Description

The present invention is based on a designed according to the preamble of the main claim electrical / electronic actuator of building system technology.

Such electrical / electronic actuators are usually intended to influence on their channels in a particularly comfortable manner a variety of installed loads in buildings, such as blinds, lighting equipment, sensors, security, etc., as needed. For this purpose, electrical / electronic actuators have become known with various functionalities, which are preferably designed as DIN rail mounted devices. Often, such electrical / electronic actuators are provided for connection to a bus system. As an actor in this context, a gateway is to be considered, which connects two bus systems in terms of data technology.

By the DE 103 31 164 A1 has become known to the preamble of the main claim corresponding electrical / electronic actuator. This electrical / electronic actuator is provided for connection to a bus system of building system technology and has to influence associated, or associated loads on multiple channels. There are a plurality of actuating elements for influencing associated loads, wherein the actuating elements also serve for programming and / or influencing an internal functional module of the actuator. In addition, several display elements are available. In such a trained electrical / electronic actuator, however, there is a risk that unauthorized persons can easily make an influence on associated or associated loads via the actuating elements as well as a reprogramming or influencing of the internal functional module. Especially with large installations, such accessibility by unauthorized persons is not desired.

Starting from such a trained electrical / electronic actuator of building system technology, the present invention seeks to provide an actuator or a gateway, in which the unauthorized access for influencing associated loads and / or reprogramming or influencing the internal functional module effectively is prevented.

According to the invention this object is achieved by the features specified in the main claim.

In such a design is particularly advantageous that the unauthorized access is effectively prevented by particularly simple and inexpensive measures.

Further advantageous embodiments of the subject invention are specified in the subclaims. Reference to an exemplary embodiment, the invention is explained in more detail in principle, showing:

1 : in principle, such an electrical / electronic actuator with eight channels as a block diagram;

2 : in principle, such an electrical / electronic actuator with eight channels in plan view.

Typically, such an electrical / electronic actuator or such a gateway consists essentially of a, consisting of plastic, provided for receiving functional elements housing G, wherein a plurality of functional elements at least on a specified in the housing G circuit board 1 are arranged. Also the internal function module 2 is how particular out 1 appears on this electrical circuit board 1 arranged and executed as a microcontroller. In addition, in particular the 2 It can be seen that the present actuator is designed as a rail-mounted device.

As further shown in the figures, the actuator is provided for the building system technology and equipped with eight channels K to drive loads L such as lights, motors, ballasts, and so on. For influencing associated loads L are two first interfaces 3 provided via which a connection to a bus system (BUS) can be made. To be able to make a manual influence of associated loads L, if necessary, the actuator has four actuators 4 on, with these four actuators 4 also for programming and / or influencing the internal function module 2 are provided. There are also three display elements 5 provided the four actuators 4 assigned. The internal function module 2 is functional with the four actuators 4 and the three display elements 5 in connection. The functional module 2 has a locking device 6 on that with a code memory 13 is equipped and also functionally with the four actuators 4 and the three display elements 5 communicates. In addition, further display element may be present, the z. B. the eight channels K are assigned.

As in particular from 1 shows that is executed as a microcontroller function module 2 on a housed in the housing G of the actuator circuit board 1 arranged. The functional module 2 essentially has an evaluation stage 7 , the locking device 6 , an application unit 8th and a drive stage 9 on. The four actuators 4 are above the evaluation level 7 and the locking device 6 with the application unit 8th in connection, which on the one hand with the two first interfaces 3 for connecting two bus systems BUS and on the other hand with the eight channels K is in communication. In addition, the application unit is available 8th via an exit 11 with an electronic switching stage 12 the locking device 6 and via this electronic switching stage 12 via the activation stage 9 with the three display elements 5 functionally related.

Upon delivery of the actuators an access code is programmed into this, which is reproduced via a sticker A. About the four operation buttons 4 the user can enter the access code (1441) and thus unlock all functions. For this purpose, the four actuators 4 Code functions assigned, so that a first actuator 4.1 , a second actuator 4.2 , a third actuator 3.4 and a fourth actuator 4.4 available. According to the additional digits, the access code (1441) can then be accessed via the four actuators 4 be entered.

In order to deny unauthorized persons access to the functional possibilities of the actuator, the sticker A is removed by the installer after successful commissioning, whereby the access code is no longer accessible to unauthorized persons. Normally, the actuator is in the locked state, so that the unauthorized access for influencing associated loads L and / or the reprogramming or influencing the internal function module 2 is effectively prevented. In the locked state is over the three display elements 5 the normal operating status of the actuator is displayed. Now, if the lock can be canceled, the user of one of the four actuators 4 operate, bringing the three display elements 5 be converted into a slow flashing mode. Now, the correct access code (1441) must be via the four actuators 4 be entered. The user has only ten seconds to complete this process. If the correct access code (1441) has been entered, this will be indicated by a quick flashing of the three display elements 5 approved. If the access code (1441) is not entered correctly, or if it is timed out, the three display elements will change 5 the mode, whereby the normal operating state of the actuator is displayed again. If the actuator has been unlocked by entering the correct access code (1441), the user has the option of influencing the associated loads L as usual or reprogramming or influencing the internal function module 2 by appropriate actuation of the four actuators 4 make. After a lapse of one minute, the actuator automatically returns to the locked state.
