3.9 Using Power over Ethernet
Task
In a plant in the food and beverages industry, two new production areas and an additional
outside storage area need to be integrated into an existing IT infrastructure. Due to the large
distances between the new parts of the company minimization of the cabling effort was
sought.
Solution
This aim is to be met by the practically end-to-end use of components capable of PoE. In
addition to this, access points allow access to the company network from any location. The
starting point for connecting the new production areas and the storage area to the company
network are two devices of the SCALANCE X series that provide an adequate number of
Ethernet ports with PoE capability. The code readers
connected to the company network via a SCALANCE XM408-8C
XM408-8C can be expanded by port extenders. When necessary, 16 ports are available if
additional readers become necessary. With a suitable port module, connection to the
existing fiber-optic cables can be achieved without problems.
