The Configuration FC is responsible for initialising the system configuration
such as gathering and storing configuration from FC‘s and Devices. It is also
responsible for tracking configuration changes and planning for future extension
of the system.

As such, the main functions of the Configuration FC are to retrieve a
configuration and to set the configuration:

 The retrieve configuration function allows to retrieve the configuration

of a system, either from history (latest known configuration) or from the

system (current configuration, including retrieval of the configuration of

one or a group of Devices), enabling tracking of configuration changes.

The function can also generate a configuration log including descriptions

of Devices and FCs. A filter can be applied to the query;

 The set configuration function is mainly used to initialise or change the

system configuration.

The goal of the Fault FC is to identify, isolate, correct and log faults that occur
in the IoT system. When a fault occurs, the respective functional component
notifies the Fault FC. Such notification triggers, for instance, are the gathering of
more data in order to identify the nature and severity of the problem. Another
action can encompass bringing backup equipment on-line.

Fault logs are one input used for compiling error statistics. Such statistics can
be used for identifying fragile functional components and/or devices. Also,
