Configuration Error/Config Error
An configuration error is indicated, when target and actual configuration of the con-
nected slaves do not match. The following cases may result in configuration errors:
Missing slave:A slave entered in the
⇒
LPS
is not available
Erroneous type of slave:The
⇒
slave profile
of the connected slave does not com-
ply with the configured one.
Unknown slave:A connected slave is not entered in the
⇒
LPS
.
LAS - List of Activated Slaves
The master exchanges IO data with the slaves entered in the LAS. In the proteced
mode only those detected slaves (
⇒
LDS
) are activated which are expected by the
master and are entered in the
⇒
LPS
. In the configuration mode all slaves entered
in the
⇒
LDS
are activated.
LDS - List of Detected Slaves
All slaves from which the master was able to read the
⇒
slave profile
are entered
in the LDS.
LPF - List of Peripheral Faults
There is a list of peripheral faults only for masters fulfilling the new specification
2.1. This list includes an entry for each slave that signals a
⇒
peripheral fault
.
LPS - List of Projected Slaves
The list of projected slaves includes all slaves expected by the master. All entries
of the
⇒
LDS
are taken over to the LPS by storing the actual configuration (except
for a not addressed slave with the address 0).
Offline phase
In the offline phase all input and output data is reset. This phase is entered at start-
up of the master, after a
⇒
AS-i power fail
, and at the transition of the
⇒
configu-
ration mode
to the
⇒
protected mode
.
Furthermore the master can actively be put into the offline phase with the offline
flag.
During the offline phase, masters with a display show code "40".
