The PG/PC running the SIMATIC Automation Tool and devices connected to the local
network must use the same subnet mask assignment.

Local and remote networks
The following examples show local and remote networks that the SIMATIC Automation Tool
can use. The diagrams are simplified to show basic connectivity and do not show the local
I/O, CPs, and distributed I/O devices (PROFINET and PROFIBUS) that are also accessible.
Different network topologies are also possible.
IP addressing and therefore valid network IP addresses are necessary to get access behind
Ethernet IP routers. You can fill the SIMATIC Automation Tool device table by automatically
scanning a network (Page 26) or by importing a list (Page 56)that identifies stations behind
a router.
