The application program makes a sepa-rate set of parameters and communica-tion objects available for each input.Further parameters or different commu-nication objects are displayed depen-ding on the parameter settings.

Bus voltage recovery

After bus voltage recovery, the interfacedoes not start to send immediately butonly once an adjustable delay has elap-sed.

The initialisation period of 2 s is alreadyincluded in the sending delay.

Limit telegram rate

On the general parameter page, it ispossible to limit the number of tele-grams that are sent over a specific timeperiod. This factor should be noted pri-marily on bus voltage recovery when alarge number of bus devices send theircurrent status simultaneously.

Function of inputs/outputs

The parameter setting “Function of thechannel” defines the operating mode ofthe input. The following functions can beselected:– switch sensor,– switch/dimming sensor,– shutter sensor,– value / forced operation,– scene control,– control of electronic relay

(heating actuator),– LED control,– switching sequence (“latching

relay”),– push button with multiple operation– or pulse counter.Alternatively, it is possible to fully deac-tivate an input with the setting “nofunction”.

Disable

It is possible to disable an input via the1 bit communication object. To do so, atelegram with the value “1” must be re-ceived. A telegram with the value “0”cancels the lock-out. The disable objectis activated for all the input functions,except for the operation of an electronicrelay and LED control.

Switch sensor

If the function of the input is set as aswitch sensor, it is possible to connectconventional push buttons to the inputsof the universal interface. The ETS2program makes at least one 1 bit com-munication object “Input ... - Telegr.switch” available for each switch sensorinput.

If the setting “Distinction between longand short operation” is set to “yes”, theswitch sensor can distinguish betweena short and a long input signal. A furtherobject “Input ... -long - Telegr. switch”can be activated via the parameter“Number of objects for short/long ope-ration” so that it only reacts to long ope-rations.

Both normally closed and normally opencontacts can be connected to the re-spective input. If normally open con-tacts are used for example, the setting“Connected contact type” must be setto “normally open”.

The information that should be sentwhen the push button is pressed is defi-ned separately for each switch object.Either an ON or OFF telegram can betriggered. Alternatively, no reaction cantake place after a push button operati-on.

It is possible to specify the period whichis interpreted as a long operation by theinput. Intervals from 200 ms upwardscan be set. The period comprises abase and a factor.

Period for long operation =Base * Factor

An adjustable debounce time can be setto prevent a bounce at the contacts ofconventional push buttons or switchesfrom having a negative influence. Thedefault setting of 50 ms should normallybe sufficient for conventional push but-tons.

If the switch sensor input should notdistinguish between a short and longoperation, the input sends telegrams tothe object “Input ... - Telegr. switch” afteran operation at the input.

In this case, the object value can besent cyclically. It is possible to send eit-her each object value cyclically on thebus (setting: “always”) or only specificobject values (setting: “if ‘switch’ = ON”or “if ‘switch’ = OFF”).

The reaction at the closing and openingof the input contact can also be defined.For both cases, it is possible to set se-parately whether an ON, OFF orTOGGLE telegram is triggered. Alterna-tively, it is possible to stop the cyclicalsending.

The cyclic interval required for cyclicalsending is composed of a base and afactor.

Cyclic sending interval=Base*Factor

If only one object is activated, it can besent after bus voltage recovery. Howe-ver, the parameter “Transmit object va-lue after bus voltage recovery” is deac-tivated by default.

If there is no distinction between a shortand long operation, the contact bouncecan either be removed via a debouncetime or a minimum operating time. Thedefault setting of 50 ms should also besufficient in this case for standard pushbuttons and switches.

Switch/dimming sensor

If an input is parameterised as a switch/dimming sensor, the ETS2 program dis-plays by default a 1 bit communicationobject “Input ...-short - Telegr. switch”and a 4 bit communication object “Input... - Telegr. dimming”.

Both normally closed and normally opencontacts are connected to the respecti-ve input. If normally open contacts areused for example, the setting “Connec-ted contact type” must be set to “nor-mally open”.

The 1 bit object “Input ...-short - Telegr.switch” can be masked via the parame-ter “Dimming functionality”. the 4 bit ob-ject is then only available for dimming.

This function is advisable e.g. if a seriespush button occupies two inputs of theuniversal interface. The left push buttonshould only be able to switch on and theright push button should only be able todim.

If both objects are displayed (setting:“Dimming and switching”), the type oftelegram that is sent to the 1 bit objectis defined via the parameter “Reactionon short operation”. The parameter “Re-action on long operation” defines whichinformation should be sent to the 4 bitobject after a long operation.

The period which is interpreted as along operation by the input can be setbetween 0.3 s and 10 s.

It is possible to choose between twodimming modes for different applicati-ons. The default setting is “Start-stopdimming”. This means that the com-mand to dim brighter by 100% is sent tothe 4 bit object after a long operation.When the input signal is cancelled, thecommand to stop dimming is sent.

If “Dimming steps” is selected, the pre-set value “Brightness change on everysent telegram” is sent to the 4 bit object.This is repeated cyclically at an adju-stable cyclic interval.

Step dimming is always used if dimmingshould be carried out via several linecouplers in large installations. This en-sures that all the affected dimming ac-tuators can be dimmed exactly to thesame brightness value. In the case of“Start-stop dimming”, a dimming tele-gram can be retained temporarily in thememory of a coupler because there iscurrently bus traffic on the main line.The dimming actuators on the secon-dary line can no longer display thesame brightness value as on the mainline.

The adjustable debounce time preventsthe unwanted contact bounce of con-ventional push buttons or switches fromhaving a negative effect.

Shutter sensor

When using the inputs of the universalinterface as a shutter sensor, the re-spective inputs can be adapted exactlyto the application. It is possible to selecteither a 1 push button operation, a 1switch operation, a 2 push button ope-ration or a 2 switch operation.

During operation as a shutter sensor,the ETS2 program displays two 1 bitcommunication objects: one for movingthe shutter UP/DOWN and one forSTOP/louvre adjustment.

The other two communication objectsenable the shutter actuator to report theupper or lower limit position. If the shut-ter is in the upper limit position, the ob-ject “Upper limit position” has the value“1”. Otherwise the value of the object is“0”. If the shutter is in the lower limit po-sition, the object “Lower limit position”has the value “1”. Otherwise the valueis “0”.

The limit position objects are particular-ly necessary in single push buttonmode. A push button operation normallytriggers either a movement or louvreadjustment command in the oppositedirection. However, if the shutter is loca-ted in the upper limit position, it is notable to move its louvres upwards.

In single push button mode, the shuttersensor normally distinguishes betweena short and a long operation.

Both normally open and normally closedcontacts can be connected to the re-spective input. If normally open con-tacts are used for example, the setting“Connected contact type” is set to “nor-mally open”.



If a long operation should trigger a mo-vement command, the operating functio-nality “1 push button, short = stepping,long = moving” must be selected. Thelouvre adjustment is then always car-ried out in the opposite direction to thelast movement of the blind.

If a short operation should trigger a mo-vement command, the operatingfunctionality “1 push button, short = mo-ving, long = stepping” must be selected.A long operation in this case triggerslouvre adjustment telegrams. These aresent cyclically.

If a blind should be moved in 1 pushbutton or 1 switch operation mode, thereis no distinction between a short and along operation. The movement com-mand in this case is applied for the du-ration of the input signal.

All the 2 push button or 2 switch opera-tion modes enable two inputs of the uni-versal interface to be used as shutterinputs. In the setting “2 push button,standard”, a stop or louvre adjustmenttelegram is triggered after a short ope-ration while a long operation triggers amovement command.

The setting “Reaction on short/longoperation” defines whether the shuttershould be raised or lowered or the lou-vres should be opened or closed.

In the operating functions “2 switch ope-ration, moving (shutter)” and “2 pushbutton, moving (shutter)“, there is nodistinction between a short and a longoperation. A movement command istriggered automatically after each ope-ration and the shutter or blind is stoppedat the end of the operation.

In the setting “2 push button, stepping”,a louvre adjustment telegram is sentafter each operation. The parameter“Reaction on operation” defines whethera “STOP / Lamella UP” or a “STOP /Lamella DOWN” telegram should besent.

The louvre adjustment telegram is re-peated cyclically for the duration of theinput signal. The cyclic interval is speci-fied with the parameter “‘Telegr. STOP/lamella adj.’ is repeated every”. Intervalsbetween 0.3 s and 10 s can be set.

Value / Forced position

When used as a value or forced positi-on sensor, a 1 bit, a 2 bit, a1 byte, a 2 byte or a 4 byte communica-tion object is available for the relevantchannel, depending on the setting.

If the parameter “Distinction betweenlong and short operation” has been setto “yes”, the ETS2 program displays afurther communication object for therespective input. Each communicationobject has its own set of parameters i.e.a 1 byte object can be selected for thefirst object “Value ...” while a 2 byte ob-ject can be chosen for the second “Va-lue ...” object.

The object type that is assigned to therespective communication object isspecified with the parameter “Reactionon ... operation”. Alternatively, the set-ting “no reaction” can be selected.

The setting “2 bit value (forced positi-on)” makes it possible to address ac-tuators that have a positive drivefunction in accordance with EIS 8. Theforced positioning can be activated (ONor OFF) or deactivated.

In the setting “1 byte value”, values bet-ween “0” and “255” can be sent.

If a “2 byte value” is used, it can havethe following three functions: values bet-ween -32.768 and +32.767, values bet-ween 0 and 65.535 or floating point va-lues. Floating point values can be sentbetween -100.00 and +100.00. They canbe received e.g. by EIB room thermo-stats and thus implement a temporarysetpoint adjustment.


If there is no distinction between a shortand long operation, the contact bouncecan either be removed via a debouncetime or a minimum operating time. Thedefault setting of 50 ms should also besufficient in this case for standard pushbuttons and switches.

Scene control

The inputs of the universal interface canalso be used to recall or store a scene(e.g. a lighting scenario).


Depending on the application, it is pos-sible to implement scene control eithervia “5 separate objects” or via an “8 bitscene”.

When implementing scene control viaan “8 bit scene”, the scene numberwhich should be recalled can be setwith the parameter “No. of scene(0...63)”. The ETS2 program displaystwo communication objects in this case:a 1 byte object “Input ... - 8 bit scene”for sending the scene number to an ap-propriate scene module and a 1 bit ob-ject “Input ... - Store scene”. The storingof the current scene can be triggeredvia this object - if it has been defined inthe parameters - by the receipt of thevalues “0” and “1” in succession. A “1”is sent via this object when a scene isstored. It is thus possible e.g. to switchon a confirmation LED.

The input can differentiate between ashort operation signal and a long signal.A short operation can recall a scenewhile a long operation can store a sce-ne.



If the implementation of the scene con-trol is carried out via “5 separate ob-jects”, the “8 bit scene” object is no lon-ger displayed and 5 further 1 bit or 1byte communication objects “Telegr.switch actuator group …” are shown.Switch and/or dimming actuators can beaddressed via these 5 objects.

The ETS2 program makes an additionalparameter available on a separate tabfor each actuator group. The object type(1 bit or 1 byte) is defined with the para-meter “Control of actuator group ... via”.When controlled via a 1 bit object, thepreset value can be “ON” or “OFF”. Inthe case of a 1 byte object, values bet-ween “0” and 255” can be entered.

Control of electronic relay(heating actuator)

If the universal interface is used to ope-rate an electronic relay for heating con-trol, the ETS2 program can display upto 5 communication objects for the re-spective input.

The control is generally carried out via aroom thermostat. Depending on whetherthe room thermostat sends a conti-nuous (1 byte) or switching control va-lue, the respective input can be adaptedaccordingly. The parameter “Control te-legram is received as” is used for thispurpose. The ETS2 program makes a 1bit object “Switch” (setting: “1 bit (PWMor on-off control)”) or a 1 byte object“Control value (PWM)” (setting: “1 byte(continuous)”) available.

When using the 1 bit object, the inter-face follows the signal of the “Switch”object. When implementing the controlvalue via the 1 byte object, the electro-nic relay switches the electrothermalheating actuator via pulse width modu-lation. This means e.g. if the control va-lue is 70%, that the valve opens for 7min. and closes for3 min. over a period of 10 min. (See alsothe graphic on the previous page forcontrolling an electronic relay).

The current switching state of the re-spective channel is sent via the object“Telegr. status/ackn.”. A telegram withthe value “0” means that the valve hasbeen closed while a telegram with thevalue “1” means that the valve hasbeen opened.

Note:With PWM continuous control, this ob-ject is sent after each change at theoutput. The additional telegram shouldbe taken into account, particularly whenthere is a short PWM cyclic period.

The control mode can be adapted to thevarious valve types. The following opti-ons can be set: “normally closed” or“normally open”.

The parameter “PWM cycle time forcontinuous control” defines the total pe-riod for monitoring the control value.(See also top right graphic).

A further 1 bit communication object“Valve purge” can be activated via theparameter “Enable object “Telegr. valvepurge”. The connected valve can beopened via this object without depen-dence on the input state. The centralobject “Telegr. trigger valve purge”which is able to send cyclically on thebus can be used for control.

The “Position of the valve drive on busvoltage recovery” can be adjusted. Asetting between 0% (closed) and 100%(open) can be selected in 10% steps.

If the setting “Enable monitoring of thecontroller, fault message, forced posi-tioning” is set to “yes”, the ETS2 pro-gram displays a further tab for selectingthe monitoring function, the fault signaland forced positioning.

If the monitoring of the controller is ena-bled, the universal interface expects acontrol value to be sent. If no controlvalues are received within a certain mo-nitoring period, the interface develops afault. This means that the “Position ofthe valve drive on failure of the control”adopts the preset value.

The “Cyclic monitoring time of roomthermostat” can be set. It is composedof a base and a factor.

Monitoring time = Base * Factor

If a failure of the room thermostat hasbeen established and the valve is in thefault position, a telegram is sent via the1 bit object “Telegr. fault”. To do so, thefault object must previously be activa-ted via the parameter “Enable object‘Telegr. fault’”.

The valve can be moved to a presetposition via the 1 bit communication ob-ject “Forced positioning”. Forced posi-tioning or the regular valve purge areused during the summer months, sothat deposits cannot build up on the val-ves. The “Valve position during forcedpositioning” can be set between 0%(closed) and 100% (opened).

Please take the order of priority forforced positioning, valve purge, faultoperation and normal control from thesecond graphic in the bottom right-handcorner.

LED control

When using the universal interface forcontrolling LEDs, a maximum of three 1bit communication objects are availablefor each channel. The object “Output ... -LED switching” is used by default toswitch on the connected LED. A tele-gram with the value “1” normally swit-ches the LED on while a telegram withthe value “0” switches it off again. Thebehaviour can be inverted with the pa-rameter “LED is switched ON, if ...”.

With a further object “Output ... - LEDpermanent ON”, the LED can be swit-ched on independently of the object“LED, switching”. This means that assoon as the object “LED permanentON” has the value “1”, the LED is swit-ched on, regardless of the value of theobject “LED, switching”.

If the LED functionality is modified from“switch ON/OFF” to “Flashing”, thecommunication object “Output ... - LED,switching” is replaced by the 1 bit object“Output ... - LED, flashing”. The settingin the parameter “LED flashes, if ...” de-termines whether a connected LEDstarts to flash with an ON or an OFFtelegram.

It is possible to select the period thatthe LED is switched ON or OFF forwhen it flashes. Both periods can be setseparately between 100 ms and60 ms.

It is possible to define a maximum ope-rating time. To do so, the time limit mustbe enabled with the parameter “Timelimit of LED control”. If “yes” is selected,the connected LED only remains swit-ched on after an ON command for theduration of the time limit. This limit ispreset with a base and a factor.

Time limit = Base * Factor

The current status of the LED is sentvia the object “Telegr. status/ackn.”. Theobject is however only activated if theparameter “Transmit status via object‘Telgr. status/ackn.’” has been set to“yes”.

Switching sequence (“latching relay”)

The use of the universal interface as astepping switch (“latching relay”) ena-bles the flexible switching on or off of upto five 1 bit communication objects via asingle input.


The parameter “Number of objects” de-termines the number of objects. Thatmeans e.g. if “3 levels” are selected, theETS2 program displays three 1 bit ob-jects “Input ... - Value ...” for the respec-tive input.

Three different switching sequencescan be set. If “sequentially on/off (onepush button)” is set, the states of theobjects are modified according to thefollowing switching sequence (examplewith 3 levels):

…>000>001>011>111>011>001>…

If “on/off (several push buttons)” is sel-ected, the states of the objects onlychange in one direction when the pushbutton is pressed. It is possible toswitch upwards (increment) or switchdownwards (decrement). For this rea-son, at least two inputs are required forthese switching sequences: one for thefollowing switching sequences (examp-le with 3 levels):

000>001>011>111and the other switch sensor for the re-verse switching sequences (examplewith 3 levels):

111>011>001>000

If “All combinations” is selected, thestates of the objects are modified ac-cording to the following switching se-quences (example with 3 levels):…>000>001>011>010>110>111>101>100>…It is thus guaranteed that the value ofonly one communication object is chan-ged between two switching levels.

The setting “Function on operation”(only activated for several push but-tons) defines whether an input signalswitches one level upwards or one leveldownwards.

The adjustable debounce time preventsthe unwanted contact bounce of con-ventional push buttons or switches fromhaving a negative effect.With the additional 1 bit communicaitonobject “Level increment/decrement”, it ispossible to switch upwards or down-wards via EIB telegrams. An ON tele-gram switches down one level while anOFF telegram switches up one level.

Push button with multiple operation

When used as a “Push button with mul-tiple operation”, the universal interfacecan detect multiple operations at therespective input. These multiple operati-ons are sent to a maximum of four 1 bitcommunication objects.


The ETS2 program makes a large num-ber of objects available depending onthe “Max. number of operations”. Thismeans that if e.g. a “single operation“and a “2-fold operation” should be eva-luated, the setting “2-fold operation”should be selected. The ETS2 programdisplays two objects “Input ... - Telegr.operation ...-fold”.

The setting “Transmitted value (object‘Telegr. operation ...-fold’)” determineswhich value is sent after an operation(single, 2-fold, 3-fold or 4-fold). Thetransmitted value can be an ON, OFFor TOGGLE telegram.

The parameter “Transmit value on everyoperation” defines whether the interfaceevaluates the respective operationscompletely or confirms them individually.

Example:The “Max. number of operations” hasbeen defined as “3-fold operation”. Theparameter “Transmit value on everyoperation” is set to “no”. In this setting,the interface sends a telegram to theobject “Telegr. operation 1-fold” when asingle operation has been detected. Af-ter a 2-fold operation, a telegram is sentto the object “Telegr. operation2-fold” while a telegram is sent to thecorresponding object after a 3-fold ope-ration.If the parameter “Transmit value on eve-ry operation” is changed to “yes”, theinterface can send a telegram aftereach operation. This means that a tele-gram is triggered after a three-fold ope-ration to the objects “Telegr. operation 1-fold”, “Telegr. operation2-fold” and “Telegr. operation 3-fold”.

The “Maximum time between two ope-rations” indicates how long the interval(period) can be between multiple opera-tions so that it can still be considered amultiple operation.

It is possible to activate an additional1 bit object “Telegr. operation long” forthe evaluation of a long push button ac-tion. The period which is interpreted asa long operation by the input can be setbetween 0.3 s and 10 s. The transmittedvalue on detection of a long push buttonaction can be an ON, OFF or TOGGLEtelegram.


Pulse counter

When used as a pulse counter, the uni-versal interface can count up input si-gnals and send them on the EIB. De-pending on the parameter setting, up tofour communication objects are display-ed.

The parameter “Pulse detection on” de-termines whether input signals with afalling edge (normally closed contact) ora rising edge (normally open contact)are counted.

ABB i-bus® EIB

The interface can send the counter va-lues in three sizes: as 8 bit values(0 … 255), 16 bit values (-32.768 …+32.767 or 0 …65.535) or as 32 bit va-lues (-2.147.483.648 …+2.147.483.647). Depending on the sizeof the bit value, the ETS2 program dis-plays an 8 bit, a 16 bit or a 32 bit com-munication object “Input ... - Telegr.counter value ... bytes”. The new coun-ter value is sent to this object after eachoperation at the input.

The initial counter values can be para-meterised. All counter values start withthe value “0” by default.

The current counter value can be re-quested at any time via the EIB with the1 bit object “Request counter values”.To do so, a telegram with the value “1”must be received. The objects “Input ... -Telegr. counter value ... bytes” and anenabled object “Input ... - Differentialcounter ... bytes” thus send their currentvalues, regardless of whether these va-lues have already been sent.


After a bus voltage failure, the currentcounter value can be sent directly onthe bus. To do so, the parameter “Trans-mit counter values after bus voltage re-covery” must be set accordingly. Afterbus voltage failure, the counter valuesare reset to their initial values.

A further tab is activated in the ETS2program via the setting “Enable additio-nal options”. Special functions can beset here when the interface is used as apulse counter.By default, the pulse counter recordsevery operation at its input. With the pa-rameter “Divider: number of input pulsesfor one counter step”, the countingfunction can be adapted to individualrequirements.

The setting “Factor: one counter stepchanges counter value by” indicateshow many steps are counted upwardson detection of a pulse. If a negative va-lue is entered, the counter counts back-wards.

If the counter values should be sent cy-clically, the corresponding parametershould be set to “yes”. The cyclic timeis composed of a base and a factor.

Cyclic time = Base * Factor

If the differential counter is activated,the ETS2 indicates three further com-munication objects. The object “Input ...- Differential counter ... bytes” alwayshas the same bit width as the countervalue object. The two objects “Input ... -Differential counter overflow” and “Input... - Reset differential counter” are 1 bitobjects.

The differential counter has the samecounting function as the absolute coun-ter. In contrast however, it can be resetvia the object “Input ... - Reset differenti-al counter”. In addition, a counter over-flow can be reported on the bus via theobject “Input ... - Differential counteroverflow”. It is thus possible e.g. tomeasure daily consumption values viathe differential counter.

The overflow value of the differentialcounter can be set. If the differentialcounter reaches the set value, a “1” issent to the object “Input ... - Differentialcounter overflow” and the differentialcounter starts to count from the begin-ning.
