XB-ET-31 ctrlX I/O Ethernet Switch Port Junction

📦 Product Overview: ctrlX I/O XB-ET-31

The XB-ET-31 is a specialized interface module within the ctrlX I/O portfolio designed to provide decentralized Ethernet connectivity. Unlike the XFE extension modules used directly on the XM controller, this module is a terminal-style component that sits within a modular ctrlX I/O station. It allows for the seamless integration of any standard Ethernet device into an EtherCAT-based I/O segment, forwarding data transparently via the EtherCAT local bus.

🔹 1. Description

The XB-ET-31 (Material Number: **R911419351**) serves as an Ethernet "switch port" within a terminal block. It captures standard Ethernet traffic from a connected device (such as a laptop, camera, or third-party sensor) and tunnels it through the EtherCAT network using the EoE (Ethernet over EtherCAT) protocol. This enables you to maintain a single cable architecture while still accessing non-EtherCAT devices located deep within your I/O stations.

🔹 3. Key Functions

🚀 Transparent Forwarding: Ethernet communication from connected devices is routed completely without collisions through the EtherCAT local bus to the master.

📡 Zero Configuration: The module is typically "plug-and-play" and does not require complex software addressing—it is recognized as an EoE participant by the controller.

🛠️ Flexible Placement: Can be installed at any position within a ctrlX I/O station, allowing you to drop an Ethernet port exactly where your peripheral hardware is located.

🛡️ Efficient Design: Extremely slim 20mm profile saves significant space in the control cabinet compared to standard industrial switches.

💾 Integrated Diagnostics: Features an RGB LED for visual status monitoring (e.g., indicating the EtherCAT state or local errors).

🔹 4. System Integration

📏 Mounting: Vertical installation on a standard 35mm horizontal DIN rail.

🔗 Logic Supply: The logic and peripheral voltage (UL/UP) as well as the module communication are routed through the internal backplane bus.

⚙️ Software Requirements: For integration into higher-level systems, the corresponding ESI (EtherCAT Slave Information) files must be imported into the engineering tool (e.g., ctrlX I/O Engineering or IndraWorks).
