8.2.2.7 Get list of peripheral faults (GET_LPF)
With this call, the list of peripheral faults (LPF) signaled by the AS-i slaves is read
out from the AS-i master. The LPF is updated cyclically by the AS-i master. If and
when an AS-i slave signals faults of the attached peripherals (for example broken
wire) can be found in the description of the AS-i slave.
8.2.2.8 Get List of Offline Slaves (GET_LOS)
With this call, the list of slaves causing the offline phase when a configuration error
occurs in being read out (List of Offline Slaves, LOS).
The user can choose the reaction of the master when a configuration error occurs.
The master can be switched off line when an important slave causes a configura
-
tion error; less important slaves can send an error to the host, AS-i however will
not be switched offline.
8.2.2.9 Set List of Off-line Slaves (SET_LOS and SET_LOS_R6 (6Dh))
The call SET_LOS_R6 (6D
16
) differs to the call GET_LOS in the half long LOS list.
With the bit 2
5
is selected if the upper (=1) or lower (=0) part of the LOS is written.
With this call, the list of slaves causing the offline phase when a configuration error
occurs in being defined (List of Offline Slaves, LOS).
The user can choose the reaction of the master when a configuration error occurs.
The master can be switched offline when an important slave causes a configura
-
tion error; less important slaves can send an error to the host, AS-i however will
not be switched offline.
8.2.2.10 Get transm.err.counters (GET_TECA)
With this call the error counters of all single slaves/A-slaves can be read (see
chapter 7).
With every reading out of the counts, the error counters will be restarted.
The counts are being read out via the corresponding host interface and will be de-
leted with every read access. The counter´s value is limited to 254. 255 will cause
a counter overflow.
