IEC 61784-5-3:2013 specifies the installation profiles for CPF 3 (PROFIBUS/PROFINET). Each CP installation profile is specified in a separate annex of this standard. The IEC 61784 series is produced to facilitate the use of communication networks in industrial control systems. This third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. It includes the following changes:
- an addition of 4-pair cabling,
- an addition of the connector M12 X-Coding,
- an addition of the definition of end-to-end links,
- a revision of Table C.17 and
- a formula for the NEXT limits of end-to-end links.

This publication is to be read in conjunction with IEC 61918:2013.
