If the control sends a diagnostic request via AS-i.P0, the inverter replies with the currently
pending fault or alarm messages.
Table 7-5 Alarm and fault messages via RP0 … RP3 from the inverter to the AS-i
master (Page 225).

for the CTT2 transfer, four bytes cyclically or acyclically via
PIV. The reading and writing of parameters is possible via the PIV.
Because data is transferred bit
-by-bit, the read and write process is
very slow.
