Product Overview
The Siemens 6AG1195-7HC00-2XA0 Active Bus Module is a compact industrial automation component designed to support the modular architecture of Siemens distributed I/O systems. As an Active Bus Module within the SIPLUS ET 200 product family, it forms part of the infrastructure used to interconnect compatible modules and maintain an organized distributed I/O station.
Distributed I/O technology is widely used in modern factory automation, machine control, process equipment, and infrastructure systems. Instead of routing every field signal to a central control cabinet, distributed I/O stations can be installed closer to sensors and actuators. This reduces field wiring complexity and allows control systems to be constructed from modular components. The active bus infrastructure is an important part of this architecture because it provides the internal system connections required by the installed modules.
The Siemens 6AG1195-7HC00-2XA0 has specified dimensions of 97 × 92 × 30 mm and a weight of 0.127 kg. Its compact design makes it suitable for industrial control cabinets and modular I/O installations where efficient use of available space is important.
The 6AG1195-7HC00-2XA0 is not a standalone PLC, CPU, or conventional signal-processing module. Its function is associated with the internal infrastructure of a compatible distributed I/O station. Therefore, correct selection should always be based on the complete system configuration, including the controller, interface components, I/O modules, bus architecture, power arrangement, and field wiring.

What Is the Siemens 6AG1195-7HC00-2XA0?
The Siemens 6AG1195-7HC00-2XA0 is an Active Bus Module intended for use within a compatible Siemens SIPLUS ET 200 distributed I/O architecture.
In a modular I/O system, multiple electronic modules must operate together as one coordinated station. Digital input modules acquire discrete signals, digital output modules control field devices, and analog modules handle continuous process signals. These electronic components require a common infrastructure for their physical and electrical interconnection.
The active bus module is part of this infrastructure.
Its purpose is therefore different from that of a PLC CPU or an I/O signal module. Instead of executing application logic or directly processing field signals, it supports the internal organization of the distributed I/O station.
This makes the component particularly important when designing or maintaining modular systems in which reliability of the internal bus connection is essential.
Understanding the Active Bus Module
The term Active Bus Module refers to a component that participates in the internal bus architecture of a modular automation station.
In a distributed I/O system, the bus architecture provides the communication path between the individual station components. This allows the controller to exchange process data with the appropriate I/O modules.
A simplified architecture can be represented as:
PLC → Industrial Network → I/O Interface → Active Bus Infrastructure → I/O Modules → Field Devices
The exact system architecture depends on the selected Siemens components, but the principle remains the same: the bus infrastructure connects the individual modules into a coordinated automation station.
This modular approach provides significant advantages for industrial system designers.
Function and Working Principle
The 6AG1195-7HC00-2XA0 supports several aspects of distributed I/O system construction.
Internal Module Interconnection
The active bus module provides part of the infrastructure required for compatible modules to operate together.
Instead of treating every I/O module as an isolated device, the modular station allows multiple components to share a common system architecture.
Bus Infrastructure
Reliable internal communication is essential for distributed I/O.
The active bus structure allows data and system information to be exchanged between the station’s components and the external automation controller.
Modular Expansion
A modular bus architecture makes it easier to construct I/O stations according to the application requirements.
For example, a machine may require a combination of:
- Digital input modules
- Digital output modules
- Analog input modules
- Analog output modules
- Technology modules
- Communication modules
- Power-related components
The modular infrastructure allows the station to be configured around these requirements.
Maintenance Support
The modular design also simplifies maintenance. A technician can identify individual system components and investigate them separately instead of replacing the complete I/O station.
Role in Distributed Automation
The Siemens 6AG1195-7HC00-2XA0 occupies an infrastructure position within a distributed automation system.
A complete system may contain:
- PLC controller
- Industrial Ethernet infrastructure
- Distributed I/O interface
- Active bus components
- Digital I/O modules
- Analog I/O modules
- Power modules
- Terminal components
- Sensors
- Actuators
- HMI devices
- Supervisory control systems
The PLC executes the control logic. The network transfers information between the controller and remote I/O. I/O modules interface directly with field devices, while bus infrastructure supports the internal organization of the I/O station.
This separation of functions provides a scalable approach to industrial automation.
Why the Internal Bus Is Important
The internal bus is an important part of any modular distributed I/O system.
Consider a typical process signal:
Sensor → I/O Channel → Internal Bus → I/O Interface → Network → PLC
A problem with the sensor normally affects one signal.
A problem with an I/O module may affect one group of channels.
However, an infrastructure problem can potentially affect multiple modules simultaneously.
This is why the active bus module should be considered during troubleshooting when several I/O modules show communication or availability problems at the same time.
Industrial Applications
The Siemens 6AG1195-7HC00-2XA0 Active Bus Module can be incorporated into compatible SIPLUS ET 200 distributed automation systems.
Factory Automation
Distributed I/O is commonly used in:
- Assembly lines
- Packaging machinery
- Conveyor systems
- Automated production cells
- Robotic systems
- Material handling equipment
- Inspection machines
Remote I/O stations can be positioned close to the equipment they control, reducing field wiring requirements.
Machine Building
Machine builders can use modular distributed I/O to create standardized control architectures.
A common platform can be adapted to different machine configurations by changing the required I/O modules.
Process Automation
Distributed I/O can be used near:
- Pumps
- Valves
- Flow instruments
- Pressure sensors
- Temperature transmitters
- Level measurement equipment
This approach can simplify field wiring and improve system organization.
Water and Wastewater
Distributed control stations can monitor and control equipment throughout treatment facilities, including pumps, valves, motors, and instrumentation.
Energy and Infrastructure
The modular I/O concept can also be used in utility systems, equipment monitoring, and infrastructure automation.
Installation Considerations
The active bus module should be installed according to the requirements of the compatible Siemens distributed I/O architecture.
Before installation, engineers should confirm:
