Creating A Device Combination Via An External Ethernet Switch And Connection To The Control Center - Siemens SICAM MMU 7KG9663 Device Manual

6.4.3 Creating a Device Combination via an External Ethernet Switch and
Connection to the Control Center
You can use an external Ethernet switch to connect the SICAM MMU with the SICAM I/O Unit 7XV5673. In this
case, the internal Ethernet switch of the SICAM I/O Unit 7XV5673 is not used. Furthermore, you can connect
this device combination to the control center using the external Ethernet switch. The following figure illustrates
