Abstract

The device has a terminal (4), by which a bus device (1) is connected with a bus master (15) over a configurable bus address (9,9a,9b). A connection system (5) has a distributor (8), a cable (7) and a connector (6). The configuration of the bus device is arranged in the connection system.

Description

The invention relates to a device for the configuration of bus subscribers via a connection technology.

So far, it is only known bus subscribers z. B. are arranged on a serial bus, a CAN bus, a Profibus or the like, to assign a single address, with each bus subscriber an unchangeable single address belongs.

For the sake of simplicity of description, in the following description, a bus subscriber in the embodiment as a rotary encoder will be described, although similar devices which can be connected to a common bus may be used.

Currently, the configuration of such bus users, which are designed as rotary encoders or similar devices, via the setting of the bus address and the baud rate. This is done either via selector switches, which are located in the encoder or this is done alternatively via a programming in the bus.

In this way, the respective rotary encoder is assigned a unique address.

The disadvantage, however, is that when a rotary encoder or other, configurable device must be replaced, the original, application-related settings (configuration) must be made either manually or via the bus again to be installed device.

This may, under certain circumstances, require a great deal of effort, or lead to errors, especially in difficult environmental conditions.

In addition, this requires a certain degree of training of the appropriate staff, or documentation effort.

The invention is therefore based on the problem of simplifying the configuration of bus subscribers on a bus system, without which it requires an adjustment of configuration data on the bus subscriber or on the bus master.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

An essential feature of the invention is that the configuration of the bus subscriber is arranged in the connection technology itself.

With the given technical teaching, there is the significant advantage that now in the connection technology, the configuration data for the bus subscriber are kept. In this case, the term "connection technology" is understood to mean all cables and connecting plugs, or also line distributors, which are able to combine a plurality of connection lines with one another, to which in turn the said bus subscribers begin.

This pursues the following new inventive approach:
The operating elements that enable the configuration are moved from the encoder to the connection technology or additionally provided there. This has the advantage that when the device is replaced, the device configuration in the connection environment is retained and does not have to be re-selected, or a standard device can be provided for initial installation and the associated necessary configuration can be made via the description of the wiring. This can be used / exchanged at different locations each "standard device", which then receives its configuration by merely mount or connect from the existing installation environment, because this is not an immediate part of the device.

• • Im Anschlusskasten/Verteiler/Schaltschrank die Konfigurationsleitungen entsprechend den Erfordernissen logisch verschaltet wird;
• • sich im Anschlussstecker eine entsprechende Verschaltung befindet, bzw. Schaltelemente eingebracht werden;

• • ein im Gerät eingestecktes Speichermodul, mit dem die Konfigurationsdaten mechanisch herausgenommen und in ein neu zu installierendes Gerät wieder eingesetzt werden.

This can be done as follows:
In the device connection area (eg connector or cable), configuration connections are provided in addition to the usual supply and signal connections. These configuration connections can be used to configure the device from outside the standard scope of delivery of the device. B. in that:

• • In the terminal box / distributor / control cabinet, the configuration cables are logically interconnected according to the requirements;
• • There is a corresponding connection in the connector, or switching elements are introduced;
• • a second connector is provided, which includes the logic interconnection;
• • In a corresponding "reader" a permanently encodable storage medium is introduced, which contains the device configuration. This can be z. B .: be a SIM card, a punched card, a visual, magnetic, capacitive, inductive or tactile readable storage medium;
• • A memory module inserted in the device, with which the configuration data are mechanically removed and reinstalled in a device to be newly installed.

Possible arrangements:

• • In the connector - bridges (pin to pin / core to core) - Configuration module (DIP switch, SIM card, reader + storage medium)
• • In a connection adapter (adapter before mounting the cable) - Setting options the same as in the connector - In a second, plug-in connector - Setting options the same as in the connector
• • In the cable - Wearable in the cable - adapter - Setting options the same as in the connector
• • In the control box / distributor box - digital bridges (A0 ... AX) - Voltage level - analog - Electrical / Electronic (DIP switch, SIM card, ...)
• • - in the device itself - as a removable / exchangeable configuration module / storage medium

Configuration data can be:

• • Address, baud rate, resolution, direction of rotation
• • Offset (Present or Limits
• • Software communication properties
• • Identification

Example of a 3-bit address coding of a CAN encoder at the 17-pin connector, the customer can now address coding via Adr. Common (pin 6) with the respective required address control inputs (pin 14, 17, 15) in the connector or at the cable end in the control cabinet.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following, the invention will be explained in more detail with reference to drawings illustrating several execution paths. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

Show it:

1 an embodiment of the prior art;

2 : the embodiment according to 1 in a modification of the invention;

3 an embodiment for implementing the idea according to 2 ;

4 : one opposite 3 modified version in which the address environment is laid in the distributor;

5 A further embodiment in which the address environment is kept in an external memory.

In 1 In general, a serial bus system is shown in which on a serial bus 14 on one side a bus master 15 and on the other side a variety of bus subscribers 16 are arranged.

As an example, there are two different encoders 1 . 1a as a bus participant to the serial bus 14 connected.

Every encoder 1 . 1a consists of a sensor 2 , an interface 3 , and a connection 4 , where the connection 4 concerning a connection technique 5 can be configured in any way as a plug or as a coupling. In the illustrated embodiment, the connection is made 4 with the connection technology 5 from a plug 6 that has a mating connector with a cable 7 connected is. This cable 7 is to a distributor 8th connected, in turn, to the serial bus 14 connected.

According to the embodiment 1 According to the prior art is now essential that the configuration of the different encoders 1 . 1a from the busmaster 15 the addresses of the respective encoders 1 . 1a over the distributor 8th , the cable 7 and the connection technology 4 . 5 . 6 is allocated. By appropriate programming at the bus master 15 thus becomes the rotary encoder 1 the unique and unique address 9a allocated during the rotary encoder 1a the unique address 9b is allocated. In this way, a separate addressing of the encoders 1 . 1a from the busmaster 15 guaranteed.

If now one of the encoders 1 or 1a becomes defective, he must of the connection technology 5 be replaced and replaced by another encoder. However, there is the disadvantage that the programmed bus address 9a . 9b lost goes, because the encoder 1 . 1a from the serial bus 14 was separated.

Would you now a new encoder 1 . 1a would need to re-program the address of the now exchanged rotary encoder 1 . 1a done, which is associated with high costs. This avoids the invention.

The 2 shows, in contrast to the embodiment of 1 that the unique address that the respective rotary encoder 1 . 1a is assigned, no longer from the bus master 15 over the serial bus 14 the encoder 1 . 1a is supplied. The invention now provides that the unique address of the encoder 1 is kept in the connection technology itself and permanently stored there. This means that the bus address 9a . 9b in connection technology 5 stored and held, this being either in the plug 6 , the cable 7 or the distributor 8th can be.

Thus, the present invention generally provides that the unique address is maintained in the non-exchanged portions of the entire assembly, which is entirely contrary to the prior art.

According to the state of the art 1 was the address in the replaceable encoder 1 . 1a kept and this is avoided according to the invention, but the unique address 9 . 9a . 9b is now kept in the non-exchangeable parts and stored there permanently.

Therefore, it is now possible for the first time that when replacing the encoder 1 or 1a in 2 the in the connection technology 5 . 6 . 7 . 8th reserved unique address now when connecting the rotary encoder 1 . 1a into the rotary encoder 1 . 1a is given, which simply queries the connection address and thus receives its unique address.

This is a significant advantage because it can now be connected to bare encoders connected to the serial bus 14 automatically their unique bus address 9 obtained without further adjustment measures required.

In 3 is shown as an embodiment that through the plug 6 and a corresponding mating connector 17 a fixed address A0, A1, A2 is provided, it can be seen that the address A0 has the value 1 and the address A1 and address A2 has the value 0.

This fixed bus address 9a or 9b will now be fixed in the non-replaceable plug 6 held up and the mating connector 17 , which directly with the encoder to be replaced 1 . 1a is connected, is neutral. Through this, the address line is simply looped through and the rotary encoder 1 . 1a fed.

This is in 3 recognizable to the first encoder 1 the fixed bus address 9a hardwired in the plug 6 is fed while for the rotary encoder 1a the bus address 9b hardwired in the plug 6 held by the mating connector 17 is looped through.

In another embodiment according to 4 is shown that the addresses A0, A1, A2 for the encoder 1 or 1a in the distributor 8th be kept fixed. This means that the fixed bus address 9a . 9b not in the plug 6 is arranged, but in the cable distributor 8th , in which a hard-wired bus address is maintained.

This has the advantage that even the cable set 7 can be kept neutral with its connection elements and can be replaced at any time, without requiring reprogramming.

In 4 is shown only schematically that the address line 18 Part of the cable 7 is, in which of course a number of other signals are transmitted.

In 5 is shown that the configuration is also in its own hard-wired configuration module 11 can be kept. The address shown there 20 then, for example, on a memory card 19 held, which is read out when needed, what then the address 20 in the direction of the arrow 10 in the direction of the arrow 21 when replacing the rotary encoder 1 automatically read by the encoder, thus the unique bus address 9 in the form of the address 20 is assigned.

The memory card 19 is designed for example as a SIM card. Of course, any other programmable or readable storage medium to the memory of the bus address can also be used.
