Compact variants for Layer 2 networking of plants

The SCALANCE XC-300 product line (as a successor to the SCALANCE X-300 compact switch series) and SCALANCE XCM-300 give you access to compact Industrial Ethernet Switches for the design of electrical and optical line, ring, and star structures in your network.


Thanks to the compact SIMATIC S7-1500 design, the SCALANCE XC-300 and XCM-300 managed switches are perfectly suited for rack installation. With transmission rates of up to 10 Gbit/s and a large number of ports, SCALANCE XC-300 and XCM-300 meet high requirements for network availability. The switches in the SCALANCE XC-300 series are also available as an EEC version.

Typical uses

The SCALANCE XC-/XCM-300 Industrial Ethernet Switches can be used in the aggregation or control level of the network and enable high-performance plant networks. Wherever high transmission rates are required, the SCALANCE XC/XCM-300 Layer 2 Switches connect plant components and also distributed devices in the field. A special advantage is the function extender interface of the Switches for connection to the local processing engine – called SCALANCE LPE

Rugged and flexible rackmount switch

SCALANCE XR-300 and SCALANCE XRM‑300 rackmount switches in 19-inch rack format can be used to design electrical and/or optical line, ring and star structures with a transmission rate of up to 10 Gbit/s.


These rackmount switches take charge of networking with distributed field devices at both field level and control level and ensure high plant availability with far-reaching diagnostic options and high transmission rates.

Typical uses

The SCALANCE XR-/XRM-300 Industrial Ethernet Switches can be used in the network at the aggregation and control level, and make high-performance system networks a possibility. Wherever high transmission rates are necessary, the SCALANCE XR-/XRM-300 Layer 2 switches network plant units and also distributed field devices.


The SCALANCE XR-300EEC (Enhanced Environmental Conditions) rackmount switches also feature a high noise immunity and can be used in an extended temperature range (-40°C to +80°C), for example, in energy automation applications to fulfill the requirements of IEC 61850-3/IEEE 1613.

Cost-optimized rackmount switch with small mounting depth

The cost-optimized managed SCALANCE XR 300WG (work group) 19" rackmount switches have a small mounting depth, which means two switches can be installed on both sides to save space in the control cabinet.

Typical uses

SCALANCE XR-300WG rackmount ethernet switches are ideally suited for a wide variety of industry-related applications and provide high availability in the network thanks to features like redundancy mechanisms (MRP) and virtual LANs (VLAN). They feature up to 28 Gigabit ports and combo ports and can also bridge long distances due to their fiber-optic interfaces (SFP).

Compact variants are available with up to 20 electrical or three optical ports (ST/BFOC, SC) or semi-modular variants with up to eight electrical or optical ports (configurable via media modules) for distances up to 26 km. The switches offer various redundancy mechanisms like the media redundancy protocol (MRP) and can be replaced in the event of a fault with no special skills thanks to the C-PLUG removable storage media.

Typical uses

SCALANCE X-300 Ethernet switches let you design networks in both the field and control areas, wherever high network availability, extensive diagnostic options, and high transmission speeds are required. The switches are designed for use in control cabinets and meet the requirements of protection class IP30.

FastConnect – a cabling system gets the hang

Structured cabling is the basis of an industrial bus system or network and must fulfill much higher requirements than cabling in the office area. Stringent demands are placed on the installation of cables in the industrial environment. For the SCALANCE X-300 switches in rackmount and compact design, Siemens offers FastConnect, a system that fulfills all these requirements: On-site assembly – quick, easy and error-free.

PLUGs for network components

Swap devices easily with no need for special knowledge: The C-PLUG, KEY-PLUG, and SCALANCE CLP removable storage media save the configuration data from your SCALANCE devices. Remove PLUG, install replacement device, insert PLUG – and the new device is ready to go! The KEY-PLUGs include all the functions of the C-PLUG and also enable specific functions like the iFeatures in SCALANCE X-300 rackmount switches and compact variants.

Plug-in transceivers

Plug-in transceivers allow you to flexibly equip network components of the SCALANCE family with a corresponding SFP slot for optical connections. 

Media modules for SCALANCE X-300 rackmount switches

The MM992-2VD media module (variable distance), which is plugged into a modular SCALANCE X-300 rackmount switch, can use any type of two-wire cable for Ethernet connections up to 1,000 m. This includes, for example, land lines, and lines through fireproof bulkheads or along pipelines, which can be very difficult to replace. With the media module MM992-2VD you can also connect PROFINET routes up to 500 m in length with eight-wire copper cables.
