4. Redundant bus connection with component redundancy (option)
The AUMATIC can be equipped with a second (redundant) Profibus inter
-
face. In this version, communication to the actuator can be established
simultaneously through both Profibus interfaces. If one of the Profibus
components fails, e. g. through cable break, those operation commands,
which are sent via the other Profibus component, are executed.
If there is a communication to the master available via both Profibus inter-
faces, the operation commands of the interface which first established a
communication to the master will be executed.
For the bus connection refer to page 5 ff.
Both Profibus DP sub-assemblies have to be programmed in
the same way by the master
(identical setting in the GSD file).
4.1 Settings for the redundant Profibus interface 2 (component redundancy)
The redundant Profibus DP component 2 is set in the same way as the
setting for the Profibus component 1 (see page 10 ff and via the following
menus:
Menu structure
MAIN MENU (M)
SETTINGS (M1)
PROFIBUS DP2 (M1E)
SLAVE ADDRESS (M1EX0)
In case of component redundancy, the parameter CABLE
REDUNDANCY
of both Profibus components must be set to
OFF (this corresponds to the factory setting).
