Connecting Multiple Device Combinations to the Control Center via External
Ethernet Switches
You can create several of the SICAM MMU and SICAM I/O Unit 7XV5673 device combinations as shown in
chapter 6.4.3 and apply them in a more complex device configuration by using external Ethernet switches. The
following figure illustrates the cabling of the devices and the possible transmission protocols.
