1. An automation system comprising:
a backplane bus;
a first assembly, wherein the first assembly has:
a first control unit configured to control and monitor the first assembly and to undertake the function of a superordinate control unit for the automation system,
a first communication interface connectable to a first segment of a train control and management system network,
a second communication interface connected to the backplane bus,
a first network switch which connects the first communication interface, the second communication interface and the control unit to one another such that data communication takes place according to the Ethernet protocol,
a second assembly, wherein the second assembly has:
a second control unit configured to control and monitor the second assembly,
a third communication interface connected to a second segment of the train control and management system network of the train control and management system network,
a fourth communication interface connected to the backplane bus,
a second network switch which connects the third communication interface, the fourth communication interface and the second control unit to one another such that data communication takes place according to the Ethernet protocol,
wherein the first network switch and the second network switch are configured to establish and process a single tagged VLAN according to IEEE 802.1Q and to form and process a double tagged VLAN according to IEEE 802.1ad,
wherein the train control and management network forms a first single tagged virtual local area network VLAN (V1) according to IEEE 802.1Q, to which the control unit is connected as a terminal device of the train control and management network,
wherein a single tagged VLAN (V3) according to IEEE 802.1Q is established between the first control unit and the second control unit via the backplane bus, via which single tagged VLAN, the control unit communicates with the control unit and controls the latter, and
a first double tagged VLAN (T1) according to IEEE 802.1ad is established between the first network switch and the second network switch via the backplane bus.
