A.2 Content of the standards
Content of the standards IEC 24702 and EN50173-3
The standards for the application-neutral building networking of industrially used buildings
describe:
● Structure of the building network
● Performance requirements for cables (fiber-optic cable, electrical),
● Performance requirement for plug-in connector (fiber-optic cable, electrical),
● Limit values for permanent links.
The IEC 24702 references the IEC 11801.
Installation-specific aspects are described in the IEC 14763 (EN50174).
Content of the standards IEC 61918 and IEC61784
The standards for the automation networks contain a general part which describes the
following points:
● Network design (network structure, grounding, bonding),
● Planning and installation,
● Component requirements (plug-in connectors, cables, grounding, etc.)
● Installation inspection,
● Maintenance and repair
The
IEC 61918
contains general requirements that are common for all fieldbuses
(PROFINET, PB, Interbus, etc.).
Fieldbus-specific aspects/requirements that deviate from the general part are also described
in the profile-specific standards, for example, in
IEC61784-5-3
for PROFIBUS, PROFIBUS
PA and PROFINET; IEC61784-5-6 for Interbus.
