_____________
INTRODUCTION
Attention is drawn to the fact that the document IEC 61918 specifies all the installation
requirements that apply to large part of the industrial communication networks and that these
requirements automatically apply to each single network with the exception of those
requirements that in the relevant document of the IEC 61784-5 series are explicitly defined as
modified or replaced.
All the additions to the latest edition of the IEC 61918 apply to the networks of CPF 12.
Nevertheless, the fact that a few tables of IEC 61918 have been restructured to better define
the technical content requires that the document IEC 61784-5-12 Ed.1 be amended to fully
match the IEC 61918 revised structure.
