Definitions
- the invention relates to a method for commissioning a subscriber in a network as well as subscribers in the network.
- Networks are associations of different technical primarily independent systems, in particular computers, but also sensors, actuators, radio technology components, etc., so that a communication of the individual systems with each other is made possible.
- the individual systems are referred to as network nodes, as nodes or as participants in the network.
- the communication between the participants takes place via various media, such. B. WLAN or LAN.
- Networks are also used in automation technology. As such, they are part of automation systems that z. B. be used to carry out process engineering processes. The individual participants can perform different or even the same tasks in the automation system. Correspondingly, the individual subscribers are identical or different devices.
- a transmitter which is connectable with a communication interface as a participant in a network with multiple participants.
- a microprocessor is integrated into the transmitter for processing the signals recorded by a sensor at a measuring point.
- a processing program of the microprocessor can be adapted to the respective measuring task with numerous parameters. For example, the zero point and span, damping or the output signal in the case of an error as well as the characteristics of the transmitter can be entered as parameters. After entering these data electronically stored in the transmitter.
- further subscriber-specific data must be stored in the subscriber, which relate to the configuration of the network, so that the transmitter can be operated as a subscriber to the network and can exchange data with the other subscribers via the network.
- the electronic storage of data in the transmitter itself involves the problem that in case of a device failure, the data may not be retrievable at the transmitter.
- the housing of the transmitter is provided with a lockable space in which an information carrier can be stored with the data.
- the information carrier contains all the subscriber-specific data required for the operation of the subscriber on the network.
- the information carrier can be plugged directly into a replacement device.
- the information carrier is plugged into a programming device that transmits the subscriber-specific data via a communication interface to the replacement device.
- the published patent application DE 101 0 805 A1 describes a network with several subscribers. The participants can exchange data via communication links.
- a first subscriber can be parameterized and / or configured by storing subscriber-specific data.
- a second subscriber has a memory in which subscriber-specific data for parameterization and / or configuration of the first subscriber can be stored. The first subscriber is configured to transmit his stored subscriber-specific data to the second subscriber when he is reconnected to the network.
- the second subscriber is configured to store subscriber-specific data of the first subscriber received in his memory and to transmit this data via the communication connection to the first subscriber when it is restarted or exchanged for new parameterization and / or new configuration ,
- the replacement device that is to say by the first subscriber
- the replacement device by means of methods of autopilot detection, which subscriber is currently the neighboring one in the network and has stored the subscriber-specific data of the respectively exchanged network subscriber.
- the disadvantage of this is that the subscribers in the network therefore have to be informed about the topology of the network.
- the object of the invention is therefore to specify improved methods for starting up a subscriber in a network. It is also an object of the invention to specify improved participants which are designed for carrying out the methods according to the invention.
- the objects underlying the invention are each achieved with the features of the independent claims. Embodiments of the invention are indicated in the dependent claims.
- the invention specifies a method for starting up a first subscriber in a network with several subscribers. According to the method, at least a second subscriber of the network collects information about the multiple subscribers of the network. Further, the second party receives a request from the first party. The first
- Participant has been previously introduced as a replacement for a third participant in the network.
- the first participant requests information for his commissioning from the second participant.
- the second subscriber determines which subscriber is no longer in the network and, in the event that only the third subscriber is identified as being no longer in the network, the information collected about the third subscriber is transmitted to the first subscriber.
- the at least one second participant collects, for example, by a regular or from time to time taking place
- Communication with the multiple participants Information about the participants in the network.
- the second participant can therefore determine that the third participant is no longer in the network.
- the detection of the absence of the third party can therefore be done before the replacement of the third party, i. if the third party breaks down, by the first participant or only after the replacement of the third
- Participant held by the first participant After the first participant has been introduced into the network, the latter now sends a request to the second participant. The latter then supplies the information collected via the third subscriber to the first subscriber so that he can start his operation in the network.
- the method according to the invention has the advantage that subscribers can be exchanged without prior background or configuration and parameterization in a network.
- the participants can therefore be installed directly into the network without configuration and parameter assignment in order to replace failed users.
- the determination is made as to whether the first participant replaces the third participant or a fourth participant if the fourth participant is also determined to no longer be in the network. If the second subscriber has identified the first subscriber as a replacement for the fourth subscriber, the second subscriber transmits the information collected for the fourth subscriber to the first subscriber. Otherwise, the information collected about the third participant is transmitted to the first participant.
- the third and the fourth participant fail in the network and thus are no longer detected in the network. If the second subscriber now receives a request from the first subscriber by means of which, as already mentioned above, the first subscriber requests information for its commissioning, the second subscriber must first determine whether the first is to replace the third or the fourth subscriber. This is done z. B. by means of rules or by comparing the device type of the first participant with the device types of the no longer located in the network participants.

- By several participants or all participants in the network described for the second participant functionality for performing the method according to the invention it is ensured that even if a relatively large number of participants in the network these participants can be replaced by other participants and then in accordance with the invention Operation can be taken.
- the second subscriber forwards the information collected about the subscribers in the network to the subscribers in the network, e.g. by means of a communication taking place from time to time.
- false information that a participant has collected about another participant can be uncovered and replaced with the correct information.
- the information is the name and / or type of the corresponding subscriber and / or the network address and / or configuration parameters and / or configuration information of the corresponding subscriber which is replaced by the first subscriber and / or or it is information regarding the tasks that the new subscriber must take on the network for the old subscriber.
- the network is a network for an automation system.
- the invention relates to a computer program product having computer-executable instructions for Execution of the inventive method described above on at least the second participant.
- the computer program may be brokers installed on the multiple users of the network.
