X20IF2792 B&R

Product Dimensions：

The X20IF2792 is a standardized interface module that plugs into the X20 system's interface slots. It is equipped with a standard 9-pin D-sub female connector for PROFIBUS communication. The module is designed to handle complex automation tasks where a B&R control system needs to manage high-speed data exchange with third-party drives, sensors, or remote I/O that utilize the PROFIBUS DP protocol. It features integrated LEDs for status monitoring and is fully integrated into the B&R Automation Studio software environment for configuration and diagnostics.

Product Parameters

• Module Type: Interface module for X20 System

• Protocol: PROFIBUS DP-V0 / DP-V1 (Master)

• Interface: 1x RS-485 interface, electrically isolated

• Connection: 9-pin D-sub female connector

• Transfer Rate: Supports all standard PROFIBUS baud rates from $9.6 \text{ kbit/s}$ up to $12 \text{ Mbit/s}$

• Max Number of Slaves: Up to 125 slaves can be addressed by the master

• Bus Length: Maximum $1200 \text{ m}$ (depending on the transfer rate and cable quality)

• Power Consumption: Typically $2.0 \text{ W}$ provided via the X20 backplane

• Status Indicators: Integrated LEDs for Module Status and Network Activity

• Electrical Isolation: Interface is galvanically isolated from the X20 backplane

Product Advantages

A primary advantage of the X20IF2792 is its Seamless Integration into the B&R ecosystem. Users can configure the entire PROFIBUS network within B&R Automation Studio using GSD files, which simplifies the engineering process significantly. The High Transfer Performance of up to $12 \text{ Mbit/s}$ ensures that the module can handle time-critical data for motion control or rapid sensing applications.

Furthermore, the Galvanic Isolation protects the internal electronics of the controller from electrical noise and voltage spikes originating in the fieldbus cabling. Its Compact Form Factor allows for the addition of powerful networking capabilities without increasing the footprint of the control cabinet significantly, as it fits directly into existing X20 interface slots.

Important Considerations and Precautions

When implementing the X20IF2792, users must pay close attention to Bus Termination. Each end of the PROFIBUS segment must be equipped with an active terminator; failure to do so can lead to signal reflections and communication errors. It is also vital to use Certified PROFIBUS Cables (Type A) to ensure that the impedance is correct for the high-speed data rates.

Regarding installation, the module should only be inserted or removed when the Power is Switched Off to prevent damage to the backplane or the interface card itself. For reliable operation in high-interference environments, ensure the D-sub connector housing is properly shielded and the shield is connected to the functional ground of the cabinet. Finally, be aware of the I/O Data Limits of the PROFIBUS standard; exceeding the maximum data length for a single slave or the entire bus can result in performance degradation.

Product Applications

The X20IF2792 is widely used in scenarios where a B&R control system acts as the central intelligence in a multi-vendor environment.

• Drive Integration: Controlling and synchronizing frequency converters or servo drives from manufacturers like Siemens or Danfoss that use PROFIBUS.

• Factory Automation: Connecting to modular remote I/O stations located across a large manufacturing facility to reduce wiring costs.

• Process Industry: Interfacing with analytical instruments, flow meters, and pressure transmitters in chemical or food and beverage plants.

• Machine Tooling: Managing peripheral devices such as tool changers or cooling systems that operate on a serial fieldbus.

• Packaging Machinery: Coordinating multiple localized controllers and sensors on a high-speed production line.
