Routing
10.3 IP forwarding
● For the PC, the IP router, the IO device and the HMI device, the IP addresses of a
standard gateway or the corresponding routes are also entered.
Figure 10-8
This example configuration results in the following IP routing table for the CPU.
Table 10- 1
Network destination
0.0.0.0/0
192.168.1.0/24
192.168.2.0/24
10.10.0.0/24
For IP communication between the PG/PC and the HMI device, you need to set up additional
IP routes to the IP subnet of the HMI device both in the PC and in the IP router. In the HMI
device, you configure the IP address of the CPU interface X1 as the standard gateway.
