23、4: Rules for compliance profiles BS EN 61499-2:2013 6 61499-2 IEC:2012 FUNCTION BLOCKS Part 2: Software tool requirements 1 Scope This part of IEC 61499 defines requirements for software tools to support the following systems engineering tasks enumerated in IEC 61499-1: the specification of function
24、 block types; the functional specification of resource types and device types; the specification, analysis, and validation of distributed IPMCSs; the configuration, implementation, operation, and maintenance of distributed IPMCSs; the exchange of information among software tools. It is assumed that
25、such software tools may be used in the context of an Engineering Support System (ESS) as described in IEC 61499-1. It is beyond the scope of this standard to specify the entire life cycle of industrial-process measurement and control systems (IPMCSs), or the entire set of tasks and activities requir
26、ed to support an IPCMS over its life cycle. However, other standards which do specify such tasks and activities may extend or modify the requirements specified in this part of IEC 61499. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document
27、and are indispensable for its application. For dated references, only the edition cited applies.

29、s applying to a data type, function block type, adapter type, subapplication type, resource type, device type, segment type, or system configuration BS EN 61499-2:201361499-2 IEC:2012 7 4 Software tool requirements Information to be provided by the software tool supplier 4.1This Clause defines the f
30、unctional requirements of software tools that support the performance of the systems engineering tasks enumerated in Clause 1. The supplier of a software tool shall specify the following information in addition to other information required in this Clause: the type or types of library element to whi
31、ch the software tool applies; the engineering task or tasks supported by the software tool. Task descriptions may be taken from the enumeration of engineering tasks given in Clause 1, or may be defined by the supplier. Exchange of library elements 4.2A software tool shall be capable of exchanging it
32、s library elements with other software tools. This exchange shall take the form of data in the format defined in Annex A, written on physical media or exchanged over communication links or networks. Information to be provided by the supplier of library elements 4.3NOTE The provisions of this subclau
33、se are intended to provide the means by which the provider of a library element may achieve protection of intellectual property while still providing sufficient information to permit the effective use of the library element. The provider of a library element may elect to provide an implementation of
34、 the library element. EXAMPLE 1 The provider of a function block type library element may provide an implementation of the function block type as: one or more instances of the function block type in a resource contained in a device of Class 0 or higher as described in IEC 61499-4; an instantiable im
35、plementation of the function block type in a resource contained in a device of Class 1 or higher as described in IEC 61499-4; a file in an implementation-dependent format suitable for installation in a resource contained in a deviceof Class 2 as described in IEC 61499-4, for instance using the XML s
36、yntax defined in Annex D. When an implementation of a library element is provided, the provider is not required to provide full details of the implementation. However, the provider shall provide sufficient information to enable the user to fully determine the functionality of the provided library el
37、ement. EXAMPLE 2 The requirement of the above paragraph would be met by the provider of an instance of a function block type in a resource through the provision, at a minimum, of the following information: a function block type library element specifying its event interfaces, data interfaces and ser
38、vices as defined in IEC 61499-1; resource type and device type library elements showing the occurrence and connections of the function block instances. Display of declarations 4.4A software tool shall be capable of displaying the declarations of its associated library elements in a form appropriate
39、to the engineering task. This display may utilize the graphical or textual formats defined in IEC 61499-1, or a format defined by the supplier of the software tool. NOTE The declarations of a library element may define its interfaces (event and data inputs and outputs) and internal variables as well
40、 as its algorithms and the control of their execution, for example via an execution control chart (ECC), etc. BS EN 61499-2:2013 8 61499-2 IEC:2012 Software tools may provide additional features, beyond those illustrated in IEC 61499-1, in the graphic display of declarations. EXAMPLE 1 In the displa
41、y of an Execution Control Chart (ECC), the tool may provide, along with the display of each transition, a cardinal number indicating the order (as defined in IEC 61499-1) in which the transition is evaluated. EXAMPLE 2 A software tool may provide means of navigating a mapping from the display of a f
42、unction block instance in an application to its corresponding display in a resource, and vice versa. Modification of declarations 4.5A software tool shall enable its user to modify the declarations of its associated library elements as appropriate to the engineering task. Such modifications may incl
43、ude adding, deleting or changing the contents of declarations, and may be performed either graphically or textually or both. EXAMPLE The software tool may provide convenient means for the user to change the order in which declarations are listed in their textual representation, for instance in a lis
44、t of transitions in an Execution Control Chart (ECC), without the user having to edit the textual representation by manual means such as “cut and paste“. Validation of declarations 4.6If required by the associated engineering task, a software tool shall provide facilities for validation of the decla
45、rations of its associated library elements. Such facilities may include, but are not limited to: Checking the corectness of the syntax of declarations. Checking the semantic corectness of declarations, for instance, checking whether al function block instances in an application and its associated su
46、bapplications are properly allocated to resources, interconnected within resources, and intercommunicating among resources in a system configuration. Simulation and testing of the operation of an instance of a library element type, either by itself or in association with other instances of the same
47、or different types. Implementation of declarations 4.7If required by the associated engineering task, a software tool shall provide facilities for the implementation of the declarations of its associated library elements. Such facilities may include, but are not limited to: the production of an exec
48、utable code (“firmware“) for embedding in instances of resource types and device types; the creation and interconnection (“downloading“) of function block instances in resources and devices, for instance by using the management facilities defined in subclause 6.3 and Annexes F and G of IEC 61499-1.
49、System operation, testing and maintenance 4.8If required by the associated engineering task, a software tool shall provide facilities for the operation, testing and maintenance of an Industrial Process Measurement and Control System (IPMCS) specified by its associated library elements. Such facilities may include, but are not limited to: the facilities described in preceding subclauses of this Clause; the information exchange facilities defined in IEC 61499-1. BS E
