Switches are active network components that specifically dis-

tribute data to the relevant addressees. SCALANCE X is the 

modern range of Industrial Ethernet switches from SIMATIC NET. 

The SCALANCE X family comprises product lines that comple-

ment each other and are carefully tuned to the specific automa-

tion task.

■

The products referred to below from the SCALANCE X-400, 

X-300, X-200 IRT and X-200 ranges are suitable for use in 

SIMATIC PCS 7 systems.

SCALANCE X-400 switches are suitable for designing a plant 

bus and OS-LAN (terminal bus) with an electrical or optical 

Gigabit ring technology (non-redundant and redundant rings).
• SCALANCE X414-3E with 2 Gigabit Ethernet ports (electri-

cal/optical), 12 electrical FastEthernet ports and optionally 

4 optical FastEthernet ports (BFOC); can be expanded by ex-

tender module with 8 electrical or 8 optical FastEthernet ports 

(BFOC)

• SCALANCE X408-2 with 4 Gigabit Ethernet ports (electrical/

optical) and 4 FastEthernet ports (electrical/optical)

Both versions permit a maximum communications performance, 

in particular with very large plants with comprehensive quantity 

frameworks and expansive communication networks.

SCALANCE X-300 switches can be used to implement Industrial 

Ethernet structures with a line, star or ring topology (non-redun-

dant and redundant rings) with transmission rates up to 

1000 Mbit/s.
• SCALANCE X310 with 3 electrical Gigabit Ethernet RJ45 ports 

and 7 electrical FastEthernet RJ45 ports

• SCALANCE X308-2 with 2 optical Gigabit Ethernet SC ports 

for glass multimode FO cables, 1 electrical Gigabit Ethernet 

RJ45 port and 7 electrical FastEthernet RJ45 ports

• SCALANCE X308-2LD with 2 optical Gigabit Ethernet SC 

ports for glass multimode FO cables, 1 electrical Gigabit 

Ethernet RJ45 port and 7 electrical FastEthernet RJ45 ports

SCALANCE X-200 IRT switches are used for Industrial Ethernet 

structures with a line, star or ring topology (non-redundant and 

redundant rings) with transmission rates up to 100 Mbit/s.
• SCALANCE X204 IRT with 4 electrical RJ45 ports
• SCALANCE X202-2 IRT with 2 electrical RJ45 ports and 

2 optical BFOC ports for glass multimode FO cables

• SCALANCE X202-2P IRT with 2 electrical RJ45 ports and 

2 POF (polymer optical fiber) ports

• SCALANCE X201-3P IRT with 1 electrical RJ45 port and 

3 POF  ports

• SCALANCE X200-4P IRT with 4 POF ports

SCALANCE X-200 switches are suitable for Industrial Ethernet 

structures with a line, star or ring topology with transmission 

rates up to 100 Mbit/s (non-redundant and redundant rings). 

However, they do not have a standby redundancy functionality 

(see table with product characteristics).
• SCALANCE X208 with 8 electrical RJ45 ports
• SCALANCE X204-2 with 2 optical glass FO ports and 

4 electrical RJ45 ports

• SCALANCE X224 with 24 electrical RJ45 ports
• SCALANCE X216 with 16 electrical RJ45 ports
• SCALANCE X208 with 8 electrical RJ45 ports
• SCALANCE X204-2 with 4 electrical RJ45 ports and 2 optical 

BFOC ports for glass multimode FO cables 

• SCALANCE X212-2 with 12 electrical RJ45 ports and 2 optical 

BFOC ports for glass multimode FO cables

• SCALANCE X212-2LD with 12 electrical RJ45 ports and 

2 optical BFOC ports for glass singlemode FO cables

• SCALANCE X206-1LD with 6 electrical RJ45 ports and 

1 optical BFOC port for glass singlemode FO cables
