Which functions can ABB i-bus® EIB be used for?

Lighting
The lighting can be manually switched or dimmed. A switch sensor can operate any lamp in the house or external lighting. All the lamps can be switched off centrally (before going to bed or when leaving the house) or switched on (e.g. to warn away intruders). Lightscenes that are used frequently (e.g. for reading, watching TV or at mealtimes) can be stored by pressing a button and recalled again as often as necessary with a single push button action. Infrared remote control enables the operation of selected functions, without you having to leave your seat. All the lighting functions can be automatically run using time programs or triggered via a motion sensor which detects the presence of people in the building. Constant lighting control is particularly suitable for office workstations where the brightness level at the workplace must be kept at a previously specified value, regardless of whether the sun is shining or the sky clouds over. In functional buildings, several users can make very different demands on the lighting system: the employees require a pleasant lighting level for working; the lighting is alternately dimmed up and down during meetings and presentations; the cleaners might need all the rooms to be lit up at the same time and the owner requires any unnecessary lights to be switched off or dimmed down in order to save energy costs. ABB i-bus® EIB gives you the flexibility to do this.

Temperatur Control

ABB i-bus® EIB can also be implemented for individual room temperature regulation. The temperature is constantly measured and adjusted to the required level via the radiator valves controlled over EIB. Such valves can also be closed automatically when windows in the room are opened (via window contacts) to avoid wasting energy. A pleasant temperature is thus achieved in each room (individual room control). The required temperature can be set using the rotary thermostat control or by pressing a push button. The temperature variation over the course of the day can be automatically programmed dependent on the room usage. During the night, the temperatures in selected rooms can be lowered to save resources and thus help to preserve our environment. Shading Shutters and roller blinds can be individually raised and lowered: either fully, step-by-step or moved to a specific position. All the shutters and roller blinds can also be moved simultaneously – all rooms can thus be made darker or lighter at the touch of a button. Manual shutter control functions can also be carried out via infrared remote control. The shutter control functions can be carried out fully automatically using a control system with time programs, light sensors or wind sensors. All the roller blinds, for example, can be closed if the brightness level drops below a specific value after 18:00 or they can be closed during the day for protection against intense sunlight.

Security
With ABB i-bus® EIB, important security functions can be integrated into the electrical installation.
Presence simulation: During your absence, the roller blinds open and close at the usual time, the lights are switched on and off and the radio plays music every now and again. It therefore does not occur to anyone that you are not at home.
Lock monitoring: Contacts check whether all the doors and windows are closed. A warning signal can therefore be sounded, for example, before you leave the house if any doors or windows are open. Skylights and garage doors can also be monitored in this way.
Intruder: Alarm signals are triggered if doors and windows are forcibly opened or broken. The presence of unauthorized people inside the house can be recorded with motion detectors. If you are in the house and feel threatened, you can trigger an alarm via an emergency call button.
Alarm signals: In the case of an alarm, a local alarm can be sounded via sirens and strobe lights or a silent alarm can be triggered and a telephone dialing device activated. The silent alarm can notify you either directly via the telephone, inform a neighbor or an emergency service centre.
Fire: Smoke detectors can also be integrated into the electrical installation. All the occupants of the house are thus reliably warned about the possible danger. Additionally a security company can be alerted in good time, before the house is engulfed by flames.
Technical alarms: ABB i-bus® EIB also manages technical signals. You can therefore protect the property against serious damage if water seeps in or there are technical faults in the electrical installation.

All alarm reports can be shown on a display or panel unit. In this way, you can easily find out which alarm has been triggered and in which part of the building.

Display and operate
ABB i-bus® EIB offers a variety of display and operating possibilities whether you are a home owner, office worker or just a user of such an installation. The clear depiction of information and ease of operation simplify the control of processes in buildings.
Switching states, fault signals and measured values as well as alarm signals can be displayed at various locations inside the building and also externally via the Internet or telephone.
You can switch loads manually via the push buttons on the display unit and carry out your own settings.
PC visualization is particularly recommended for more sophisticated requirements. The PC is directly connected to the electrical installation. The PC visualization enables a very clear representation with numerous individual setting options. LCD displays are particularly suitable for an individual and flexible layout. Text and switch functions can be freely programmed on the PC and loaded into the LCD display via an interface. Switching states or fault signals can also be
displayed via LEDs. Panel units with plan drawings and LEDs, or panels with touch control and LEDs are used most frequently.

Control and logging
Control: Additional functions are made possible in an electrical installation by higher-order control procedures. The effort involved is reduced and the economic efficiency of the installation is increased. Complex logic operations, gates, timing elements and staircase lighting functions can also be easily programmed and integrated into the ABB i-bus® EIB systems.
Logging: The logging of important switching commands and fault signals increases the transparency of an installation. The availability is thereby improved, the checking process is simplified and the functional reliability as a whole is increased. ABB i-bus® EIB can print out the log of selected events with any required textual information on one or several logging printers.

Ventilation
Ventilation makes a significant contribution to achieving a pleasant atmosphere in rooms. You can open and close skylights or glass façades using ABB i-bus® EIB. A weather station ensures that the onset of rain is detected and the windows are automatically closed to prevent any water from getting in.

EIB Devices and Stations

EIB terdiri dari beberapa Device / peralatan, dimana semua peralatan ini mempunyai fungsi masing2. Pada dasarnya Peralatan EIB ini terdiri dari 4 jenis, yaitu :

1. System Devices

Yaitu : Power Supply, Comunication data devices (RS 232 atw USB comunicator), Line Coupler dan Area Coupler. Device ini tidak di hitung sebagai 'Station'.

2. Sensors Devices

Yaitu : Push Button (Saklar) dengan type yang macemnya banyak sekalee, tranducer (untuk sensor angin, hujan, panas, cahaya, dll), thermostat, analog input. Device ini masuk kategori 'station'.

3. Actuators Devices

Yaitu : Lighting Actuator (berfungsi sebagai pengganti fungsi saklar), dimming actuator, blind actuator dan heating actuator. Device ini masuk juga sebagai kategori 'station'.

4. Controllers Devices
Sensor dan Actuator bisa di gabung dengan peralatan logic yang cukup komplex. Device ini juga masuk sebagai kategori 'station'.

Penjelasan di atas merupakan penjelasan secara umum, bila ada yang membutuhkan katalog dari devices diatas saya bisa kirimkan via email. Tapi saya hanya punya katalog ABB, sedangkan merk2 EIB lainnya silahkan minta ke distributor terdekat.

Sebagai informasi tambahan, jumlah peralatan EIB yang akan di pasang tergantung dari banyak faktor, biasanya semua informasi tersebut di dapat dari konsultan dan owner. Intinya semua tergantung dari keinginan pemilik, sampai sejauh mana beliau ingin mengkontrol peralatan rumahnya. Supaya kesannya tidak terlalu rumit, saya coba jabarkan informasi yang biasanya saya butuhkan secara umum :

1. Gambar perencanaan Listrik, gambar layout dan single line diagram dari bangunan tersebut.
2. Informasi dari Pemilik atau konsultan, apa saja yang ingin dikontrol oleh EIB. Yang pasti di kontrol adalah penerangan, namun sebenarnya tidak perlu seluruh penerangan dikontrol karena akan mubazir. Contohnya ruang service, ruang pembantu / sopir cukup menggunakan system konventional saja.
3. Khusus untuk Penerangan, jenis lampu dari penerangan yang di kontrol harus diketahui ( TL, Pijar, Halogen dll ). Kemudian lampu mana saja yang di kontrol oleh dimmer. Masalah ini biasanya cukup sulit ditentukan dari awal, karena berkaitan dengan interior design seperti furniture, warna cat dll.
4. Untuk peralatan mekanikal seperti AC, Motorized Blind, Heater, dll data yang diperlukan selain jumlah dan bebannya diperlukan juga Merk dan input / output yang di butuhkan (binary atw analog)
5. Karena EIB system mempunyai Security Module, maka dimungkinkan EIB system mengkontrol Security systeam dalam satu kesatuan. Bila diinginkan maka diperlukan survey yang lebih mendalam untuk menentukan sensor yang digunakan.
6. Yang terakhir adalah, menentukan jenis device untuk mengkontrol, bisa berupa saklar/push button dan touch screen atau sensor seperti IR dan juga kebutuhan remote kontrol. Pernah ada yang minta di design rumahnya tanpa saklar (swichless), semua penerangan di atur secara otomatis dengan sensor, timer dan IR remote kontrol.

Semua design memang benar2 customized, walau biasanya pada awalnya si pemilik rumah belum bisa membayangkan system yang di inginkan, ketika sytem sudah terpasang baru dia akan merasa mana sebenarnya yang dibutuhkan. Hal ini yang akhirnya menimbulkan kerja tambah kurang. Lain halnya dengan design untuk gedung yang biasanya sudah di rancang dari awal pembangunannya.

EIB Description

Disini saya ingin bahas lebih detail tentang EIB System.

EIB System membutuhkan Power Supply 24Vdc untuk daya sekaligus untuk komunikasi datanya melalui Busline (dalam hal ini menggunakan Kabel Data 2 pair). Setiap Power Supply membutuhkan 220Vac sebagai catu utamanya.

Jadi ada 2 sumber daya dalam 1 installasi, yang pertama adalah 220Vac(1 phase) atau 400Vac(3 phase) sebagai catu utama ke Power supply dan ke setiap beban (seperti lampu, ac dan lain2); dan yang kedua 24Vdc yang dihasilkan oleh Power Supply sekaligus sebagai penghantar komunikasi datanya.

EIB adalah system yang tidak tersentral (decentrallize), artinya EIB tidak membutuhkan panel kontrol sebagai sentral, juga tidak membutuhkan Komputer (PC) khusus untuk data tansfer dan penyimpananya. Seluruh data konfigurasi di simpan di setiap device / station (STN). Setiap STN juga bisa saling berkomunikasi melalui jalur data (telegrams).

Peringkat terkecil dalam installasi EIB kita sebut sebagai LINE. Setiap LINE membutuhkan 1 power supply yang hanya untuk maximum 64 station (STN). Dan Setiap Power Supply bisa berkolaborasi dengan Power Supply lainnya menjadi satu system dan bisa menanggung lebih dari 45,000 station (STN).

Mengingat banyak nya 'Station' yang bisa di gabungkan dalam system ini maka jarak kabel data juga harus diperhitungkan. berikut tabel jarak kabel data :

Berikut juga gambar diagram dari sebuah LINE :

Lalu bagaimana jika sebuah gedung membutuhkan lebih dari 64 station? maka kita bisa membuat LINE kedua, untuk membedakan satu LINE dengan LINE yang lainnya di butuhkan sebuah alat yang bernama Line Coupler. Line Coupler ini juga memerlukan sebuah power supply juga (jadi untuk 2 LINE membutuhkan 2 line Coupler dan 3 power supply), Busline dari tiap line coupler adalah sebagai Main Line alias Back bone system ini. Maximum Setiap 1 Main Line bisa menampung 12 LINE. Biar ga puyeng, lihat gambaran diagramnya sebagai berikut:

Setiap Main Line bisa di gabung lagi menjadi AREA LINE, setiap AREA LINE bisa menampung maximum 15 Main Line. Supaya lebih mudah ngitungnya lihat tabel berikut :

Jadi untuk satu system bisa menampung 11,520 station, sedangkan bila diperlukan installasi yang lebih besar, maka system ini di extended dengan maximum setiap LINE menampung 255 station, total 45,900 Station.... Masih kurang? masa seh?...

Puyeng? sama donk... saya sendiri belum pernah menangani proyek sampai sebanyak itu. Proyek yang pernah saya tangani stationnya tidak lebih dari 64 station.

Dari tadi kita bicarakan Station (STN).. mahluk apaan sih ini? saya akan bahas dalam postingan selanjutnya. Ciao..

A Simple Line Diagram for EIB System

Knowing EIB System

Intelligent installation systems
EIB is the intelligent building installation system that meets the highest standards, being both future-orientated and highly flexible. EIB provides increased security, economic efficiency, convenience and flexibility, whether in office buildings, industrial plants or residential properties. Functions such as lighting, shutter control and heating can be individually adapted to the requirements of the user. Later changes can be easily implemented.

Switching and control – wherever you are
With EIB, you can carry out all the required functions from any location in the building. It is also possible to operate the installation remoterly, for example via a mobile or the Internet. If several functions are to be executed using a single command, this can be implemented without problem. With central commands and user-defined procedures, all the shutters can, for example, be raised simultaneously, the constant lighting control activated and each room regulated to a separate temperature; all with a single push button action.

Automation required?
In building installations using EIB, functions are not only executed via direct manual operation. Using “closed-loop” control systems, the user can preselect an individual daily profile for the room temperature or the room lighting level can be constantly regulated to a required value. Time programs are recommended for regularly recurring events. Shutters and blinds can be raised automatically should the wind become too strong. ABB i-bus® EIB monitors the building and can isolate, for example, electrical circuits in the event of a fire or monitor the energy consumption.

Security around the building
With EIB, professional security functions can be integrated into the building installation. A security control panel manages all security-related signals and triggers alarms. The security control panel can also be conveniently operated via EIB. Signals can be displayed at any location or printed out via a logging printer.

You are kept informed…
EIB makes it possible for current information about the building installation to be displayed continually. You can see at a glance in which rooms the lights are switched on or which doors and windows are open. Measured values can be shown on a display and alarm signals inform you about possible dangers in your building. If someone has forgotten to switch the light off, you can simply switch it off from the display terminal, without even having to walk up the stairs.

Changes implemented in a flash
The office has become a conference room? The top floor has been turned into a separate flat? The functions of the building installation need to be modified? Modifications such as these can easily be
implemented with EIB. You simply need to reprogram and the functions are already adapted to the new conditions. From a distance You can monitor your building via the telephone or the Internet. This is the best way to remain constantly informed….

EIB – one system has won through
EIB corresponds to the European system “European Installation Bus” (EIB for short) which in the meantime is being used all over the world. Since the EIBA (European Installation Bus Association) merged with two other European organizations to form the Konnex Association, has become the new standard in building technology.

Basic principle
With EIB, electrical loads are not switched directly in the circuit with switches and push buttons as in conventional electrical installations (see Diagram 1). Commands are sent instead from sensors (e.g. electronic push buttons) on a twin-core data cable and are received by actuators. The actuators then execute these commands, for example by switching the circuit (see Diagram 2).

What does that mean in practice?
Electrical installations with EIB offer the user numerous advantages:

• Electrical loads can be switched independently of the electrical circuit (e.g. the light in the hallway can be operated from the lounge or from elsewhere in the house).
• Electrical loads can be switched by several sensors without complicated two-way circuits or remote-control switches.
• Functional associations between actuators and sensors can be modified at any time and adapted to individual requirements. All the functions can be programmed so that they run automatically. Logic operations can also be created (e.g. if the brightness level drops below a specific value after 18:00, all the shutters are lowered and the light in the hallway is switched on).
• The switching states of electrical loads can be displayed.

Sensors and actuators
Sensors are, e.g. :
push buttons and switches
room thermostats
movement sensors
time switches
binary inputs
zone terminals
current modules
analogue inputs

Actuators are, e.g. :
binary outputs
dimmers
light controllers
shutter actuators
universal concentrators
display units
