Notice!
Input I/O 1 (pin 2) - laser ON/OFF:
If the laser diode of the AMS 384
i
is deactivated, the data double word A0 00 00 00
H
is trans-
ferred. In this case, bit 31 is permanently set to logic
1
and message "
PLB
" is transferred,
see chapter 9.5 "Interbus data format - 32-bit input data".
9.4

i
The AMS 384
i
is classified with Interbus
Ident code 32
H
. The classification describes the
AMS 384
i
as a remote bus participant with 32-bit input data.
