4.2.1.17 Read Total Configuration
Meaning
With this command, the following data are read from the CP:
±
The list of active slaves (LAS). This indicates which of the connected slaves are activated.
±
The current configuration data of the connected slaves (I/O configuration and ID code).
±
The current parameters of the slaves (actual parameters).
±
The current flags.
This command can, for example, be used to find out the configuration of the slaves connected to the
AS-i cable after installation. The configuration data read in can be modified if required and saved as
the desired configuration on the CP 142-2 using the 'configure entire system' command (see Section
4.2.1.18.
