EL6731 Beckhoff High-performance PROFIBUS DP Master/slave Terminal
Modules
The Beckhoff EL6731 is a high-performance PROFINET I/O communication terminal designed to connect Beckhoff’s EtherCAT-based automation systems
directly to PROFINET IO networks. As a key gateway device in heterogeneous industrial environments,
the EL6731 enables seamless data exchange between EtherCAT masters (e.g., TwinCAT PLCs) and PROFINET controllers from Siemens, Rockwell, Schneider, and other major vendors—making
it an essential component for integrating Beckhoff I/O into
existing PROFINET infrastructures or hybrid automation
architectures.
