IAONA Industrial Ethernet -Planning and Installation Guide. Version 4.0, October 2003. Published by IAONA e.V.
Within premises and industrial plants, the importance of the information technology cabling infrastructure is similar to that of other fundamental building utilities such as heating, lighting and mains power supplies. As with other utilities, interruptions to service can have serious impact. Poor quality of service due to lack of planning, use of inappropriate components, incorrect installation, poor administration or inadequate support can threaten an organization’s effectiveness.
For the cabling of office buildings and campuses the international standards ISO/IEC 11801 and EN 50173 have proven to be very successful. They give a structure to the cabling by dividing it into conformance classes and 3 topology layers and by specifying appropriate categories for the
components. If one tries to apply them to cabling projects in industrial plants, there are several issues. This Installation Guide bridges the gaps as long as the appropriate standards for industrial IT cabling are on their way.
