Controller fail: if the controller goes in fail mode, an external
diagnostic service is required and one byte in the diagnostic
buffer signals the type of failure.
User parameter mismatch: if the user sets one or more
parameters out of their allowed range, a ProfiBus external
diagnostic service is required and some bits in the diagnosis
frame signals which parameter is wrong (i.e. over range or under
range).
