Configuration mode
In configuration mode, all AS-i slaves that are found are activated. Automatic addressing is possible, with the
next free address being assigned when a slave with address 0 is found. However, an AS-i address can be
manually set via the index
0x2000 [
}
134]
(AS-i command interface). All the AS-i slaves found can be
projected by setting the set input. In this case, the
• corresponding I/O IDs and ID codes are also entered into the indices
0x8pp0:20 [
}
130]
,
0x8pp0:25
[
}
130]
(projected I/O IDs) or
0x8pp0:21 [

and

, as well as
0x8pp0:23 [

(projected ID codes) and

Operating phases
Offline
After power-on, the AS-i master goes into offline mode, i.e. there is no communication with the AS-i slaves.
During normal operation, the AS-i master can be put into offline mode (OFFLINE-flag is set) via the process
data. The output data of all activated AS-i slaves are set to default value 1
bin
, and the input data of all
activated AS-i slaves are set to default value 0
bin
. The AS-i master is then in offline mode and will send no
further AS-i commands.
Start-up
Detection phase
During the detection phase, the I/O ID and ID codes of all AS-i slaves are queried and entered in parameters
-
0x9pp0:20 [
}
138]
,
0x9pp0:25 [
}
138]
(I/O IDs read) or
-
0x9pp0:21 [
}
138]
,
0x9pp0:26 [
}
138]
(ID codes read),
-
0x9pp0:22 [
}
138]
,
0x9pp0:27 [
}
138]
(Extended ID codes 1 read) and
-
0x9pp0:23 [
}
138]
,
0x9pp0:28 [
}
138]
(Extended ID codes 2 read).
All AS-i slaves found are entered in the
L
ist of
D
etected AS-i
S
laves (LDS), index
0xF101 [
}
141]
. The AS-i
master will only enter the activation phase once at least one slave was detected or found.
Activation phase
In protected mode the AS-i master activates only the projected AS-i Slaves from the
L
ist of
P
rojected
S
laves
(LPS, index
0xF103 [
}
142]
).
In configuration mode, all AS-i slaves that were found during the detection phase are activated. To this end
the AS-i master sends a parameterization call (activation parameter,
0x8pp0:24 [
}
130]
,
0x8pp0:29 [
}
130]
)
and a data call (with the default values 1
bin
as outputs). All activated slaves are entered in the
L
ist of
A
ctivated
S
laves (LAS, index
F102 [
}
141]
). Once all AS-i slaves have been processed, the AS-i master
automatically enters the data exchange phase.
Normal operation
Data exchange phase
During the data exchange phase, the AS-i master exchanges data with each activated AS-i slave. If an AS-i
slave does not respond in three consecutive data exchange phases, it is removed from the LAS and the
LDS, and its inputs are set to the default value 0
bin
. Once a data cycle has been completed with all activated
AS-i slaves, the AS-i master enters the management phase.
