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.
on the CP 243-2.
A set bit can indicate the following:
Missing slaves
Extra slaves (not in the configuration)
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.
