1.3.2 Diagnostic parameter register
The diagnostic parameter registers are always written to when a fault occurs and whenever
one of the error bits is set (F_PW_BIT, F_PF_BIT, F_BUS_BIT, F_CTRL_BIT). Otherwise,
the diagnostic parameter register has the value 0000
hex
.
The diagnostic parameter registers provide additional information on the status indicated in
the diagnostic status register when the error bits specified above are set.
The diagnostic parameter register 1 contains the error code. 
An overview of the error codes can be found in Section 2, “Error codes”.
The diagnostic parameter register 2 contains additional information. For localized bus or I/O
errors, this is the error location or the device number. The error location is stored as a slot
number. This starts at 1 and corresponds to the sequential number of the Axioline F mod-
ules that are installed one after another.
