Definitions

  • the invention relates to an arrangement and a method for exchanging one or multiple engineering artifacts between a first and at least one further computer device.
  • control system engineering is used for all kinds of activities which are related to the designing, verification and validation, implementation and testing of a control system for a technical system used in these industry sectors, where the technical system may be a technical installation, an industrial plant or an industrial process.
  • the control system comprises at least one industrial control device, at least one sensor and at least one actuator, where the control device receives measurements taken by the at least one sensor from the technical system and determines based on these measurements and, if applicable, based on further information suitable actions of the at least one actuator to regulate the behaviour of the technical system.
  • Control system engineering usually requires the use of advanced control system engineering tools in the form of software products with complex functionalities, e.g. RobotStudio for programming robots, CoDeSys for programming programmable logic controllers (PLCs), Function Designer for programming ABB's AC800M controllers or Fieldbus Builder for configuring field devices. It may also involve different engineers which stepwise design and commission different domains of the industrial plant or industrial process. Hence, different engineering software may be used by different groups and persons.
  • the result of the engineering process, or in other words the output of the control system engineering tools is a plan for the automation system, in the following called automation solution or control solution.
  • the automation solution may comprise planning information about hardware, e.g.
  • automation devices control software executed on the automation devices and additional automation system related information, such as information relating to a control network infrastructure and corresponding device configurations, as well as configuration data relating to a human machine interface (HMI) of an HMI computer device.
  • the automation devices also called industrial control devices including software and configurations, as well as the HMI software and computer devices are usually installed at a customer's site, where the customer is a company operating an industrial plant from one of the above named industry sectors which purchases the control solution adapted to the operational requirements of the industrial plant.
  • libraries are used, where the library elements of which contain information about predefined and tested hardware or software components.
  • a library element may be a simple function block or a complex automation solution.
  • libraries are installed as part of a control system engineering tool and are thereby bound to the respective installation of the tool.
  • the software components from the libraries may be used by referring to them in the development or working files generated by using the engineering tool, as for example in the source code of the control application software.
  • control libraries In general, there exists a certain variety of control libraries: standard libraries, customer specific libraries, personal libraries for individual users, local libraries for local groups or organizations, regional libraries valid for specific geographic regions, vendor specific libraries, domain specific libraries etc.
  • the engineering process involves a group of different engineers and software developers which may all require access to the same kind of libraries which needs to be distributed to them by the owner of the respective library.
  • the results or intermediate results of the engineering process i.e. the control solutions including individual project data, such as source code and/or executable files of control application software, configuration data for an industrial control device, configuration data for a display device including trend configuration data etc., are shared and distributed between the members of the engineering group.
  • an engineering artifact may be a simple function block or a complex control or automation solution, a predefined hardware structure, a predefined communication infrastructure or a predefined device configuration set.
  • Engineering artifacts can be collected themselves in libraries, where they are called standard engineering artifacts, or they can represent engineering project results which are not fed back into a library, and then they are called individual engineering artifacts.
  • the term engineering artifacts represents all re-usable elements of the control system engineering.
  • the library 1 is a standard or fixed library. Accordingly, changes in the library are not allowed, and additions or new versions may only be provided by the library owner and need to be delivered and installed for each engineer individually. Since the standard library is fixed, certain customer requirements may not be met by its contents.
  • control solution 4 Apart from the standard library 1 , individual solutions which are created during engineering, indicated as control solution 4, are not shared to the other users Userl to User3 in a systematic way but only by means of individual export/import procedures, as is indicated by arrows 2. This requires user interaction. Due to the fixed library 1 and since the control solution 4 and the library 1 are bound to each other, import, export and reuse of the control solution 4 works only fine with engineers which have the same library 1 and the same version of it installed. Otherwise, the required version of the library 1 needs to be taken into account and may even fail due to version incompatibilities.
  • FIG. 2 Another known way to distribute engineering artifacts to different users is to provide permanent remote access to a reference installation of a standard library on a server, where the server belongs to the owner of the library and may be located on a customer site, on vendor site or on a third party site.
  • Fig. 2 This situation is illustrated by Fig. 2, where different users of the standard library 1 have permanent access to the installation of the library 1 via a permanent communication line 5, which can be a wireless or a wire-bound connection to the server.
  • a permanent communication line 5 can be a wireless or a wire-bound connection to the server.
  • the same communication line 5 may also be used to exchange individual engineering artifacts, such as the control solution 4, between the users via export/import procedures, where again a systematic way of exchanging the individual engineering artifacts is missing.
  • this concept still faces the drawbacks connected with the use of standard libraries.
  • An additional drawback is that in order to ensure the appropriate availability and usability of the server installation, the connection to the server needs to be permanent, reliable and should provide the necessary bandwidth.
  • FIG. 3 A variation of the solution of Fig. 2 is shown in Fig. 3, where again the standard library 1 is available on the server belonging to the library owner and the users Userl to User3 have local and permanent network access to that server.
  • the users cannot change the standard library 1 on the server, but they can copy parts of it and develop individual libraries 6 (Lib1 to Lib3) and individual engineering artifacts, such as control solution 4, for their own purpose.
  • individual libraries 6 Lib1 to Lib3
  • individual engineering artifacts such as control solution 4
  • the drawbacks of the previously described Figs. 1 and 2 are maintained and even aggravated, such as the requirement of a permanent and reliable server connection with sufficient bandwidth and the problems occurring when sharing engineering artifacts between the users, since the individual libraries 6 need to be exchanged and installed or updated each time as well.
  • the currently most advanced method of sharing engineering artifacts is a central database on a server, as depicted in Fig. 4.
  • the central database contains all engineering artifacts, i.e. all libraries, i.e. a standard library 1 provided by the library owner and individual libraries 6, as well as individual engineering artifacts, like automation solutions or control solution 4. All tools installed on the PCs of the users Userl to User3 have access to the central database, so that the sharing of the engineering artifacts becomes a natural function of the system.
  • the disadvantage of this technique is again the required permanent and reliable online access to the server including enough bandwidth for the engineering purposes.
  • a permanent online access requires precautions for ensuring safety and confidentiality of user data.
  • the problem solved by this invention is to provide an arrangement and method for exchanging engineering artifacts with which the above named drawbacks are overcome.
  • cloud based storage has become more and more popular.
  • Different vendors and their cloud storage solutions as for example DropBox, Microsoft with Live Sync, Apple with iDrive, iCIoud and Google with GDrive, provide cloud storage that allows storage of data, e.g. documents or photos, on one or more servers, where the storage servers are not individually visible to the user.
  • the user just sees "the cloud storage” as his storage medium and connects to it via an Internet based network connection.
  • the stored data is permanently synchronized with a local folder on the personal computer or computers of each user.
  • the principle of cloud storage is illustrated by Fig. 5. Each user has access to only his personally assigned space, Spacel to Space3, in the cloud storage.
  • Specific synchronization software in the following called cloud software, is installed on each individual computer device, PC1 to PC3, to permanently perform the synchronization process in the background between one or more designated folders on the respective computer device PC1 , PC2 or PC3 and the corresponding space in the cloud storage, Spacel , Space2 or Space3, respectively.
  • the synchronization is performed whenever the respective computer device has online access via communication line 7 to the cloud storage and a difference in the data exists.
