Basic properties of the SCALANCE X devices
Type of mounting
Apart from a few exceptions, the devices are suitable for wall mounting, DIN rail mounting
and S7-300 or S7-1500 standard rail mounting. In individual cases the required type of
mounting can be realized by using a mounted adapter.
Devices with the supplement R are either suitable as a desktop device or for installation in a
19" rack.
Management functions
The devices SCALANCE X-000, SCALANCE XB-000, SCALANCE X-100, SCALANCE XB-
100 and SCALANCE XC-100 have no management functions. These "unmanaged switches"
are therefore cheaper.
The devices SCALANCE X-200, SCALANCE X-300, SCALANCE X-400 and SCALANCE X-
500 are equipped with management functions. These devices are also known as "managed
switches". The managed switches provide numerous configuration and diagnostics functions
for more convenient operation of an Industrial Ethernet network.
Electrical and optical interfaces
The SCALANCE X devices can be used as switches in both optical and electrical Industrial
Ethernet networks. Each performance class therefore includes devices with varying numbers
of electrical and optical interfaces. The optical interfaces also include versions specially
designed to cover long distances. These are available in devices that have LD, LH, LH+ or
ELH in the device designation.
