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.
