Description:
FIELD 
     The invention relates to a system and a method for directed provision and installation of device-specific functionalities and/or information for field devices which are arranged in a distributed system, in particular in a distributed automation system. 
     BACKGROUND 
     The structure of a distributed system comprises a large number of field devices, which communicate via a network structure, for example via a bus system, with one another and/or with a higher-level control system or controller. Examples of field devices which are used in distributed systems are drives, motor protection units, switchgear assemblies, sensors, in particular sensors for pressure, temperature and flow measurements, low-voltage devices, actuators and/or analysis devices. 
     Device information for the field devices in the distributed system, such as device documentation, device core data and device parameters, is stored. 
     The functions of the field devices are not just restricted to passing on measurement data or fault messages. The field devices are increasingly being extended with additional functionalities for the configuration, engineering and diagnosis of an automation system, for example with control functions, setting-up functions, diagnosis functions, maintenance functions, optimization functions, alarm processing functions and/or life functions, in which case the additional functionalities must also be integrated separately in each field device. 
     A large number of applications for control, for preventative maintenance and for status recording of the distributed system, which are also known as asset optimization (installation optimization), are also closely related to the field devices and must be installed for the field devices. 
     In order to provide the functionality and all of the descriptions which are associated with it and are accessed by a field device over the entire life cycle in the distributed system, complex installation and configuration processes are required for the device-specific functionalities and/or information for the field devices, since the device-specific functionalities and/or information are/is provided separately for each field device and are transmitted to the distributed system. 
     A further disadvantage is that the device-specific functionalities and/or information for the field devices and the components associated with them are integrated individually in the distributed system. This process is highly time-consuming and is associated with considerable technical effort, thus in particular considerably increasing the setting-up effort. 
     Components which are necessary in order to address a relevant field device and use it in a given network do not yet exist on the basis of the procedure described above, but are dependent on further configuration and setting-up steps. These components differ, depending on the communication architecture that is used. Fieldbus systems such as FOUNDATION fieldbus, PROFIBUS, PROFINet and/or HART are suitable protocols for communication between the field devices and the higher-level control system or controller. Linking devices (couplers) may represent the corresponding component for the FOUNDATION fieldbus. Corresponding components are provided by remote-I/Os (remote input and output units) for the PROFIBUS. 
     SUMMARY 
     The invention is accordingly based on the object of providing an arrangement for directed provision and installation of device-specific functionalities and/or information for field devices which are arranged in a distributed system, in particular in a distributed automation system, thus avoiding the disadvantages and problems mentioned above. 
     According to the invention, this object is achieved by an arrangement having the features specified in claim  1 . A corresponding method for implementation of the arrangement according to the invention is specified in claim  17 .

     DETAILED DESCRIPTION 
       FIG. 1  shows one exemplary embodiment of the arrangement according to the invention for directed provision and installation of device-specific functionalities and/or information for field devices which are arranged in a distributed system and comprise a plurality of device-specific components  20 . 
     The device-specific components  20  relate in particular to device-specific information for drives, switchgear assemblies, instrumentation for positioning states, pressure, temperature and/or flow rate measurements, and low-voltage switching devices, as well as functionalities of the field devices over the entire life cycle of the devices for planning and configuration, for setting up, for operation, for diagnosis displays, for linking to maintenance management and for real-time displays for alarm, status and/or event messages, in particular for asset management (installation management). 
     The device-specific components  20  for this purpose interact with at least two functional units  30  which are linked to them, with the functional units  30  being used to store device information, such as device documentation and/or device core data and/or device parameters and/or device drivers, as well as control functions and/or setting-up functions and/or diagnosis functions and/or maintenance functions and/or optimization functions and/or alarm processing functions and/or life functions for integration of the field devices in the distributed system. 
     The device-specific components  20  also have means, such as device descriptions or drivers, which automatically provide and install device-specific functionalities and/or information for the field devices, which are stored in the functional units  30 . 
     The device-specific functionalities and/or information which are/is stored in the arrangement according to the invention are/is recorded as data structures and/or program components in the device-specific components  20 , such that each component has only functionalities and/or information for the device type associated with it. 
     The device-specific components  20  are extended such that it is possible to test the correctness and/or completeness of the device-specific functionalities and/or information. 
     The arrangement according to the invention can be extended by at least one configuration tool  50 , for example by a setting-up component, which assists the installation of the communication between the field devices and/or with the higher-level control system or controller. 
     Furthermore, network components  40  are integrated in the arrangement according to the invention, such as a component for a linking device, for installation of the network links for a specific communication architecture. 
     For installation that takes place automatically, the arrangement according to the invention is stored with the functionalities and/or information which are/is stored in the device-specific components  20 , the network information which is stored in the network components  40 , and the configuration instructions which are stored in the configuration tools  50 , in a memory medium  60  which can be transmitted to the field devices via the distributed system by means of a processor unit/computer unit in the higher-level control system or controller. 
     The installation of the arrangement according to the invention which is stored in the memory medium  60  can optionally be carried out with the device-specific functionalities and/or information which are/is stored in the device-specific components  20 , the network information which is stored in the network components  40  and the configuration instructions which are stored in the configuration tools  50 , by each processor unit/computer unit which is connected to the distributed system.

     The field device  70  which is used in the distributed system is normally equipped with firmware by the device manufacturer. However, further device-specific functionalities and/or information, such as device documentation, device drivers, device core data, device parameters, control functions, setting-up functions, diagnosis functions, maintenance functions, optimization functions, alarm processing functions and life functions, are required for integration of the field device  70  in the distributed system. These device-specific functionalities and/or information are/is stored in the functional units  30  of the corresponding device-specific components  20 , is or are made available by the arrangement according to the invention, and is or are transmitted to the distributed system. 
     For integration of the remote I/O and linking devices  80  in the distributed system, the arrangement according to the invention is extended by network components  40  in which the information and functionalities are stored for installation of the network links for a specific communication architecture, for example for the FOUNDATION fieldbus and/or the PROFIBUS, and/or the PROFINet and/or the HART.

     In a second step  2 , the device-specific components  20  which interact with the functional units  30  and the network components  40  carry out an installation process, which takes place automatically, such that the device-specific functionalities and/or information are/is provided and installed in a higher-level control system or controller  90  via the distributed system for the field devices  70 , in a single installation process, which takes place automatically. 
     The network components  40  are provided for installation of the network links for a specific communication architecture, for example for a fieldbus protocol in the form of PROFIBUS and/or PROFINet and/or FOUNDATION fieldbus and/or HART. 
     Once the functionalities and/or information have/has been successfully installed in the higher-level control system or controller  90 , at least one device-specific component  20  is produced in the higher-level control system or controller  90  in a step  3 . The device-specific functionalities and/or information which are/is stored in the functional units  30  are/is provided and installed in a higher-level control system or controller  90 , for example by instantiation of previously configured device-specific components  20 . 
     For the installation of the communication between the field devices  70  and/or with the higher-level control system or controller  90 , the arrangement according to the invention is extended by configuration tools  50  which, in a fourth step  4 , assist the system configuration, in particular the communication with the field devices  70  during the setting up and configuration of the field devices  70 . 
     In an alternative embodiment, the device-specific components  20 , the configuration tools  50  and/or the network components  40  can also be installed selectively for the field devices  70 . 
     In one particular embodiment of the method according to the invention, the device-specific components  20  have at least one device-specific component  20  added to them or removed from them by means of a program approach in a further step. 
       FIG. 4  shows one exemplary embodiment of the arrangement of the field devices  70  in a distributed system, in which the higher-level control system  90  is, for example, a process control system or a programmable logic controller, and communicates with the field devices  70  via linking devices  80  and remote I/O  80 .
