Definitions

  • the invention relates to a method, a system and a transmitting / receiving device for transmitting data via a data transmission device.
  • the amount of data to be transmitted increases and the structure of the information to be transmitted becomes increasingly complex, so that special data structures with a complex structure have to be transmitted between the computers or the automation components or field devices. It is important that the data structures can be checked for consistency between the participating senders and recipients of the data. Efficient data transmission should of course also be guaranteed.
  • US Pat. No. 6,363,428 discloses a method and a device for the separate transmission of connection identification and content data via a serial bus network.
  • the object of the present invention is now to specify a method, a system and a transmitting / receiving device which enable more efficient data transmission.
  • the object is achieved by a method for transmitting data between transmission / reception devices via a data exchange device, in which information on the structure of the data to be transmitted is exchanged between the transmission / reception devices in an establishment phase, a comparison of the structure of the data to be transmitted between the transmitting / receiving devices takes place, the data is sent in a productive phase and is assigned to the structure when it is received.
  • the object is achieved by a system for transmitting data between transmitting / receiving devices via a data exchange device, with first means for exchanging information on the structure of the data to be transmitted between the transmitting / receiving devices in one
  • Establishment phase second means for comparing the structure of the data to be transmitted between the transmitting / receiving devices, third means for sending the data in a productive phase and fourth means for assigning the data to the structure after receiving the data.
  • a transmitting / receiving device for transmitting data via a data exchange device with first means for exchanging information on the structure of the data to be transmitted with at least one further transmitting / receiving device in an establishment phase, second means for comparing the structure of the data to be transmitted with the further transmitting / receiving device, third means for transmitting the data in a productive phase and fourth means for assigning the data to the structure after receiving the data.
  • the invention is based on the knowledge that, with the amounts of data to be transmitted nowadays, which generally obey a complex data structure, efficient and also consistent data transmission is made possible if the data structure description is separate from the actual productive data can be transferred.
  • the data structure that corresponds to the data to be transmitted later is first sent from one transceiver to another transceiver. If the data structure sent corresponds to a defined form on both the sender and receiver side, which is accepted by the sender and receiver, the actual data can be transmitted. The consistency of the structural information can thus be checked in advance. The actual data are then sent via the data exchange device. This avoids the transport of data with full detailed structure information, which would normally not be efficient. However, if the data were to be sent without any detailed structure information, this could lead to problems with ensuring consistency.
  • both information namely the detailed structure information and the subsequent productive data
  • the received data only need to be reassigned to the corresponding detailed structure information so that the semantics contained in the data can be interpreted correctly.
  • the gain in efficiency in such a data transmission is particularly great when data with a certain structure are frequently exchanged between the transmitting / receiving devices. This is the case, for example, in the case of a cyclical data transmission at regular time intervals or a cyclical transmission when the value changes within a cycle.
  • Another advantageous embodiment of the invention is characterized in that the data is transmitted via a network.
  • the standard systems that are currently used for the transmission of data can be used in this way by the method presented.
  • Networks for data transmission between individual automation components such as controllers or field devices are used especially in the field of industrial automation. These networks are, for example, the so-called Industrial Ethernet. Individual automation components connected to the Ethernet can easily send their data to other automation components involved via the Ethernet using the method presented. The use of an already established network standard is therefore possible in the context of this advantageous development of the method and system according to the invention.
  • Another advantageous embodiment of the invention is characterized in that the data are transmitted in the form of data packets.
  • a further increase in efficiency can be achieved in the transmission of the structure contents, that is to say the actual data, since the data can be transmitted in a packed form, that is to say compressed and thus saving space.
  • this design according to the invention enables the existing network capacities to be used efficiently without the need for costly expansions to increase the transmission capacities.
  • a further advantageous embodiment of the invention is characterized in that the structure of the data to be transmitted is predetermined by the transmitting and / or the receiving transceiver.
  • This embodiment of the invention is advantageous because a specification of the side from which the initiative or the emitter or receiver originates is irrelevant.
  • Each participant connected to the network that is to say each transmitting / receiving device, is thereby able to have one Specify structure definition and then transfer the productive data to other recipients.
  • the structure definition is checked for consistency among the send / receive devices involved and, if the data structure is suitable, a transfer then takes place.
  • a complex assignment of “rights for the definition of structural information can be avoided by this embodiment of the invention.
  • the method or system presented can thus be established in a simple manner.
  • a further advantageous embodiment of the invention is characterized in that a connection identifier is sent between the transmitting / receiving devices. If detailed structure information is received from a transmitting / receiving device connected to the network and it is determined by this transmitting / receiving device that the detailed structure information is consistent with its own structure definition, then a reply to the transmitted structural information can be sent to the Senders.
  • the recipient of the connection identifier that is to say the original sender of the detailed structure information, thus knows that the actual data can now be sent, and the productive data are sent together with the connection identifier. On the basis of this connection identifier, the recipient can then easily assign the productive or net data to the corresponding structure definition. This ensures a consistent and efficient transfer of data.
  • Another advantageous embodiment of the invention is characterized in that the data is transmitted via an Internet. If the transmitting / receiving devices involved are not all connected to an Ethernet or bus system, but instead a data transmission takes place between them, for example in the case of production distributed over several locations, this can likewise be carried out consistently and efficiently in the context of the system according to the invention be handled. It is advantageous here that not all of the transmitting / receiving devices have to be connected to one another in terms of hardware. Data can be sent between multiple locations. This is advantageous, for example, if the production processes of different locations are to be visualized in a central place on an operator control and monitoring system.
  • a further alternative or additional advantageous embodiment is the use in connection with a central system information system in which the data arising in the production process are managed and archived in a central data store.
  • Data from the various production locations for example via controls, field devices, sensors and any other automation components, can be collected and stored at a central location.
  • it is particularly advantageous to ensure efficient data transmission since the central summary of the information from the production level results in large amounts of data to be transmitted.
  • 1 shows a system for transmitting data.
  • a system is shown in FIG. 1, in which transmission / reception devices 1, 2 exchange data with one another via a data transmission device 3.
  • the transmitting / receiving devices 1, 2 can be any computer.
  • an automation component for example in an automation system for an industrial production process, can be represented by a corresponding transmission / reception device 1, 2.
  • the number of transmitting / receiving devices 1, 2 involved is not limited to the examples shown in FIG. 1. Rather, there can be further transmission / reception devices 1, 2 on the data transmission participate.
  • a first phase of the establishment of the data transmission detailed structure information is transmitted between the transmitting / receiving devices. This is information about the actual structure of the data to be subsequently transmitted.
  • the detailed structure information is transmitted and compared between the transmitting / receiving devices 1, 2 involved. If the structure definitions match, a connection identifier is sent in response to the corresponding request. In the subsequent productive phase, the connection identifier sent is sent together with the net data or productive data to be transmitted.
  • the recipient of the data can use the connection identifier to assign the incoming net data or productive data to a structure definition available to him. By assigning the data to the structure again, the recipient can extract the actual information content from the data.
  • the invention relates to a method, a system and a transmitting / receiving device for transmitting data via a data transmission device.
  • Information on the structure of the data to be transmitted is exchanged between two or more transmitting / receiving devices in an establishment phase.
  • the structure of the data to be transmitted is then compared between the transmitting / receiving devices, and if they match, the data are sent in a productive phase.
  • the data are assigned to the corresponding structure by the recipient.
