1.4 T300 Configuration Principle

The T300 is delivered with a default factory configuration corresponding to the
options ordered.

This initial configuration should then be customized to adapt it to the user
application and requirements.

There are some tools for this purpose:
 Easergy Builder: Engineering tool for adding or customizing specific

operational options adapted to the application. Easergy Builder generates a
custom configuration for the T300 based on the initial configuration modified by
the addition of these options.

 SAT: engineering tool for defining / changing the equipment's security policy

and roles assigned to users.

 T300 Web server: Commissioning tool for the end user. Using the

configuration set up in Easergy Builder and loaded onto the equipment, the
user can set the parameters for the T300 application program via the Web
server. This step consists in customizing the parameters of the various
functions, such as fault current detection, communication, switch control,
measurement, etc.
In contrast to Easergy Builder, the Web server does not allow functions to be
added to the equipment. It only allows parameters to be set and customized
for the application associated with the functions already selected.

1.4.1 Engineering in Easergy Builder

Before using the equipment, a certain number of functions need to be configured in
Easergy Builder. These functions are not included in the factory configuration as
they depend on the customer application.

The functions that requiered to be added/modified in Easergy Builder are listed
below:

1.4.1.1 Adding/Deleting Channel and Modems

The setting of Channels and existing modems in the default configuration can be
done via the T300 Web server. However, the addition or replacement of modems or
the creation of Channels for the SCADA link, can only be done via Easergy Builder.

Refer to the Easergy Builder User Manual for more details on these custom
settings.

1.4.1.2 T300 Synchronization

The default configuration does not include device synchronization.
The choice of synchronization source can only be configured in Easergy Builder.
The Web server only allows the synchronization parameters to be set once the
function has been configured in Easergy Builder.

There are three possibilities for synchronizing the RTU:

 Automatically by the communication protocol (via the SCADA)
 Through an SNTP server, if the RTU is connected to an IP network.
 By GPS satellites, if the HU250 module includes a 4G modem with GPS

option.

You can define two channels of synchronization, the primary device and the
secondary device.
The secondary device will be used if the primary device is unavailable.

Instructions on how to configure synchronization are given in the T300 Quick Start
Guide (NT00383-xx). Refer to this document for more information.

Presentation General description

1.4.1.3 Sequence of Events (SOE)

An events file is automatically created in the T300 default configuration. This file
corresponds to standard use of the equipment and includes a number of data for
which events are generated on change of states.
The engineering phase is to modify or add additional variables to the file or to create
additional events files (eg measures backup file), or to change the default storage
files.
The total capacity of event files is limited to maximum 4 files.
Easergy Builder allows the management, creation or modification of these events
files.
Note that this management cannot be done via the Web server. The Web server
can only be used to operate these events files, i.e. consulting, downloading, or
deleting them.

Instructions on how to configure the SOE option are given in the T300 Quick Start

Guide (NT00383-xx). Refer to this document for more information.

1.4.1.4 The Master and Slave protocols

The default configuration of the equipment is provided without addressing for the
protocol since it must be adapted to the SCADA type used or the type of slave to
include in the configuration.

 The Master protocols:
For Master protocols, the engineering phase is to create first of all slave devices in
the system and the data that will be associated to these Devices. The data to create
depend on the application and the connected device type.

The addressing protocol will have to be set for all the data you wish to report the
statements on the T300.

The list of master protocols that can be used is as follows:

o IEC 60870-5-104
o DNP3
o Modbus
o IEC 61850 Client

 The Slave protocols:
For slave protocols, the engineering phase consists of selecting in the system
database, the datas that have to be reported to the SCADA and then to define the
corresponding protocol addressing.

The list of slave protocols that can be used is as follows:

o IEC 60870-5-101
o IEC 60870-5-104
o DNP3
o Modbus
o IEC 61850 Server

Instructions on how to configure the Master and Slave protocol addresses are given
in the T300 Quick Start Guide (NT00383-xx). Refer to this document for more
information.

NT00378-EN-03

1.4.1.5 Personalization of LEDs

Some indicators used in front panel of the product and external lights can be
customized to define the data that will trigger the lighting of these LEDs. This
operation is made during the engineering phase via Easergy Builder advanced tool.

Presentation General description

1.4.1.6 Management of specific commands

A specific management function related to the switch controls voltage can be
configured in the engineering phase via Easergy Builder.

Instructions on how to configure this specific command management option are
given in the Easergy Builder User Manual. Refer to this document for more
information.

1.4.1.7 Calculation Formulae

The calculation formulae are used to carry out math, combinational logic operations
or others on T300 data in order to perform specific personalized functions.

These Calculation formulaes can be created via Easergy Builder.

The list of operations available are given in the Easergy Builder User Manual.
Refer to this document for more information related to the calculation formulae.

1.4.1.8 IEC 61131-3 PLC

An IEC 61131-3 programming tool (IsaGRAF® platform) is available with the T300
for developing PLC programs.
This IsaGRAF® platform is an external software tool to be installed on a PC.
It is used to develop specific custom applications in the following programming
languages:

o SFC: Sequential Function Chart
o FBD: Function Block Diagram
o LD: Ladder Diagram
o ST: Structured Text
o IL: Instruction List

Before developing and using a PLC program in the HU250, the interface must first
be created with IsaGRAF® in Easergy Builder to define the links and the
relationship between these 2 elements and the CoreDB.

Instructions on how to configure the interface with IsaGRAF® in Easergy Builder
are given in the Easergy Builder User Manual. Refer to this document for more
information.

1.4.2 Management of RBAC and security policy

The T300 is provided with a standard security policy and a default RBAC (roles
assigned to a number of predefined users).

The T300 security policy is managed by a special tool - SAT (Security
Administration Tool).
The SAT can be used during the engineering phase to redefine or change the
system access restrictions, including the access rights and responsibilities, via an
RBAC (Role-Based Access Control) model.

Radius protocol provides also the capability to have a generalized and unique
authentication policy on a dedicated server, rather than to define them locally on the
various T300s of the network.

The commissioning phase done in the Web server will be only limited to adding or
deleting users, to modify their associated passwords, and to assign or modify one or
more of the roles pre-defined in the SAT to these users.

See the Managing Users and Roles section for more information on how to set
these parameters.

Instructions on how to configure the security policy in the SAT are given in the SAT
User Manual. Refer to this document for more information.

the available ETH port.

Ethernet cable for the PC-T300 link

2 Connecting to the T300 Web Server

Easergy T300 needs a connection from a PC, tablet, or smartphone to
be able to configure, consult, or carry out maintenance on the equipment:
This can be via a WI-FI or Ethernet connection (via the HU250 module).

Equipment Required for the T300 Connection

The T300 needs a PC with Windows XP, 7, or more recent operating system, and a
web browser, such as Internet Explorer (version 10 minimum), Mozilla Firefox, or
Google Chrome. It also needs:
 An Ethernet port (RJ45) on the PC to connect to the T300 via an

Ethernet network or direct PC-T300 access

 WI-FI access on the PC to connect to the T300

Note: The choice of WI-FI or Ethernet access to the T300 is up to the user.
There is no difference in operation between the 2 types of link. However, Wi-Fi is
considered as a Local access mode and Ethernet a remote access mode, with the
possibilities that relate to these two modes.

The T300 parameters and data are accessed directly via a web browser.
No other additional software is required to access the embedded Web server.

Principle of the T300 Embedded Web Server

The T300 includes an embedded server that initializes automatically as soon as
the connection is established with the T300.
The data displayed by the T300 via this embedded server is presented in the
form of HTML pages.
Different pages and subpages can be accessed by the user depending on
their user rights. The HTML pages displaying the data managed by the T300 are
refreshed in real time to help ensure they show the most up-to-date status
information.
Access and connection are secured by a login and password.

From the embedded server you can:

 Modify the fault current detection, communication, automation fucntion, or

system parameters
Note: The T300 is supplied with default parameters that can be modified
as required by the user.

 View the states managed by the T300 (indicators, events, potential issues,

measurements, counters, etc.)

 Save the T300 configuration to file or download it from a file already saved

on the PC

 Send remote control orders to the T300
 Transfer diagnostics logs in .csv file format compatible with Excel
 Load a new version of the T300 application firmware (to the HU250 or the

SC150 and LV150 modules)

IP Addresses for Connection to the T300

As standard, the T300 integrates IP addresses for the local Ethernet connection
from a PC as well as for WI-FI access. The following characteristics are needed
to establish these connections:

 Default T300 Ethernet port address: https://192.168.0.254
 WI-FI access:

 WI-FI SSID = EasergyT300
 Password = EasergyT300
 WI-FI IP address = https://192.168.2.254

Note: To prevent conflicts and for security purposes, it is advisable to configure a
single and unique SSID for each T300. Refer to the corresponding section in this
manual for information on how to change these parameter settings.
The default connection parameters are general purpose, but it is possible to modify
them to meet your network specifications.

Connecting to the T300 Web Server

Instructions on how to connect to the T300 web server are not given in this manual.
Refer to the T300 Quick Start Guide (reference NT00383-xx), for detailed
instructions on how to connect via Ethernet or WI-FI.

Monitoring & Control / Status page – Web server

3.1.4 Data Pages

Accessed via: Monitoring & Control/Status-Command-Analog-Setpoint page

There are 4 pages in the T300 Web server for viewing status and measurement
data or for sending commands:

 Status page: For viewing the status of the digital data
 Command page: For sending change of state commands based on the

digital data

 Analog page: For viewing measurement values
 Setpoint page: For forcing parameter values

Each page has the same format, with the following information displayed on
the screen:

 The data refresh period can be configured in 1 of 3 ways:

o Fast: Data is refreshed every second
o Normal: Data is refreshed every 4 seconds
o Slow: Data is refreshed every 10 seconds

 It is also possible to set a filter to display data by Source or Destination to limit

the amount of data displayed on screen:

 The description of a data item is displayed over 3 main columns:

o Point name  Internal name of the data item in CoreDb (database)
o Description  Data label
o Value  Value of the data item

 By clicking the button associated with the Value field, you can manually

edit the state or value of a Command or Setpoint data item:

Note: For switch control, it is advisable to use the interface in the Substation view.

Example of Analog data display

 Similarly, for a Status or Analog data item, you can force its status or value.

However, this type of data is only processed in read mode; forcing is only
applied in simulation.

To do this, the actual data item must first be locked by clicking the Locking option.

Once the data is locked, the button associated with the Value field then
becomes accessible and can be used to change its status or value in
simulation mode.

Note: The modified value also impacts the remote retransmission at the
SCADA end. This allows you, for instance, to simulate the state of a variable
and to test its retransmission at the SCADA end, without affecting the actual
equipment operation.

Disabling the Locking option cancels the simulation and returns to the actual
status or value of the data item.

 Two icons displayed in the Quality column provide an indication of the data

processing quality. The quality of a data item can give an indication of the
validity of the status or value entered on the Web server page.
This quality is indicated for the following 2 sources:
o Local source: Reflects the quality of the data item from the viewpoint

of its processing at the HU250 end

o Remote source: Reflects the quality of the data item sent by the

information source (device) processing the data (e.g. SC150, PS50, etc.)

NT00378-EN-03

In the same way as for a change of state or value for Status or Analog
it is possible to manually simulate the quality of a data item.
To do this you must first lock the data item using the Locking option,

then click the button associated with the Quality field.
The possible choices for the local and remote source quality are then displayed
on screen.

Disabling the Locking option cancels the simulation and returns to the actual
quality of the data item.

3.2.1 Measurements Pages

Accessed via: MV and LV Measurements/PM-Power/PM-Energy/Power-Quality
page

The MV and LV Measurements pages in the Web server display the different
types of power, energy, and quality measurements taken by the T300 on the MV
and LV networks, in tabs including data tables based on the analog data received
from the current and voltage sensors.
Note: Regarding MV voltage measurement, the T300 takes the measurements
using the same current and voltage sensors as those used to detect fault currents.

The power and energy measurements comply with standard IEC 61557-12.
The power quality measurements are completed according to the principles of IEC
61000-4-30 class S (up to harmonic 15).

Note: To comply with the accuracy required by the standards (1% accuracy),
voltage measurements are only possible using LPVT or VT type adaptors (for LV
measurement; only Voltage adaptor type).

Some measurements are optional for the T300 ("option" column in the table
below). If the corresponding option is not present in the equipment, the associated
data is not displayed in the LV and MV Measurements pages.

Note: The PM option (and associated measurements) is included as standard for
LV measurements, although this is optional for MV measurements.

The data displayed in the MV Measurements page depends on the parameter
settings in the Settings/SC0x/Measurements and Power Quality pages.
The data displayed in the LV Measurements page depends on the parameter
settings in the Settings/LV0x/Measurements and Power Quality pages.
Refer to the corresponding sections for more information on how to configure
these parameters.

The list of measurements displayed in the MV and LV Measurements pages is
