1.2.3 Line Structure

Functional Description

Line structures can be implemented with the SCALANCE X414-3E. The cascading

depth and total span of a network are limited only by the signal propagation times

of the communication connections.

Properties of the Line Structure

Each SCALANCE X414-3E communicates over a TP or FO cable with a neighbor-

ing switch. Communication is possible over the optical ports in slots 5, 6, or 7 or

over the electrical ports in slots 5 and 9 to 11. With the fault mask, it is possible to

monitor the port states using the signaling contact. In addition to interconnecting

the switches, it is also possible to connect one or more end devices to every

SCALANCE X414-3E.

Configuration Example

Sample configuration with SCALANCE X414-3E, SIMATIC S7-300/400 and opera-

tor panel as end devices.
