T300 configuration steps

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:

1.4.1.1Adding/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.

1.4.1.2T300 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.

General description

1.4.1.3Sequence 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.

1.4.1.4The 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.

1.4.1.5Personalization 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.

It is possible to customize the colors of the LEDs and set the I/O filter parameters via the Web server (see the Local I/O section).

Note that the same operations can also be carried out in Easergy Builder.

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

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.

1.4.1.7Calculation 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.

1.4.1.8IEC 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.

Connecting to the T300 Overview of the T300 Web Server

Connection of a configuration/consultation/maintenance PC to one of the available ETH port.

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.

Power supply shutdown

A power supply shutdown occurs when the mains power supply has been switched off for a long time, in order to limit the time on the backup power supply (battery). This power interruption preserves the capacity of the battery and its lifetime. Battery backup saving can be enabled or disabled by configuration.

When this function is enabled, as soon as the MV network is switched off, the battery takes over the power supply for a configurable maximum period Backup time duration (default: 16 hours).

Beyond this period, an immediate alarm General shutdown is activated and then Power supply is switched off automatically. The power supply is also switched off if the battery reachs low level and then PS50 module enters sleep mode until the AC network voltage returns.

From this sleep mode, the 24/48 V & 12 V power supply outputs can be reactivated temporarily when the PS50 module is reset (Reset button ) or when the External Reset digital input of the PS50 module is activated. The power supply is switched off again and permanently if it reach the critical discharge threshold (< 10.8 V).

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.

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.

Example of Analog data display

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.)

In the same way as for a change of state or value for Status or Analog data, 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.

The table below shows the correspondence of the different quality types that can be simulated after having locked a data item.

Note that this also gives an indication of the different quality types that can be obtained in actual operation:

	Local source quality	Description
	Overflow	An overflow has occurred on a counter
	Rollover	An overflow and an automatic reset have
		occurred on a counter
	Counter adjustment	The counter has been adjusted
	Chatter	Excessive change on a digital input
	Locked	The data item is locked
	Manual	The data item has been manually replaced
	Not typical	The data item has not yet been written to
		the database
	Invalid data	Data item is invalid
	Critical alarm	The value of the data item has exceeded
		the High-High alarm threshold
	High level alarm	The value of the data item has exceeded
		the High alarm threshold
	Low level alarm	The value of the data item is below the Low
		alarm threshold
	Signal alarm	The value of the data item is below the
Choice of quality options for the local and remote sources		Low-Low alarm threshold
	Invalid time	The data item time-stamp is invalid or
		inaccurate (the HU250 is not synchronized
		by a source)
	Remote source quality	Description

3.2 Measurements

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 identical and shown below:
