An important advantage of PROFIBUS as a protocol is the built-in diagnostic capabilities.  PROFIBUS allows for alarming to be updated with data blocks. 

Siemens also offers a wide array of hardware and software devices to make troubleshooting simple.  This ability to diagnose anything from a cable break to a non-responding device helps keep your plant profitable and also helps speed commissioning time.
