Legal informationWarning notice systemThis manual contains notices you have to observe in order to ensure your personal safety, as well as to preventdamage to property. The notices referring to your personal safety are highlighted in the manual by a safety alertsymbol, notices referring only to property damage have no safety alert symbol. These notices shown below aregraded according to the degree of danger.DANGERindicates that death or severe personal injury will result if proper precautions are not taken.WARNINGindicates that death or severe personal injury may result if proper precautions are not taken.CAUTIONindicates that minor personal injury can result if proper precautions are not taken.NOTICEindicates that property damage can result if proper precautions are not taken.If more than one degree of danger is present, the warning notice representing the highest degree of danger willbe used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating toproperty damage.Qualified PersonnelThe product/system described in this documentation may be operated only by personnel qualified for the specifictask in accordance with the relevant documentation, in particular its warning notices and safety instructions.Qualified personnel are those who, based on their training and experience, are capable of identifying risks andavoiding potential hazards when working with these products/systems.Proper use of Siemens productsNote the following:WARNINGSiemens products may only be used for the applications described in the catalog and in the relevant technicaldocumentation. If products and components from other manufacturers are used, these must be recommendedor approved by Siemens. Proper transport, storage, installation, assembly, commissioning, operation andmaintenance are required to ensure that the products operate safely and without any problems.

Introduction1The IEC61131 standard is applicable for the programmable logic controllers (PLC).In accordance with the rules of the European Union, this international standard has beenaccepted in Germany as DIN EN 61131, in France as NF EN 61131, and in Britain asBS EN 61131.The most important parts of the standard are quoted below. Quotes are in italics.Part 3 of this standard defines the "Area of application" in Section 1.“This Part of IEC 61131 specifies syntax and semantics of programming languages forprogrammable controllers as defined in Part 1 of the IEC 61131.The functions of program entry, testing, monitoring, operating system, etc., are specified inPart 1.This part of IEC 61131 specifies the syntax and semantics of a unified suite of programminglanguages for PLCs. These consist of textual languages, IL (Instruction List) and ST(Structured Text), and two graphical languages, LD (Ladder Diagram) and FBD (FunctionBlock Diagram).Sequential Function Chart (SFC) elements are defined for structuring the internalorganization of programmable controller programs and function blocks. Also, configurationelements are defined which support the installation of programmable controller programs intoprogrammable controller systems."The programming language elements defined in this part may be used in an interactiveprogramming environment. The specification of such environments is beyond the scope ofthis standard; however, such an environment shall be capable of producing textual orgraphic program documentation in the formats specified in this part.Section 5 "Standards compliance" specifies:"A programmable controller system, as defined in IEC 61131-1, which claims to comply,wholly or partially, with the requirements of this Part of IEC 61131 shall do so only asdescribed below: “Standards compliance according to IEC 61131-3 (3rd Edition)Function Manual, 04/2015, A5E35932122-AA5
IntroductionSection 5.3 "Compliance declaration of the manufacturer" specifies:"The manufacturer may define any consistent subset of characteristics that are listed in thecharacteristic tables, and must make known the available subset in the "Compliancedeclaration of the manufacturer".The compliance declaration of the manufacturer must be contained in the documentationthat is included with the system, or it must be generated by the system itself.The format of the compliance declaration of the manufacturer must provide the followinginformation. Figure 4 in the standard shows an example. The general information shall include the name and address of the manufacturer, thename and version of the product, the type and version of the controller and the revisiondate. The number of the corresponding characteristics table, the characteristics number andthe applicable programming language must be specified for each implementedcharacteristic. The title and subtitle of the characteristics table, the description of the characteristic,examples, manufacturers remarks etc. are optional.Table and characteristics that are not implemented can be omitted."Standards compliance according to IEC 61131-3 (3rd Edition)6Function Manual, 04/2015, A5E35932122-AA
