This client is active by default, which means that the S-DIAS hardware module
at this position is mandatory for the system and can under no circumstances
be disconnected or return an error. Otherwise, the entire hardware
deactivated. If the hardware module is missing or removed, an S-DIAS error
is triggered. If his client is initialized with 0, the hardware module located in
this position is not mandatory. This means that it doesn't have to be available
or error-free. However, which components identified as "not required" should
be selected with regard to the safety of the system.
