Reference or pointer variables (as well as other variables) provided with this attribute will be set
to their initial value after an online change.
Thus the occurrence of an online change can be identified.
Thus the initialisation processes can be executed again
(after an online change has been
completed).
Use interface references
During an online change, interface references (interfaces) are automatically checked and adapted.
When interfaces and interface references are used for the ApplicationTemplate, please note that
the use is not required in a purely functional way and that it is only required for the purpose of the
online change.
In order to be able to access an FB instance, an additional method call of the interface (pointer/
reference to the FB instance) is required.
