Product Description

Description

Integrating separate EtherCAT control networks requires reliable, real-time data synchronization. The Beckhoff EL6695 serves as a high-performance EtherCAT bridge terminal, enabling bidirectional data exchange between two independent EtherCAT masters. Operating with a primary interface powered via the internal E-bus and a secondary interface utilizing a dedicated 100 Mbit/s RJ45 physical layer, this terminal bridges process data across separate networks without compromising deterministic system performance.

This bridge module is equipped with advanced Distributed Clocks (DC) support, allowing synchronization of subordinate clocks across network boundaries to a common reference clock. System engineers can configure process image sizes of up to 3 kbytes in each direction, depending on the master capability. The terminal also acts as a network gateway for mailbox protocols, supporting AoE (ADS over EtherCAT), EoE (Ethernet over EtherCAT), FoE (File over EtherCAT), and VoE (Vendor-specific over EtherCAT) transmissions.

Features

Dual-sided communication interface linking primary E-bus and secondary 100 Mbit/s RJ45 Ethernet ports.
Supports high-accuracy Distributed Clock (DC) synchronization across independent EtherCAT master segments.
Flexible PDO mapping supporting process image sizes up to 3 kbytes per direction (TwinCAT systems support up to 1400 bytes).
Comprehensive mailbox protocol support including AoE, EoE, FoE, and VoE.
Galvanic electrical isolation up to 500 V between the primary E-bus and the secondary side.
Integrated status LEDs for hardware diagnostics and network status monitoring.
Compact 24 mm terminal housing designed for standard 35 mm DIN rail mounting with double slot and key connection.

Applications

Synchronized multi-master systems in automotive assembly and advanced manufacturing lines.
Linking independent safety-rated and standard EtherCAT segments.
Process integration between packaging machines, test benches, and main supervisory PLCs.
Modular production cell networking requiring distributed clock consistency.
