Introduction

Overview

The EIFE embedded Ethernet interface for one MasterPacT ™ MTZ drawout circuit breaker (or EIFE interface) enables one MasterPacT MTZ drawout circuit breaker to be connected to an Ethernet network.

It provides digital access to all the data delivered by the MicroLogic™ X control unit of the MasterPacT MTZ circuit breaker. It provides information about the Intelligent Modular Unit (IMU) system. In addition, it monitors the three positions of the circuit breaker when inserted in its cradle:

• Cradle connected

• Cradle disconnected

• Cradle test positionS

EIFE Interface Features

The main features of EIFE interface are:

• Dual 10/100 Mbps Ethernet port for simple daisy chain connection

• Device profile web service for discovery of the EIFE interface on the local area network (LAN)

• Ethernet interface for MasterPacT MTZ drawout circuit breakers

• Embedded settings webpages

• Embedded monitoring and control webpages

• Embedded diagnostics webpages

• Embedded security webpages

• Cradle status management (CE, CD, and CT)

• Built-in email alarm notification

• IEC 61850 interface for MasterPacT MTZ drawout circuit breakers

• Machine-to-Machine (M2M) communication

• Role-Based Access Control (RBAC) for users accessing the webpages

EIFE Webpage Sessions

Maximum of 8 HTTP sessions are supported. Once the HTTPS is enabled, only 4 HTTPS sessions are supported at the same time.

EIFE Firmware Versions

This guide describes the webpages for two different firmware versions of EIFE interface:

• EIFE Interface Webpages from Firmware Version 005, describes the EIFE interface webpages for the firmware version 005 and later.

• EIFE Interface Webpages up to Firmware Version 003, describes the EIFE interface webpages for the firmware versions up to 003.

EIFE Interface Supported Protocols

The EIFE interface supports the following Ethernet protocols:

• Modbus TCP/IP: Modbus TCP/IP is a protocol, which provides client/server communication between devices and Modbus TCP/IP that provides communications over an Ethernet connection. Modbus TCP/IP is used to exchange data between EIFE interface and other compatible Modbus TCP/IP devices through TCP port 502.

• Secure Modbus TCP/IP: Is a secure protocol, which provides client/server communication between devices and TCP/IP that provides communications over an Ethernet connection. Secure Modbus TCP/IP is used to exchange data between EIFE interface and other compatible Modbus TCP/IP devices through TCP port configured by user through IFE webpage. By default this protocol will be disabled.

• Hypertext Transfer Protocol (HTTP): HTTP is a network protocol that handles delivery of files and data on the World Wide Web. It provides web server functionality through TCP port 80. Remote configuration of EIFE interface and viewing of diagnostic data is possible using a web browser.

• Hypertext Transfer Protocol Secure (HTTPS): HTTPS is a variant of the standard web transfer protocol (HTTP) that adds a layer of security on the data in transit through a Transport Layer Security (TLS) protocol connection. HTTPS enables encrypted communication and secure connection between a remote user and the EIFE interface. It provides web server functionality through TCP port 443.

• File Transfer Protocol (FTPS): FTPS is a variant of the standard File Transfer Protocol (FTP) that adds a layer of security on the data in transit through a TLS protocol connection. FTPS enables encrypted communication and secure connection between a remote user and the EIFE interface.

  NOTE: For EIFE interface with firmware version 004.006.000 and later, use a FTPS client, such as FileZilla or WinSCP to transfer the IEC 61850 configuration files.

• Simple Network Management Protocol (SNMP):Based on MIB2 format, SNMP provides the ability to store and send identifying and diagnostic information used for network management purposes through UDP port 161.

• Rapid Spanning Tree Protocol (RSTP EcoStruxure Power Commission Software): RSTP is a network protocol that ensures a loop-free topology for Ethernet networks. It is the advanced version of Spanning Tree Protocol, is a link layer protocol executed within bridges or switches.

• Devices Profile for Web Services (DPWS): DPWS defines a minimal set of implementation constraints to enable secure web service messaging, discovery, description, and eventing on resource-constrained devices.

• Network Time Protocol (NTP): NTP is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks.

• IEC 61850 Protocol: IEC 61850 is a standard for communication networks and systems in substations. Based on Ethernet protocol, it is a standardized method of communication developed to support integrated systems, composed of multi-vendor, self-describing Intelligent Electronic Devices (IEDs). These systems are networked together to perform real-time protection, control, measurement, and monitoring functions.
