Most PROFIBUS faults are physical: missing or double termination, cable segments that are too long for the baud rate, spur lines, damaged connectors, poor shielding or grounding, and interference from nearby drives. Configuration errors such as duplicate station addresses or a wrong baud rate are the next most frequent cause.
Connect a PROFIBUS analyzer such as ProfiTrace to the bus. Within minutes it shows a live list of every station, measures the signal quality of each device with a built-in oscilloscope and bar graph, records messages and counts errors such as retries and lost stations. This tells you which device or segment is causing the problem.
