Pok Periphery_Ok
This flag is set when no AS-i slave is signaling a peripheral fault.
S0 LDS.0
This flag is set when an AS-i slave exists with address 0.
AAs Auto_Address_Assign
This flag is set when the automatic address programming is possible (in oth-
er words, AUTO_ADDR_ENABLE = 1 and there is no “incorrect” slave con-
nected to the AS-i Interface).
AAv Auto_Address_Available
This flag is set when the automatic address programming can be executed
(in other words, exactly one AS-i slave is currently out of operation).
CA Configuration_Active
The flag is set in the configuration mode and reset in the protected mode.
NA Normal_Operation_Active
This flag is set when the AS-i master is in normal operation.
APF APF
This flag is set when the voltage on the AS-i cable is too low.
OR Offline_Ready
The flag is set when the offline phase is active.
Cok Config_Ok
This flag is set when the desired (configured) and actual configuration match.
AAe Auto_Address_Enable
This flag indicates whether the automatic address programming is enabled
(bit = 1) or disabled (bit = 0) by the user.
OL Off-line
This flag is set when the mode is to changed to OFFLINE or this mode has
already been adopted.
DX Data_Exchange_Active
If the "Data_Exchnge_Active" flag is set, the the data exchage between AS-i
master and slaves is available in the dataexchange phase. If this bit is not
set the data exchange is not available. The read ID telgegrams are transmit-
ted to the slave.
The bit is set if the AS-i master entries the offline phase.
8.3.2.18 SET_OP_MODE
This call changes the module between the configuration mode and the protected
mode.
In the protected mode, only AS-i slaves are activated that are entered in the LPS
and whose expected and actual configurations match, in other words, when the I/
O configuration and ID codes of the detected AS-i slaves are identical to the con-
figured values.
