During configuration, certain information within the relay is assigned to certain physi-
cal interfaces (e.g., binary inputs and output contacts) or logical interfaces (e.g., user-
defined logic, CFC). It must be determined which information should be linked with
which device interface. It may also be determined which properties the information
and the interfaces should have. During allocation, indications and statistical values of
previous events can be lost. Therefore, the operational indication buffer and the sta-
tistic meter should be read out before alterations are made later on.
