Part 2: Software tool requirements
FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61499-2 has been prepared by IEC technical committee 65: Industrial-process measurement and control. This standard cancels and replaces IEC/PAS 61499-2 published in 2001. This first edition constitutes a technical revision. The following major technical changes have occurred between the PAS edition and this edition: a) Syntax for network segments, links and parameters has been added in Annex A for consistency with IEC 61499-1. b) Syntax for parameters instead of constant data connections has been included for consistency with IEC 61499-1.

4 Software tool requirements 4.1 Information to be provided by the software tool supplier This Clause defines the functional 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: a) The type or types of library element to which the software tool applies. b) 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. 4.2 Exchange of library elements A software tool shall be capable of exchanging its 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. 4.3 Information to be provided by the supplier of library elements NOTE The provisions of this subclause 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 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 implementation 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 device of Class 2 as described in IEC 61499-4, for instance using an XML syntax which may be defined in a compliance profile developed according to the rules given in IEC 61499-4. 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 element. 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 and data interfaces as defined in IEC 61499-1, 5.2.1, and its services as defined in IEC 61499-1, 6.1.3; • resource type and device type library elements showing the occurrence and connections of the function block instances.

– 8 – 61499-2  IEC:2005(E) 4.4 Display of declarations A software tool shall be capable of displaying the declarations of its associated library elements in a form appropriate 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 as its algorithms and the control of their execution, for example via
an execution control chart (ECC), etc. 4.5 Modification of declarations A software tool shall enable its user to modify the declarations of its associated library elements as appropriate to the engineering task. Such modifications may include adding, deleting or changing the contents of declarations, and may be performed either graphically or textually or both. 4.6 Validation of declarations If required by the associated engineering task, a software tool shall provide facilities for validation of the declarations of its associated library elements. Such facilities may include, but are not limited to: a) Checking the correctness of the syntax of declarations. b) Checking the semantic correctness of declarations, for instance, checking whether all function block instances in an application and its associated subapplications are properly allocated to resources, interconnected within resources, and intercommunicating among resources in a system configuration. c) 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 or different types. 4.7 Implementation of declarations If 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: a) The production of executable code ("firmware") for embedding in instances of resource types and device types. b) The creation and interconnection ("downloading") of function block instances in resources and devices, for instance by using the management facilities defined in subclause 3.3 and Annexes F and G of IEC 61499-1. 4.8 System operation, testing and maintenance If 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: a) The facilities described in preceding subclauses of this Clause. b) The information exchange facilities defined in subclause 6.2 and Annex F of IEC 61499-1.
