Functional Bonding and Shielding
Guideline for PROFIBUS and PROFINET
The organization PROFIBUS & PROFINET International has published recommendations for Functional Bonding and Shielding of PROFIBUS and PROFINET in a document of the same name. Thanks to the diverse, practical input from numerous fieldbus users, the document brings the current state of the art in line with the valid norms. By applying the measures formulated there, material and assembly costs can be significantly reduced when setting up optimum equipotential bonding, while at the same time increasing the immunity of the machines and systems to electromagnetic influences.
