What happens if the PROFIBUS cable has a short-circuit?
A short-circuit in the PROFIBUS cable will in most cases disturb the data communication in the particular segment. The devices in that area will NOT get damaged! The short-circuit can easily be detected with an oscilloscope and even the distance to the problem point. If the end-user wants to keep the installation running during a short-circuit he can pick the following solutions: Install a redundant system. Divide the installation in more parallel segments coupled by repeaters, OLMs or ProfiHubs. Install the cable in secured cable trays.
