Description:
RELATED APPLICATIONS 
       [0001]    This application claims priority as a continuation application under 35 U.S.C. §120 to PCT/IB2007/053636 filed as an International Application on Sep. 10, 2007 designating the U.S., the entire content of which is hereby incorporated by reference in its entirety. 
     
    
     FIELD 
       [0002]    The present disclosure relates to a system configuration, and more particularly, to a configuration system of an intelligent electronic device (IED) for power transmission and distribution. 
       BACKGROUND INFORMATION 
       [0003]    An object of configuring an IED is to make and modify a complete configuration from the input of the device to the output of the device. An IED is a control and protection device for power transmission and distribution, such as a protective relay. A configuring process begins with determining the hardware (HW) configuration by selecting hardware components from a provided list. Known HW configuration tools are, for example, CAP 501/505/531 tools by ABB Technology AG. 
         [0004]      FIG. 1  illustrates a prior art system for configuring an intelligent electronic device. The user of the system starts the configuration of an IED with an HW configuration tool and selects the required components which are to be used in an IED housing. The housing has a specific layout and is a container of hardware modules  102 . The housing must be populated with hardware modules  102  according to the rules provided by the selected housing type. This results in a certain HW configuration whose operation is modified with other configuration tools such as an application configuration tool (ACT)  10  and a signal matrix tool  20  (SMT). 
         [0005]    The ACT  10  is a graphical configuration tool providing an IED application by using function blocks  104 . The ACT  10  has the advantage of visualizing and documenting the functionality of the device, but has the disadvantage of connecting and disconnecting inputs during testing and commissioning and reconnecting them to the same place. This is because the connections between the function blocks  102  and the actual hardware modules  104  are not provided. A connection to the hardware modules  104  is provided by a cross-reference list, which uses interface variables to connect signals between the hardware modules  102  and the function blocks  104 . 
         [0006]    The SMT  20  is a table-based configuration tool. The purpose of the SMT  20  is to handle signals of inputs and outputs toward the function blocks  104  and between the function blocks  104  on a matrix-based principle. This table-based configuration tool allows the user to use predefined logical functions (such as AND, OR) for the signals. A disadvantage of the table-based configuration tool is the difficulty of visualizing the configuration of the device on a SMT display, because the table of the SMT  20  is actually provided by a cross-reference list using interface variables to connect signals between the function blocks  102  and the actual inputs and outputs of the hardware modules  104 . An advantage of SMT  20  is that it allows the user to connect and disconnect the signal and trip the output signal during testing and commissioning. 
         [0007]    One disadvantage associated with the above system is that the ACT  10  cannot be effectively used as an on-line testing tool. 
         [0008]    Another disadvantage associated with the above system is that the user has to choose which configuration tool he/she is going to use during the configuration of the IED. The configuration tool has to be closed when the user wishes to use another configuration tool. 
         [0009]    One disadvantage of the current configuring systems is that the user has to start the configuration process from the beginning of the configuration process if there is a need to change the HW configuration and, as a result, the configurations made by other configuring tools is lost. 
       SUMMARY 
       [0010]    An exemplary embodiment provides a computer-readable storage medium having a configuration software tool comprised of computer-executable instructions stored thereon to cause a computing device to provide a plurality of function blocks and connections between function blocks in a visual representation of configuration data of an intelligent electronic device. Each function block is for executing a function in the intelligent electronic device.

     DETAILED DESCRIPTION 
       [0022]    Exemplary embodiments of the present disclosure to provide a configuration system that alleviates the above-described disadvantages. 
         [0023]    Exemplary embodiments of the present disclosure provide an advantageous technique in which all configuration data from the input of the device to the output of the device is made available for different tools by data storage and a configuration data server. Different configuration tools can also be used coexistent. This is achieved by updating the configuration data with a configuration data server administering the data in different configuring tools so that everything that is configured in one configuration tool will be automatically updated in the other configuring tools. Therefore, there is no need for a cross-reference list using interface variables, because different configuration tools use and modify the same configuration data, that is updated in other tools. 
         [0024]    An advantage of the present disclosure to the user is that the application configuration tool (ACT) can be even used as an on-line testing tool, because the signal flow from the input of the device to the output of the device is retrieved and arranged visibly and modifiably. 
         [0025]    Another advantage of the present disclosure to the user is that the application configuration tool (ACT) and the signal matrix tool (SMT) or other configuring tools can be viewed and used concurrently. 
         [0026]      FIG. 2  illustrates an exemplary system for configuring an IED according to at least one embodiment. As illustrated in  FIG. 2 , the signal flow from the input of the device to the output of the device is visible in the application configuration tool (ACT)  10 . All connections between any element is therefore modifiable from the ACT  10 . This is because the configuration data is made available to all tools and all changes made by any tool will be updated in all tools. The amount of information shown by different tools is controlled by the configuration data server for clarity reasons. For example, some of the data is not shown to the user in the signal matrix tool  20  (SMT). This allows the user to choose between the ACT  10  and the SMT  20  when connecting/disconnecting internal functions to/from the real inputs and outputs of the device. 
         [0027]      FIG. 3  illustrates a data server concept according to an exemplary embodiment of the present disclosure. A configuration data server (CDS) is responsible for the business logic and for combining the type and instance data. One data server can serve one or several tool components with logic and data. For example, according to an exemplary embodiment, the configuration data server  2  is responsible for managing the configuration data for configuration tools such as ACT  10 , SMT  20  and HW (hardware) tool  30  (hereinafter “HWtool”). Data servers can also exchange data with each other when needed. The configuration data server  2  can be connected to a second data server, which is a parameter data server  5 , for example. According to an exemplary embodiment, the same data should not be stored by more than one data server. 
         [0028]      FIG. 4  shows various types of data that can be administered by the configuration data server  2 . Configuration data relates to connections, signals, functions and hardware (HW) of the IED, for example. Data administered by the configuration data server  2  is used in configuration tools such as the ACT  10 , SMT  20  and HWtool  30 . In other words, the ACT  10 , SMT  20  and HWtool  30  can update the data in the same server. There can be more than one data server, which store other IED-related data. Instance and type identifiers for connecting data can be stored in every data server. Instance and type identifiers can be used as relation identifiers. 
         [0029]      FIG. 5  is a block diagram illustrating an exemplary relationship between data servers and data storage. The configuration data server  2 , for the ACT  10 , SMT  20  and HW  30 , stores data in a configuration data server data storage (CDS DB)  11 , which can be a SQL-database (structured query language) or an XML-type data storage, for example. Among other servers shown, the parameter data server  5  and the project data server (PDS)  4  can have a common data storage, such as a project database (Project DB)  12 , for example. All data to the ACT  10 , SMT  20  and HW  30  can be tunnelled through the configuration data server  2 . 
         [0030]      FIG. 6  is an illustrative partial diagram showing an example in which the user can add a function in the ACT  10 . The exemplary system can implement the following features. For example, the ACT  10  can call “CreateFunction” in the CDS  2 . In this example, the CDS  2  calls CreateObject in the PDS  4 . Open tools (SMT  20 ) are notified by the CDS  2  that new data exists. Methods providing coexistence of the data are created in the CDS  2  with Object Oriented Programming. CDS  2  has an interface that provides a CDS object model; instance and type data. The interface has a method of checking if the configuration tool has unsaved instance data. One exemplary technique is to register/unregister the configuration tool as a listener of CDS. One possibility is to synchronize all the registered listeners when the configuration tool saves the configuration data. The interface manages one-directional connections from the source object to multiple target objects. 
         [0031]      FIG. 7  is an illustrative diagram showing an example in which the user adds a function in the ACT  10 . The system can implement the following features. For example, the ACT  10  calls “CreateFunction” in the CDS  2 . The CDS  2  calls CreateObject in the PDS  4 . The Open tool (SMT  20 ) is notified by the CDS  2  that new data exists. Data server(s) (e.g., CDS  2 , PDS  4 ) receive(s) type information on the added function from the type information stored in one of the servers. Relationships between the data stores are handled by the data servers. Other data servers and open tools are notified by firing a CreateObject event. Only CreateObject methods are shown here but the exemplary features are similar in deleting a function (DeleteObject) (the example shown in  FIG. 8 ) and in modifying a function (ModifyObject). 
         [0032]      FIG. 8  is an illustrative diagram showing an example in which the user deletes a function in the ACT  10 . The system can implement the following features. For example, the ACT  10  calls “DeleteObject” in the CDS  2 . The CDS  2  calls DeleteObject in the PDS  4 . Other open tools (SMT  20 ) are notified by the CDS  2  that data no longer exists. Other servers remove all references to the deleted object. 
         [0033]      FIG. 9  illustrates an exemplary situation in which the user adds a hardware in the HWtool  30 . The system can implement the following features. For example, the HWtool  30  calls “CreatObject” in the CDS  2 . The CDS  2  calls CreateObject in the PDS  4 . The open tools (ACT  10  and SMT  20 ) are notified by CDS  2  that new data exists. The PDS  4  notifies the PST and the plant structure, which is updated when the user saves the changes. 
         [0034]    Although the exemplary embodiments of the present disclosure described with reference to the drawings comprise a computer apparatus having a processor (e.g., CPU) and a process performed in the computer apparatus and the system, the disclosure also extends to computer programs, such as computer programs recorded on a computer-readable recording medium that cause a computing device, when executing the program to be adapted for carrying out the exemplary embodiments of the present disclosure. The program may be in the form of source code, an object code, a code intermediate source, and an object code such as in a partially compiled form, or in any other form suitable for use in implementation of the processes according to the disclosure. The program may be recorded in a computer-readable storage medium, such as a storage medium or a magnetic recording medium. 
         [0035]    It will be appreciated that, as the technology advances, the inventive concept of the present disclosure can be implemented in various ways. The disclosure and its embodiments are not limited to the examples described above but may vary within the scope of the claims. 
         [0036]    It will be appreciated by those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The presently disclosed embodiments are therefore considered in all respects to be illustrative and not restricted. The scope of the invention is indicated by the appended claims rather than the foregoing description and all changes that come within the meaning and range and equivalence thereof are intended to be embraced therein.
