Self-healing Ethernet ring solution

All communication connectors, except for the front port
connector, are placed on integrated optional communication
modules. The relay can be connected to Ethernet-based
communication systems via the RJ-45 connector (100Base-TX)
or the fiber optic LC connector (100Base-FX). If connection to
serial bus is required, the 9-pin RS-485 screw-terminal can be
used. An optional serial interface is available for RS-232
communication.
Modbus implementation supports RTU, ASCII and TCP modes.
Besides standard Modbus functionality, the relay supports
retrieval of time-stamped events, changing the active setting
group and uploading of the latest fault records. If a Modbus
TCP connection is used, five clients can be connected to the
relay simultaneously. Further, Modbus serial and Modbus TCP
can be used in parallel, and if required both IEC 61850 and
Modbus protocols can be run simultaneously.
The IEC 60870-5-103 implementation supports two parallel
serial bus connections to two different masters. Besides basic
standard functionality, the relay supports changing of the active
setting group and uploading of disturbance recordings in IEC
60870-5-103 format. Further, IEC 60870-5-103 can be used at
the same time with the IEC 61850 protocol.
DNP3 supports both serial and TCP modes for connection up
to five masters. Changing of the active setting and reading fault
ABB
records are supported. DNP serial and DNP TCP can be used in
parallel. If required, both IEC 61850 and DNP protocols can be
run simultaneously.
615 series supports Profibus DPV1 with support of SPA-ZC
302 Profibus adapter. If Profibus is required the relay must be
ordered with Modbus serial options. Modbus implementation
includes SPA-protocol emulation functionality. This
functionality enables connection to SPA-ZC 302.
When the relay uses the RS-485 bus for the serial
communication, both two- and four wire connections are
supported. Termination and pull-up/down resistors can be
configured with jumpers on the communication card so external
resistors are not needed.
The relay supports the following time synchronization methods
with a time-stamping resolution of 1 ms.
