EL6731 Beckhoff High-performance PROFIBUS DP Master/slave Terminal Modules

1.Overview of the EL6731 Beckhoff

The Beckhoff EL6731 is a high-performance PROFIBUS DP master/slave terminal module designed for industrial automation. It seamlessly integrates with upper-level control systems via EtherCAT bus. This module does not require a PCI slot in a PC and can be directly mounted on a standard DIN rail, providing a flexible and space-saving PROFIBUS network solution.

The core functionality of the EL6731 is similar to a Beckhoff FC3101 PROFIBUS PCI card, but it connects via an EtherCAT terminal module system, eliminating the need for a dedicated PCI slot in the industrial PC and achieving a more space-efficient integration solution.

Protocol and Device Integration: This module can control the full PROFIBUS protocol and can integrate any PROFIBUS device in an EtherCAT terminal network.

High Performance and Precise Synchronization: Thanks to its internally developed PROFIBUS chip, the EL6731 features high-precision isochronous synchronization, particularly suitable for axis control, and provides extended diagnostic functions.

Flexible slave polling: A key feature is that it supports setting different polling rates for different slaves in the network, which enhances the flexibility of system configuration.

2.Core Features:

Supported Protocols: PROFIBUS DP (Standard), PROFIBUS-DP-V1, DP-V2, PROFIBUS MC (Isometric)
Bus Channels: 1 channel
Data Transfer Rate: 9.6 kbaud to 12 Mbaud
Bus Interface: 1 D-Sub 9-pin female connector, electrically isolated
Maximum Number of Slaves: Up to 125 slaves
Data Capacity per Slave: Up to 244 bytes of input/output/parameter/configuration or diagnostic data
Typical Cycle Time: Over 200 μs, supports different DP cycle times per slave (CDL method)
E-bus Current Consumption: Typical 200-240 mA
Operating Temperature: 0 °C to +55 °C

Weight: Approx. 70 grams

The EL6731 is ideal for use in automation systems that require integration of existing PROFIBUS devices or networks into EtherCAT and PC-based control architectures.

Space-saving: Eliminates the need for an industrial PC's PCI slot, enabling a compact control cabinet design.

Seamless integration: Acts as a bridge between EtherCAT and PROFIBUS networks, protecting existing user investments (such as PROFIBUS sensors and actuators) while allowing users to enjoy the advantages of EtherCAT's high-speed communication.

Powerful diagnostics: Provides robust parameter and diagnostic interfaces; error management is configurable for each bus user, facilitating system maintenance and troubleshooting.
