Definitions

  • the invention relates to a method for the implicit configuration of communication connections.
  • An automation solution usually consists of a large number of individual automation objects, which often have a high dependency of the automation object on the engineering system used. This means that automation objects from one manufacturer often require their own engineering system and cannot be used in other systems with automation objects from other manufacturers.
  • the object of the invention is to enable the configuration of communication connections within automation solutions, in particular across device boundaries.
  • the invention is based on the knowledge that previous solutions have a number of disadvantages.
  • the automation objects used in the creation of the automation solution have inputs and outputs through which they can communicate with other automation objects. These inputs and outputs can be used to determine at the time of the configuration which communication must take place at the time of the automation solution.
  • communication is configured for each device. Communication relationships between the automation Objects of the device established through so-called interconnections. An interconnection connects an output of an automation object with an input of an automation object in engineering and thus defines the communication that takes place at runtime. If cross-device communication is necessary, this must be configured using special communication blocks.
  • This solution has the following disadvantages:
  • the automation solution in engineering is successively put together through the use of automation objects.
  • the automation objects are a type of block that have a certain functionality.
  • the automation objects have inputs and outputs, with the help of which values for the calculations can be specified or the result of the calculations can be tapped.
  • the automation solution is actually created by interconnecting the corresponding inputs and outputs of the automation objects. These interconnections then define the communication that takes place on the plant at runtime.
  • the content of the communication is arbitrary. This can be data or events, for example.
  • the interconnections between the inputs and outputs of the automation objects AOl, A02, A03 and A04 are represented by lines.
  • An interconnection is an independent object that clearly defines a communication relationship between two automation objects. For this purpose, a reference to the corresponding output of an automation module is managed for the data source and a reference to the corresponding input of an automation module for the data sink.
  • the interconnection objects are also independent of the automation objects, which manifests itself in the fact that the establishment of an interconnection has no changes in the interconnected automation objects.
  • FIG. 1 shows a basic illustration for configuration using interconnections
  • FIG. 2 shows a schematic illustration for configuration of the so-called “Quality of Service (QoS)”
  • 3 shows an exemplary embodiment for assigning the automation objects to devices
  • FIG. 4 shows an exemplary representation for importing an automation solution into an automation system.
  • QoS Quality of Service
  • the automation objects are a type of block that have a certain functionality.

  • the interconnection objects are also independent of the automation objects, which manifests itself in the fact that the establishment of an interconnection does not have any changes in the interconnected automation objects. Since the automation objects are independent of devices in this step, there is no distinction between internal and cross-device communication. 2 shows a schematic representation of the configuration of the so-called "Quality of Service (QoS)".
  • QoS Quality of Service
  • the quality of service of the communication relationship can also be set for the established interconnections.
  • One example is the setting of the cycle time with which the data source is checked for changes If the cycle time is relatively long, this means that there is relatively little communication between the automation objects, so distribution to different devices is not critical since the generated network load is low.
  • the automation objects are assigned to devices.
  • the devices are representatives of real devices in the system (such as programmable logic controllers or drives) in the configuration environment.
  • the devices and the associated networks are configured separately.
  • the representatives of the devices in the configuration environment meet a uniform device model and thus form an abstraction of the real devices.
  • the assignment of the automation objects AOl and A02 to Gl and A03 and A04 to G2 means that communication between AOl and A02 and between A03 and A04 is device-internal, while the communication between AOl and A03 and A02 and A04 is cross-device.
  • Quality of Services are used to carry out a first plausibility check with regard to any real-time requirements for the automation solution.
  • FIG. 4 shows an exemplary representation for importing an automation solution into an automation system.
  • the automation solution configured so far is imported into the real system in the last step.
  • This process is called download.
  • the download is initiated from the configuration environment and is carried out for each device, more precisely the representative of the device, in the configuration environment. Every device representative knows his real counterpart in the system and can communicate with him via the communication link of the configuration environment to the system.
  • the automation objects assigned to him and the corresponding counterparts are created in the physical device for each device representative. In the case of a freely programmable device, this means that a corresponding piece of code is played into the device.
  • the corresponding runtime counterpart of the automation object is identified in the physical device.
  • the communication relationships described by the interconnections are established.
  • the addressing of the source and sink of a communication relationship is expanded by the corresponding identifier of the inputs and outputs of the runtime automation objects.
  • Such an identifier is composed of the identifiers of the physical device, the runtime automation object and the input or output.
  • This requires a common device model of the runtime environment.
  • Each device representative now shares the enriched interconnections with his physical counterpart of its automation objects with. Based on the interconnection information, each device then establishes its internal and external communication relationships. The enriched information of the interconnections is used for this.
  • An efficient implementation can take advantage of the fact that each device only needs to establish the communication relationships where it occurs as a source (or alternatively as a sink).
  • the automation objects AOl and A02 on the physical RG1 device are established as runtime automation objects RAOl and RA02 and A03 and A04 on the RG2 device as RA03 and RA04.
  • the interconnection information is enriched as described with corresponding information about the runtime environment.
  • these are the identifiers of RG1, RAOl, the output of RAOl for the source and RG2, RA03 and the input of RA03 for the sink. This information can then be used to establish the corresponding communication relationship between RAO1 on the device RG1 and RA03 on the device RG2.
