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 lEc also participate in this preparation IEC collaborates closely with the Interna- tional 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 internation consensus of opinion on the relevant subjects since each technical committee has representation from all inter- ested EC National Committees 3)EC Publications have the form of recommendations for international use and are accepted by lEC National Com mittees in that sense. While all reasona ble efforts are made to ensure that the technical content of ec Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinter- pretation by any end user 4)In order to promote international uniformity, IEC National Committees undertake to apply lEc Publications transparently to the maximum extent possible in their national and regional publications. Any divergence be tween any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter 5)EC itself does not provide attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies 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 ex penses arising out of the publication, use of, or reliance upon, this IEc Publication or any other IEC Publica 8)Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is dispensable for the correct application of this publication D)Attention is drawn to the possi bility 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 61131-3 has been prepared by subcommittee 65B: Measurement and control devices, of iEc technical committee 65: Industrial-process measurement, control and automation This third edition of IEC 61131-3 cancels and replaces the second edition, published in 2003 This edition constitutes a technical revision This edition includes the following significant technical changes with respect to the previous edition This third edition is a compatible extension of the second edition. The main extensions are features of classes and function blocks.
