7.2.2.5
Read complete configuration (Get_LAS_CDI_PI_Flags)
Meaning
The following data is read from the AS-i master CM 1243-2 with this call:
● The list of active AS-i slaves (LAS). It specifies which of the connected AS-i slaves are
activated.
● The current configuration data of the connected AS-i slaves (I/O configuration, ID code,
ID1 code, ID2 code);
● The current parameters of the AS-i slaves (actual parameters);
● The current flags.
The call can be used, for example, to determine the configuration of the stations
connected to the AS-i cable after commissioning.
These read-in configuration data can be modified if required and stored in the
AS-i master CM 1243-2 as the planned configuration with the command "Configure
complete configuration" (see section "Configure complete configuration
(Set_LPS_PCD_PP_Flags) (Page 70)").

7.2 Description of the AS-i line calls and AS-i slave calls
Meaning
The flag is set when the planned configuration (configured) and the actual
configuration match.
The flag is set if an AS-i slave with operating address 0 is available.
The flag is set if automatic address programming is possible
(i.e. SET_AUTO_ADDR_ENABLE = 1 and no "incorrect" AS-i slave is connected to
AS-Interface).
The flag is set if automatic address programming can be performed (i.e. exactly one
AS-i slave has currently failed).
The flag is set in configuration mode and reset in protected mode.
The flag is set when the AS-i master CM 1243-2 is in normal operation.
(The flag is set when the link is in normal operation)
The flag is set if the voltage on the AS-i cable is too low.
The flag is set if the offline phase is active.
The flag is set if at least one AS-i slave signals a peripheral fault.
The flag "DATA_EXCHANGE_ACTIVE" is set when cyclic data traffic is in normal
operation.
The flag is set if the operating status OFFLINE is to be adopted or has already been
adopted.
The flag indicates whether automatic address programming by the user is disabled
(BIT = 0) or enabled (BIT = 1).
The flag is set if the EPROM of the device is OK.
