PROFINET IO Diagnosis Guideline

PROFINET IO is now available in Version 2.3. Besides the specification of the protocol behaviour, this specification also describes diagnosis aspects. This is a unique feature of the technology. Protocol internal diagnosis mechanisms are already defined. The utilisation of diagnosis functions in context of a plant is mostly left to the user. For this reason, a guideline especially for the topic diagnosis in PROFINET IO environments has been developed. This document shall ensure the unification of the usage of such mecha­nisms and potential users shall be assisted with their solutions. The editor of the guideline comes from ifak and the development is based on a co-operation between the PROFINET IO working group of PROFIBUS International and their members. An important aspect of the guideline is the description of the hierarchical diagnosis of PROFINET which was requested by the AIDA. This will be achieved with respect to the speci­fication of the controller-controlller communication for PROFINET. The current version of this guideline is in the review phase by the PI and the AIDA. After the integration of collected review comments and change requests, this document will be published by the PI.
