Preface

Our goal was to collect data from the Moeller’s IZM Circuit Breaker using the communication module IZM XEM PGE .

We were interested to give the possibility for collecting data using a web address, beside normal connections types like serial and ethernet on lan.

The given assignment was completed by Miron Emanuel, Dascalu Adrian, Horhota Gigi and Florea Radu, students of ATCR Iasi.

IZM circuit-breakersThe IZM offers a circuit-breaker for use in the high rated current range from 630 A. IZM circuit-

accordance with IEC/EN 60204-1 as they are lockable in the OFF position. They can therefore be used as supply disconnection devices. IZM circuit-breakers are built and tested in accordance with IEC/EN 60947.

Depending on the type of equipment to be protected, main application areas can be implemented by different settings of the trip electronics:

System protection, Motor protection,

Transformer protection,

Generator protection.

IZM devices offer different tripping electronics, for applications ranging from simple system protection with overload and short-circuit release to digital releases with a graphical display and the possibility of creating selective networks.

They can be adapted to a wide range of requirements by means of a comprehensive range of mounted accessories such as auxiliary contacts, trip-indicating auxiliary contacts, motor operators or voltage releases, fixed-mounted or withdrawable units.

With their communication-capability, the IZM circuit-breakers open up new possibilities in power distribution. Important information can be passed on, collected and evaluated, also for preventative maintenance. They thus increase the transparency of the system. For example, by enabling rapid intervention in processes, system downtimes can be reduced or even prevented.

The basic selection criteria of an IZM circuit-breaker are:

Max. short-circuit current Ikmax, Rated operational current In,

Ambient temperature,

3 or 4-pole design,

Protective function,

Min. short-circuit current.

Connection Types

Serial Connection (RS 232)

In telecommunications, RS-232 (Recommended Standard 232) is the traditional name for a series of standards for serial binary single-ended data and control signals connecting between a DTE (Data Terminal Equipment) and a DCE (Data Circuit-terminating Equipment). It is commonly

used in computer serial ports. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pin out of connectors. The current version of the standard is TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange, issued in 1997.

An RS-232 port was once a standard feature of a personal computer for connections to modems, printers, mice, data storage, un-interruptible power supplies, and other peripheral devices. However, the limited transmission speed, relatively large voltage swing, and large standard connectors motivated development of the universal serial bus which has displaced RS-232 from most of its peripheral interface roles. Many modern personal computers have no RS-232 ports and must use an external converter to connect to older peripherals. Some RS-232 devices are still found especially in industrial machines or scientific instruments.

Ethernet connection (LAN)

Ethernet is a family of computer networking technologies for local area networks (LANs) commercially introduced in 1980. Standardized in IEEE 802.3, Ethernet has largely replaced competing wired LAN technologies.

Systems communicating over Ethernet divide a stream of data into individual packets called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted.

The standards define several wiring and signaling variants. The original 10BASE5 Ethernet used coaxial cable as a shared medium. Later the coaxial cables were replaced by twisted pair and fiber optic links in conjunction with hubs or switches. Data rates were periodically increased from the original 10 megabits per second, to 100 gigabits per second.

Since its commercial release, Ethernet has retained a good degree of compatibility. Features such as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols.

Ethernet connection (INTERNET)

Many technologies and service plans for Internet access allow customers to connect to the Internet. Consumer use first became popular through dial-up connections in the 20th century. By the 21st century, most products were marketed using the term "broadband".

Serial Connection

In the following images we will show all the steps needed to create a serial connection using a PC and the BDA Module (IZM XEM PGE).

Ethernet Connnection (LAN)

We changed the BDA’s ip class and we used our Router’s gateway.

Ethernet Connection (Internet)

ATCR Router Settings

In the first image we are showing how to configurate a virtual server .

In the second image we let the BDA Module to communicate with dyndns server.

In the last image we configurated the Router to have acces with the dyndns account.

Creating the web address

We made a DDNS account using dyndns.org (free DDNS service)

The first image is showing the creation of the DDNS account

The second image is showing our Router’s Ip and the bound with the web page izmatcriasi.dyndns.org

The last image is showing that we connected to the izm using an internet web page.
