This could be a cabling/connector problem, a missing termination on the bus (a Profibus problem) or a faulty module on a remote I/O node. The faulty node will also activate it's own BF LED to help identify it. BF means "bus fault", and indicates a problem communicating to a node in Profibus or Profinet. This could be a cabling/connector problem, a missing termination on the bus (a Profibus. S7-300 CPUs use 2 diagnostic LEDs to show the user that something is wrong: S7-300 CPUs use 2 diagnostic LEDs to show the user that something is wrong: - BF means 'bus fault', and indicates a problem communicating to a node in Profibus or Profinet.
