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.

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:
