Required
Property
This client is activated by default, i.e. this S-DIAS hardware module at this
position is absolutely necessary for the system and may under no
circumstances be missing, disconnected or deliver an error, otherwise, the
entire hardware is switched off. If the hardware module is missing, it returns
an error or if it is removed, this triggers an S-DIAS error. 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, the components to be identified as "not required" should be selected
with regard to the safety of the system.
