Table 4.2.5: Structure of input process data word IN2
The input proces data words are mirroring the output words. Possible
differences at IN1:
 SB indicates a peripheral fault (failure of DALI supply, short circuit on
DALI bus or failure of DALI driver circuitry)
 K is set, when an unsupported command has been received via
INTERBUS local bus (no action on DALI bus)
 AW is set, when a valid response of the DALI ballast has been
received. The answer field is to be interpreted in this case only
(otherwise as in OUT1)
 F is set, when an invalid response of the DALI ballast has been
received (e.g. interference on DALI bus)
