The so-called conventionalelectrical installationrequires not only
• supply lines for powertransmission,
but also a separate line orwire• for every switching
command,• or every measurement,• for every message,• for every controller or
regulator.
All lines which are
not required for
power transmission are
replaced by a bus line in
the ABB i-bus® EIB.
!
The following illustrationmakes this clear:
• The bus line is connectedto an EIB power supplyand all the other stations.
• The 230 V line (or the400 V line) is not requiredfor the control stations
(sensors). It is onlyrequired for the powersupply to the consumers.
• As a consequence, thereare 2 supply systems; onefor power transmissionand one for informationtransmission.

2. EIB System Overview
2.1 General
2.1 General
The EIB system ope-rates decentrally and
does not require a PC orany other special controlunit after start-up. The“intelligence” or rather theprogrammed functions arestored in the stations(STNs) themselves.
!
Each STN can exchangeinformation with any otherSTN by means oftelegrams.
The lowest configurationlevel is referred to as a line.A max. of 64 stations canbe used in one line. Theactual number of stationsdepends on the selectedpower supply and thepower consumption of theindividual STNs.
There are four types of device
• System devices:
Power supply, data bus,serial interface (RS-232),connectors, choke, linecouplers and areacouplers
• Sensors:
Pushbuttons,transducers (wind, rain,light, heat, etc.),thermostats, analogueinputs
• Actuators:
Switching actuators,dimming actuators,actuators for blinds,heating actuators
• Controllers:
Sensors and actuatorscan be logically connec-ted together by meansof controllers (logicunit, logic module orsimilar) for morecomplex functions.
2 STNs can collaboratewith a power supply via thebus line in the smallestconfiguration. The installa-tion bus progressivelyadapts itself to the size ofthe system and therequired functions and canbe extended to more than45,000 STNs.

2.2 Typical distribution
structure for one line
Description of the device:
1. Residual-current-operat-ed circuit breaker forsub-distribution board
2. Miniature circuit-breakers; reserve one forthe EIB and the servicesocket
3. Socket for service work,e.g. for a lap-top
4. EIB power supply5. Double connector (contact
to the data bus)6. RS-232 on the data bus for
service work with the PC7. Filler panel. The data bus
can be seen inserted inthe top-hat rail
Explanatory notes about
the structure:
• There are 2 different sizedpower supplies, 320 mAand 640 mA. In cases ofdoubt, select the largerpower supply with 640mA, because some EIBstations consume doubleor several times thecurrent. Connection ismade to the low voltagemains supply (L, N, PE)and to the bus line (24 V).
• All the STNs associatedwith the line and thepower supply areconnected via this busline.
For service purposes,it is good policy to
install a PC interface (RS-232) and a REG socket per-manently in thesub-distribution board. Thebus line of the PC interfacemust be connected via adata bus inserted in the top-hat rail. The data bus is typi-cally connected to the busline by means of a doubleconnector, which is alsosnapped on to the top-hatrail.

• The bus line is led to theremaining stations. Werecommend using anEIB-certified bus line. Inaddition to the requisitephysical properties(number of cores,
cross-section, isolationvoltage, etc.), the bus linecan be immediately distin-guished from other weak-current lines.
2.3 Line topology
The bus line of the EIB canbe laid in almost any man-ner. The line topologies line,star and tree can be com-
bined. Only rings may not beused. The EIB does not
require a terminating resis-
tor.
The maximum line lengths within a line may not beexceeded, however.!
Power supply to the last station (TLN) max. 350 m
From the first STN to the last STN max. 700 m

2.4 Distribution structure
for several lines
If there are more than 64STNs, or several parts ofthe building are involved,with the result that it isnecessary to bring in atleast a second line, the
lines are connectedtogether by means of a linecoupler. The so-called mainline, which also requires apower supply, forms thebackbone of the line cou-plers.

3. EIB Cost estimation
3.1 General
3.2 Cost estimation in the preplanning stage
3.3 Cost estimation in the execution planning stage
3.1 General
Simplified cost estimationmethods can be applieddepending on theseconstruction stages:
• preplanning• execution planning
The objective is to portraythe functionality in relationto cost. The proposedmodels naturally can notprovide exact results thatcould be used in one form
or another in the finalcalculations.Instead, the models illustrate the ability to esti-mate cost in comparisonwith conventional techno-logy or other systems.Experience in the field hasdemonstrated that thecosts for EIB in functionalbuildings generally are nothigher that those of analternative solution, since,even in buildings of lower
• In functional buildings,it is generally possibleduring the preplanningphase to start at costneutrality, even if thecosts are estimated flatrate and based onsquare-metres area.
• For private properties,the implementation ofEIB makes financialsense only if there areincreasedrequirements.
standards, the functionshave a certain demand forautomation.For private properties, thisis usually not the case,which explains the additio-nal cost. In such cases, theend customer has to makea decision by weighing theresulting advantages.
3.2 Cost estimation in the
preplanning stage
In terms of the electricalinstallation, preplanningsimply entails estimatingthe total costs based on theprototype of the building tobe constructed.In doing so, a three-level,flat-rate sum based on thesquare-metre area of thebuilding is often used toachieve this estimate. Theso-called low, middle andraised standards used inthis estimation generallydo not specify details withregard to the individualassembly groups or theirfunctions. This estimatecan be described from the
perspective of the construc-tor or investor as more orless a rough quote of thecosts based on the size ofthe building and the level ofthe equipment.Independent of the executi-on level, it can be said fornon-residential buildingsthat the cost of imple-menting EIB does not differfrom that of alternativesolutions if EIB is to beused for automation tasksonly. In the case of a lowerstandard, this can of coursemean, for example, thatonly a few central faultmessages or timed switchfunctions can be taken on.Nevertheless, even suchlimited implementations
have proved useful, asunforeseeable changes tothe requirements profileare made continuouslythroughout the construc-tion phase. The adaptabilityof the EIB is, especially inthis case, a great advan-tage.For private properties,the implementation isworthwhile only if thereare increased require-ments on the electricalinstallation. This forexample could be theimplementation of electricblinds or a high-qualitylighting control systemwith light scenes.
3.3 Cost estimation in the
execution planning stage
During the executionplanning stage, the planner(generally the installer forprivate properties) determi-nes the functionality of theelectrical installation in co-operation with the client orthe client's agent inde-
pendent of the system tobe used. The expected costs arethen determined based onthe functional descriptiondetermined by the plannerand client. Those who arenew to EIB frequently findit especially difficult to esti-mate the costs. A frequentmistake is to base the
estimate on individualdevices, which, withoutdetailed context, oftenappear "too expensive." However, it is possible tocome to an estimation thatis quite accurate withoutgreat effort.The cost estimatepresented here is based onflat rates which have beencalculated according to listprices in the € zone.
The estimate is calculatedin four steps.• Determining the costs of
active devices• Determining the costs of
system devices includingaccessories
• Determining the costs ofprogramming andcommissioning
• Determining costs forspecial items

An example:
This example is intendedto clarify the process ofcost estimation. A newschool is to be built.A meeting betweenbuilders and buildingplanners results in thefollowing requirementsprofile, which includesthe implementation ofEIB.
3. EIB Cost estimation
3.3 Cost estimation in the execution planning stage
1. Determining costs for active devices
Active devices are all actuators andsensors that are part of the EIB. Insteadof calculating the actual, concrete devicethat is to be implemented, flat rates thatare based on specific functions are usedin estimating the costs.• Switched loads . . . . . . . . . . . . . . 120 €• Dimmed loads . . . . . . . . . . . . . . . 220 €• Groups of blinds . . . . . . . . . . . . . 180 €• Heating circuit
with continuously regulated valves 400 €with electro-thermal valves . . . . 260 €
• Message monitoring . . . . . . . . . . . 60 €
2. Determining costs for
system devices
With the presumption that the individualEIB line is equipped with about 50devices, and while assuming a meanprice for active devices, it is possible toassess the costs of the system devices aswell.Costs of system devices =
7% of the cost of active devices
3. Determining the service cost
Based on experience and using flat rates,it is possible to estimate the costs forprogramming and commissioning.• Programming 10% of the cost of active
devices• Commissioning 5% of the cost of active
devicesImportant: The programming canrequire significantly more time in
private houses because each room can beassigned its own individual functions.Simply copying functions from room toroom, as is often possible in commercialprojects, frequently can not be done. Incases of complex application, programmingcosts of up to 20% of the cost of activedevices can be reckoned with.
4. Special costs
Special costs include those which can notestimated on a flat-rate basis.

4.2 Installation sheets
4.1 General
Planning with EIB differslittle from planning basedon conventional tech-niques. There are twodifferences, however,which the planner needsto consider.
1.The specification (bid)should include a detailedfunctional description, asthe functionality generallycan not be determinedfrom the bid devices.This functional descrip-tion allows the tenderingcompany (usually theinstaller) to estimate theinput required for pro-gramming the buildingbeing constructed.
2.The layout of the EIBshould be illustrated in adiagram. This providesadditional information ontime and cost require-ments and illustratesthe planned structureof the project. (Refer to "Topology".)
4.2 Installation sheets
Like planning using con-ventional technology, theinstallation plan providesinformation on the spacialpositioning of the instal-lation devices, the function

is not included in the plan-ning. Instead, this service isprovided by the companycarrying out the installationor by a specialised serviceprovider.
Recommendations forplanning with EIB:Field experience has shownthat the less experiencedtend to offer the EIB as aseparate item. This leadsto the following disadvan-tages:
• Only with difficulty canthe tendering installermake correlationsbetween the variousassembly groups.
• The constructor gets theimpression that the EIB isan optional item that canbe removed from the bid.This of course is the caseonly if an alternativesystem is implemented(which often requires fur-ther measures) or if theparties renounce agreedsolutions.
This can be avoided byintegrating the plannedimplementation into thestandard segmentation ofthe specification (e.g. light-ing, heating...) bid.
can not be mirrored in theplan because the functionis ultimately determinedwhen the devices areprogrammed, not whenthey are installed.

5.1 The European Tool
Software (ETS)
The ETS is the standardsoftware used for commis-sioning the EIB. Unlikeother systems, all manufac-turers of EIB products usethe ETS to commissiontheir devices. This guaran-tees product compatibilitybetween different manufac-turers. The product datacan be obtained from themanufacturers free ofcharge. The product data
can be imported into theETS by the user without aproblem.The ETS is not free ofcharge and can be pur-chased through the EIBA:www.eiba.com/index.html
Training programmes areoffered in many countriesthrough certified trainingestablishments. For moreinformation on training,please ask your representa-tive.

5.2 The programming
process
Programming the systemin the ETS requires severalsteps.
Create the building structure (optionally)
Building, storeys and rooms/distributorsof the project are defined in the form ofa tree structure.
Create the devices of the project
The devices required are added into therooms/distributors and their parametersare defined. Unique "physical addresses"are assigned to the devices (see diagramon the right)
Define the functions in the project
Each function is given a name, whichserves as the so-called group address (see diagram on the right)
Create the interconnections
Devices are linked via the group addresses,which is comparable to the layout andconnection of control lines in theconventional technology.
21
There are twofundamentally differentaddressings:• Physical address• Group address
Physical address
The physical address actslike a telephone numberfor each individual station.As a consequence, eachphysical address occursonly once in an EIB pro-ject. On the basis of phy-sical address, you can also recognize in which line the STN is located.
Area 1Line 4 1.4.5Station 5 }Group address
The group address alsoserves as a numbering forthe individual functions. Agroup address occurs in aproject at least twice, oncefor the sensor and once forthe actuator. The sensorand actuator are functional-ly connected by their beingassigned with the samegroup address. The groupaddress sent by the sensoris heard by the actuator,
and the correspondingswitching operation iscarried out.Division into main and sub-groups has become normalpolicy. From ETS 2, there isa second method of repre-

Addressing on two levels Addressing on three levels

5.3 The commissioning
process
To commission the system,the programmer's localcomputer has to be con-nected to the EIB installa-tion. The following optionscan be used to achieve theconnection:
• Serial COM port• USB port (with ETS3
and later)• LAN/ISDN gateway
(remote maintenance)
Once one of these connec-tions has been established,the next step is to load thephysical addresses into thedevice. This requires pressinga programming button on thedevice once.After this is done, the so-called applications (whichcomprise the actual deviceprogram) can be loaded. Thistakes place via the bus, with-out having to access thedevice manually.
Laptop
Interface RS 232 or USB
1. Do not plan with more than 40 to 45 stations (STNs)per line when using the Busch EIB Installation Bus,so that a second line is not immediately required inthe case of extension.
2. Adapt the bus structure to the building, e.g. one lineto each floor. This increases the transparency of theproject.
3. A certified bus line has two core pairs. The first corepair (black and red) is required straight away. Thesecond one can be subsequently used for anotherpurpose, as required. It is therefore good policy towire up this second core pair in each branching box,etc, as well.
4. We recommended providing several programmingfacilities in larger Busch EIB Installation Bus installa-tions. This means providing a serial interface (for thebus connection) and a socket (e.g. for a lap-top) atseveral locations.
5. Use a certified bus line. This has the requisite physi-cal properties (number of cores, cross-section, isola-tion voltage) and can also be easily distinguishedfrom other weak-current lines. Possible cable typesare: JY(ST)Y 2x2x0.8 or PYCYM 2x2x0.8.
6. In principle, there are two ways of arranging theactuators in a building; decentralized in suspendedceilings or centralized in sub-distribution boards.Both possibilities have their advantages:
decentralized
• less installation work• fewer lines and, as a result, lower fire load and
smaller cableways• smaller sub-distribution boards
centralized
• the devices are more easily accessible• the devices are clearly arranged
