Connecting Multiple Device Combinations to the Control Center

You can create several SICAM MMU and SICAM I/O Unit 7XV5673 device combinations as shown in
chapter 6.4.1 and apply them in a complex device configuration by using an external Ethernet switch. The fol-
lowing figure illustrates the cabling of the devices and the possible transmission protocols.
