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 interna-tional 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 organiza-tions 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 misinter-pretation 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 Publica-tions. 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 61784-5-6 has been prepared by subcommittee 65C: Industrial networks, of IEC technical committee 65: Industrial-process measurement, control and automation.

INTRODUCTION This International Standard is one of a series produced to facilitate the use of communication networks in industrial control systems. IEC 61918:2007 (Ed. 1.0) provides the common requirements for the installation of communi-cation networks in industrial control systems. This installation profile standard provides the installation profiles of the communication profiles (CP) of a specific communication profile family (CPF) by stating which requirements of IEC 61918 fully apply and, where necessary, by supplementing, modifying, or replacing the other requirements (see Figure 1). For general background on fieldbuses, their profiles, and relationship between the installation profiles specified in this standard, see IEC/TR 61158-1. Each CP installation profile is specified in a separate annex of this standard. Each annex is structured exactly as the reference standard IEC 61918 for the benefit of the persons representing the roles in the fieldbus installation process as defined in IEC 61918 (planner, installer, verification personnel, validation personnel, maintenance personnel, administration personnel). By reading the installation profile in conjunction with IEC 61918, these persons immediately know which requirements are common for the installation of all CPs and which are modified or replaced. The conventions used to draft this standard are defined in Clause 5. The provision of the installation profiles in one standard for each CPF (e.g. IEC 61784-5-6 for CPF 6), allows readers to work with standards of a convenient size.

Where there is no corresponding subclause of IEC 61918:2007 in the normative annexes in this standard, the subclause of IEC 61918:2007 applies without modification. The annex heading letter represents the installation profile assigned in Clause 4 The annex heading number shall represent the corresponding numbering of IEC 61918:2007. EXAMPLE
“Annex A.4.4” in IEC 61784-5-6 means that the installation profile for the Type 8 network profiles specifies the Subclause 4.4 of IEC 61918:2007. All main clauses of IEC 61918:2007 are cited and apply in full unless otherwise stated in each normative installation profile annex. If all subclauses of a (sub)clause are omitted, then the corresponding IEC 61918 (sub)clause applies. If in a (sub)clause it is written “Not applicable”, then the corresponding IEC 61918 (sub)clause does not apply. If in a (sub)clause it is written “Addition”, then the corresponding IEC 61918 (sub)clause applies with the additions written in the profile. If in a (sub)clause it is written “Replacement”, then the text provided in the profile replaces the text of the corresponding IEC 61918 (sub)clause. NOTE
A replacement can also comprise additions. If in a (sub)clause it is written “Modification”, then the corresponding IEC 61918 (sub)clause applies with the modifications written in the profile. If all (sub)clauses of a (sub)clause are omitted but in this (sub)clause it is written “(sub)clause x has “Addition” (or “Replacement”) or is “Not applicable””, then (sub)clause x becomes valid as declared and all the other corresponding IEC 61918 (sub)clauses apply.
