Functional Earthing and Shielding

PROFINET , PROFIBUS

Description:

Functional Earthing and Shielding  of PROFIBUS and PROFINET
This document deals with functional earthing, the shielding of PROFIBUS/PROFINET networks and with equipotential bonding in the corresponding plants in non-hazardous areas. The document describes an optimized structure for process automation systems intended to reduce the effects of electromagnetic interference (EMI) and disturbances by using equipotential bonding systems. In a tiered approach, the readers are first made familiar with the technical basics of electromagnetic compatibility (EMC), equipotential bonding and shielding. In chapter 4, six recommendations for action are developed by using a plant example.
 

This document has no normative character. It may be useful in certain operating environments, in certain technical constellations or when used in certain countries to deviate from the given recommendations. In this case, installers and operators of the plant should weigh up the advantages and disadvantages of the recommendations made in the specific application and, if deemed appropriate, decide on the implementation of a different solution if necessary.

Funktionserdung und Schirmung von PROFIBUS und PROFINET
Dieses Dokument befasst sich mit der Funktionserdung und Schirmung von PROFIBUS-/PROFINET-Netzwerken sowie dem Potentialausgleich in den zugehörigen Anlagen außerhalb von Ex-Bereichen. Dieses Dokument befasst sich mit einem optimierten Aufbau von automatisierungstechnischen Anlagen, um die Auswirkungen elektromagnetischer Störungen, sowie Störungen über Potentialausgleichssysteme zu reduzieren. In einem mehrstufigen Ansatz werden die Leser zunächst mit Grundlagen zu den Themen elektromagnetische Verträglichkeit, Potentialausgleich und Schirmung vertraut gemacht. Anschließend werden in Kapitel 4 sechs Handlungsempfehlungen anhand einer Beispielanlage hergeleitet.
 

Dieses Dokument hat keinen normativen Charakter. Es kann in bestimmten Einsatzumgebungen, in bestimmten technischen Konstellationen oder beim Einsatz in bestimmten Ländern sinnvoll sein, von den gegebenen Handlungsempfehlungen abzuweichen. Errichter und Betreiber der Anlage sollten in diesem Fall die Vor- und Nachteile der gemachten Empfehlungen in der konkreten Anwendung abwägen und, sofern als sinnvoll erachtet, gegebenenfalls die Umsetzung einer abweichenden Lösung beschließen.
