Siemens SIMATIC PCS 7 Function Manual

Note
Address areas and IP addresses of the components on the plant bus
Always assign IP addresses in different IP address ranges to the network adapters (separate
address range for Bus1 and separate address range for Bus2).
Example:
● Ring 1:
– IP address area: 192.168.1.0 - 192.168.1.255
– Subnet mask: 255.255.255.0
● Ring 2:
– IP address area: 192.168.2.0 - 192.168.2.255
– Subnet mask: 255.255.255.0

In this system, one CP 16x3 or one subsystem of the AS can fail in the OS server without
affecting the overall system. The plant bus (bus) is configured redundantly and with redundant
switches in each case. As a result, a failure of the bus component and all components involved
(switches) is covered.
