3.1 Linear structure
Functional description
Linear structures can be created with the IE Switches X-300. The cascading depth and total
span of a network are limited only by the signal propagation times of the communication
connections.
Properties of the linear structure
Each IE Switch X-300 communicates over a TP or FO cable with a neighboring Ethernet
switch. Communication is possible over the optical or the electrical ports.
Configuration example
Sample configuration with SCALANCE X308-2, SIMATIC S7-300/400 and operator panel as
end devices.

3.2 Star/tree structure
Functional description
Star/tree structures can be created with the IE Switches X-300. The cascading depth and
total span of a network are limited only by the signal propagation times of the communication
connections.
