Analogue I/Os
The analogue I/Os each occupy the word range of the first
station which is not assigned by the system diagnosis or by
digital I/Os.
Slave > Master Master > Slave
Device no. Signal name Device no. Signal name
RWr(n+m)0 Analogue input 0+m (0, 4, 8, 12) RWw(n+m)0 Analogue output 0+m (0, 4, 8, 12)
RWr(n+m)1 Analogue input 1+m (1, 5, 9, 13) RWw(n+m)1 Analogue output 1+m (1, 5, 9, 13)

Tab.2/11: System diagnosis: I/O diagnostic interface and status bits
The bit range of the stations used by the analogue I/Os is
reserved.
Analogue outputs can be activated or deactivated with the
word Control" in the bit range of the relevant station. See
following table. The following bits are used here:
