AS-i Slave Lists
The AS-i Slave lists LPS, LDS, LAS, LCS, LOS and the configuration error list are built
up as follows:
byte
bit
0
slave
-
byte
bit
0
slave
16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
Meaning of the Lists:
LPS List of Projected Slaves
LDS List of Detected Slaves
LAS List of Activated Slaves
LCS List of Corrupted Slaves
List of those slaves, that have caused a short-time configuration error.
LOS List of Off-line Slaves
List of those slaves, with that in case of configuration error the AS-i Master
shall switch to the Off-line phase.
configuration error list
A bit in the configuration error list is set, if the concerning bit in the LPS (List
of Projected Slaves) differs from the one in the LDS (List of Detected Slaves)
or if the projected AS-i configuration data (I/O- and ID-code) of the concern-
ing AS-i slave differ from the detected configuration in the AS-i circuit.
11.2
Execution Control Flags
The execution control flags are transmitted in the diagnosis telegram, if the gateway
is operated in the professional mode.
When set, the individual bits have the following meaning:
bit 0:
config_OK
bit 1:
LDS.0
bit 2:
Auto_Address_Assign
bit 3:
Auto_Address_Available
bit 4:
Configuration_Active
bit 5:
Normal_Operation_Active normal operation active
bit 6:
