Bit 1
Bit 2
So, if the first byte is equal to 0, the interface is working properly,
otherwise there is a problem.
Following the first user diagnostic byte there are the diagnostic
buffers correlated to each device connected to the low-speed network
(RS-485).
Each buffer is divided in two sections:

Parametrisation Diagnostic

Two bytes reporting the result of each single parameterisation
operation (MSB of byte 0 is correlated to the first parameters, LSB of
byte 1 is correlated to the 16th parameter).
Refer to the relative "Parameter Buffer Structure" "Diagnosis byte-bit"
column.

Output Buffer Diagnostics

Each nibble in the bytes following the parametrisation diagnostic
buffer, represents the status of the last attempt to write a parameter
with following coding (diag status byte):
0
