Design
The SCALANCE Industrial Ethernet switches with a rugged
metal housing are optimized for mounting on a standard rail and
an S7-300 rail. Direct wall mounting in various positions is also
possible. Due to the dimensions of the housing that conform to
those of SIMATIC S7-300, the devices are optimized for integra-
tion in an automation solution with S7-300 components.
The SCALANCE X-100 switches have:
•
A 4-pole terminal block for connecting the redundant supply
voltage (2 x 24 V DC)
•
A row of LEDs for displaying status information
(power, link status, data communication, signaling contact)
•
A 2-pole terminal block for connecting the floating signaling
contact
•
A SET button for on-site configuration of the signaling contact
The following port types are available:
•
10/100BaseTX, RJ45 port;
automatic detection of the transmission rate
(10 or 100 Mbit/s), with autosensing and autocrossover
functions for connecting IE FC cables using
IE FC RJ45 Plug 180 up to 100 m
•
10/100BaseTX, RJ45 ports and
Power-over-Ethernet functionality;
automatic detection of the transmission rate
(10 or 100 Mbit/s), with autosensing and autocrossover
functions for connecting IE FC cables using
IE FC RJ45 Plug 180 up to 100 m and integrated Power-over-
Ethernet functionality according to IEEE 802.3at Type 1
•
100BaseFX, BFOC port;
for direct connection to the Industrial Ethernet glass FOC
up to 5 km
■
Function
•
Construction of electrical and optical Industrial Ethernet line or
star topologies
•
Use of uncrossed connecting leads is possible due to
integrated auto-crossover function of the ports
•
Power supply of Power-over-Ethernet-capable terminal
equipment via the data line for SCALANCE X108PoE
•
Isolation of the load due to integrated switch functions
•
Easy network configuration and network expansion;
no limitation of the expansion of the network when switches of
the SCALANCE X-100 product line are cascaded
Network topology and network configuration
The SCALANCE X-100 switches are typically installed with the
stations to be connected in a control cabinet. They can be mixed
electrically and optically in star and line topologies.
When configuring the network, it is necessary to observe the
following boundary conditions:
•
Length of the TP cable between SCALANCE X switches:
- Max. 100 m with Industrial Ethernet FastConnect products
•
Length of the TP cable between SCALANCE X switch and
Power-over-Ethernet terminal equipment:
- Max. 100 m with Industrial Ethernet FastConnect products
•
Length of the fiber-optic cables:
- Max. 5 km with Industrial Ethernet glass fiber-optic cables
