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
Protection Rating: IP20
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.
