System of subscriber stations of building system technology
5

The invention relates to a system of subscriber stations and devices connected to them in building systems technology, in particular in the case of a bus connection, in which the assignments and in particular functions are programmable and in which at least one subscriber station has a control panel. In building systems technology it is usual to connect special programming devices to the bus in order to program the subscriber stations or the bus devices connected to them. The bus devices, such as lights or blinds, can also be combined with the subscriber stations. In this case the subscriber station only has the function of a bus coupler.

The invention is based on the object of developing a system that is particularly economical and space-saving with regard to programming.

The solution to the problem described is achieved according to the invention by a system according to claim 1. Here, at least one subscriber station with control unit is provided with a special initialization program for programming subscriber stations. This makes it possible to save a separate programming device that has to be connected to the bus. The subscriber station can be a bus device, such as a switch or an input for sensors as well as generally an output to actuators. According to the invention, such a subscriber station with control unit is used for programming subscriber stations, in particular the subscriber station itself, by equipping the subscriber station for this purpose. In order to avoid input errors

To resolve this problem, it is advantageous to be able to switch off the addressing mode in the initialization state by means of a special input.

A subscriber station for a system of the type described is preferably loaded with a special initialization program, for example by providing a suitable circuit board. It is also sufficient to design a subscriber station in such a way that a special initialization program can be loaded.

A system of subscriber stations of the type described can also have at least one subscriber station with a control unit that is provided with a device for programming subscriber stations.

The invention will now be explained in more detail using an embodiment shown schematically in the drawing:

The drawing shows a system of subscriber stations 1 that are connected to each other via a bus. Bus lines 2 to 5 are connected to a bus system via bus couplers 6. Some of the bus couplers 6 are arranged in distribution devices 7.

One of the subscriber stations 1, the subscriber station 8, is provided with a control panel 9, as are several other subscriber stations. The subscriber station 8 is also provided with a special initialization program for programming subscriber stations 1. This can be a device 10 for programming subscriber stations 1. Such a device can be designed as a circuit board or as a memory in a type of microprocessor. The subscriber station 8 can also generally be designed so that it can be loaded with a special initialization program.

On the other hand, it can also be designed in such a way that it can be loaded with a special initialization program.

The subscriber station 8 and the subscriber station 1 can be designed as bus devices. The subscriber stations 8, which are provided with an initialization program for programming subscriber stations, use the existing control panel for programming additional subscriber stations. The bus coupler is switched to programming mode, for which a special initialization program can be used. Such an initialization program can be set up or loaded during production or by the customer.

To indicate that a bus device or a participant station is in programming mode, parts of existing actuators, such as LEDs or LCDs, and generally outputs or relays, can be used.

It is useful if, in order to correct input errors, for example when pressing several addressing keys, an input or an automatic function, a so-called standard message, is provided that switches off the addressing mode. The addressing process can then be re-established.
