Abstract
Coupling of bus systems is simplified. To this end, a coupling device is disclosed that is used to couple two field buses to a periphery bus. The periphery bus can be used to connect input/output modules for the central monitoring or processing of data. For example, the coupling device can be configured in terms of the transfer of standard data and security-relevant data between the three bus systems.
Claims14
A coupling apparatus for data buses, comprising:
- a first connecting device for a first data bus;
- a second connecting device for a second data bus, as additional to the first connecting device;
- a data processing device, connected to the first and the second connecting device to allow data to be interchanged between the data buses;
- and
- a third connecting device, connected to the data processing device, for a third data bus, as additional to the first and second data buses, to allow data to be interchanged between the three data buses.
