supplied to the Profibus master. The format of the diagnostics byte is shown here:

Reserved bits indicated in the above table are currently set to “0” by the PBDP-110,

When a drive’s fault condition is cleared, a diagnostics status update is generated

indicating the drive’s exit from the faulted state.
