BECKHOFF CX2500-M310 PROFIBUS Fieldbus Master Module

Description

The BECKHOFF CX2500-M310 is a high-performance PROFIBUS master module designed for integration with the CX20xx series of Embedded PCs. Utilizing a high-speed PCI Express interface to connect directly to the CPU unit, this extension module enables CX2020, CX2030, CX2040, and other compatible controllers to act as master stations on a PROFIBUS network. It provides a reliable and direct communication path for distributed I/O systems and field devices.

This module supports PROFIBUS DP, DP-V1, and DP-V2 (MC) protocols, offering comprehensive fieldbus communication configurations. It features advanced configuration options, including the ability to define distinct DP cycle times for individual slave devices and customize error management profiles. This level of control ensures precise system performance and efficient handling of communication faults across complex network architectures.

Features

• Compatible with BECKHOFF CX20xx series Embedded PCs via a high-speed PCI Express interface.
• Supports standard PROFIBUS DP and DP-V1 protocols.
• Equipped with a standard 9-pin D-sub socket for direct bus connection.
• Supports network baud rates ranging from 9.6 kbaud up to 12 Mbaud.
• Capable of controlling up to 125 PROFIBUS slave devices simultaneously.
• Allows up to 244 bytes of input, output, parameter, configuration, or diagnostic data per slave.
• Configurable DP cycle times independent for each slave device.
• Freely definable error management per user/slave connection.

Applications

• Integration of PROFIBUS-compliant field devices and drives into CX20xx PC-based control architectures.
• Distributed I/O expansion in factory automation and machinery assembly lines.
• Upgrade paths for existing systems transitioning from legacy PLCs to PC-based control while preserving existing PROFIBUS cabling and infrastructure.

Installation Guidelines

1. Verify that the main CX20xx Embedded PC system is completely powered down and de-energized before mounting.
2. Align and securely connect the CX2500-M310 module to the left-hand side expansion interface of the CX20xx CPU block, ensuring the PCI Express connector is correctly mated.
3. Tighten any physical mounting locks or locking mechanisms to ensure a secure and stable mechanical unit.
4. Connect the PROFIBUS segment cable to the 9-pin D-sub connector on the front face of the module.
5. Ensure proper grounding and shielding procedures are followed for the PROFIBUS cable to minimize electromagnetic interference.
6. Power up the CX20xx system and utilize TwinCAT to scan, configure, and initialize the PROFIBUS master network.
