The designation of the channels is always in a consecutive alphabetic order. There are three possible functionalities for each channel: Disabled No function is set to the channel, so this channel does not contain of any communication objects. Channels grouped If you select a pair of channel as “channels grouped”, you will be able to parameterize the pair of channels as dimming‐function, shutter‐function or switching‐ function. Channels unique If you select a pair of channels as “channels unique”, you will be able to parameterize each channel for itself as switch, counter, scene, switch short/long, one button dimming or one button shutter. At the plus variant, there are additional 4 logic functions (and/or) containing of up to two additional input objects. Furthermore the plus variant contains of one bicolored LED per channel, which are individual parameterize able, and one bicolored operating LED.

A‐‐>0‐4 and channel B‐‐>5‐9). The numeration of the channels is always the same, even if some channels are disabled. At the plus variant, there are additional objects for the LEDs and the logic blocks. The communication objects for the logic follow on the objects for the channels. There are up to 12 objects for the logic function, so 12 numbers are reserved for the logic function, e.g. the numbers from 40 to 51 at an 8‐ fold push button. The communication objects for the LEDs start consequently with the first numbers after the logic blocks. According to the parameterization, one communication object per LED can be shown. So there are 9 objects at the plus variant of an 8‐fold push button and one blocking object. The follow The following illustration shows the communication objects for the channels. Channel A/B is selected as “channels grouped” and parameterized as a dimming function. The channels C/D are selected as “channels unique” thus every channel can become an individual function. Channel C is parameterized as switching‐function and channel D is parameterized as scene‐function. The channels E/F are also selected as unique channels. Channel E is parameterized as shutter and channel F as switch with the sub function “send status”. The channels G and H are selected as grouped with a shutter function: Illustration 4: Communication objects per channel MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de...

1. The parameter “Time for keystroke long” allocates a static value to the push button from when a long keystroke is recognized. This parameter is important for functions, which have different functions for a long and a short keystroke. 2. The limitation of telegrams can achieve that the bus gets not overloaded. An overloading of the bus‐system can cause long waiting periods, e.g. at pushing a button. If the limitation of telegrams is activated and more telegrams than allowed are send, the telegrams above the limitation will be send at the next time interval. Therefore an overload of the bus can be prevented. The parameter “Behavior at bus power up” defines the behavior of the push button at a bus power return. The setting “Read value for toggle” effects that all communication objects “value for toggle” are read. So the push button knows the current status of the objects. If you choose the setting “no read value for toggle”, the push button will not know the current status of the actor. So the push button assumes an unconfirmed value for the objects “value for toggle” and sends always a “0”‐signal at the next operation. Only now the push button knows the status of the actor and can send the right values. But if you choose the read of these values at a bus power up, the push button will send immediately the right value for toggling.

1 Dimming 4 Bit Dimming function; action for a long keystroke Chart 10: Communication objects dual surface dimming When a pair of channels is parameterized as dimming function, two objects are shown. One object reacts to a short keystroke, the switching object “Dimming on/off”, and the other object reacts to a long keystroke, the dimming object “dimming”. It is possible to parameterize this function as brighter/darker or as darker/brighter. The first function belongs always to the first button. If you switch this parameter, the function will be switched automatically. By choosing the dimming function (channel A/B) as brighter/darker, the function reacts in this way: A short keystroke at button A switches the lights on. The lights are switched off by a short keystroke at button B. A long keystroke dims the lights step by step until releasing the long keystroke. The lights are dimmed brighter at button A and darker at button B. The push button starts always with the last brightness level, before switching off. The step size is set fixed to 100% at the dual surface dimming. It is a start‐stop dimming. that means the lights are dimmed as long as you hold the button. After releasing the button a stop value is sent, which stops the dimming process. So you can dim the lights with only one keystroke from 0% to 100% or from 100% to 0%, by pushing the button long enough.

If you adjust a pair of channel as switch, the following parameters will be shown: Illustration 11: dual surface switching function Simple functions, like an alternating circuit, can be programmed easily by using the grouped switch function. The 1 bit communication object sends in dependence of the parameterization a 0‐ or a 1‐ signal for the first button and the inverted signal for the second channel. So you can chose which channel should switch off and which should switch on.

One button dimming One button shutter After the assignment of the operating mode the further parameterization can be done. If the channel is selected as inactive, no further parameterization will be possible. 4.5.1 Switch The switching function is for switching the corresponding output on, off and toggling it. There is a multitude of sub‐functions at the switching function, which enables the user to evaluate edges and integrate times to the switching process. The following parameters are shown, when the channel is selected as switch: Illustration 12: Parameter switch Various sub‐functions are available at a switching output. Most of these sub‐functions contain also of further parameterization‐options.

Off Chart 15: Parameter switch rising/falling edge The sub‐function “switch rising edge” or “switch falling edge” sends only a signal at the adjusted edge. You can parameterize whether a 0‐signal or a 1‐signal should be sent. There is no inverted signal at subsiding the edge. This function always sends only one adjusted signal. The following diagram shows this sub‐function for rising edges. As soon as the state changes from 0 to 1, the push button sends an On‐pulse (=1‐signal): The following chart shows the corresponding communication object: Number Name Length Usage 0 Switch 1 Bit Switching function, no differences between a long and a short keystroke Chart 16: Communication object switch rising/falling edge MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de...

Technical Manual Taster BE-TA55 To be sure that the push button toggles at every switching process, you have to connect the status object of the push button “Value for toggle” with the status object of the actuator. When the push button should work without an actuator, the object has to be connected to the switching object “switch”. The connection is important, because the push button cannot invert the signal, when it does not know its current state. By undocking this communication object, you have more choices to program the push button. So you can use the object “Value for toggle” for visualizations or additional functions and you will be more free in design your project. So you have for example the option to visualize the switching process by connecting the status‐object to a switching object of a LED or something else.

Technical Manual Taster BE-TA55 The parameter “Value for rising edge“ defines whether the channel should send an 1‐signal (value: On) or a 0‐signal (value: Off). If you want for example switch a channel of a switch actuator, you will have to choose different values for the rising and the falling edge. Otherwise the push button sends the same signal twice, for example an On‐signal. The cyclic sending causes that the state of the push button is sent periodically in certain parameterize able intervals. Then the push button sends the parameterized value for the corresponding edge. A common application for this parameter is for example the observation of windows, which are equipped with window‐contacts. So a display can for example show whether all windows are closed or not. Furthermore an alarm device can operate with this function. The following diagram describes this sub‐function. In this example, the push button sends a 1‐signal for a falling edge and a 0‐signal for a rising edge. Additional the diagram shows the connection with a switch actuator, which was parameterized with a normal switching function: MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de...

4.5.1.5 Send value with on/off delay The following setting options are available at the function “Send value with on/off delay”: ETS‐text Dynamic range comment [default value] Delay time 0‐60min Adjustment of the delay time [1s] for the sending process Chart 25: Parameter Send value with delay The sub‐function “Send value with on/off delay” allows that the push button sends its value after a parameterized time. At the on‐delay, the time starts when the associated button was switched on and at the off‐delay, the time starts when the associated button was switched off. The push button sends always its current value at this function. If the value changes before the time ran out, the on‐ delay will expire. For example, when an input with a parameterized on‐delay is switched off, before it was switched on, the input remains off.

Technical Manual Taster BE-TA55 The parameter “switch short/long” can control for example two channels of an actuator by using only one button. Furthermore you can switch a channel with a long keystroke on and with a short keystroke off. For both objects, a function can be set individually. Therefore the sub‐functions on, off, toggle and nothing are available. Two communication objects are displayed, which can be connected in any way. By activating the sub‐function “toggle” an additional communication object appears, called “value for toggling”. This object is a status object for the push button and must be connected to the status‐object of the actuator (have a look at: 4.5.1 Toggle) The following diagram shows the behavior of this parameter. Both objects (push‐button and push‐ button long) were set to toggle. The object for the long keystroke is connected to channel A of the switch actuator and the object for the short keystroke is connected to channel B: In this example the push button toggles Channel B with a short keystroke. The Channel A does not react to a short keystroke. This one reacts only at a long keystroke with toggling.

Technical Manual Taster BE-TA55 The following diagram shows a further application example for this parameter. In this example, the object for a long keystroke switches the channel A of a switch actuator on. A short keystroke switches the channel off.

Chart 33: Communication objects one‐surface dimming The one‐surface dimming performs the dimming process by using only one button. So it is possible to dim the lights by using only one button. A long keystroke addresses the communication object “Dimming”, which is for the dimming process. The short keystroke addresses the communication object “Dimming on/off”, which is for the switching process. Because of having only one button for performing the dimming process, the direction of the dimming process changes after every dimming process. That means, if you dimmed darker once before, the next time the lights will be dimmed brighter and the other way around. The values for the dimming steps indicate how much the lights should be dimmed by along keystroke. It is here a start‐stop dimming, which means you send as long a brighter or darker telegram as you push the button. As soon as you release the button, a stop telegram is sent, which stops the dimming process. So you can dim from 0% to 100% or from 100% to 0% if the dimming step is set to 100% by pushing the button long enough. At a value of, for example 12,5%, 8 dimming processes are necessary to dim the lights by 100%. When the telegram repetition is deactivated, you cannot dim the lights more than the value, which you have selected for the dimming steps, because the direction of dimming changes after every dimming process. You can additional adjust how long the push button should wait between the single dimming steps by the repetition time.

Technical Manual Taster BE-TA55 The diagram shows the one‐button dimming without repetition with an adjusted dimming step of 25%: The lights can only be dimmed between the limits of 0% to 25% and 100% to 75%.

Technical Manual Taster BE-TA55 Consequently, you have to activate the repetition of telegrams if you want to dim the lights over the adjusted dimming step. By activating the repetition of telegrams, a new window is shown to adjust the repetition time. The repetition time indicates in which time intervals the brighter/darker telegram should be repeated. As long as the dimming function is activated by a long keystroke, the push button sends the accordingly telegram. The following diagram shows this function with an adjusted dimming step of 25% and a repetition time of 1s: Now it is also possible to dim the lights by 100%, by using a dimming step less than 100%. The telegram is repeated as long as the maximum or the minimum is reached. Between the repetitions the push button waits the repetition time.

0 Shutter 1 Bit Driving function of the shutter, action for a long keystroke 1 Blinds/Stop 1 Bit Stop/ Adjustment of blinds; action for a short keystroke Chart 35: Communication objects one‐surface dimming The one‐surface dimming is performed by using only one channel. The communication object “Shutter” is addressed by a long keystroke and performs the up‐ and down‐movement of the shutter. The direction of movement depends to the last direction of movement. If the shutter were driven up at the last time, they will be driven down at the next time. So the direction of movement changes after every movement. The communication object “Blinds/Stop” is addressed by a short keystroke. Addressing this object stops a running movement of the shutter. Furthermore it will adjust the blinds if a shutter function is selected for this channel. The direction of the adjustment changes also here after every movement in the same way like the up/down moving of the shutter.

change of output Output inverted No Adjustment indicates, whether the Yes output should be inverted or not Chart 39: Logic sub‐function switch The sending condition adjusts, when the push button should send a signal on the bus. By adjusting the sending condition “change of input”, the push button sends a signal at every change of any input whether that causes a change of the logic operation or not. The setting “change of output” causes that the push button sends only a signal when the logic changes its current status. The sub‐function Output inverted indicates whether the output signal should be issued inverted (that means reversed 1‐>0 and 0‐>1) or normal. The following diagram shows the logic operation switch as an and‐function. The logic reads in this example the channels A and B as well as an external logic object. The Output is inverted: MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de...

Technical Manual Taster BE-TA55 The logic function is only satisfied, when button A and B as well as the external logic object have a 1‐ signal. The inversion of the output causes that the output is switched on, when the logic is not satisfied and switched off, when the logic is satisfied.

This logic function calls scenes, when the logic function is satisfied. The chart shows the possible sub‐functions for the logic operation scene: Sub‐function Dynamic range comment [default value] Scene number 1‐64 Scene number must be the same like the [2] one you want to call with the logic‐function Chart 40: Logic sub‐function scene The logic function for the scenes works like a normal logic function. As soon as the logic function is satisfied, the communication object will send the adjusted scene‐number. The communication object has the length of 1 Byte, so that it can be connected to other communication objects of scenes. All sub‐functions, like in a normal logic function can be parameterized. So you can set the logic function as an AND‐ or an OR‐function and connect all inputs of the push button and additional 2 external logic objects to the logic function.

Technical Manual Taster BE-TA55 4.7 LED lights (only at the plus variant) The functions, described in this segment (4.7), are only available at the plus variant. The LED display can visualize different switching processes and keystrokes. Every LED can light green or red. You can also parameterize when the LE D should light green and when red. The Illustration shows the configuration of the LED display: Illustration 22: Configuration LED display The push buttons (at the plus variant) contains of one LED per button and one orientation LED. Additional a blocking object for the LEDs can be shown, which blocks all LEDs. The parameterization of the LEDs is described in the following segments.

The LED is switched off and cannot be controlled. So there are no following parameterization options for this LED. external object If the LED should react to an external object, a communication object will be shown for this LED. The communication object can be connected to any group address afterwards. So the LED can also show a switching process of an actor, which is independent from the push button. The chart shows the according communication object: Number Name Length Usage LED 1‐2/4/6/8 1 Bit switch LED Chart 42: Communication object external object LED The number of the communication object depends to the hardware design (2‐fold/4‐fold/6‐fold/8‐ fold) and the used LED.

Illustration 24: Configuration internal connection LED Because there is already a fixed connection between the LED and a communication object, now further communication object is necessary. The LED can be connected to every object independent from the size of the object. button activation By choosing this action, the LED reacts to every activation of the associated button. The action how the LED should react to an activated/inactivated button can be parameterized individual by the function LED characterization. The value for “on” will be send when the button is activated and the value for “off” when it is not activated. Further can be set for the LED when they should switch the green light on/off and when the right light on/off. This behavior can be adjusted by the parameter “LED characterization”. The dynamic range is shown in the chart 33 (former side). Thereby the first value stands for the switched state and the second for the deactivated state. Additional the luminescent behavior can be set of every LED individual by the parameter “State of green/red LED at ON”. Every LED can shine permanent or flashing.

over ext. object 0=ON, 1=OFF Chart 43: Dynamic range LED orientation light Four choices are available for the controlling of the orientation light. Firstly the LED can be switched permanent off. So the LED is deactivated and has no further functions. If the LED should be used as orientation light, the setting ON switches the LED permanent on. Furthermore the orientation LED can be controlled by an external object. For this setting can be additional adjusted at which signal the LED should switch on. By activation the controlling by an external object, an additional communication object will be shown. This communication object can be controlled of any device. The following chart shows the communication object for the controlling by an external object: Number Name Length Usage 30/40/50/60 LED orientation light 1 Bit switch LED Chart 44: Communication object LED orientation light MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de...
Activation of the blocking object for the LEDs LEDs Yes Chart 45: Dynamic range blocking object LEDs In difference to the blocking objects per channel, there is only one blocking object for the LEDs, which blocks all LEDs. When the LED blocking object is triggered, that means the blocking object becomes a logical “1”, all LEDs are blocked and cannot be controlled while the blocking function is active. The LEDs, which were switched on before the blocking process, are switched off. By sending a logical “0”, the blocking process is deactivated. Now it is possible to control the LEDs as usual. The chart shows the associated communication object: Number Name Length Usage 31/41/51/61 LED blocking object 1 Bit blocks all LEDs Chart 46: Communication object blocking LEDs MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de...
Technical Manual Taster BE-TA55 4.7.4 LED priority The LED priority can allocate every LED, except the orientation light, a certain behavior at the activation of one of the both priority objects. To configure the LED priority, you have to activate this function at the LED configuration: Illustration 27: Activation LED priority When the LED priority is activated, a sub menu “LED priority” appears at the left drop‐down menu. The further parameterization can be done at this submenu: Illustration 28: Sub menu LED priority There is a parameterization option for every LED (except the orientation light) at this sub menu. Every LED can react either to the first priority object or to the second. You can also set whether the Led should react to a 0‐signal or a 1‐signal of the priority object.
