Requirements
For network separation, the SCALANCE S615 has two VLANs with different
network IDs. As a result, the device has a separate IP address for each VLAN
(in this document: VLAN1: 192.168.2.1 and VLAN2: 192.168.1.1).
Depending on the VLAN it belongs to, this IP address of the SCALANCE S615
must be entered in the terminal (in this document: PC or CPU) as the gateway.
All subnets and IP addresses are only used once in the entire network.
