Download Basic description of the system

manual changes are recorded directly into the database where the time of the manual change is
assigned and any recalculation is made if the value is part of the recalculation.
Automatic changes of values are first recorded into the database. The time of registration is saved
into the database by the respective system. If the value is part of the recalculation, the recalculation is
performed. Moreover, there is the evaluation of the exceeding of limits which are recorded into the diary.
The system distinguishes two limits. The first limit I is the users and is set by the dispatcher The second
limit II is set by the system administrator and is user non-accessible. Both limits are identical in terms of
processing and independence. These can be set to a different value. Both limits are saved into the diary, even
in the case that they are set at the same value.
