Access Points Diagnostics; Redundant Communication; Iec 62439-3 Redundant Communication Prp; Routes - ABB REC670 Product Manual

Bay control REC670 2.2
Product version: 2.2.1
DHCP is available for the front port, and a device connected
to it can thereby obtain an automatically assigned IP-address.

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.
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 7.

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.
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.
IEC 61850 quality expander QUALEXP
The quality expander component is used to display the
detailed quality of an IEC/UCA 61850-9-2LE analog channel.
The component expands the channel quality output of a
Merging Unit analog channel received in the IED as per the
IEC 61850-7-3 standard. This component can be used during
the ACT monitoring to get the particular channel quality of the
Merging Unit.
IEC/UCA 61850-9-2LE communication protocol
Optical Ethernet port communication standard IEC/UCA
61850-9-2LE for process bus is supported. IEC/UCA
61850-9-2LE allows Non Conventional Instrument
Transformers (NCIT) with Merging Units (MUs) or stand-alone
MUs to exchange information with the IED, and simplifies SA
engineering. IEC/UCA 61850-9-2LE uses the same port as
IEC 61850-8-1.
LON communication protocol
Existing stations with ABB station bus LON can be extended
with use of the optical LON interface (glass or plastic). This
allows full SA functionality including peer-to-peer messaging
and cooperation between the IEDs.
SPA communication protocol
A single glass or plastic port is provided for the ABB SPA
protocol. This allows extensions of simple substation
automation systems but the main use is for Substation
Monitoring Systems SMS.
