Actual parameter
The AS-i parameter that have been sent last to the AS-i slave, in contrary to
⇒
permanent parameters.
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".
