- the fixed transmission method ie the fixed protocol
- the fixed protocol is advantageously replaced by a flexibly agreed protocol, so that data provision components and data consumption components each have one for the respective purpose of Transfer of subscription data can agree on a suitable protocol.
- the protocol can advantageously be set dynamically for each individual subscription, particularly at runtime.
- a suitable protocol can be determined, for example, with regard to the highest possible utilization of data consumption component (s) and / or data supply component (s) and / or transmission capacity of a data transmission channel connecting a data supply component and a data consumption component.

- FIG. 2 shows a diagrammatic representation of a transmission of process data from a data provision component to a data consumption component of the network according to FIG. 1 in a schematic outline.
- the local network 10 shown in FIG. 1 comprises a plurality of field devices 20 in an automated manufacturing plant FA.
- a local network 10 in the sense of this invention it denotes a network 10 which is spatially limited to the manufacturing plant FA.
- the manufacturing plant FA has, on the one hand, stationary industrial motors IM and, on the other hand, industrial robots IR, which each implement steps of a manufacturing process implemented with the manufacturing plant FA.
- the industrial robots IR can also carry out steps in a work process.
- the field devices 20 include sensors which are arranged on the stationary industrial motors IM and which are each designed as temperature sensors for detecting a temperature of the respective industrial motor IM on which they are arranged and / or as a tachometer for detecting a speed of the respective industrial engine IM on which they are arranged are formed.

- the field devices 20 in further exemplary embodiments not shown separately can also have or be other sensors arranged on a system or machine.
- the field devices 20 are signal-connected for communication with edge devices 30.
- Edge devices 30 in the sense of the present invention refer to gateways which mediate between Feldgerä th 20 and a non-local network C and to avoid latencies and to save data transmission resources process part of the data of the field devices 20 independently and only the remaining part of this data forward to the non-local network C.
- edge devices 30 are arranged on the industrial motors IM and on the industrial robots IR.
- edge devices 30 can alternatively or additionally be arranged in other areas within the production plant FA, for example stationary in part of the production plant.
- the non-local network C in the context of this invention is formed, for example, with a cloud network.
- the non-local network C can alternatively or additionally be formed with one or more servers.
- the non-local network C can be replaced by a completely or partially local network.
- the field devices 20 consequently represent data provision components DP of the local network 10, while the edge devices 30 form data consumers DC of the local network 10.
- the local network 10 optionally forms an industrial Internet of Things in the exemplary embodiment shown.
- the local network 10 in particular forms a non-hierarchical and self-configuring network in which there is no predefined assignment of a field device 20 to an edge device 30, but a field device 20 can be added to the local network 10 and field device 20 and Edge devices 30 independently establish a signal connection, preferably a wireless connection and / or Internet connection, with one another.
- the signal connection between field device 20 and edge device 30 is data-specific, i.e. different assignments of field device 20 and edge device 30 can be established and basically exist in parallel with one another with regard to different technical data to be transmitted.
- a field device 20 it is conceivable for a field device 20 to have both a tachometer and a temperature sensor, with data from the tachometer being transmitted to a first edge device 30 and temperature data being transmitted to a second edge device 30.
- a data-specific transmission takes place by means of an intermediary publication / subscription service.
- edge devices 30 set up, as data consumption components DC, subscriptions to specific subscription data DAT from the field devices 20, for example subscriptions to speed data, from the data supply components DP. This is done by means of the method according to the invention for the transmission of subscription data DAT:
- the data consumption components DC make their subscriptions known to all data provision components DP by means of broadcast and / or multicast messages MCMCN.
- the broadcast and / or multicast messages MCMCN are sent by means of a uniform protocol specified by the publication / subscription service transmitted from the data consumption components DC to the data consumption components DP.
- the broadcast and / or multicast messages MCMCN contain, on the one hand, in a manner known per se, the respective subscription information ABO, which specifies the data to be transmitted, here for example speed data.
- the broadcast and / or multicast messages MCMCN also contain a protocol identifier PKE which identifies the protocols for the transmission of the subscription data DAT that can be processed, i.e. received, by the data consumption component DC.
- the protocol identifier PKE identifies at least one protocol.
- the protocol identifier PKE identifies at least two protocols by means of which the data consumption component can receive the subscription data DAT.
- such protocols can be connectionless protocols which have low latency but do not necessarily require complete data transmission, such as a real-time transport protocol (RTP), and / or connection-oriented protocols in which complete data transmission is carried out is ensured.
- RTP real-time transport protocol
- one or more of the at least two protocols are a Profibus and / or OPC-UA and / or BACnet and / or Modbus and / or ZigBee protocol.
- the protocol identifier PKE also contains an optional weighting, which contains a preference of a protocol flagged by the protocol identifier, for example with regard to a connection-oriented or connectionless protocol or, for example, with regard to one or more preferred special protocols.
- the charge status data in the present case should be recorded as completely as possible in terms of time in order to be able to predict the operating time of an energy store of the industrial robots IR and thus a required charge of the energy store as precisely as possible and, accordingly, an adjustment that is as smooth as possible planning the production process of the FA production facility in advance.
- connection-oriented, real-time-capable protocol is preferred, since time-synchronous monitoring of the speed of the industrial motor IM and the temperature of the industrial motor IM for possible anomalies in the operation of the industrial motor IM can point out. Consequently, a connection-oriented protocol makes it possible, if necessary, to be able to make necessary adjustments to the operation of the industrial motor IM in a timely manner and, if necessary, to avoid a failure of the industrial motor IM.
- other weightings can also be included in the protocol identifiers PKE as an alternative or in addition.
- the data provision component DP now selects one of the protocols identified in the protocol identifier PKE, which is available for the data provision component DP, for the transmission of the subscription data DAT. That protocol is selected which is available for the data provision component DP and which has the highest weighting for the given subscription.
- the connection information required in addition to the transmission of the subscription data DAT for example IP address and port, are contained in the illustrated embodiment in the protocol identifier PKE. This connection information can, however, also be contained in the subscription information ABO in further exemplary embodiments that are not specifically shown. In FIG. 2, only a single pair of a data consumption component DC and a data provision component DP is shown.
- the local network 10 forms an inventive network according to the invention.
- the data consumption components DC and the data provision components DP each form data consumption components DC according to the invention and data provision components DP according to the invention.
- the production system FA described above and shown in the drawing represents a system according to the invention.
- a production plant FA there can only be a single machine, for example a single industrial robot IR, on which the local network includes one or more edge devices 30 and several field devices 20 on this single industrial robot IR.
- the data provision components DP do not transmit any subscription data DAT if the data consumption components DC do not identify any protocols that the data provision components DP can use for transmission.
- a fallback or standard protocol which supports all functional components of the local network, ie all edge devices 30 and all field devices 20. If no protocol can therefore be agreed between the data provision component DP and the data consumption component DC from the protocol identifier PKE, the fallback or standard protocol is selected instead for communication. In exemplary embodiments which do not provide for a fallback or standard protocol, if certain pairings of edge device 30 and field device 20 do not support a common protocol, subscription data DAT cannot be transmitted from field device 20 to edge device 30.
- field devices 20 and edge devices 30 are not necessarily strictly separate functional components of the subscription / subscription service, but an edge device 30 takes on the function of an edge device 30 with regard to a certain subscription, for others Subscriptions, on the other hand, assumes the function of a field device 20.
