Protected mode
In protected mode, the IE/AS-i LINK exchanges data only with the configured
AS-i slaves. ”Configured” means that the slave addresses stored on the IE/AS-i
LINK and the configuration data match the values of the existing AS-i slaves.
Actual configuration
The actual configuration in volatile memory of the IE/AS-LINK. These are the
AS-i slaves with which the IE/AS-LINK communicates.
(See also “Expected configuration”)
LAS − List of activated slaves
A bit for every activated AS-i slave is set in this list. The bits of slaves that have
not been activated are reset (zero). The AS-i master stores this list in volatile
memory.
LDS − List of detected slaves
A bit for every detected AS-i slave is set in this list. The bits of slaves that have
not been detected are reset (zero). The AS-i master stores this list in volatile
memory.
LPF − List of periphery faults
This list contains the information whether or not a periphery fault has occurred
for each activated slave (bit is set). If no periphery fault has occurred, the bit is
reset (zero). The AS-i master stores this list in volatile memory.
LPS − List of projected slaves
A bit is set in this list for every configured AS-i slave. The bits of slaves that have
not been configured are reset (zero). The LPS is stored in non-volatile memory
(or on the C-PLUG if inserted).
PCD − Permanent configuration data
The PCD , like the CDI, contains the I/O configuration from project engineering
(input/output configuration) and the identification codes (ID, ID1, ID2) of the AS-i
slaves. The PCD is stored in non-volatile memory (or on the C-PLUG if inserted).
Expected configuration
The expected configuration is stored in non-volatile memory (or on the C-PLUG)
of the IE/AS-LINK. This may possibly differ from the current “actual configura-
tion” (see above).
