Interface to the User Program in the S7-200 CPU

2-3

SIMATIC NET CP 243-2 AS-i Master

C79000-G8976-C142/02

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.
