Siemens CP 243-2 Bank 1 Diagnostics on the AS-Interface, Banks 16±30 Reserved area

Interface to the User Program in the S7-200 CPU

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:

SMissing slaves

SExtra slaves (not in the configuration)

SSlaves 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. (m: start address of the analog input area of the CP 243-2)

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.
