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 may 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

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 according to GOOSE is part of
the standard. Disturbance files uploading is
provided.
Disturbance files are accessed using the IEC
61850-8-1 protocol. Disturbance files are
