If you have several remote cabinets with profibus stations at a distance of about 100 m, do you take special precautions towards grounding to minimize problems with profibus communication?
The remote cabinets will take their power from the main cabinet, so a ground connectin cable will also arrive from the main cabinet in the remote cabinet. But normally the section of this ground connection is not big. Is there a minimum crosssection of the ground PE-cable that you should advise to avoid communication problems due to ground differences?
Thanks
