• c) Automatische Zuordnung der physikalischen Position zu dem Slave-Modul durch Betätigung des ersten Bedienelementes oder eines dritten Bedienelementes, wobei die Position die Startposition bzw. die der Startposition nächstfolgende freie physikalische Position einer Positionsfolge ist.

The object of the invention is achieved by a method for assigning a physical position to at least one slave module and / or for assigning a physical position of at least one channel of at least one slave module in a decentralized, event-controlled bus system with serial data transmission for controlling, monitoring and reporting operational functions of the at least one slave module, where at least one slave module and at least one master module are assigned to the bus system, solved, wherein the following steps are performed successively on the master module:

• a) selecting a startup mode by operating at least a first control element of the master module;
• b) selecting the at least one slave module by simple or multiple actuation of a second operating element of the master module;
• c) Automatic assignment of the physical position to the slave module by actuation of the first control element or a third control element, wherein the position is the start position or the start position next free physical position of a position sequence.

By Such a method can easily and quickly assign a physical position to at least one slave module in a decentralized, event-driven bus system, so that an assignment to the slave module is made possible by a software. Furthermore, a modular installation device is to be created which is simple and fast to a decentralized, event-driven Bus system can be connected.

From a master module can a variety of different slave modules are controlled and a position or a position number within the bus system, to which they are connected. Such a procedure allows a decentralized assignment of the position of a Slav module within a bus system, since the master module also on the bus system connected.

A slave module may be a sensor module, ie a commander, or an actuator module, ie a command receiver. For example, sensor modules can be elements for converting physical quantities into electrical values. These can be touch, temperature or brightness sensors. When Subscribers to the bus system process physical parameters and if necessary send a telegram on the bus line of the bus system. Actuators are participants in the bus system that receive, process and perform functions.

The Actuators receive over the bus line switching commands, for example, when using push button sensors and triggered by switches on pushbutton interfaces or be discontinued by wind and brightness sensors. After receiving The switch actuators decode these commands and then perform the desired function out. For example, they switch a lamp or lighting group on or off.

The Actuators feature all over an integrated bus coupler, each require only a single Application and are just about a bus terminal connected. In addition, numerous software can be used Set properties: So can the exits the switch actuators as normally open or opener defined and freely assigned as required with some functions become. Furthermore they can each be assigned a time function. That too Behavior of the outputs for bus voltage failure and return be determined by software.

actuators can For example, lights, blinds, air conditioning, ventilation, Be heaters or motors. Sensors are for example thermostats, Infrared emitters, anemometers or brightness sensors.

The Bus system is preferably the European installation bus system (EIB). Of course, other bus systems can also be used.

at the procedure is first a startup mode by operating at least a first one Control element of the master module selected. The control element can be in the simplest case, a probe element. After selecting the Commissioning mode, all connected to the bus system slave modules listed. A slave module will then be single or multiple activity a second control element of the master module selected. D. h., all not yet selected slave modules are displayed one after the other. This can be done, for example, on a display device of the master module or on the slave modules themselves. The slave modules can, for example have small lamps that light up when the respective slave module selected becomes. Is that what you want Slave module selected, takes place in a next Step an automatic assignment of the physical position to the slave module by actuation the first control element or a third control element, wherein the position the start position or the start position next free physical position of a position sequence is. That is, after Selecting a slave module becomes the physical position of the slave module in the bus system by actuating the first control element or a third control element. The position sequence is preferably a sequence of numbers, which usually starts with 1. Is in the bus system yet no slave module assigned a position been received the selected one Slave module the first position from the position sequence. For example receives the first one dialed Slave module the position number 1. After the automatic assignment the position or the position number to the first selected slave module by simple or multiple actuation of the second control element of the master module a next Slave module selected if there is another slave module. After dialing one next Slave module can in turn by the Actuate supply of the first control element or the third control element determines the position of this slave module be, this being the next one free position number from the position sequence, for example the Item number 2, receives. So can gradually all the slave modules coupled to the bus system be assigned a position in the bus system. The next selected slave module, which has not yet been assigned a position in the position sequence next, Assigned not assigned position number. In this way and Way can be easily and quickly connected to anybody connected to the bus system Slave module to be assigned a position in the same way as the User wishes. The order of the slave modules, d. H. the position of the slave modules, depending on the wishes individually determined by the installer.

to automatic assignment of the physical position to the slave modules For example, the first control element can be actuated. It recognizes the master module that after a slave module has been dialed is, by the operation the first control element an assignment of the physical position to be done to the slave module. The master module knows when pressing the first operating element, after the second operating element was previously actuated, that a physical position is assigned to the slave module should. Alternatively, the automatic assignment by the operation of a further control element, d. H. a third control element, take place. In this case, then the third control only has the function of assigning the position to the currently selected slave module. The first control then only serves to select the commissioning mode.

to execution The process requires a minimum of two controls. D. h., it is sufficient if the master module is a first and a having second control element. The first control element takes over the function of selecting the commissioning mode and the automatic assignment of the physical Position of the selected Slave module. The second control element is used to select a Slave module.

The Controls can simple key elements, such as pushbuttons or buttons on a touch screen, be. It can through the operation the second control element, the slave modules in one direction only in succession selected become. The one second control does not allow the slave module selected in reverse order can be.

such Slave modules have a channel, giving the channel the position number assigned to the slave module.

Prefers is further a method in which the selection of the commissioning mode by a longer one activity of the second operating element, in particular by an actuation of two to five Seconds, or that the second control element has two key elements wherein selecting of commissioning mode by simultaneous operation of both key elements he follows. This method uses the second control element for different Functions. The first function is to select the commissioning mode. The second function is dialing a slave module. By a longer one activity of the second operating element, in particular by an actuation of the second control over two to five Seconds, the commissioning mode of the bus system is selected. After this the commissioning mode is selected may be due to "normal" operation of the second control element of one of the slave modules are selected. For this is the second control element is pressed once or several times until the desired Slave module selected is. After selecting one of the slave modules, this will be automatic assigned a physical position in the bus system when the first or alternatively a third operating element is actuated.

alternative to the longer one activity of the second operating element may be the selection of the commissioning mode also by the simultaneous operation two key elements of the second control element done. Ie., In this alternative, the second control element has two key elements on, which operates simultaneously Need to become, to the function of selecting to realize the commissioning mode.

at In this method, the slave modules also have a channel, so that after assigning the physical position to the slave module the position of the channel of the position of the slave module within corresponds to the bus system.

Farther preferred is a method in which by single or multiple activity the first key element of the second control element several slave modules be selected one after the other or by simple or multiple actuation of the second key element the second control element several slave modules in reverse Order selected become. By the two key elements of the second control element Is it possible, select the slave modules connected to the bus system in two directions. Usually a slave module can only be selected again if it has been replaced by several times Press the second control element, the slave module is back on the line. Ie., For example, if thirteen slave modules are coupled to the bus system, they would be consecutive all thirteen slave modules selected Need to become until the desired Slave module reappears to give this a physical position assigned. The second key element allows the slave modules to be reversed be selected. D. h., Is too fast by pressing the first key element the desired Slave module ignored may be by operation the second key element the passed Slave module can be quickly re-dialed, there by operation the second key element of the second control element, the slave modules selected in reverse order can be. It can by the operation of the second key element a step backwards, so to speak.

Also particularly preferred is a method in which the first or the third control element have two key elements, wherein a simultaneous selection of both key elements of the first or the third control element, a channel selection mode for the selected slave module is selected, wherein after selecting the channel selection mode by simple or multiple actuation of the second control element, in particular by one of the two key elements of the second control element, the channel or channels of the selected slave module is selected / and wherein after selecting a channel of the selected slave module by pressing the first or the third control element, in particular by one of the two key elements of the first or the third control element, the assignment of the physical position of the selected channel is determined. The aforementioned control elements can advantageously also be used to select the channel selection mode and to assign the physical Position of the selected channel are used. If a slave module has several channels, each channel can be assigned a physical position. For example, a slave module may have 2, 4, 8 or even more channels.

The first or the third control element each have two key elements on. By a simultaneous actuation of both key elements of the first or third control becomes a channel selection mode for the selected Slave module selected. Depending on how many channels has a slave module can this by simple or multiple actuation of the second control element, in particular by a single or multiple actuation of a the two key elements of the second control element to be selected. After dialing, d. H. the selection of a desired channel becomes this by renewed operation the first or the third control element, in particular by the operation one of the two key elements of the first or the third control element, assigned a physical position. In this way can successively all channels a slave module a physical position, d. H. a position number, be assigned. When selecting the channels, it is preferable that Channels, to which a physical position has already been assigned, not be selected again can. channels which a physical position is assigned can separately be controlled so that the physical position can be changed later can.

One Method in which each channel of a slave module has a control lamp, in particular an LED, is assigned, and that the control lamp of a channel when this channel is activated by the operation of the second control element, in particular by pressing one of the two key elements the second operating element is selected, is particularly preferred. This allows the installer to recognize which channel of the selected slave module the physical position is assigned. A control lamp sits advantageously directly on each channel. This is possible also over a greater distance recognize which channel is selected was assigned to the physical position. It can do that Master module for example at a distance of one or more meters from the respective one Slave module can be located remotely. Particularly suitable are LED lamps, because these are not additional Generate heat.

To the automatic assignment of the physical position to a Slave module, this slave module is no longer available for re-dialing provided the second control. The same applies to one Channel of a slave module. After the assignment of the physical Position to a channel, this is ignored in the further selection.

Prefers is also a method in which the assignment of a physical Position of a slave module after selecting the slave module a longer one activity the first or the third control element, in particular by an operation from two to five Seconds, is deleted. In this way, a physical position or a Item number changed become. For example, consider a slave module instead of another Slave module a specific position number within the bus system received, so must first the already assigned position number will be released again. That is, the physical position of a slave module can after selecting this slave module through a longer one activity the first or the third control element, in particular by an operation from two to five seconds, deleted become. Thereafter, this physical position or the position number be reassigned to a slave module. The deleted item number forms in the position sequence, which contains the still to be assigned Positionsnum numbers, the next possible free Item number, so that these automatically forgive again first becomes.

According to the second aspect of the invention, the object is achieved by a master module for assigning a physical address to at least one slave module and for assigning the physical position of at least one channel of at least one slave module in a decentralized, event-controlled bus system with serial data transmission for controlling , Monitoring and reporting operational functions of the at least one slave module, solved, wherein the master module has at least two controls for performing one of the previously described methods. That is, at least two controls are required to perform one of the methods. So it is sufficient if the master module has the second and the third control element. By alternating operation of the controls or by prolonged operation of one of the controls, all the above-mentioned process steps can be performed. Thus, for example, by a longer actuation of the second control element, in particular by an actuation of the second control element for 2 to 5 seconds, the commissioning mode can be selected. Thereafter, a slave module can be selected by a single or multiple actuation of the second control element of the master module. The so-called selection is done by a short operation of the second control element. Subsequently, by actuation of the third control element, an automatic assignment of a physical position to the slave ve module, where the position is the start position or the free position next to the starting position of a position sequence.

has the master module another control element, d. H. the first control, For example, the first control element can be selected be used in commissioning mode. After selecting the commissioning mode can the second and third controls used as previously described become. D. h., By a single or multiple operation of the second control element of the master module, a slave module can be selected. Subsequently can by operation the third control element an automatic assignment of a physical Position to the slave module, where the position is the starting position or the next following the start position free physical position of a position sequence is. The position sequence preferably has an alphanumeric digit.

Prefers is also a master module characterized in that one of the controls and / or two of the controls and / or all three controls have two key elements / have. By Such a trained master module, the implementation of the previously described method be made more user-friendly.

So is a master module conceivable, which has two operating elements, wherein both controls each have two key elements. D. h., it is a master module conceivable with a second control element with two button elements and a third control element with two Key elements. To select the commissioning mode both Button elements of the second control element operated simultaneously. After that is achieved by simply and repeatedly pressing one of the two key elements of the second control element, a slave module is selected, wherein the slave modules are called in two different directions can be. By means of the two key elements of the second control element, the Slave modules in both Directions selected become. Case the slave module has only one channel, the channel can be the same physical Position or the same position number to be sorted as the slave module. This is done by pressing one of the two key elements of the third control element. Does the slave module have more than one Channel on, can the channels by simply or repeatedly pressing one of the two key elements of the third control element are selected and after the selection by operation one of the key elements of the second control element with the physical Be provided position.

The Controls can be formed in the form of push buttons or push buttons. Further can the controls be buttons on a touchscreen.

According to the third Aspect of the invention is the object by a modular structure installation device in series design, with a slave module and a master module, solved, wherein the master module as described above and for carrying out the previously described method is formed. The slave modules can Sensors, d. H. Commands, or actuators, d. H. Command receiver, be. The actuators can for example, dimmers, switches, regulators of lights, blinds, alarm systems, Air conditioning, ventilation, Be heaters or motors. Sensors are for example thermostats, Infrared emitters, anemometers or brightness sensors. DIN rail systems means that such devices are designed to be in a distribution cabinet, in particular at one Retaining rail or DIN rail to be fastened. The slave modules and the master module has the controls on the front. Also possibly existing control lamps are preferably on the front provided the respective module.

The Invention will now be described by way of embodiments with reference explained in more detail in the accompanying drawings.

After selecting a slave module, an automatic assignment of the physical position to the slave module by pressing the third control element 3 , Where where the position is the start position or the free physical position of a position sequence next to the start position. This is preferably an alphanumeric number, starting with 1. D. h., The first selected slave module receives by pressing the third control element 3 the position or the position number 1. The next selected slave module receives the position or the position number 2 until each slave module coupled to the bus system is assigned a physical position or a position number from the position sequence. After assigning the physical position or the position number to each slave module, each slave module can be controlled and put into operation by software.

In the 2 is a master module 1 with only two controls 2 . 3 shown. For carrying out the method for assigning a physical position to at least one slave module, it is also possible only two operating elements 2 . 3 to use. The selection of the commissioning mode for the commissioning of the coupled to the bus system, not shown, slave modules takes place in a first step by a prolonged actuation of the control element 2 , After selecting the commissioning mode, press the control element 2 a slave module selected.
