Line distance protection REL650 ANSI
Product version: 1.3
Parameter setting groups ACTVGRP
Use the four different groups of settings to optimize the IED
operation for different power 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 be applied to a variety of power 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 all functions except
the function(s) the shall be tested.
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 protection 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.
Forcing of binary outputs, wether from the LHMI or from the
PCM600 is only possible when the IED is in test mode.
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.
The change lock function activation is normally connected to a
binary input.
Authorization
The user categories and roles with user rights as defined by IEC
62359–8 for role based access control are pre-defined in the IED.
The IED users can be created, deleted and edited only with
PCM600.
Password policies are set in the PCM600 IED user management
tool.
At delivery, the IED user has full access as SuperUser until users
are created with PCM600.
Authority status ATHSTAT
Authority status ATHSTAT function is an indication function block
for user log-on activity.
ABB
User denied attempt to log-on and user successful log-on are
reported.
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
The IED users can be created, deleted and edited only with
PCM600 IED user management tool.

AUTHMAN
This function enables/disables the maintenance menu. It also
controls the maintenance menu log on time out.
FTP access with SSL FTPACCS
The FTP Client defaults to the best possible security mode when
trying to negotiate with SSL.
The automatic negotiation mode acts on port number and server
features. It tries to immediately activate implicit SSL if the
specified port is 990. If the specified port is any other, it tries to
negotiate with explicit SSL via AUTH SSL/TLS.
Using FTP without SSL encryption gives the FTP client reduced
capabilities. This mode is only for accessing disturbance recorder
data from the IED.
