Analog Module
The analog module occupies 16 input and 16 output bytes in the address area of
the analog inputs and outputs. Data exchange with the AS-i slaves is handled via
the analog module (see Figure 2-1).
The bank select mechanism means that a larger data area in total can be
addressed in the analog module than the addressable data area in the S7-200
CPU for the expansion module.
