Description

Engineered for high-performance industrial networking, the Beckhoff EL6631-0010 serves as a specialized PROFINET RT device interface within decentralized EtherCAT Terminal systems. This gateway module enables seamless data exchange between EtherCAT and PROFINET RT controllers, mapping up to 1000 bytes of input and output process data directly onto the E-bus.

The module features an integrated 2-port switch designed for 100BASE-TX Ethernet connections via standard RJ45 connectors. This dual-port switched configuration simplifies line topology deployment in complex automation systems. Through hardware diagnostics and status LEDs, operators receive real-time visibility into E-bus communication status, network link activity, and protocol diagnostics.

Features

Dual-port switched Ethernet interface (100BASE-TX) via RJ45 connectors.
Supports PROFINET RT device protocol with Conformance Class B.
Handles up to 1 kbyte of input and 1 kbyte of output process data.
Integrated LLDP and SNMP functions for physical topology detection and network diagnostics.
Minimum RT cycle time of 1 ms.
Robust 500 V electrical isolation between E-bus and Ethernet interfaces.

Applications

Decentralized factory automation systems.
Machine building and modular assembly lines.
Interfacing PROFINET RT master controllers with high-speed EtherCAT networks.
Process control systems requiring distributed network topology bridging.
