After the fieldbus stations are switched on, they all assume
the "waitParam" status and wait for instructions from the
higher-level DP master.
In this status, the bus node waits for parameters of the DP
master.
In this status, the bus node waits for the set configuration of
the DP master.
In this status, the bus node is exchanging data (DataEx-
change) with the DP master. User data and diagnostic inform-
ation can be transmitted thereby.
