X20IF2792 B&R

X20IF2792 B&R Input module

Product  Description：

The B&R X20IF2792 is a member of the X20 interface module series, which is characterized by its compact design and seamless integration into the B&R automation environment. It serves as a bridge, allowing the X20 system to communicate with external devices via a specific protocol. The module is designed to be inserted into a corresponding interface slot on a CPU or bus controller, rather than sitting on the standard X20 I/O backplane. It provides one physical interface port and is managed through the B&R Automation Studio software.

Product Parameters

The technical specifications of the X20IF2792 define its role in a control system:

• Module Type: X20 Interface Module

• Protocol Support: This module specifically features a PROFIBUS DP Master interface, allowing the X20 system to control PROFIBUS DP slave devices.

• Transmission Rate: Supports all standard PROFIBUS baud rates from $9.6 \text{ kbit/s}$ up to $12 \text{ Mbit/s}$, which is automatically detected or manually configured.

• Connection Type: 9-pin D-sub female connector for PROFIBUS attachment.

• Power Consumption: Typically draws power from the internal bus of the X20 CPU or bus controller, usually around $1.5 \text{ W}$ to $2 \text{ W}$.

• Diagnostics: Equipped with status LEDs (labeled as Status and Error) to indicate the operational state of the PROFIBUS network and the module itself.

• Environmental Limits: Operating temperature range from $0\text{°C}$ to $+55\text{°C}$ for horizontal mounting.

• Isolation: Electrical isolation between the PROFIBUS interface and the X20 system internal electronics to protect against surges and noise.

Product Advantages

One of the key advantages of the X20IF2792 is its System Integration. Because it is part of the X20 system, it is fully integrated into B&R’s Automation Studio, allowing for easy configuration through GSD files and direct mapping of variables. Its Compact Footprint is another benefit, as it adds fieldbus master capabilities without requiring additional DIN rail space beyond the CPU assembly.

The module's High Performance ensures that data exchange between the PROFIBUS network and the CPU is fast and consistent, making it suitable for time-critical applications. Furthermore, the Hot-swappable nature of the X20 system (when used with the appropriate base modules) allows for easier maintenance and reduced downtime during module replacement.

Important Considerations and Precautions

When using the X20IF2792, several precautions are necessary to ensure stable operation. First, Bus Termination is critical; ensure that active termination is applied at both physical ends of the PROFIBUS segment to prevent signal reflections. Second, use only Shielded Twisted Pair Cable specifically rated for PROFIBUS DP to maintain signal integrity in electrically noisy environments.

Third, the Module Placement is restricted to specific interface slots on the X20 CPU; it cannot be placed in a standard I/O terminal block. Fourth, ensure that the GSD Files for all connected slave devices are correctly imported into Automation Studio to avoid configuration errors. Finally, always observe the Bending Radius of the PROFIBUS cable when wiring the D-sub connector to prevent mechanical stress on the module's port.

Product Applications

The X20IF2792 is used in scenarios where a B&R control system needs to manage a legacy or specialized network of PROFIBUS devices.

• Factory Automation: Connecting B&R CPUs to existing PROFIBUS-based motor starters, frequency converters, or remote I/O stations from various manufacturers.

• Process Industry: Interfacing with analytical instruments, flow meters, and valves that utilize the PROFIBUS DP protocol for data exchange.

• Machine Retrofitting: Upgrading an older machine’s control system to B&R while keeping the existing, functioning PROFIBUS slave hardware in place to save costs.

• Automotive Production: Integration into assembly lines where different subsystems communicate via PROFIBUS for coordinated movement and monitoring.
