Station Communication - ABB REC650 Product Manual

Bay control REC650
Product version: 1.1
Time-tagging of internal events and
disturbances are an excellent help when
evaluating faults. Without time
synchronization, only the events within the
IED can be compared to one another. With
time synchronization, events and
disturbances within the entire station, and
even between line ends, can be compared at
evaluation.
In the IED, the internal time can be
synchronized from a number of sources:
• SNTP
• IRIG-B
• DNP
• IEC60870-5-103
Parameter setting groups ACTVGRP
Use the four sets of settings to optimize the
IED operation for different system conditions.
Creating and switching between fine-tuned
setting sets, either from the local HMI or
configurable binary inputs, results in a highly
adaptable IED that can cope with a variety of
system scenarios.
Test mode functionality TESTMODE
The protection and control IEDs have many
included functions. To make the testing
procedure easier, the IEDs include the feature
that allows individual blocking of a single-,
several-, or all functions.
There are two ways of entering the test mode:
• By configuration, activating an input
signal of the function block TESTMODE
• By setting the IED in test mode in the
local HMI
While the IED is in test mode, all functions
are blocked.
Any function can be unblocked individually
regarding functionality and event signaling.
This enables the user to follow the operation
of one or several related functions to check
functionality and to check parts of the
configuration, and so on.

Change lock function CHNGLCK
Change lock function (CHNGLCK) is used to
block further changes to the IED
configuration and settings once the
commissioning is complete. The purpose is to
block inadvertent IED configuration changes
beyond a certain point in time.
Authority status ATHSTAT
Authority status (ATHSTAT) function is an
indication function block for user log-on
activity.
Authority check ATHCHCK
To safeguard the interests of our customers,
both the IED and the tools that are accessing
the IED are protected, by means of
authorization handling. The authorization
handling of the IED and the PCM600 is
implemented at both access points to the IED:
• local, through the local HMI
• remote, through the communication ports

communication
IEC 61850-8-1 communication
protocol
The IED supports the communication
protocols IEC 61850-8-1 and DNP3 over TCP/
IP. All operational information and controls
are available through these protocols.
However, some communication functionality,
for example, horizontal communication
(GOOSE) between the IEDs, is only enabled
by the IEC 61850-8-1 communication protocol.
The IED is equipped with an optical Ethernet
rear port for the substation communication
standard IEC 61850-8-1. IEC 61850-8-1
protocol allows intelligent electrical devices
(IEDs) from different vendors to exchange
information and simplifies system
engineering. Peer-to-peer communication
