No. BA: Write_overall_configuration

Meaning
This command transfers the desired overall configuration of AS-Interface to the AS-i master
and saves it as the CONFIGURED configuration in the non-volatile EEPROM. This
configures the AS-i master.
When this command is executed, the AS-i master changes to the offline phase and then
switches back over to "normal operation". The AS-i master restarts.
The "Protected operation" or "Configuration mode" operating mode of the AS-i master after
execution of the command is determined by the "Configuration_Active" flag (see Table
"Structure of Flag 1 and Flag 2").
This command is permissible both in "Protected operation" and "Configuration mode.
Note
Configuration data are overwritten
If you configure the AS-i slaves using
command described here. If you have configured proxy slaves, you can specify the
configuration data of the proxy slaves with this command. To avoid the offline changeover,
the configuration data of the proxy slaves can be specified preferentially with the "No. D0:
Set_Configuration_Online (Page 159)" command.
If you use this command, you will overwrite the corresponding configuration data that
resulted from configuring the AS-i master using the "SET" button or configuring using
STEP 7
Specifically, the following data are transferred:
● List of configured AS-i slaves
This specifies which AS-i slaves are permitted to be activated by the AS-i master in
"protected operation".
● List of configuration data.
This specifies the ID codes and the IO code that the connected AS-i slaves must have.
● The list of the AS-i slave parameters that have been configured in the AS-i master and
stored in non-volatile memory. These parameters are transferred to the AS-i slaves when
the AS-i master starts up.
● The flags that determine the operating state of the AS-i master after startup.
