This International Standard specifies basic requirements for the installation of media for communication networks in industrial premises and within and between the automation islands, of industrial sites. This standard covers balanced and optical fibre cabling. It also covers the cabling infrastructure for wireless media, but not the wireless media itself. Additional media are covered in the IEC 61784-5 series.<\/p>\n
This standard is a companion standard to the communication networks of the industrial automation islands and especially to the communication networks specified in the IEC 61158 series and the IEC 61784 series. In addition, this standard covers:<\/p>\n
the installation of generic telecommunication cabling for industrial premises as specified in ISO\/IEC 24702;<\/p>\n<\/li>\n
the connection between the generic telecommunications cabling specified in ISO\/IEC 24702 and the specific communication cabling of an automation island, where an automation outlet (AO) replaces the telecommunication outlet (TO) of ISO\/IEC 24702.<\/p>\n<\/li>\n<\/ul>\n
\nNOTE If the interface used at the AO does not conform to that specified for the TO of ISO\/IEC 24702, the cabling no longer conforms to ISO\/IEC 24702 although certain features, including performance, of generic cabling may be retained.<\/p>\n<\/blockquote>\n
This standard provides guidelines that cope with the critical aspects of the industrial automation area (safety, security and environmental aspects such as mechanical, liquid, particulate, climatic, chemicals and electromagnetic interference).<\/p>\n
This standard does not recognise implementations of power distribution through Ethernet balanced cabling systems that are not specified in IEEE 802.3 and in IEEE 802.3at.<\/p>\n
This standard deals with the roles of planner, installer, verifier, and acceptance test personnel, administration and maintenance personnel and specifies the relevant responsibilities and\/or gives guidance.<\/p>\n
