Bank 1: Diagnostics on the AS-Interface
The delta list of the AS-i slaves is indicated in this bank.
The delta list contains deviations of the existing AS-i slaves from the configuration
on the CP 243-2.
A set bit can indicate the following:
S
Missing slaves
S
Extra slaves (not in the configuration)
S
Slaves with incorrect I0/ID coding
The delta list is updated both in the configuration and in the protected mode.
The bytes and bits of the delta list are ordered as shown in the table below.

Banks 2–15: Response data on the AS-Interface
These banks contain the response data of the command calls. The data structures
used and the codings are described in Section 5.2. The number of banks used
depends on the particular command.
Banks 16–30: Reserved area
These areas are reserved for later expansions and cannot be used.
Bank 31: Binary input data of the AS-i slaves 1B – 31B
Via these analog input words, you have access to the binary inputs of the B slaves
(slaves with the extended addressing mode).
The structure of the input data is described in Section 3.1.
