Technical Information
Controller Fails
If the controller switches to 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).
