Siemens 6AG1106-2BB00-7AC2 — Technical Specifications, Product Introduction, Applications, Advantages, and Related Models

1. Product Overview

The 6AG1106-2BB00-7AC2 is a SIPLUS NET SCALANCE XC106-2 industrial Ethernet switch. It is an unmanaged Layer 2 switch designed to connect industrial Ethernet devices through copper and multimode fiber-optic interfaces.

The unit provides six 10/100 Mbps RJ45 Ethernet ports and two 100 Mbps multimode fiber ports with BFOC connectors. This combination allows copper-connected equipment to communicate across an optical network segment, while the additional Ethernet ports provide local connectivity for multiple industrial devices.

The product is designed for demanding industrial environments. Its conformal-coated electronics and specified operating temperature range of -40°C to +70°C make it suitable for applications where temperature variation and environmental exposure are important selection factors.

Unlike a programmable controller, this switch does not execute automation programs. Its role is to forward Ethernet traffic between connected devices, helping controllers, remote I/O, drives, operator panels, and other networked equipment exchange information.

2. Brand and Product Series

The SCALANCE XC106-2 is intended for industrial networks that need straightforward Ethernet connectivity and both copper and optical ports. The SIPLUS version adds environmental protection features for installations that operate under more demanding conditions than a typical office network.

3. Detailed Technical Specifications

The following table summarizes the main electrical, mechanical, networking, and environmental characteristics of the 6AG1106-2BB00-7AC2.

3.1 Ethernet ports and data rates

The switch provides six RJ45 electrical Ethernet ports operating at 10 or 100 Mbps. These ports can connect compatible devices such as PLCs, industrial PCs, remote I/O stations, operator panels, and other Ethernet-enabled equipment.

The two optical ports support 100 Mbps multimode fiber connections using BFOC connectors. They are useful when part of the network needs to use fiber instead of copper cabling.

The ports do not make the switch an eight-port copper switch: the interface arrangement consists of six copper Ethernet ports and two optical ports.

3.2 Power requirements

The unit uses a nominal 24 V DC supply and supports an input range of 9.6–31.2 V DC. Its redundant supply capability can help maintain operation if one of two appropriately configured power feeds fails.

Redundant power does not automatically make the entire network redundant. The power feeds, upstream network connections, and connected equipment must also be designed appropriately if the application requires high availability.

3.3 Industrial environmental specifications

The specified operating temperature range is -40°C to +70°C. This is a significant feature for installations exposed to cold startup conditions, elevated cabinet temperatures, or substantial ambient-temperature variation.

The conformal coating provides additional protection to the electronics against certain environmental influences. It does not make the enclosure waterproof, and it does not eliminate the need for correct installation and environmental protection.

3.4 Dimensions and weight

The unit measures 60 × 147 × 125 mm and has a listed net weight of 0.815 kg.

These measurements describe the device rather than its shipping packaging. When designing a control cabinet, allow extra space for RJ45 connectors, optical connectors, power wiring, grounding, ventilation, and maintenance access.

4. Product Introduction

4.1 A compact industrial Ethernet switch

The 6AG1106-2BB00-7AC2 is intended for industrial communication networks that need a compact, unmanaged switch with both electrical and optical Ethernet interfaces.

In a typical industrial network, different devices may be connected using copper Ethernet within a control cabinet, while a fiber link carries data between cabinets or production areas. This switch provides a way to combine those connections in a single device.

Its role is to receive Ethernet frames through one port and forward them to the appropriate connected port. It does not need a user-defined routing configuration for ordinary switching operation.

4.2 Copper and fiber in one device

One of the main characteristics of the SCALANCE XC106-2 is its mixed interface arrangement.

The six RJ45 ports accommodate conventional copper Ethernet connections. The two multimode fiber ports provide optical connectivity for compatible network segments.

This arrangement is useful when a machine has several local Ethernet devices but also needs an optical connection to another cabinet, cell, or section of a factory.

Fiber-optic transmission can also reduce the effect of electromagnetic interference along the optical segment, which can be beneficial in industrial environments with motors, contactors, and drive equipment.

4.3 Unmanaged operation

The switch is designed for applications that do not require a managed-switch configuration interface.

After the correct power supply and network connections are installed, the switch can perform basic Ethernet forwarding without requiring the user to configure VLANs, routing, or advanced switch-management settings.

This simplicity is helpful for small machine networks and straightforward industrial communication arrangements. However, an unmanaged switch does not offer the same configuration and monitoring capabilities as a managed industrial switch.

4.4 SIPLUS environmental design

The SIPLUS version is designed for applications with demanding environmental requirements. Its specified temperature range and conformal coating make it suitable for certain installations where ordinary commercial networking equipment may not meet the required conditions.

Environmental suitability should always be assessed for the actual installation. The IP20 rating means that the device is intended for protected mounting rather than direct exposure to water or uncontrolled outdoor conditions.

4.5 Diagnostic and signaling functions

The unit provides LED diagnostics and an error-signaling contact with a set/reset pushbutton.

These functions can help maintenance personnel identify basic operating or fault conditions and provide an indication to a compatible monitoring circuit.

The signaling contact is useful where a system needs a simple way to communicate a device-status or fault indication. Its integration should follow the device’s wiring and configuration instructions.

5. Main Applications

5.1 Factory automation networks

The switch can connect Ethernet-enabled automation equipment across a production line. Typical devices include PLCs, distributed I/O, operator panels, industrial PCs, and compatible drives.

By providing several copper ports and two optical interfaces, it can accommodate local machine connections alongside fiber links to other network segments.

5.2 Connecting separate control cabinets

Industrial machines often have multiple cabinets distributed along a line or positioned near different equipment groups.

The switch can connect local copper devices while providing optical ports for communication with another compatible network segment. This can reduce reliance on long copper Ethernet runs between separated areas.

5.3 Networks in electrically noisy environments

Fiber-optic links are useful in environments where electrical noise can affect copper communication cables.

For example, an optical connection between two cabinets may be preferable when the route passes through an area containing high-power motors or drive equipment.

The fiber segment is not susceptible to electromagnetic interference in the same way as a copper cable. The electrical sections still require appropriate cable selection, routing, and installation practices.

5.4 Distributed I/O and PLC communication

A PLC may need to exchange data with remote I/O stations positioned around a machine. The switch can provide network connections for compatible Ethernet devices and help organize communication between equipment groups.

The actual network topology must follow the requirements of the controller, I/O equipment, and communication protocol in use.

5.5 Drive and motor-control networks

Modern drives and motor-control devices may exchange commands, status information, diagnostic data, and process information over industrial Ethernet.

The XC106-2 can provide network connectivity for compatible Ethernet-based equipment. It does not itself control motor speed or execute motion-control logic; those functions remain with the drive and automation controller.

5.6 Fiber-based connections between production areas

When a network needs to connect equipment in different parts of a facility, fiber can be useful for the longer or electrically noisy section of the link.

The switch’s multimode optical interfaces provide a way to integrate such links, provided the fiber type, connector, optical characteristics, and distance are compatible with the connected equipment.

5.7 Industrial maintenance and replacement

The model can also be used as a replacement for a compatible device in an existing installation.

When replacing an industrial switch, check the number and type of ports, fiber connector, data rate, operating temperature, power requirements, mounting, and diagnostic features. A switch with a similar port count may still be unsuitable if its optical interface or environmental rating differs.

6. Product Advantages

6.1 Mixed copper and optical connectivity

The combination of six RJ45 ports and two multimode fiber ports is one of the product’s most practical features.

It allows local devices to use copper Ethernet while providing optical connections for compatible network segments. This can simplify the network layout where both transmission media are needed.

6.2 Wide operating-temperature range

The specified range of -40°C to +70°C makes the device suitable for a wider range of industrial temperature conditions than equipment intended only for ordinary indoor environments.

This can be important in industrial cabinets exposed to low ambient temperatures or elevated operating temperatures. Actual suitability still depends on the installation and environmental requirements.

6.3 Conformal-coated electronics

The conformal coating provides additional protection against certain environmental influences affecting electronic assemblies.

This can be beneficial in industrial settings where humidity, airborne contaminants, or other environmental stresses are concerns. It should not be interpreted as a guarantee of operation in every harsh environment.

6.4 Redundant power capability

The redundant supply arrangement can help improve availability when the device is powered from two appropriately configured sources.

For installations where a power-supply failure must not immediately interrupt network switching, this feature can form part of a wider reliability strategy.

6.5 Simple commissioning

As an unmanaged switch, the device does not require the same configuration process as a managed switch.

This makes it appropriate for small industrial networks where basic switching is sufficient and there is no requirement for advanced network administration.

6.6 Built-in diagnostic indications

LED diagnostics provide a convenient way to check basic operating and connection states. The error-signaling contact can also be integrated into a suitable monitoring arrangement.

These features help maintenance personnel begin troubleshooting without immediately requiring a network-management tool.

6.7 Compact industrial mounting

At 60 mm wide, the unit can be fitted into many industrial control cabinets without occupying excessive panel width.

Its supported mounting arrangements provide flexibility for new installations and compatible replacement projects.

6.8 Suitable for mixed network layouts

The product can help bridge local copper Ethernet connections and optical network segments within an industrial system.

This is useful when upgrading a machine network incrementally rather than replacing all cabling and connected equipment at once.

7. Five Related Models

The following models are related to the SIPLUS NET SCALANCE family. They cover different port counts, optical arrangements, and switching requirements. They are not automatically interchangeable with the 6AG1106-2BB00-7AC2.

The dimensions and weights of these related models have not been confirmed here. They are marked for verification rather than estimated from the XC106-2 enclosure.

7.1 6AG1206-2BB00-7AC2 — SCALANCE XC206-2

This model is worth considering when an industrial network needs a different port arrangement within the same general environmental product family.

Before choosing it, compare the number of copper ports, optical interfaces, fiber type, and network topology with the original XC106-2. A similar family name does not guarantee identical port assignments.

7.2 6AG1206-2BS00-7AC2 — SCALANCE XC206-2SFP

The SFP-oriented variant is relevant when the network design requires compatible pluggable optical interfaces.

The choice of SFP module, fiber type, connector, wavelength, and link distance must match the equipment at the other end. It should not be treated as a direct replacement for a BFOC-based device without checking optical compatibility.

7.3 6AG1208-0BA00-7AC2 — SCALANCE XC208

The XC208 family is a potential alternative for applications that need a different number of Ethernet connections.

It is useful to consider when the number of connected devices is changing or when the network layout requires a different port arrangement. Confirm the precise interface configuration before ordering.

7.4 6AG1212-2BB00-4AA3 — SCALANCE X 212-2

This model is relevant to industrial networks requiring another combination of copper and optical interfaces.

Its suitability depends on the required port count, optical specifications, environmental limits, and power arrangement. The exact data sheet should be checked before treating it as an alternative to the XC106-2.

7.5 6AG1216-4BS00-7AC2 — SCALANCE XC216-4C

The XC216-4C family is worth evaluating for larger industrial network layouts that require more connection options.

It may be relevant when the original switch’s port count is insufficient. However, the exact hardware variant and interface mix should be verified, particularly if fiber connectivity is an essential part of the network design.

8. Five Other Popular Models from the Same Brand

The following models cover commonly used industrial networking and automation equipment. They are useful for broader system planning, but they do not all perform the same function as the XC106-2.

How these models compare

6GK5005-0BA00-1AB2 — SCALANCE XB005

This model is suitable when a small unmanaged switch with five copper Ethernet ports is sufficient. It is not a direct substitute for the XC106-2 if the installation requires two multimode fiber ports.

6GK5008-0BA10-1AB2 — SCALANCE XB008

The eight-port copper arrangement may be useful when several Ethernet devices need to be connected locally. Confirm that the lack of the required optical interfaces does not create a limitation in the network design.

6GK5208-0BA00-2AC2 — SCALANCE X208

A switch in this category is relevant when the network requires switching capabilities beyond a simple unmanaged arrangement. The exact management features and interface configuration must be checked against the intended network requirements.

6ES7214-1AG40-0XB0 — SIMATIC S7-1200

This programmable controller performs automation logic and communicates with compatible field devices. It can work within an industrial Ethernet network, but it does not replace the switching function of the XC106-2.

6EP1333-2BA20 — SITOP power supply

An industrial power supply may be needed to provide control power to compatible automation equipment. Its output rating and electrical characteristics must match the load and installation design.

9. Installation and Maintenance Recommendations

9.1 Confirm the power arrangement

Use a compatible 24 V DC supply and remain within the specified input-voltage range of 9.6–31.2 V DC.

If redundant power is required, use an appropriately designed arrangement with suitable protection and wiring. Verify the polarity and terminal assignments before energizing the equipment.

9.2 Check the fiber-optic interface

The optical ports use multimode fiber with BFOC connectors. Confirm that the cable and the equipment at the other end use compatible interfaces.

The link distance must remain within the supported optical specifications. Do not assume that every multimode cable type or connector arrangement will work with every 100 Mbps optical interface.

9.3 Allow sufficient cabinet space

The device measures 60 × 147 × 125 mm. Leave additional room for cables, connectors, power terminals, ventilation, and access during maintenance.

The stated dimensions do not include the clearance needed to install or remove cables.

9.4 Observe environmental limits

The unit is specified for operation from -40°C to +70°C, with an IP20 protection rating.

The device should be installed in an environment appropriate for IP20 equipment. If it is placed inside an enclosure, assess the enclosure’s temperature, ventilation, condensation risk, and protection against dust and water.

9.5 Use the diagnostic indicators

When troubleshooting a network problem, inspect the power indication, port status LEDs, and error-signaling function.

Check the physical link before investigating higher-level communication settings. A loose fiber connector, incorrect cable type, or missing power supply can interrupt communication even when the connected controller is functioning normally.

9.6 Verify compatibility before replacement

Before replacing an XC106-2, compare the replacement device’s port count, connector type, fiber specification, power requirements, mounting, temperature range, and diagnostic features.

A newer or more powerful switch is not necessarily a suitable replacement if the optical interface or environmental characteristics differ.
