant communication PRP
Redundant communication according to IEC 62439-3 PRP-0,
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-availability seamless redundancy HSR
Redundant station bus communication according to IEC
62439-3 Edition 2 High-availability seamless redundancy
(HSR) is available as an option when ordering IEDs.
M11345-3 v11
Redundant station bus communication according to IEC
62439-3 uses two optical 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.
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 6.

18. Station communication

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
• C37.118 communication protocol
Several protocols can be combined in the same IED.
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
