Product Overview
The Siemens 6AG1195-7HG00-2XA0 Active Bus Module is a compact industrial automation component designed to support the internal infrastructure of compatible Siemens distributed I/O systems. As an active bus module, it provides the necessary interconnection structure between compatible modules within a modular automation station, helping maintain an organized and reliable internal communication architecture.
Distributed I/O systems are widely used in modern manufacturing, machine automation, process control, and infrastructure applications because they allow I/O electronics to be positioned closer to field devices. Instead of routing every sensor and actuator signal back to a central PLC cabinet, distributed stations can collect signals locally and exchange process data with the controller through an industrial communication network.
The 6AG1195-7HG00-2XA0 belongs to this type of modular station infrastructure. It is not intended to replace a PLC CPU or conventional analog/digital I/O module. Instead, its role is associated with the internal bus and modular connection structure of a compatible station.
The listed dimensions are 97 × 92 × 30 mm, and the listed weight is 0.145 kg. Its compact construction is suitable for industrial control cabinets where efficient use of installation space, modularity, and maintainability are important.

What Is the Siemens 6AG1195-7HG00-2XA0?
The Siemens 6AG1195-7HG00-2XA0 is an Active Bus Module used as part of a compatible modular distributed I/O architecture.
In an industrial automation system, an I/O station normally consists of multiple layers of hardware. The controller executes the application program, the communication interface connects the station to the industrial network, and individual I/O modules handle field signals. Between these functional modules, a reliable internal connection structure is required.
The active bus module contributes to this internal structure.
A simplified architecture can be represented as:
PLC → Industrial Network → Distributed I/O Station → Active Bus Infrastructure → I/O Modules → Field Devices
This architecture allows automation engineers to build flexible I/O stations containing different types of modules according to the requirements of the machine or process.
The active bus module therefore performs an infrastructure role rather than acting as a standalone controller.
Active Bus Module Function
The main purpose of an active bus module is to support the internal communication and modular organization of the compatible I/O station.
Its function can be understood through several basic responsibilities:
- Provides part of the internal bus architecture
- Supports module-to-module interconnection
- Helps establish an organized distributed I/O structure
- Supports modular station construction
- Facilitates maintenance and module replacement
- Contributes to reliable internal data communication
- Helps simplify the physical organization of automation hardware
The exact internal electrical implementation depends on the specific Siemens station architecture in which the 6AG1195-7HG00-2XA0 is installed.
For this reason, engineers should always verify the intended station configuration before installing or replacing an active bus module.
Working Principle
An active bus module operates as part of the backplane or internal bus infrastructure of a distributed I/O station.
When compatible modules are assembled into the station, the internal bus provides the communication path required for exchanging information between the station interface and the individual I/O modules.
For example, a digital input module may acquire the state of a proximity switch. An analog input module may receive a process measurement from a transmitter. Output modules may control valves, relays, contactors, or other actuators.
The active bus infrastructure allows these modules to participate in the overall station architecture.
The simplified information flow is:
Field Signal → I/O Module → Internal Bus → Station Interface → Controller
For control commands, the direction is reversed:
Controller → Station Interface → Internal Bus → Output Module → Actuator
The active bus module is therefore an important part of the communication path even though it does not normally execute the user control program.
Role in Distributed Automation Systems
The 6AG1195-7HG00-2XA0 can be considered a station infrastructure component in a distributed automation system.
A typical automation architecture contains:
Field Devices
Sensors, switches, transmitters, valves, motors and actuators interact directly with the physical process.
I/O Modules
Digital and analog modules acquire field information or provide control outputs.
Bus Infrastructure
Active bus modules and related station components establish the internal modular connection between the I/O electronics and station interface.
Industrial Network
The distributed station communicates with the PLC through an industrial communication network.
Controller
The PLC executes application logic based on the acquired process information.
HMI and SCADA
Supervisory systems provide visualization, alarms, diagnostics, trends, and operator control.
This layered architecture allows industrial automation systems to become more modular and easier to maintain.
Importance of Reliable Bus Infrastructure
The reliability of a distributed I/O system does not depend only on the I/O modules themselves. The station infrastructure also plays an important role.
If the internal bus connection is unstable, communication with several modules may be affected simultaneously.
A properly installed active bus infrastructure helps provide:
- Stable module communication
- Consistent station operation
- Modular expansion capability
- Organized cabinet construction
- Easier maintenance
- Faster module replacement
- Reduced wiring complexity
This is particularly important in large industrial systems where a single distributed station may contain many I/O points.
Industrial Applications
Factory Automation
The Siemens 6AG1195-7HG00-2XA0 can be integrated into compatible distributed I/O stations used in factory automation.
Typical systems include:
- Assembly lines
- Automated production equipment
- Packaging machinery
- Machine tools
- Material handling systems
- Inspection equipment
- Robotic support systems
Distributed I/O allows control signals to be collected closer to the equipment they serve.
Process Automation
Distributed I/O architectures are also useful in process-oriented installations.
Potential applications include:
- Water treatment
- Chemical processing
- Utility systems
- Industrial production plants
- Process skids
- Equipment monitoring
Local I/O stations can simplify the collection of signals from equipment distributed across a facility.
Conveyor and Material Handling
Conveyor systems can contain sensors and actuators spread across considerable distances. Distributed I/O stations help organize these signals into local control zones.
Packaging Equipment
Packaging machines typically contain numerous switches, sensors, motors, valves, and actuators. Modular distributed I/O provides a practical method of organizing these control signals.
Infrastructure Automation
Industrial facilities can use distributed I/O stations for equipment monitoring and control when the selected Siemens automation architecture supports the required configuration.
System Integration
The 6AG1195-7HG00-2XA0 should be considered together with the complete automation station rather than as an independent device.
A typical configuration may include:
- Siemens PLC
- PROFINET communication infrastructure
- ET 200SP station components
- Active bus modules
- Base units
- Digital input modules
- Digital output modules
- Analog input modules
- Analog output modules
- Technology modules
- Power-related components
- HMI panels
- SCADA software
The actual configuration depends on the application and required I/O functions.
PLC Integration
A distributed I/O station allows the PLC to exchange process data with remote I/O electronics.
A simplified control architecture is:
Sensor → Input Module → Active Bus Infrastructure → Station Interface → PLC
The PLC processes the received information and determines the required control action.
For an output:
PLC → Station Interface → Active Bus Infrastructure → Output Module → Actuator
The active bus module contributes to the internal station communication structure that makes this modular architecture possible.
HMI and SCADA Integration
The distributed I/O station can also become part of a larger supervisory control architecture.
An HMI or SCADA system may display:
- Input states
- Output states
- Process values
- Equipment status
- Station diagnostics
- Communication conditions
- Alarm information
- Maintenance information
This creates a complete automation chain from the physical process through the I/O station and PLC to the operator interface.
The 6AG1195-7HG00-2XA0 does not replace the HMI or SCADA system; instead, it supports the underlying station infrastructure required for distributed I/O operation.
